There is no shortage of 27-inch gaming monitors to choose from. This size strikes a balance between screen area and desktop footprint. But who would turn down a 32-inch panel when it comes to the best gaming monitors? No one I can think of. It requires a bit more room, but if you have it, it’s a screen size that lets you keep multiple apps open and edit documents side by side. It’s also a great window for the detailed graphical worlds found in today’s most popular games.

Larger screens always cost more than smaller ones, or do they? Following my recent review of AOC’s U27G4XM, a 27-inch 4K Mini LED panel that sells for $350, I have the U32G4. It also uses a 4K panel with a dual-refresh operation that toggles between 4K/160 Hz and FHD 320 Hz. It forgoes the Mini LED for an edge array, but in doing so, it actually costs less while being larger, 32 inches diagonal. It also has Adaptive-Sync, wide gamut color, and HDR. Let’s take a look.

AOC U32G4 Specs

The U32G4 starts with an IPS panel that’s both fast and full of contrast. I measured around 1,100:1, which is a little higher than average for the category. Keep in mind that an OLED with similar specs will cost you close to $1,000, so this AOC is a terrific bargain. Speed comes from a 160 Hz refresh rate and a decent overdrive. You also get backlight strobing that can be used in concert with Adaptive-Sync. That’s something usually reserved for high-end gaming screens. The dual-mode feature doubles the Hertz to 320 and sets the resolution to FHD (1920x1080). That’s a bit soft for such a large screen, but it nearly eliminates motion blur.

There’s plenty of color and brightness here with 480 nits available for SDR content. Contrast is solid with respectable black levels that are a little lower than the average IPS panel. No Quantum Dots are used, but color coverage is measured at 90% of DCI-P3. HDR10 content is supported, with a VESA DisplayHDR 400 rating. And three HDR emulation modes work to increase the dynamic range of SDR material.

Gamers get a nice set of extras, including aiming points with a dynamic option, sniper modes, and a frame counter. There are no LED lights, USB ports, or internal speakers. But you do get a precise four-level overdrive and the backlight strobe, which can be used along with Adaptive-Sync. That’s a boon for those who want to stay at 4K resolution but don’t have a fast enough video card to run at 160 fps. Of course, the 320 Hz/FHD option is just a button click away.

If you’re willing to give up the U27G4XM’s Mini LED backlight, the U32G4 represents a phenomenal value. $320 for a 32-inch 4K gaming monitor? That’s a deal well worth checking out.

Assembly and Accessories

The U32G4 ships in crumbly foam packaging, with the base, upright, and panel requiring toolless assembly. Once done, it’s a reasonably solid piece with a wide stance and good stability. The power supply is internal, so you get an IEC cord plus DisplayPort and HDMI cables.

Product 360

The U32G4’s styling is simple and elegant, with the panel’s shape formed from triangles in the back. A bright red trim ring encircles the fulcrum in the back and the words “AOC Gaming” appear as well. The cooling vents are hidden inside the gap you see at the top.

The screen has an 8 mm-wide flush bezel with a 20mm strip across the bottom. Under the right corner are four OSD control keys and a power toggle. A tiny status LED glows orange in standby and white when the power is on. The screen’s anti-glare layer keeps ambient light from spoiling the image while being clear and grain-free.

The stand is secure and tight in operation. It includes a red-trimmed cable hole that’s turned to the side, so it doesn’t show from the front. Ergonomics include a 5/23-degree tilt, 20-degree swivel, and a 5-inch height adjustment. You also get a 90-degree portrait mode. Movements are firm and smooth with little to no play. Though relatively lightweight, the U32G4 is a solid piece of gear.

There isn’t much happening on the I/O panel, except for a DisplayPort 1.4 port and two HDMI 2.1 ports. There are no internal speakers, but you can plug headphones into the 3.5mm jack. There are no USB ports or LED lighting. If you prefer to use a monitor arm, a 100mm VESA mount is provided with fasteners included.

OSD Features

To summon the U32G4’s OSD, press the right-most control key. Don’t press the power toggle by mistake, as I did several times. The menu is convenient and concise, and divided into seven sections.

The Game Setting menu starts with the dual mode feature, which includes 4K 120 Hz, 160 Hz, and FHD 320 Hz modes. The quicker way to switch is to press the second button, which pops up a quick menu and changes modes in a few seconds. You’ll need to visit the Nvidia or AMD control panel once to set each mode, then you can toggle back and forth at will.

There are also game modes in addition to the Eco picture modes. That makes for many possible combinations, so I suggest sticking with Standard/Standard for all content. It’s the closest to spec and calibrates to a high standard. This menu also offers shadow control for low-end gamma, a color saturation slider, a dial point (the aiming point, static or dynamic), and three sniper magnifications. The second screen has MBR and MBR Sync, which is the blur-reducing backlight strobe. Sync means you can use it along with Adaptive-Sync. There is a little phasing, but it is effective at keeping blur at bay when frame rates drop below 120fps. You can also turn on a frame rate indicator. The overdrive has four levels, of which Faster strikes the best balance between ghosting and blur reduction at 160fps.

The Picture menu contains the eight main picture modes. Standard works the best, and I used it for all testing and gameplay. You can adjust the color temp with fixed modes and a set of RGB sliders. There are five gamma presets, color management and three gamut options. Panel Native covers around 90% of DCI-P3 and is suitable for all SDR and HDR content. The sRGB mode is accurate enough to qualify for color-critical applications.

There are three HDR emulation modes that extend the perceived dynamic range of SDR content. When HDR10 signals are present, a fourth mode appears, Display HDR. It is the best choice for its accurate grayscale, EOTF, and color tracking.

The only other peripheral feature I noted here was PIP and PBP. You can view two sources at once and the PIP window can be moved and sized. You can swap the windows and select which one plays audio through the DisplayPort or HDMI inputs.

AOC U32G4 Calibration Settings

The U32G4 looked a tad warm to my eyes, and initial measurements showed it was a little short on blue in grayscale patterns. It can be used without calibration, but a few tweaks to the RGB sliders removed all visible errors. Gamma runs a shade dark on the 2.2 setting. Changing it to 2.0 was too much; it washed out the image. I noted that the sRGB mode had no calibration options, but it tracked grayscale and color with reasonable accuracy, though it showed a few gamma quirks. I’ll tell you more about that on page four. HDR signals have four modes available, with Display being the best choice. They cannot be calibrated. Below are my recommended SDR settings. Please enjoy.

Gaming and Hands-on

Right out of the gate, I could see how quick the U32G4 was. Even at a “mere” 160 Hz, it delivered smooth motion thanks to its precise and artifact-free overdrive. It’s one of the better implementations I’ve seen, especially at this price point. I used the Faster setting (third of four) and was rewarded with no perceivable motion blur. I was able to stay at 160fps thanks to a GeForce RTX 4090.

I tried the backlight strobe and found it effective at lower frame rates. I capped the action at 120 Hz and still had a smooth experience. It keeps Adaptive-Sync on, which is something I’m rarely able to do. There aren’t many monitors at any price that have that ability. If you have a slower video card, you can still enjoy 4K resolution at lower frame rates.

The dual-mode switch worked without issue once I set it up in the Nvidia control panel. You can toggle it in the OSD or press the second control key for a quick menu that does it faster. Running FHD on a 32-inch monitor is soft at best, but there’s no denying the benefit of 320fps. The U32G4 is quick at 160 Hz and super-quick at 320 Hz. This is also a good way to enjoy high frame rates from a budget gaming PC.

There are no Quantum Dots here, so I missed a little green saturation. But otherwise, the U32G4 is very colorful. DCI-P3 coverage is around 90%, so there is plenty of color for SDR content. The sRGB gamut option is useful when a smaller color space is needed, but I noticed slight gamma issues. Shadow areas were a bit light, and some highlights were muted. You can see why in the tests on page four.

For workday tasks, I stuck with Panel Native and a few tweaks to the RGB sliders to remove all grayscale errors. Gamma is a shade dark, but there is no loss of detail. Set the brightness slider to 200 nits, and you’ll enjoy a vivid and pleasing image.

4K at 32 inches has plenty of pixel density at 139ppi. That’s fine enough to hide the dot structure unless you sit inches from the screen. Text is smoothly rendered without visible jaggies. Graphics look realistic with photos being particularly enjoyable. That might have something to do with the large format. 32 inches is my go-to and it’s the size of my reference screen. It’s perfect for writing where I need to keep extra windows open to refer to charts and data. Spreadsheets can be viewed with much less scrolling, and webpages display more of their content too. Photoshop lets you see the picture and keep lots of toolbars at hand.

Takeaway: For $320, it’s hard to imagine a better 4K gaming monitor than the U32G4. It’s fast, bright, and colorful. It doesn’t have USB ports or internal speakers, but it does have all the goods for high-performance gaming with low input lag, smooth motion resolution, and accurate color. It’s equally adept at productivity with lots of screen area for documents and large, clear text. If you have the desktop space for something bigger, a 32-inch monitor is a great option.

For all tests except panel response, I’ll be comparing the U32G4 to a group of 27-inch 4K screens. My database doesn’t have any current 32-inchers except for BenQ’s PD3226G. The other displays are AOC’s U27G4XM, ViewSonic’s VX2730D-4K, Titan Army’s P2712V, and Gigabyte’s GS27U.

Pixel Response and Input Lag

Click here to read up on our pixel response and input lag testing procedures.

The response test group consists of the last five LCD panels I’ve tested, so their sizes and resolutions vary. It’s interesting to note that refresh rate doesn’t always mean faster screen draw. That is a function of the overdrive. When I test, I set it to where there are no ghosting artifacts. This is usually not the fastest setting. In the U32G4’s case, doubling the refresh rate adds a scant 0.16ms to the score. This is an imperceptible amount. The overdrive is effective, but the first three panels will be a touch smoother at the indicated refresh rates. Remember that an OLED panel is about ten times quicker with draw times around 0.25ms.

In the lag test, the U32G4 takes the win at 320 Hz with a 13.4ms score. This puts it on par with many premium gaming monitors. At 160 Hz, it manages to outdo three monitors with higher refresh rates. For the price, this kind of performance is hard to beat.

Test Takeaway: The U32G4 is one of the faster gaming monitors I’ve tested. It’s worth pairing with a video card powerful enough to run at 160 Hz at 4K resolution, as it offers excellent overdrive and very low input lag. To get smoother processing, you’ll need an OLED, which will cost you around three times as much. This is impressive performance to say the least.

Viewing Angles

The green tint seen in the U32G4’s 45-degree side photo shows its IPS origin. But it isn’t the most tint I’ve seen. And there is no change to gamma or brightness, which is a major plus. This is a very shareable monitor. The top view has a red cast with reduced gamma and luminance.

Screen Uniformity

To learn how we measure screen uniformity, click here.

I noticed a Uniformity picture mode, which indeed improves uniformity but at the cost of peak brightness and contrast. No matter, because my U32G4 sample scored an excellent 6.58% in its Standard mode. There are no visible issues here in any test pattern or content. This is excellent performance.

To read about our monitor tests in-depth, please check out Display Testing Explained: How We Test PC Monitors. We cover brightness and contrast testing on page two.

Uncalibrated – Maximum Backlight Level

The U32G4 is fairly bright for its size. Most 32-inch screens do well to hit 400 nits unless they have Mini LED backlights. At 480, the U32G4 is nearly as bright as its 27-inch Mini LED stablemate, the U27G4XM. If you use a 32-inch monitor at 480 nits, you will tire quickly unless your room is sunlit, or you’re outside, say in a location shoot tent. The black level is respectable for an IPS monitor, so you get 1,154.9:1 contrast, which is a tad above average. Only the ViewSonic boasts more dynamic range.

After Calibration to 200 nits

After calibration, the U32G4’s black level goes up to second place behind the overachieving VX2730D-4K, and contrast stays consistent at 1,147.4:1. ANSI contrast is also very consistent at 1,088.4:1, keeping it ahead of all but the ViewSonic in this group of tests. This is excellent performance.

Test Takeaway: You won’t mistake the U32G4 for an OLED or VA monitor, but among IPS screens, the most common tech, it stands out with solid contrast and good black levels. It also has high brightness, which is an asset for outdoor use or if you have a very sunny office like me.

The U32G4 is on the edge of needing calibration. I expect most users will be satisfied with the image as it comes out of the box. If you do tweak, stick to the Standard/Standard mode which allows access to RGB sliders, gamma presets and color gamut options.

Grayscale and Gamma Tracking

Our grayscale and gamma tests use Calman calibration software from Portrait Displays. We describe our grayscale and gamma tests in detail here.

In the first chart, you can see that the U32G4 is a tad warm in tone, but the errors are close to the 3dE threshold. Brightness levels below 50% have no visible issues. This is solid performance for the money. Gamma runs a tad dark with rising values in the 60-90% range. This is a small error that won’t adversely affect real-world content. Some highlights may look muted, but problems will be hard to spot.

Calibration tightens up grayscale tracking by bringing all errors below 2dE. You won’t see anything but perfectly neutral tones here. Gamma is a shade lighter too, which is a subtle but positive change. Considering that the U32G4 is a 32-inch 4K monitor for $320, I can’t complain.

The sRGB mode has similar grayscale tracking, but gamma is a bit askew. The dip at 10% means dark areas will be too light. As the values rise, it mutes highlight areas, especially in the 80-90% brightness region. The U32G4 can be considered qualified for critical applications, but some compensation for the gamma error should be made.

Comparisons

In the default comparison, the U32G4 sits right on the edge of “needs calibration.” I would say it does, but I’m pickier than most. It’s an occupational hazard. I doubt too many gamers would complain. But if you tweak, at least with my recommended settings, you’ll make visible gains in image quality. Not only are the neutral tones more neutral, but the gamma is also a tad lighter, which gives the picture more verve.

Though gamma is a shade dark, its tight range of values mitigates the visual impact of any inaccuracy. The range is small at 0.12 while the deviation is 3.64%. That equates to an actual value of 2.28, not too far from 2.2. This is excellent performance for a budget gaming monitor.

Color Gamut Accuracy

Our color gamut and volume testing use Portrait Displays’ Calman software. For details on our color gamut testing and volume calculations, click here.

The default color chart shows excellent tuning on AOC’s part, with only slight hue errors in magenta and cyan. Green comes up a tad short of full coverage thanks to the lack of Quantum Dots. The inner points hit their marks, but you only get around 85% of the green primary. This is typical of non-QD LCD panels.

Calibration corrects secondary hue errors without changing any saturation points. The improvement is subtle but visible. This is excellent performance.

The sRGB chart adheres well to the standard despite the gamma errors I noted earlier. This is why you can use the U32G4 for critical work. Gamma issues can be compensated for using a software profile if you wish.

Comparisons

This is a solid group of color-accurate monitors, with the U32G4 in fourth place. If you lined them all up, you’d see very little difference except for the top three, which cover more of the green primary. From a precision perspective, the U32G4 holds its own with more expensive displays. DCI-P3 coverage comes up a little short of 90%, but for the price, there is nothing to complain about. sRGB coverage is ideal at 99.32%.

Test Takeaway: The U32G4 is very accurate out of the box when price is considered. You’re getting a 32-inch 4K display for $320. That alone is enough. With calibration, it delivers solid accuracy with its only weakness being green primary coverage when referenced to DCI-P3. The sRGB mode has excellent gamut accuracy and only needs improvement to its gamma tracking. Overall, the U32G4’s color performance is more than good enough to satisfy users looking to save a bit of money on a large screen.

Our HDR benchmarking uses Portrait Displays’ Calman software. To learn about our HDR testing, see our breakdown of how we test PC monitors.

The U32G4 supports HDR10 content with an automatic switch and four specific picture modes. It can also mimic HDR’s dynamic range with three emulation modes for SDR signals.

HDR Brightness and Contrast

I was surprised to see that the U32G4’s HDR peak was a little lower than its SDR number. This isn’t a huge deal, but it does narrow the gap between SDR and HDR in terms of impact. I also noted that there was no dynamic contrast in play. There is no edge-zone or field dimming, and the DCR option in the picture menu is grayed out. This means there is no difference in black levels or contrast between SDR and HDR. In both modes, you get around 1,100:1. The U32G4 supports HDR but doesn’t embrace it. This is also true of the ViewSonic, Titan Army, and Gigabyte displays. If you want high-impact HDR from an LCD, go for a Mini LED screen like the U27G4XM.

Grayscale, EOTF and Color

In the HDR grayscale test, there is a slightly warm tone, but the error is barely visible in content. That’s a good thing because there are no adjustments available. The highest errors just crack 4dE, not bad for a budget display. The EOTF tracks very closely to the reference with a little lightness around 40-50% brightness and an elevated black level seen at the 0-5% part of the chart. The tone map transition at 65% is correct for the measured black and white thresholds.

The color test shows a little oversaturation, but no more than any other HDR monitor I’ve tested. This is a typical approach taken by most displays that gives HDR more punch. It’s effective in the U32G4’s case with no cause for complaint. Hue tracking is on point. The DCI-P3 chart is a tad short on green; also typical for non-Quantum Dot screens. In the BT.2020 test, the U32G4 runs out of color at 85% red, 70% green and 90% blue.

Test Takeaway: The U32G4 is a color-accurate HDR monitor but not a particularly bright or impactful one. It has no dynamic contrast available to extend that range but that isn’t unusual at this price point. The standard is supported with accurate color and luminance tracking, but HDR doesn’t look significantly different from SDR.

Now that 4K monitors are becoming available at truly attractive prices, the array of choices is vast. But it seems they’re mostly concentrated in the 27-inch category, if my review database is any indication. I doubt there are users who would choose a 27 over a 32 unless they just don’t have the room. 32 inches used to be a significant price jump, but no more. The AOC U32G4 is $320, and for that sum, you get a lot.

Its IPS panel has slightly higher than average contrast at around 1,100:1. Color is accurate with no real need for calibration, but you can tweak it for a small improvement. It’s bright at over 480 nits peak though HDR is a little less vivid at around 450 nits. And it doesn’t offer dynamic dimming so the quality difference between SDR and HDR is small. In all scenarios though, it is very colorful. You don’t get Quantum Dots, but you do get 90% coverage of DCI-P3.

Video processing is on par with many premium screens thanks to a precise overdrive and extremely low input lag. The U32G4 also lets you run backlight strobing with Adaptive-Sync, a feature that very few monitors offer. And the dual-mode feature works without issue if you want to race around at 320fps in FHD resolution.

If you only have a small monitor budget but want a large screen, the AOC U32G4 is pretty much a no-brainer. It’s fast, bright, and colorful, and games with the best monitors I’ve reviewed. It’s versatile too, with dual-refresh and MBR Sync. For $320, it has no real competition. Budget-conscious gaming PC owners should definitely check it out.

Samsung Display has announced that it is now supplying its first mass-produced VESA DisplayHDR True Black 1400 monitor panels to laptop makers including Lenovo, Asus, Dell, and MSI. Get ready for the brightest and punchiest portable displays yet as these big-name laptop brands integrate Samsung’s latest tandem OLED displays into their designs. VESA only introduced this new standard earlier this month, and it is notable for requiring panels with at least 40% higher brightness than the previous top tier.

The VESA DisplayHDR True Black 1400 specs are rather strenuous. Earning this certification means that your display must “reproduce black levels of 0.0005 nits or lower while achieving peak brightness of 1,400 nits at a 10% On Pixel Ratio (OPR),” notes Samsung. Peak brightness is also boosted by 40% compared to VESA’s previous highest certification level, True Black 1000. In terms of actual brightness readings, Samsung’s new tandem OLEDs offer up to 1,600 nits, which is 40% higher than the 1,100-nit peak brightness of conventional OLED panels with a single emissive layer.

In case you haven’t heard of tandem OLED display panels, a big clue to their boosted visual performance is in the name. This display architecture stacks two organic emissive layers to improve light-emitting efficiency and achieve higher brightness. Another benefit is that the dual operation of the panels means a “tandem OLED can produce greater brightness using the same current or reduce the load on each emissive layer at the same brightness level, extending the panel’s lifespan,” notes Samsung in today’s press release. Thus, this kind of panel isn’t necessarily going to crater your laptop battery life when you only require modest brightness levels, as in a typical home/office environment, for example.

Lenovo’s Yoga Pro 9i Aura Edition was the first device to feature Samsung’s new tandem OLED panel. Meanwhile, devices from Asus, Dell, and MSI are going to hit retail sometime in H2 this year.

We’ve already seen tandem OLED-enhanced desktop monitors launched from brands like Alienware, Gigabyte, and MSI. Samsung Display’s local rival, LG Display, is also gearing up to compete in this premium market segment.

TCL CSOT, a subsidiary of Chinese electronics and TV giant TCL, has been developing inkjet-printed (IJP) OLED displays since 2024, and it seems that it has finally brought it to market with the Lenovo Legion R9000P. Lenovo says that this is the first laptop in the world to feature the TCL CSOT technology, which marks a significant step towards “the commercialization of this next-generation display technology.”

This Lenovo Legion laptop will feature a 16-inch IJP OLED that can hit a 240 Hz refresh rate while also covering more than 99% of the DCI-P3 color gamut. This isn’t exactly groundbreaking when it comes to OLED monitors, but the biggest advantage that IJP OLED displays have over the traditional vacuum thermal evaporation (VTE) method is that it’s cheaper and simpler to produce, resulting in higher yields. TCL CSOT’s IJP OLEDs also promise improved brightness, which is something that traditional OLED screens struggle with. This is especially important for laptops like the Legion R9000P, which are expected to face more varied lighting conditions due to their portable nature, compared to monitors and TVs that are often placed statically in one location for most of their lifetime.

If this technology catches on, it should reduce the cost of the best OLED gaming monitors, which, arguably, offer one of the best experiences when it comes to contrast and color. Unfortunately, Lenovo hasn’t revealed the specifications or the price of the Legion R9000P, so we cannot say for sure how the IJP OLED has affected its affordability and compare it with similar models that feature a more traditional OLED display.

While this is the first time that IJP OLED is being mass-produced for consumer electronics, TCL CSOT has been working on the technology for over 10 years now. In fact, the company has been mass-producing its 5.5-generation IJP OLED since 2024 (which is presumably used in commercial and industrial products like medical displays) and has started construction of its 8.6-generation IJP OLED production last year.

Aside from Lenovo, MSI is also using this new IJP OLED panel in the just-announced MSI Pro Max OLED 271UPJW12. While the company did not explicitly mention that it used a display from TCL CSOT, its specifications exactly match. Besides that, TCL CSOT is currently the only one manufacturing OLED screens using the inkjet printing technique.

MSI Unveils the PRO MAX OLED 271UPJW12: The World's First 27-Inch 4K IJP OLED Monitor from r/OLED_Gaming

Aside from laptops and monitors, we also expect to see this technology to eventually reach TVs and smartphones. This should make high-quality OLED TVs more affordable to more users and compete against cheaper TVs that use technologies like QLED and Mini LED. It could also allow for budget phones with beautiful screens that can give flagship models a run for their money.

Of the many sizes and shapes the best gaming monitors come in, the 34-inch ultra-wide 21:9 screen strikes a good balance between size and player immersion. It’s wider than the 32-inch 16:9 format but not as large as extreme displays like the 52-inch LG I reviewed recently.

What makes them even better is QD-OLED technology, and there, Alienware is offering a nice update to last year’s AW3425DW. It’s the AW3426DW, and it brings a few new features, like a five-layer tandem OLED for higher light output, V-stripe RGB sub-pixels for sharper rendering, a bump from 240 to 280 Hz, and a new anti-reflective screen coating. It’s still WQHD 3440x1440 pixels, and it still offers Adaptive-Sync, HDR10, and wide gamut color, and adds Dolby Vision to its list of supported content. Let’s take a look.

Alienware AW3426DW Specs

The AW3426DW’s Tandem OLED is a new variant of the technology that takes the simple approach of stacking multiple OLED layers for greater light output with less energy consumption. It also taxes the layers less, so they last longer and are more resistant to burn-in. Alienware backs this with a three-year warranty that includes burn-in. The screen has a 34-inch diagonal, a 21:9 aspect ratio, a 1800mm curve radius, and WQHD (3440x1440) resolution.

V-Stripe RGB refers to the sub-pixel layout, which is finer and more precisely applied. This makes fine text and detail sharper by reducing color fringing. With its five OLED layers, the AW3426DW now boasts higher light output than last year’s model. The VESA DisplayHDR rating is now 500 nits for a full white field and 1,300 nits for a 3% window. To cap off the imaging improvements, there’s a new anti-glare coating applied to the screen that further deepens black levels and more effectively rejects ambient light.

With 280 Hz instead of last year’s 240, the AW3426DW is a tad speedier, and my test results, which you’ll see on the next page, show a nice drop in input lag. Panel response is typical OLED-quick, resulting in perfect motion resolution and smooth action free of motion blur. Adaptive-Sync is also supported on both Nvidia and AMD platforms.

It’s no surprise that the AW3426DW supports HDR10, but now it adds Dolby Vision to the mix. The benefits of its dynamic tone mapping cannot be understated. HDR10’s tone mapping is fixed to the content metadata, which usually has a peak of 1,000 nits. If a display can’t hit 1,000 nits, or its output exceeds that, it must tone map to render all brightness steps. Dolby Vision controls this process within the content and always knows the display's actual output level. Bottom line: it’s more accurate and consistent, and it looks better. It’s a difference you can plainly see. Dolby Vision isn’t common in games, but it is common from streaming services like Netflix, HBO Max, and Disney+.

All other features of the AW3425DW carry over to the AW3426DW, like AlienVision and its cool aiming point/sniper mode editor. You also get USB ports and a backlit Alienware logo on the back. There’s no headphone jack or internal speaker, but the downstream USB-A and USB-C ports are on the bottom edge of the panel, where they are within easy reach. Video inputs include two HDMI and a DisplayPort.

Assembly and Accessories

The AW3426DW arrived in secure molded pulp packaging that is completely recyclable. The base, upright, and panel assemble easily with no tools needed. The power supply is internal, so you get IEC power plus HDMI, DisplayPort, and USB cables. A small microfiber cloth is provided to keep that beautiful screen free of dust and fingerprints.

Product 360

The AW3426DW maintains the aesthetic Alienware introduced last year with softly rounded corners and smooth tapers. My favorite bit is where the upright and base meet; the joint appears to float with a slender swivel point that’s barely visible. In the back is a backlit Alienware head and a polished symbol; “Alienware 30” is the official term. The head can light up with different colors and effects. A subtle vent rings the fulcrum with small perforations that keep the internals cool. A graphite layer behind the OLEDs further cools the screen.

The side photo affords a good view of the rounded aesthetic. The stand has no angles or corners at all, just a small cable hole to keep wiring tidy. Ergonomics include a 5/21-degree tilt and a 20-degree swivel. The height range is 4.4 inches, and there is no portrait mode. Movements are firm and free of play. Build quality is premium in every respect. If you’d rather not use the stand, there is a 100mm VESA mount with fasteners included.

Underneath, you’ll find a small I/O panel with two HDMI 2.1 ports and a DisplayPort 1.4 with Display Stream Compression (DSC). A USB upstream port supports the two downstream jacks on the panel’s edge. You get a USB Type-A and Type-C. The Type-C port supports charging and peripherals, but not video. In the center, you can see the OSD joystick that controls all monitor functions.

OSD Features

Pressing the AW3426DW’s joystick opens a quick menu at the bottom of the screen with a large status bar at the top. It shows input signal info along with the current picture mode, HDR status, panel health, and dark stabilizer setting. The quick menu has five icons that scroll left to right. They can be programmed for many different monitor functions, such as brightness/contrast, input, AlienVision, HDR, and others. Clicking the joystick up opens the full OSD.

In the Game menu, you can choose from 13 picture modes. Standard works well by default and does not require calibration if you’re OK with using the full color gamut in SDR mode. It covers 105% of DCI-P3. If you want to make adjustments, select Custom Color, where you get RGB gain/bias and color management. To access sRGB, there’s a Creator mode with a gamut selector and gamma presets.

Game Enhance Mode contains a timer, frame counter, and alignment marks, but where are the aiming points? That’s one of the coolest features of the AW3426DW, it’s called AlienVision, and it is a completely customizable set of reticles and sniper modes, eight parameters in all, that can be edited and combined in hundreds of ways to create a custom view of the game environment. Once configured, there are three memories so you can have setups for different games.

In the AlienFX Lighting menu, you can customize the behavior of the power button and the Alienware head on the back. There are lots of color and effect options, and you can turn on Aurora, which coordinates the lights with what’s happening on screen. You’ll need Alienware Command Center and a USB connection to make that happen.

The Display menu has seven HDR modes for HDR10 content, including a tweakable Custom Color option. I found decent accuracy in both Desktop and HDR Peak 1300 Bright modes. I’ll tell you more about that on page five. You can also toggle Dolby Vision on and off here.

The AW3426DW includes PIP and PBP with options for window size and position. In Personalize, you can specify the functions of the five quick menu icons and the four joystick directions. This makes it easy to quickly change something like the input or the picture mode.

OLED care is much simpler now than in previous models. Functions like logo detection and pixel orbiting are handled automatically by the AW3426DW’s firmware. The only thing you can do manually is pixel refresh. This menu also has a factory reset option. In the Information menu, you’ll find an 11-page calibration report for each monitor, along with signal information and support resources.

Alienware AW3426DW Calibration Settings

Calibrating the AW3426DW is completely unnecessary. Just leave it in the default Standard mode and set brightness to taste. There is no variable brightness for SDR, so only one value is needed. If you want to calibrate, choose Custom Color. It has RGB gain and bias, plus hue and saturation sliders for each color. To change the gamut, use Creator mode. It lets you specify sRGB or P3 and includes five gamma presets. In the three Game modes, you can also adjust color and specify a custom value for the dark stabilizer. My SDR settings are included below.

For HDR content, there are seven more modes. Desktop is the default and is similar to HDR Peak 1300 Bright in its color and luminance tracking. The latter delivers the brightest highlights and the most vivid color.

Gaming and Hands-on

I suspect that some readers here will be wondering if the AW3426DW is a worthwhile upgrade over the AW3425DW. After several days of gaming and working, I will say that it is. HDR is brighter, and the new panel with its V-Strip RGB pixel structure is clearer than before. It’s hard to quantify this since OLEDs are sharp by nature, but the AW3426DW does make an incremental improvement. Brighter HDR certainly makes an impact with highlights that pop and a dimensional quality that no premium Mini LED can match.

Color accuracy is superb both out of the box and after calibration, where I changed just two settings, one click each. The AW3426DW is truly factory-calibrated. It equals any professional monitor in terms of measured performance and image fidelity.

Gaming was an addictive experience, as it is with any fast OLED. The smooth motion that comes with panel response, measured in fractions of a millisecond, is something you can’t get from an LCD. An OLED draws the screen about 10 times faster than an LCD with an equal refresh rate. The AW3426DW’s bump to 280 Hz is also a reason to upgrade. It reduces my input lag by 4ms in my test. Could I spot that difference in gameplay? No, but I’m not a competition gamer either. Those looking for every advantage will want to give this monitor an audition.

The 34-inch curved panel proved useful for both work and entertainment. It’s just large enough for me to display two documents side by side. It requires a bit more scrolling than my 16:9 32-inch screen, but the 1800R curve isn’t too severe. There was no image distortion, but I got a nice wraparound effect when navigating first-person shooters and graphical adventures.

I appreciated the inclusion of USB ports, especially the two located on the bottom edge of the panel. It’s easy to plug in peripherals or charge a phone from the USB-C port. But I missed the 3.5mm headphone jack. And there are no internal speakers, so to get audio, you’ll need USB-capable headphones or a desktop amplifier if you want to drive cabinet speakers. And I enjoyed the AlienFX feature with its glowing Alien head. It played colors off the wall behind my desk.

Takeaway: The AW3426DW is a worthy upgrade from the AW3425DW. It’s quicker and brighter, and the image is a tad sharper than before. Input lag is lower as well, which will appeal to skilled gamers looking for every possible advantage. Color is saturated and vivid with accuracy good enough to use right out of the box. The screen’s curve strikes an ideal balance between immersion and a square image.

To compare the AW3426DW’s performance, I’ve included its predecessor, the AW3425DW, along with Asus’ PG34WCDN, Acer’s X34 OLED, AOC’s AG346UCD, and Gigabyte’s MO34WQC2. The response chart is a different group of OLEDs owing to my recent acquisition of the Nvidia LDAT tester. It includes Acer’s X27 X1, ViewSonic’s VX2738-2K, MSI’s MPG 322UR X24, Asus PG34WCDN, and Alienware’s AW2726DM.

Pixel Response and Input Lag

Click here to read up on our pixel response and input lag testing procedures.

OLED panel response times are extremely tight, and in practice, you’re unlikely to see a difference unless frame rates are low. A panel like the AW3426DW, with its 0.24ms draw time, will retain smooth motion resolution down to about 160 fps. A faster panel like the Acer can maintain blur-free operation up to around 140 fps. If your video card can keep the action above 200 Hz, all the panels will perform equally from a visual standpoint.

In the lag test, the AW3426DW is among the fastest panels I’ve tested. The Asus is an extreme overachiever. Only a couple of other monitors can approach 10ms in my test. 14.1ms is very fast, more than enough for pro-level competition. And it’s a tad quicker than last year’s AW3425DW. Most gamers will be satisfied with the AOC and Gigabyte screens at 22ms. Remember that the fastest human reaction time is typically around 100ms.

Test Takeaway: The AW3426DW improves slightly over its predecessor, with nearly 4ms less input lag. Its panel response is on par with the other fast OLEDs I’ve tested. Motion resolution is extremely high, with moving objects rendering blur-free. It is fast and smooth enough for pro-level competition.

Viewing Angles

Most Quantum Dot OLEDs show a slight tint in 45-degree-angle photos, but the AW3426DW’s tandem OLED tech seems to have eliminated that issue. There is no change to gamma or brightness either. This is about as good as it can possibly be. Viewing angles up to 45 degrees are visually perfect. The top view has a slight red shift with a 10% brightness drop and reduced gamma.

Screen Uniformity

To learn how we measure screen uniformity, click here.

Fittingly, the AW3426DW aces my uniformity test and is bested only by its predecessor, the AW3425DW. Visually, there is no difference here. You won’t see any variation among these screens, as they are all below the visible threshold of 10%. It doesn’t get better than that.

Uncalibrated – Maximum Backlight Level

The AW3426DW is a bit brighter than last year, with over 320 nits peak for SDR. That’s from a full field white pattern. There is no variable brightness option, so you’ll see the same number from smaller windows and highlights in actual content. This does not reduce the impact of OLED’s infinite contrast and its unmeasurable black levels. The new anti-glare layer and five-layer Tandem OLED are said to lower black levels, but to the naked eye, they were already as black as black gets.

After Calibration to 200 nits

Calibration doesn’t change the black level or contrast result. It still cannot be measured. You’ll only need one brightness value since there’s no variable option. That comes into play for HDR content, though. ANSI, or intra-image contrast, also cannot be measured.

Test Takeaway: The AW3426DW offers the same black level and contrast performance as any OLED. That said, its new anti-glare layer offers better light rejection, which improves the perception of blacks in environments with medium to high ambient light levels. That is a visual observation that I cannot measure with instruments. One point in favor of upgrading your AW3425DW to an AW3426DW is the extra 60 nits of peak brightness it offers.

The AW3426DW came to me set to Standard picture mode, which, as you’ll see, does not need calibration. There is an 11-page report stored in each sample’s firmware that you can read from the OSD. My tests confirmed that it is indeed calibrated at the factory.

Grayscale and Gamma Tracking

Our grayscale and gamma tests use Calman calibration software from Portrait Displays. We describe our grayscale and gamma tests in detail here.

If I were just going to put the AW3426DW on my desk and use it for gaming and productivity, I would not bother with adjustments. The first chart shows that it has no grayscale errors above 2dE, and the gamma is slightly dark but very close to the 2.2 reference. This is impressive out-of-box performance.

In the Custom Color mode, you get RGB gain and bias sliders. I didn’t have to touch the bias, but I lowered red and green gain by one click each. The result was all errors below 0.5dE and a slightly tighter gamma. The visual difference is extremely small, but if you have the desire and the means, why not? This is a superlative performance.

The Creator sRGB mode has very accurate grayscale, but gamma is a tad wonky. It’s too light at 10%, making the shadow areas less black. And there’s a rise between 60 and 80%, which takes a bit of definition out of the brighter mid-tones. This is a minor error, but it would be nice to have tighter gamma. You can change the preset, but you can’t alter the curve’s shape.

Comparisons

Though the AW3426DW impresses with a 1.46dE default grayscale score, it is slightly bested by its predecessor and by the Gigabyte. These numbers are more like talking points as the visual difference can’t be seen with the naked eye. But I am here to be precise in my testing.

Calibration takes the AW3426DW down to 0.44dE, but again, it is pipped by the AW3425DW by 0.01dE. Yes, that is a hair at best. All the monitors here test extremely well.

Gamma performance is excellent but middling by comparison. The range of values is very tight at 0.08 from lowest to highest. The deviation is 2.73% with an actual average of 2.26. This is excellent performance.

Color Gamut Accuracy

Our color gamut and volume testing use Portrait Displays’ Calman software. For details on our color gamut testing and volume calculations, click here.

The color test result clearly shows the advantage of Quantum Dot technology. The AW3426DW fully covers all primaries, including green with slight oversaturation at all points. This means the picture will be very colorful but also well-balanced. Calibration barely makes a difference, but you can see slightly better hue tracking in cyan, magenta, and yellow.

The sRGB chart is very good overall, but with some slight undersaturation in the midrange red tones. This is an extremely small error. The AW3426DW is qualified for color-critical applications.

Comparisons

The color difference between all six monitors is extremely small. From an error standpoint, there is no visible difference. The only variation comes in the volume test, where the AW3426DW sits at the bottom of the Quantum Dot screens. It has about 1.5% less color volume than the AW3425DW, which is an invisible difference. The AOC and Gigabyte screens have a touch more green and red, but you’ll only see that in the brightest content. For everyday games, videos, and applications, all six monitors will look the same.

Test Takeaway: The AW3426DW has exemplary out-of-box color, grayscale, and gamma accuracy. It does not need calibration, but a couple of tweaks generated awesome numbers in my tests. Its color volume is on par with other Quantum Dot screens at a hair shy of 105% of DCI-P3. No one would complain about its colorful and clear image.

Our HDR benchmarking uses Portrait Displays’ Calman software. To learn about our HDR testing, see our breakdown of how we test PC monitors.

The AW3426DW offers higher brightness than its predecessor for both SDR and HDR content. It’s rated for 1,300 nits from a 3% window and certified by VESA for DisplayHDR 500. HDR10 signals get seven specific modes, and it supports Dolby Vision.

HDR Brightness and Contrast

For my tests, I measured HDR10 performance and noted a 70-nit higher peak for the AW3426DW over the AW3425DW. This is from a 25% window pattern. A 3% window is claimed at 1,300 nits, and this result leaves no reason for doubt. The AW3426DW is definitely brighter than before, and its HDR is more impactful. Variable brightness is in play here and cannot be turned off, not that you’d want to. This is excellent performance.

Grayscale, EOTF and Color

I measured the Desktop and HDR Peak 1300 Bright modes and got similar color and grayscale results. There are no visible errors in the first chart, and EOTF tracking is solid. The trace starts a tad dark, but I could still see all the steps in a test pattern. Shadow detail is clear and visible in all cases. The tone map transition is at 65%, which is correct for the measured white and black thresholds.

In the color gamut test, the AW3426DW uses all available coverage with extra saturation for P3 and almost 80% coverage of BT.2020. All points are slightly oversaturated, which is typical of the HDR monitors I’ve tested. They all push the envelope for extra impact, and it is effective. In the BT.2020 chart, the AW3426DW runs out of color at 90% red, 75% green, and 95% blue.

Test Takeaway: The AW3426DW presents a stunning HDR image with deep blacks and very bright highlights. It is a clear improvement over the AW3425DW. If you enjoy a lot of HDR content, it’s a worthwhile upgrade. Color and grayscale are very accurate in both Desktop and Peak 1300 modes.

The benefits of 34-inch 21:9 curved gaming monitors are many when compared to the vast array of sizes and shapes currently available. Play is enhanced by a screen that mimics VR headsets by encompassing the viewer’s peripheral vision. And this size doesn’t have a huge footprint. While jumbo screens are cool, they demand a larger desktop and can be costly. The AW3426DW strikes a good balance between usability, performance and cost. At this writing, it’s brand new to the market with an opening price of $800, the same as last year’s AW3425DW.

The AW3426DW offers several compelling reasons to upgrade. It’s brighter for both SDR and HDR content by around 60 and 70 nits, respectively. It also boasts much brighter small highlights for HDR, around 1,300 nits for a 3% window. This is thanks to its new five-layer Tandem OLED tech. Color remains vivid, with 105% DCI-P3 coverage from its Quantum Dot layer.

Speed has increased from 240 to 280 Hz, and that brings with it a 4ms drop in input lag, about 22%. That will be worthwhile to the most skilled gamers who want every possible advantage. The new anti-glare coating helps keep the image solid in bright rooms. And the V-Stripe RGB sub-pixel layout sharpens fine detail and text better as well.

At $800, the AW3426DW is a solid value among OLED gaming monitors. If you already own an AW3425DW, it’s worth upgrading for the improvements in speed, brightness and clarity. If you’re looking for your first OLED, it’s a great choice for all-around use, work, and play that is worth checking out.

A high-spec gaming monitor at a budget-friendly price could be yours, if you're quick. Amazon has dropped this 27-inch Samsung Odyssey G53F display down in price to just $169.99, setting you up with a display that's ready for high-end gaming at 1440p.

● Check out this deal on Amazon

It hasn't been this cheap in some time, according to Camelcamelcamel's data, with a price rising as high as $249.99 just one month ago. The saving here makes this a really affordable option for gamers who want a display from a trusted brand without compromising on specs. This Samsung Odyssey G53F monitor comes with an IPS panel, offering a 1440p top display resolution and a 200Hz refresh rate.

The refresh rate is an important point to mention for gaming, as this will ensure that you can play games at a high enough refresh rate without screen tearing, as long as your GPU is capable enough.

IPS panels, like the one in this Samsung display, are typically good all-rounders, as they offer the best viewing angles compared to (now cheaper) VA and TN rivals. The 1440p resolution means you can set your in-game resolutions to as high as 2,560 x 1,440, but this is a 27-inch monitor, meaning you'll have a higher pixel density at 1440p on this display than a bigger 32-inch alternative, giving you much sharper visuals overall.

If you're upgrading from 1080p, you'll notice a big difference in the quality of your graphics, and HDR10 support means you can enable HDR in-game for deeper contrast levels and more vivid colors. This display also supports AMD FreeSync Premium, a functionality that will allow you to completely eliminate screen tearing by syncing the monitor's refresh rate up to the GPU's frame rate output. Nvidia G-Sync support isn't officially mentioned, but it does often work with FreeSync-enabled displays, although it isn't something that we can guarantee will work here.

The G53F is a worthy upgrade for a PC, but it has one HDMI 2.0 and one DisplayPort 1.4 connection available, so you could hook it up to an extra laptop, handheld, or game console. It has auto-source switching functionality, too, which means that the monitor will automatically change inputs when a new device is plugged in or switched on, making it easier to use with multiple devices.

The $169.99 sale price for the Samsung Odyssey G53F gaming monitor on sale here is a good option. It's a 1440p monitor from a known and trusted brand with a high refresh rate, making it ideal for a budget-friendly modern gaming rig. This 32% discount might not be around for long, however, so make sure to pick it up before the sale runs out.

E-ink displays have come a long way since their introduction, with advancements in refresh rates and colors allowing them to be used as monitors for PCs. Bigme is once again pushing e-ink monitor technology with the 25.3-inch Bigme B251 Pro, which is on sale on its website for $1,279.00 (down from $1,599.00). This isn’t the first color e-ink monitor, as Dasung previously launched the first one in 2023, while e-ink device manufacturer Boox also debuted its 25.3-inch option last year. Nevertheless, what made the B251 Pro different is its claimed 60 FPS refresh rate.

This is the fastest claimed refresh rate we’ve seen so far on an e-ink monitor, with the previous record sitting at just 33 Hz. That doesn’t mean that you can start gaming on an e-ink display, though. VideoCardz points out that displays like these still face slow pixel response rates, latency, ghosting, and image quality issues, especially during fast motion, so it’s better to stick with the best gaming monitors if you need a monitor for competitive gaming. Nevertheless, this might be a viable solution if you have a text-heavy workload and have grown tired of dealing with strained eyes at the end of the workday.

Its 3200 x 1800 resolution, paired with a 25.3-inch screen size, gives it 145 DPI, which is slightly better than the 92 to 93 PPI you’d get from a 24-inch Full HD display. It also supports 4096 colors and 16 gray levels — although this is miles away from the millions of colors that modern monitors support, but that is the limitation that e-ink monitors face for now. The Bigme B521 Pro offers HDMI or DP connectivity, but also comes with wireless screen mirroring and a remote control. It also has a built-in front light with adjustable temperature, allowing you to use it in the dark without requiring an external light source.

The Bigme B251 Pro is an interesting development in e-ink technologies, and it would be nice to see if it can actually deliver a usable experience outside of reading. While we doubt its capabilities when it comes to gaming, we still want to see if it’s a usable alternative for productivity. Those on a budget will likely be deterred from buying it, though, especially as its high price point makes it more expensive than some of the best 4K gaming monitors you can buy today.

The ongoing component crisis has skyrocketed the cost of PC building, with most hardware being overpriced to oblivion as we speak. However, some product segments remain unaffected, such as gaming monitors. We've found a deal on an awesome 27-inch QD-OLED screen from Asus featuring 1440p resolution and a 240 Hz refresh rate for just $349 at Walmart right now. That's about 34% off its usual retail price of $529.

A 3rd Gen QD-OLED panel powers the Asus ROG Strix XG27AQDMESZ, so it has better color vibrance than similar WOLED panels. If you play in a lot of ambient light, the panel will show higher black levels that look purple, so just keep that in mind before making your purchase. It's also very glossy, which helps with perceived contrast and punchiness, but has worse reflection handling.

The claim to fame for this model in particular is the inclusion of a ''Neo Proximity' sensor that can automatically turn off the display if you step away from it. This is meant to help alleviate the infamous burn-in issue associated with OLED technology without you having to baby the monitor consciously. The proximity sensor is located in the chin of the display, so it can detect if someone is sitting in front of it. ASUS also includes its OLED Care Pro functions, which provide software-based mitigations in the OSD.

Spec-wise, we're looking at 99% coverage of the DCI-P3 color space and an average Delta-E of less than 2, so it's suitable for professional work out of the box. The monitor has one DisplayPort 1.4 port and one HDMI 2.1 port, with a headphone jack. Since it's an OLED, it has an instantaneous response time of 0.03 ms, and Asus has a bunch of anti-flicker features built in, along with Extreme Low Motion Blur (ELMB).

We've already mentioned that it's a 27-inch 1440p panel with a 240 Hz refresh rate, so it strikes a balance between cost and performance. It's plenty sharp and absurdly fast without breaking the bank. For just $349 on Walmart right now, you can't find another OLED monitor that's as feature-rich as the Asus ROG Strix XG27AQDMESZ.

In the enthusiast market, the most shopped-for monitor category is, without a doubt, 4K, specifically in the 27- and 32-inch sizes. The density of 3840x2160 pixels in these two screen formats is, put simply, where you stop seeing the dots. This makes anything look better, be it graphics, photos, documents, videos, or games. And once you’ve experienced it, you can’t go back to QHD or FHD.

The hurdle to resolution nirvana used to be price, but today there are plenty of 4K monitors available for less than $500. But for gamers, the question of frame rates remains. Yes, you can buy a fast 4K monitor, but how much will you have to spend on an equally fast video card? Moving 8.3 million pixels at 200fps is expensive. Luckily, there is a solution – the dual-mode display.

This is a fairly new trend where you get one of the best 4K gaming monitors that can switch to FHD and double its refresh rate with the push of a button. I’ve already reviewed a number of them, and here's AOC’s latest entry, the U27G4XM. It’s a 27-inch IPS screen with 160 Hz, 320 Hz in FHD, Adaptive-Sync, a full-array local-dimming Mini LED backlight with 1,152 zones, wide-gamut color, and DisplayHDR 1000. Let’s take a look.

AOC U27G4XM Specs

The U27G4XM maximizes the nit-to-dollar ratio with a full-array Mini LED IPS panel that has 1,152 local dimming zones. There are three different settings that reduce the black level to increase contrast. This gets the monitor closer to the broad contrast delivered by an OLED at a lower cost, and with higher brightness. DisplayHDR 1000 means a 25% window pattern will exceed 1,000 nits peak, and the U27G4XM achieves this with over 1,100 nits measured from my review sample. Black levels can go all the way down to the backlight being turned off (unmeasurable), but with local dimming on medium, I saw just over 13,000:1.

There’s plenty of color saturation that covers a measured 109% of the DCI-P3 gamut, and that’s without the benefit of Quantum Dots. The U27G4XM is reasonably accurate out of the box, but a quick calibration takes it to reference-level. And there’s a spot-on sRGB mode that’s suitable for color-critical tasks.

The dual-mode feature is a one-button affair that switches between 4K/160 Hz and FHD/320 Hz. It’s great for systems without a high-end video card. To run 160 fps at a game’s max detail level in 4K will require a GeForce RTX 4090. But you can run 320 fps in FHD with a cheaper GeForce RTX 4070 Ti Super. So, what you save on the video card will buy you the U27G4XM with a few bucks left over for a nice mouse and keyboard.

At this writing, that price is $350, which gets you terrific performance and a bright, colorful image. It also includes aiming points, sniper modes, and a frame counter. There are plenty of image modes and HDR support, with four presets for HDR10 content. You even get side USB ports, which I haven’t seen in a long time. The only things missing are LED lights and internal speakers. But you get a 3.5mm headphone jack alongside the HDMI 2.1 and DisplayPort 1.4 inputs, all of which support Display Stream Compression (DSC). On paper, the U27G4XM is an impressive package. Let’s see how it performs.

Assembly and Accessories

The U27G4XM comes in fully recyclable packaging, with molded pulp that protects the contents. The panel, upright, and base assemble without tools into a lightweight setup that fits easily on the average desktop. The accessory bundle includes IEC for the internal power supply, plus nice HDMI and DisplayPort cables.

Product 360

The U27G4XM goes for a chiseled look with flat, angular surfaces making up the back of the panel and an all-screen configuration in the front. Bits of red trim outline the stand’s fulcrum and the offset cable hole in the upright. This is unique in that it’s turned to the side, so you don’t see through it if you’re not using it. The base is cast aluminum with a wide stance and solid construction. The panel snaps on, and though the fulcrum looks large, it’s a little wobbly. It’s perfectly secure, but there is some play when you tilt or rotate the screen. Ergonomics include a 5/23-degree tilt, 20-degree swivel, a 90-degree portrait mode, and a 5.3-inch height range. If you want to use an arm, there’s a 100mm VESA mount with fasteners included.

The front bezel is thin and flush with just a small AOC logo at the bottom. The OSD is controlled by buttons rather than a joystick, a move that probably helped drop the price a tad. A tiny LED indicates power status with a soft glow. The anti-glare layer has a 3H hardness and is free of visible grain.

The input panel is up and under and features two HDMI 2.1 ports and a DisplayPort 1.4 hookup. All ports have DSC and work at full resolution and refresh. There are two USBs here, too, an upstream and a downstream. Three more downstreams grace the right side for easy access. This is a rarity nowadays, and I’m glad to see a nod to convenience from a budget display. There are no internal speakers, but you get a 3.5mm jack for headphones.

OSD Features

The U27G4XM’s OSD is controlled by a row of buttons, which, by modern standards, is a little old-school. But you get one-button access to the refresh mode switch, which is nice.

The dual-resolution feature is up first in the U27G4XM’s Game Setting menu. The easier way to do it is with the second control key, which pops up a little selector. The switch takes a few seconds once you’ve set it up in Nvidia or AMD’s control panel. Also, there are seven picture modes, Standard is the default and best. You also get shadow control to brighten up dark parts of the image, general color saturation, aiming points, sniper modes, a five-level overdrive and a frame counter.

The Picture menu has eight more image modes, which is a bit confusing since you can theoretically combine them with the Game modes for hundreds of combinations. I recommend sticking with Standard/Standard for all content. There are three gamma presets plus fixed color temps and RGB sliders. HDR gets four modes, three of which can be used as emulators for SDR content. HDR10 signals add a mode called Display HDR, which is fairly accurate for color and luminance tracking. Local Dimming gets three levels of aggressiveness. Each further lowers the black level while leaving peak brightness unchanged. Strong turns off the backlight completely under zero signal conditions. You can also choose the sRGB color space here. This mode is very accurate and can be used for critical applications. The U27G4XM also has a PIP/PBP feature for the viewing of two sources at once. The PIP window can be sized and moved.

AOC U27G4XM Calibration Settings

The U27G4XM can be used without calibration in its Standard picture mode. You can use local dimming for SDR and HDR content if you like. The medium setting increases the contrast ratio to around 13,000:1 for HDR and 1,600:1 for SDR content. I improved grayscale tracking to reference level with a few tweaks to the RGB sliders. I also noted that the sRGB mode is spot-on out of the box if you need the smaller gamut. The native color space covers just over 109% of DCI-P3. Local dimming does not change peak brightness, only black levels, so the brightness values below work in all dimming modes.

Gaming and Hands-on

After spending time with the U27G4XM playing games and getting through some work, I found that I only had two minor complaints. The stand, while secure, has a wobbly fulcrum where the panel attaches. This isn’t a big deal except when operating the OSD, which ties into my second nitpick. I am so spoiled by joysticks that on the rare occasion I get control buttons, I am sad. I realize that this is a budget monitor and at that vocation it excels. But pressing the arrow keys while the panel jiggles about is annoying.

These things aside, the U27G4XM is close to flawless. I’ve noticed that budget 4K screens have been getting quicker with each new model I review. This is the fastest one I’ve seen to date with extremely low input lag and smooth panel response from an excellent overdrive. Though 4K tops out at a mere 160fps, it is free of blur or phasing artifacts. In-game movement is precise with instantaneous reaction to control inputs. It seems counterintuitive to pair a $350 monitor with a $1,600 video card, but the U27G4XM qualifies as a competitor’s tool. It’s a frag master for sure.

The dual-refresh feature was seamless in operation once I set it up in the Nvidia Control Panel. I had to set the options for UHD and FHD just once, 160 and 320 Hz, respectively, then it worked every time. I noted that each mode retained its HDR status, on or off. So, if I was in HDR/160 Hz and switched to 320 Hz, it wouldn’t stay in HDR mode if I hadn’t set it that way previously; no complaint, but just to make you aware. Fortunately, I was fine with running at 160 fps in 4K, so I had no real need for 320 Hz. If you have a slower video card, though, it’s a great alternative to backlight strobing, which usually brings phasing artifacts.

The image is gorgeous in both SDR and HDR. The native color gamut covers over 109% of DCI-P3, so there were always vivid hues to enjoy. When I needed the correct color space for SDR, I could reach for the very accurate sRGB option. The U27G4XM is qualified for color-critical apps.

Work tasks were accomplished with a clear and bright picture that made small fonts and graphical details easy to see. I could sit as close as I liked thanks to the U27G4XM’s 163ppi pixel density. The local dimming worked well on its medium setting. It didn’t increase the peak output, which was nice because then there was no need to change the brightness setting. Rather, it lowered the black level, so contrast was increased with no clipping of detail.

Other things of note were the U27G4XM’s USB ports, three of which are on the right side of the panel. Many budget screens forgo USB ports entirely so to find them here at all is a bonus. I also made use of the gaming aids, aiming point, sniper mode and frame counter. The only thing missing is internal speakers. I had to use headphones to hear game sounds.

Takeaway: The U27G4XM is a superlative value. For $350, you get 4K, 160 Hz, dual-refresh flexibility and a bright, colorful picture. It’s accurate out of the box and calibrates to a high standard. Video processing is top-notch with smooth response and super low input lag. Aside from the OSD buttons and the stand wobble, I have no complaints.

To compare the U27G4XM’s performance, I’ve rounded up dual- and single-refresh 4K 27-inch monitors. The dual models are Titan Army’s P2712V, Acer’s XB273K V5, and ViewSonic’s VX2730D-4K. Single-mode displays include TCL’s 27R94 and Gigabyte’s GS27U.

Pixel Response and Input Lag

Click here to read up on our pixel response and input lag testing procedures.

The monitors in the response time chart are different because it’s unfair to compare LCDs and OLEDs in this test. OLED’s black-to-white transition is much faster, which is why they are smoother at lower refresh rates. On planet LCD, the XB273U F5, a G-Sync Pulsar monitor, shares the speed crown with the ViewSonic VX2730D-4K in its 288 Hz FHD mode. The U27G4XM is a bit behind at 3.58 and 3.74 ms, respectively. Doubling the refresh rate does not halve the response time. This is with the overdrive set to medium, which is the smoothest option that doesn’t have ghosting artifacts.

In the lag test, the U27G4XM takes the win at 320 Hz with a 14ms average of 25 mouse clicks. At 160 Hz, it’s 16.5ms, which is faster than nearly every other screen, including two that are running at 320Hz. So, if you can run in 4K, you’ll have one of the quickest examples available.

Test Takeaway: The U27G4XM has an average panel response for a gaming LCD with an overdrive that removes most motion blur. It’s one of the quickest in my lag test with 14ms at 320 Hz and 16.5ms at 160 Hz. That puts it above all the other 27-inch 4K LCDs I’ve tested except for the ViewSonic VX2730D-4K at 288 Hz. It is certainly the quickest 4K monitor you can buy for $350.

Viewing Angles

The U27G4XM’s off-axis image quality is a little better than most of the IPS panels I’ve photographed. The side view has a slight red tint but no change to brightness or gamma. The top view is also a bit red with reduced brightness and gamma. This is a very shareable monitor.

Screen Uniformity

To learn how we measure screen uniformity, click here.

It’s safe to say that IPS glow is a thing of the past. Today’s panels, like the U27G4XM, show excellent uniformity with no visible issues whatsoever. My sample had no problems in any part of the screen and was uniform in all field patterns, color and neutral.

Uncalibrated – Maximum Backlight Level

The U27G4XM has more than enough light output for any indoor or outdoor environment. With nearly 500 nits peak available, it could be used at a location shoot or turned down to 50 nits for dark room gameplay. The panel’s native contrast is 923.3:1, a bit below the IPS average of 1,000:1. With local dimming set to medium, it delivers around 1,600:1 for SDR content with no clipping in shadow or highlight areas.

After Calibration to 200 nits

Calibration bumps the contrast up to 989.2:1, a slight improvement. With local dimming on medium, it’s around 1,600:1. If you set it to strong, the backlight is shut off, making measurements impossible. ANSI contrast stays relatively consistent at 922.1:1, which is average for IPS panels with either full-array or edge backlights.

Test Takeaway: The U27G4XM offers effective local dimming for SDR content, which sets it apart from some other screens that only dim for HDR. It has nearly 500 nits peak available, making it good for brightly lit environments. Native contrast is just below 1,000:1, and dynamic contrast is 1,600:1 with local dimming on medium. Image depth and texture are exemplary at this price point.

The U27G4XM ships in its Standard picture mode. In the OSD’s parlance, that’s the Standard Game Mode and Standard Eco Adjustment. There are gamut selections available and accuracy is high both before and after calibration.

Grayscale and Gamma Tracking

Our grayscale and gamma tests use Calman calibration software from Portrait Displays. We describe our grayscale and gamma tests in detail here.

The U27G4XM’s default grayscale is a tad cool, but errors barely crack the 3dE threshold, the point where they become visible. Most are below the line, so this monitor can be enjoyed right out of the box. Gamma is right on the 2.2 reference line as well, with no visible issues.

Calibration takes grayscale tracking down to a pro-level 0.42dE. It doesn’t get much better than that. Gamma gets a shade light from 50-90%, but the change is barely visible in actual content. This is excellent performance.

The sRGB gamut mode cannot be calibrated, but it has visually perfect grayscale tracking and slightly light gamma that closely tracks the 2.2 reference. It is suitable for color-critical tasks.

Comparisons

The top three screens, including the U27G4XM, are visually identical in the grayscale test. 2.40dE is a solid result. After calibration, there is no visible difference among the monitors. The U27G4XM’s 0.42dE is a standout result. In the gamma test, the range of values is fairly tight at 0.11 from smallest to largest. Overall tracking is a tad light with a 3.18% deviation representing an actual value of 2.13.

Color Gamut Accuracy

Our color gamut and volume testing use Portrait Displays’ Calman software. For details on our color gamut testing and volume calculations, click here.

The U27G4XM is a very colorful monitor with extra punch across the entire gamut triangle. The default is close to perfect with slight oversaturation and hue errors in red and green. The points track linearly, so there is no loss of detail in any part of the image. Calibration only makes a slight difference that will be hard to see in a before-and-after comparison. But it’s worth doing for the improvement in grayscale tracking. The sRGB mode is better than many pro monitors I’ve tested with an average error of just 0.80dE.

Comparisons

As impressive as the U27G4XM’s accuracy is, it is competing with some equally precise displays. 2.27dE is a great score, but others score better. Is that a difference worth paying for? Not in my opinion, especially when you consider gamut volume, which is the U27G4XM’s main advantage. Amazingly, it does not have a Quantum Dot layer, but it does a great impression of that tech with over 109% coverage of DCI-P3. You will see that in the brightest content where primary colors dominate. There is a good deal of extra red, green, and blue. The sRGB result of 97.93% is nearly ideal and qualifies the U27G4XM for critical tasks.

Test Takeaway: The U27G4XM can be enjoyed without calibration, but a few tweaks take it to reference levels. Gamma is a touch light, but color is exemplary and richly saturated. It has more coverage than the competition, which is a difference that can easily be seen. The sRGB mode is very precise with nearly perfect color and grayscale.

Our HDR benchmarking uses Portrait Displays’ Calman software. To learn about our HDR testing, see our breakdown of how we test PC monitors.

Mini LED displays like the U27G4XM are great for HDR content thanks to their bright backlights and full array zone dimming (FALD). This monitor is rated for VESA DisplayHDR 1000, which is something rarely seen in the OLED category. The signal switch is automatic, and you get four additional picture modes.

HDR Brightness and Contrast

It’s easy to identify which screens are Mini LED in the first chart above. The U27G4XM exceeds its HDR1000 rating, reaching a peak of 1,107 nits. I measured that from a 25% window pattern, and it is extremely bright. Only the TCL is brighter. Local dimming can be used to make the contrast ratio unmeasurable at its highest setting. On medium, the ratio is 13,061.4:1, which is excellent for an IPS panel. I noted that different local dimming settings did not change the peak value, only the black level.

Grayscale, EOTF and Color

In the HDR grayscale test, the U27G4XM is slightly warm in tone from 70% brightness and higher. The error is hard to spot in content, but it would be nice to have RGB sliders available. Of the four HDR modes, Display HDR delivers the best EOTF with values a little below the reference until 60%, where it goes a bit light. These are small variations that will not negatively impact the image. The tone map transition is at 75%, which is correct for the measured white and black levels.

In the color test, the U27G4XM’s large gamut is used to full effect with general oversaturation in all colors. This gives HDR content some extra punch that isn’t strictly accurate, but it is pleasing. The BT.2020 test shows the same response with color running out at 90% red, 80% green and 95% blue. In both charts, hue targets are on point for all six colors.

Test Takeaway: The U27G4XM is a superb HDR display with bright highlights and deep shadows. The Mini LED backlight effectively increases contrast to over 13,000:1 with no penalty. Color is pleasingly oversaturated with vivid hues that deliver great impact to game and video content.

With OLED commanding the premium market, it has driven down the prices of other premium technologies, namely 4K and Mini LED. It is now possible to buy a 27-inch 4K IPS monitor with wide-gamut color, 160 Hz, premium video processing, accurate imaging, and high brightness, and that is a clear sign of progress. The U27G4XM exemplifies that design goal for $350 and offers performance we’d have paid over $1,000 for just a few years ago. And did I mention the Mini LED backlight with 1,152 dimming zones? Yeah, it has that too. For perspective, Acer’s X27 from 2018 had 384 dimming zones, 4K, and 144 Hz for an eye-watering $2,000. Check out that review here if you’re curious.

The AOC U27G4XM is better than that Acer in every way. It has 1,152 dimming zones. It has 109% coverage of DCI-P3 color. It has 160 Hz and a 320 Hz FHD mode. It has lower input lag and better panel response – and it’s $350. That’s what eight years of progress looks like. My only complaints are that the OSD is controlled by buttons instead of a joystick, and the stand is secure but a little wobbly. But performance and image-wise, there are no flaws. For the money, I can’t fault it at all. It games with the very best and provides a bright, colorful, and accurate picture for work and play alike.

If you’re looking for an affordable 4K monitor that pairs well with budget and premium video cards alike, the AOC U27G4XM is well worth checking out.

If you ever travel with your laptop, want to game on a console in places where you don't have access to a TV, or just want a second (or third) screen for your desk, a portable monitor is a must-have. And with many screens at all-time lows, veering into impulse-buy territory (this 15-inch model is incredibly $39), there's never been a better time to pick one up.

But how do you know what to buy when there are dozens of brands (especially on the low end) that you've probably never heard of (I haven't, and I've covered tech for 20 years)? Below are a few quick portable monitor shopping tips, followed by four of our favorite current deals.

• LCD, IPS, or OLED? OLED is the best in terms of color saturation and deep blacks, but it costs much more. IPS has better viewing angles than lesser screen technologies, and is becoming the standard even on budget screens. So you should stick to IPS or OLED at this point.
• Get a monitor with a kickstand. Most portable monitors still have floppy folding covers that double as stands. I've had a screen with one for years and it's awful. A rigid kickstand that's attached to the back and swings out will make you want to use your monitor more often and in more places. All of our deal picks below have kickstands.
• Pay attention to brightness. This spec is often buried on product pages, but it matters a lot, especially if you use the monitor in bright spaces. If using it with your laptop, try and get something that is close to the brightness of that screen. You don't want a washed-out second display.
• Get a cover or sleeve. Since these screens have a kickstand, they likely don't come with a protective cover. But you'll certainly one something to at least protect the screen while traveling. So budget in some extra money to protect your second-screen investment.

Productivity pick: Veout VE-1 16-inch portable monitor

The VE-1 isn't the cheapest deal of this bunch, but I'd argue it's the biggest bargain. It's a little larger than most, thanks to its 16:10 display, which also gives it more pixels for getting work done. It's also rated to 300 nits of brightness and is slim and light for travel. It also comes in different colors for a few dollars more. I like this deal so much that I bought one in late 2024 to replace my aging portable monitor from 2018.

Better for movies and games: Arzopa A1 15.6-inch portable monitor

This glossy FHD model is better for movie watching and games, as it's 16:9 and has a glossy screen. I couldn't find a brightness spec for the A1, but most of the over 1,100 reviews on Amazon seem to be happy with its brightness. It's also light at just 1.6 pounds.

The sub-$40 budget king: WGK W156F1

This screen has a few things going for it, other than its shockingly low price. It has a kickstand and VESA mounts so you can attach it to an arm. It also sports a matte screen, which is better for work and for use under bright lights. Don't believe the spurious claims of HDR and surround sound from the tiny speakers. But for the price, this portable screen is a steal.

The OLED champ: Innocn 15A1F

Yes, the Innocn 15K1F is more than $100 more expensive than some other deals here. But it's also OLED, for deep blacks and vibrant colors, with a rated 400-nits of brightness that puts it ahead of most portable monitor competition.

If you're a photo or video editor on the go or you just want a screen that will look good next to your laptop's OLED display, which also doesn't cost a lot, this is one of the best options we've seen so far this Prime Day. The main downside seems to be that this model lacks a kickstand, so you'll have to use the included wrap-around sleeve as a stand, and those tend to be fiddly or flimsy (and sometimes both).

OLED panels are quickly becoming a must-have item for desktop PCs. Most of us were introduced to the panel technology in smartphones, and it’s become increasingly popular on laptops. For desktop gamers seeking an immediate visual upgrade, OLED is the way to go, and fortunately, Prime Day is proving to be a great time to take the plunge. From massive DQHD panels on the Samsung Odyssey OLED G9 (G93SC) to dual-mode offerings like the LG 27GX790B-B, we have you covered.

Here are the best OLED gaming monitors that we’ve come across so far:

• Check out all the best monitor deals for Prime Day

34-inch Ultrawide OLED Gaming Monitors

The Alienware 34 QD-OLED was the first mainstream QD-OLED monitor, and the updated version, sporting a newer QD-OLED panel and a faster 240Hz refresh rate, is on sale at its lowest price ever on Prime Day. It can now be had for $629.99, or 21% off its list price of $799.99.

We reviewed this model, the AW3425DW, last year and gave it immense praise. It excelled with incredibly accurate color, incredible black levels, and class-leading input lag. It also boasted a color error of only 1.33 based on our testing.

Alienware’s take on this panel has a few unique goodies, as well. It comes with a three-year warranty that covers burn-in, as well as built-in panel-saving features like pixel shifting. This model uses a newer QD-OLED panel that addresses some of the color fringing issues on earlier QD-OLED panels.

32-inch 4K OLED Gaming Monitors

The Samsung Odyssey OLED G8 (G80SD) hits the sweet spot for gaming monitors: it has a 32-inch screen, which is ideal for its 4K resolution (granted, while you'll find 4K in smaller 27-inch panels, 32-inch models are more popular).

You, of course, get a brilliant Samsung QD-OLED panel, which is known more for its rich colors and deep blacks than for extreme brightness. However, the G80SD does stick out like a sore thumb compared to most OLED gaming monitors because it has a matte, anti-glare coating on the panel instead of a glossy finish.

With that said, the G80SD offers a 240 Hz refresh rate at native resolution, is Nvidia G-Sync and AMD FreeSync Premium Pro-certified, and has a 0.03 ms response time. It includes two 10-watt speakers, Bluetooth audio support, DisplayPort 1.4, and HDMI 2.1 ports. You can even turn the G80SD into a multimedia hub thanks to its Smart TV integration with streaming apps and the Samsung Gaming Hub.

Right now, the G80SD is available for $657.77, 47% discount off its list price.

27-inch OLED Gaming Monitors

LG is a leading OLED panel supplier among high-refresh-rate gaming monitors (including some of its primary competitors in the monitor space). They’ve incorporated these panels into their gaming monitor lineup, including the 27GX790B-B. Originally priced at $999, it’s now available for $300 off for Amazon Prime Day, making it a great deal at just $684.99.

The LG 27GX790B-B features an RGB Tandem OLED panel, a 2560 x 1440 (QHD) resolution, and a native refresh rate of 540 Hz. However, if you’re an eSports enthusiast and willing to compromise on resolution to 720p, you can increase the refresh rate to an astonishing 720 Hz. This monitor is designed for gamers with powerful graphics cards capable of delivering over 700 FPS and who are comfortable with 720p resolution.

Asus is also a big player in the gaming monitor market, and it makes that point very clear with the XG27AQDMGR. Being that this is an "XG" monitor, it does away with some of the frills of its more premium siblings to reach a lower price point while still sporting a QD-OLED panel. You can now grab one for just $449 during Amazon Prime Day.

That price gets you a 27-inch 1440p panel with a 240 Hz refresh rate. And who makes that panel, you might ask? Well, LG, of course. The monitor still offers DisplayPort 2.1 despite its lower standing in Asus' monitor rankings, and includes the company's Neo Proximity Sensor to dim the display when you're not sitting in front of it (which goes a long way toward extending panel longevity).

LG Display (LGD) is the arm of LG that manufactures monitor and TV panels for its parent firm, as well as a great deal of other players including Apple, Dell, Sony, and Asus among many others. The company has just announced that its large-format OLED panels earned an Intertek certification for "perfect" color and brightness accuracy under ambient lighting up to 500 lux.

Large-format panels are those going into TVs, generally meaning size 48" or larger. We're taking LG Display at its word, as the press release states the certification means the TVs "accurately reproduce both color and brightness regardless of viewing conditions or content." 500 lux of ambient is actually a pretty demanding viewing environment for a TV, as it's roughly the equivalent to a well-lit office, conference room, or kitchen work surface.

LGD says the certification validates the OLED panels in question for "100% color accuracy" and "100% brightness accuracy," remarking that Intertek used multiple test patterns, and that the panels maintained both accurate color and consistent brightness with all of them. The text also notes the panels are "color cross-talk free," an impressive feat if true. Broadly speaking, OLED panels generally don't bleed light into dark areas, but color contamination in adjacent areas is a real problem thanks to subpixel cross-talk. That's actually a very tricky problem to solve (especially for tandem panels), and it's an impressive feat if LGD truly managed to kill it altogether.

Intertek is a a pretty large UK-based technology and certification company (accredited with ISO/IEC 17025), but there aren't details on the test processes it used. It's worth noting there's no standardized certification process for TV panels to begin with, unlike the monitor-specific DisplayHDR and its strict, OLED-specific True Black variant. LGD has worked with Intertek for many years, and the test results tend to include at least some actual figures.

I’ve been reviewing video tech long enough to remember the advent of 4K displays. In 2013, my first experience was with an Asus PQ321Q. It cost around $3,500, delivered 3840x2160 pixels at 60 Hz, and only worked with a handful of graphics cards that had a DisplayPort 1.2 output.

As prices dropped and choices multiplied, I saw that one of the most common searches on Tom’s Hardware was “budget 4K”. Even though you still need a powerful video card to game at 8.3 megapixels, most users want that high pixel density on their desktops.

The good news is that 4K monitors are no longer $3,500. The ViewSonic VX2730D-4K I’m reviewing here isn’t even $350. It’s $280 and works with many video cards. And it runs at 144 Hz with a dual-mode switch that lets you reach 288 Hz at 1080p resolution. And you get wide-gamut color and HDR on a 27-inch IPS panel with high contrast and high performance. Let’s take a look.

ViewSonic VX2730D-4K Specs

The VX2730D-4K has an impressive feature set wrapped up in an IPS panel that delivers an impressive 1,500:1 contrast ratio. That’s claimed by ViewSonic and verified by me. In fact, I measured over 1,600:1 after calibration, which isn’t necessary because it’s nearly pro-level accurate out of the box. There’s plenty of color coverage too, over 98% of DCI-P3. It also supports HDR10 signals, and there I found a couple of issues that I’ll get into later.

A 144 Hz refresh rate anchors gaming performance at the full 3840x2160 pixels. You can run that signal over DisplayPort or the two HDMI 2.1 inputs. A dual-mode switch changes the resolution to FHD 1920x1080 and 288 Hz. In both cases, you get G-Sync with Nvidia certification and FreeSync Premium. It’ll also do VRR with consoles. There’s a three-level overdrive to smooth out motion blur, and you get MPRT backlight strobing to use when speeds drop below 120fps.

A few unimportant things have been sacrificed on the altar of value. There’s no LED lighting, nor are there USB ports. But you do get internal speakers and a 3.5mm headphone jack. A decent stand and cable bundle come in the box as well. The VX2730D-4K is more than prepared to take on your favorite games, be they twitchy shooters or lavish adventures.

Assembly and Accessories

The VX2730D-4K comes in the cardboard version of a plain brown wrapper with nothing but the words “ViewSonic Gaming” to signal the intent of what’s inside. Crumbly foam disgorges the three main bits, panel, upright, and base, which assemble without tools. Cables are DisplayPort and IEC for the internal power supply.

Product 360

The VX2730D-4K’s styling is minimalist industrial with nothing in front but the screen and its effective anti-glare coating, a ViewSonic logo, and a thin flush bezel. The IPS variant is proclaimed as “Super Clear,” which refers to its higher-than-average contrast. More on that later.

The stand is solid and stable and includes a 4.7-inch height range, 90-degree portrait mode and 5/20 degrees tilt. There is no mechanical swivel, but the metal plate base slides easily on the desktop if you want to turn the panel to either side. The package has decent heft and is very solid in operation. Build quality is well above the norm for a budget display.

In the back, there is purposeful grillwork that provides cooling airflow to the hardworking internals. A larger ViewSonic logo lets others know where your monitor comes from. And there’s a tiny OSD joystick reachable from the front bottom right that controls all functions. The side view shows a relatively slim panel with a component bulge. There’s a small cable hook on the back of the stand.

There are three video inputs in total, one DisplayPort 1.4 and two HDMI 2.1. All support 4K at 144 Hz and FHD at 288 Hz with Adaptive-Sync and HDR. You also get a 3.5mm headphone jack should you wish to forgo the internal speakers, which play politely in the upper mid frequency band.

OSD Features

The VX2730D-4K’s OSD is operated by a joystick, which I found to be a bit different than others. You’d expect that pressing it would bring up the menu, but instead, it’s the dual-mode switch so the screen goes blank for a few seconds, then changes resolutions and refresh rates. There’s no provision to change this, but the dual-mode switch is super quick and convenient.

There are nine picture modes aimed at different game types and uses. Standard is the default and best choice. It’s within a whisker of perfect; the VX2730D-4K does not require calibration. But tweaks are available in the Color Adjust menu where you can change the color temp, adjust saturation and hue and panel luminance. HDR is simply Auto or Off, there are no adjustments there. The sRGB choice in the color temp menu does not change the gamut size, so there is in effect, no sRGB picture mode. You get full color all the time, covering just over 98% of DCI-P3.

You can switch resolution/refresh modes in the OSD using the Dual-Mode field if you’d rather. Like any dual-refresh monitor, you must set up the refresh rates in the Nvidia Control Panel once initially before you can toggle back and forth.

There are three overdrive levels, of which Ultra Fast is the smoothest. I saw no artifacts on any setting. It is reasonably effective, but 144 Hz still has some blur. In the Setup menu, you can turn off Adaptive-Sync in favor of MPRT, which is a backlight strobe. At 144 Hz, the phasing artifact is severe enough that I couldn’t use it. It’s better at 288 Hz where you can only see it slightly. Adaptive-Sync, along with a video card that can maintain max frame rates is the best option. The VX2730D-4K includes PIP and PBP, which is called Multi-Picture. It allows the viewing of two video sources at once.

ViewSonic VX2730D-4K Calibration Settings

The VX2730D-4K measured extremely well out of the box in its Standard picture mode. Grayscale, gamma and gamut tracking were without visual flaws. I found a tiny improvement with a couple of changes to the RGB sliders in the color temp menu. I noted that though there is a choice labeled sRGB, it is not a color space selector. You will see the full native gamut in all scenarios, covering just over 98% of DCI-P3. My recommended SDR settings are below. In HDR mode, there are no options and I noted some issues, which you can read about on page five.

Gaming and Hands-on

The VX2730D-4K’s gameplay experience was excellent in every important way. It is a seriously quick monitor with extremely low input lag on par with many premium screens. Movement and aiming are very precise. Motion blur is well below the level of distraction, even at a relatively pedestrian 144fps when playing in 4K mode. Detail is tack-sharp thanks to that 163ppi pixel density. The panel’s high contrast and saturated color made fine textures pop in both the foreground and the background.

The dual-mode switch worked perfectly once I had set up both resolutions in the Nvidia Control Panel. I found I could switch when paused in Doom Eternal without exiting to the desktop. Playing in FHD/288 Hz mode showed even less motion blur. There is measurably less input lag, but I could not perceive the difference of just 3.1ms. Ultimately, I preferred the sharper detail of 4K even though the frame rate was lower. The overdrive is good enough to keep moving objects sharp, so I could aim precisely at a distance. Lobbing grenades across the icy arena was child’s play as they almost always fell on target.

The only flaw I found was in the VX2730D-4K’s HDR presentation. There is a blue cast to the image, and it is less bright than SDR. You’ll see this confirmed in the tests on page five. The color saturation is there but I ultimately preferred playing in SDR mode because it had more impact.

I’ve noted in the past that dual-mode monitors create a compromise where you get high frame rates but with a sacrifice in resolution. FHD was once a gold standard, but when compared to 27-inch QHD or UHD, it looks soft. There’s no getting around acquired perceptions and after reviewing almost 500 monitors in the past 13 years, I have a few. That said, 27 inches is tolerable for FHD. I can see its appeal to competition gamers who prize response and frame rates above all. The VX2730D-4K is a worthy gaming display for players of all skill levels.

For everyday use, the VX2730D-4K’s high pixel density and accurate color is a real boon. It’s ready to rock out of the box, no calibration needed. I tweaked it to a little higher standard but that’s more to satisfy ego than anything else. It’s colorful and bright and extremely sharp. It has about 60% more contrast than the average IPS panel and that’s a clearly visible difference. The image is cleaner and more textural, almost on the level of a good VA screen. The only thing I missed was an sRGB mode. There’s an sRGB label in the color temp menu, but it doesn’t change the gamut size. You get full DCI-P3 color for all content.

Takeaway: The VX2730D-4K is an extremely capable monitor with just a couple of flaws. HDR doesn’t look any better than SDR thanks to lower brightness and incorrect grayscale tracking. But SDR content is rendered with nearly perfect color accuracy and excellent contrast thanks to low black levels. Gaming is addictive thanks to extremely low input lag and a smooth overdrive. Flaws aside, the VX2730D-4K is a 4K display for $280. That’s about all you actually need to know.

To compare the VX2730D-4K’s performance, I’ve included Alienware’s AW2725QF, Acer’s XB273K, Titan Army’s P2712V, Gigabyte’s GS27U, and Asus’ XG27UCS. The Asus and Alienware monitors are dual-refresh, while the others make do with a single refresh rate.

Pixel Response and Input Lag

Click here to read up on our pixel response and input lag testing procedures.

I’ve only collected data on six LCDs using the Nvidia LDAT test kit, so there are different displays shown in the panel response test chart. Of note is the KTC H27P3, which is a dual-mode, 5K@60 Hz/2K@120 Hz screen. There is almost no difference in response there, but the VX2730D-4K differs by 1.1ms between 288 and 144 Hz. 288 is also where you can actually use the backlight strobe if you want. I tried it at 144 Hz/4K, and it had too much phasing to be viable. The VX2730D-4K at 288 Hz also matched Acer’s excellent G-Sync Pulsar-equipped XB273U F5 at 2.4ms. At 144 Hz, the ViewSonic is good but not great. You can see some blur, even with the overdrive maxed out.

The VX2730D-4K’s dual-mode switch is the path to super quick input lag. It’s the quickest LCD I’ve tested in a while, with just 14.2ms of total delay when averaged over 25 mouse clicks. It’s also quick at 144 Hz, where it beats the 320 Hz Titan Army P2712V. This is excellent performance.

Test Takeaway: The VX2730D-4K shows some motion blur at 144 Hz, but no more than any competitor. It is much smoother at 288 Hz and FHD resolution. The overdrive works well on its quickest setting with no ghosting artifacts visible. The MPRT backlight strobe can only be used effectively in the 288 Hz/FHD mode. It has too much phasing at 144 Hz. Overall, the VX2730D-4K’s video processing is excellent, especially given its low selling price.

Viewing Angles

The VX2730D-4K has off-axis image quality that’s typical of the newest IPS panels. You can see a red tint in both the 45-degree horizontal and vertical planes. In the side view, light output and gamma remain constant. From overhead, brightness goes down by around 30% with a significant gamma reduction resulting in a washed-out image.

Screen Uniformity

To learn how we measure screen uniformity, click here.

The VX2730D-4K’s 6.29% score in my uniformity test is better than I’d expect for a budget display. Remember that we’re talking about 4K at 144 Hz for $280 here. There are no visible hotspots, nor is there bleed or glow.

Uncalibrated – Maximum Backlight Level

The VX2730D-4K is firmly in the “not super bright but bright enough” category. For indoor use, 300 nits is plenty, and you’ll be more comfortable at 180-200 nits peak. What’s more important is the black level, which is almost 50% below the next screen from Titan Army. The resulting contrast of almost 1,600:1 is a standout among IPS panels. This feat is achieved without any clipping.

After Calibration to 200 nits

Contrast gets a tad higher after calibration, where it tops 1,600:1, well ahead of the P2712V. This is a difference you can see in a side-by-side comparison of actual content. Though a VA or OLED screen will look even better, the VX2730D-4K easily outpaces its direct competitors.

In the ANSI test, the VX2730D-4K stays consistent, even adding 3.7 points to the total. It’s rare for any monitor to be this consistent in my contrast tests. On planet IPS, it doesn’t get much better.

Test Takeaway: The VX2730D-4K has lower-than-average black levels for an IPS monitor, resulting in a contrast ratio of over 1,600:1. That delivers a greater perception of color saturation, depth, and sharpness. Coupled with its 163ppi pixel density, it delivers a supremely clear, detailed image. It isn’t super bright, but for any indoor environment, it has more than enough light output.

The VX2730D-4K comes set to its Standard picture mode, which is accurate enough to be enjoyed without calibration. It’s close enough to spec that there are no visible errors for color, grayscale, or gamma.

Grayscale and Gamma Tracking

Our grayscale and gamma tests use Calman calibration software from Portrait Displays. We describe our grayscale and gamma tests in detail here.

If you look very closely at a grayscale step pattern, you might see a hint of red tint at the 90% brightness step. But more than likely, you won’t see anything wrong. And you certainly won’t see any problems in actual content. Gamma is also nearly perfect with close tracking to the 2.2 spec over the entire luminance range.

By calibrating the RGB sliders, which only required one click changes to red and green, I got all grayscale errors below 1dE. That’s pro-level accuracy. Gamma was mostly unchanged but the 70-90% region got a tad darker. This was not a factor in actual content. I noted a slight increase in overall contrast, too so it’s worth making the adjustments.

Though the VX2730D-4K includes an sRGB option in the color temp menu, it does not change the gamut volume, so there is no actual sRGB mode.

Comparisons

The VX2730D-4K’s out-of-box grayscale error of 2.14dE is impressive but not unprecedented. The Asus and Titan Army screens measure a bit better. But the top three monitors are without visible errors, so it’s a wash. After calibration, all the screens look the same, with no visible grayscale issues.

In the gamma test, the VX2730D-4K’s slight rise at 70-90% makes its value range a tad less tight than the rest. The 1.82% deviation represents an actual value of 2.24. There are no visible gamma issues with any of the monitors. They all exhibit excellent performance.

Color Gamut Accuracy

Our color gamut and volume testing use Portrait Displays’ Calman software. For details on our color gamut testing and volume calculations, click here.

Though you won’t see any color errors in content, the VX2730D-4K has slight hue anomalies in the secondary colors, magenta, cyan, and yellow when put under the colorimeter. Red is also a tad oversaturated throughout. Calibration fixes those bits neatly and takes the average error to an impressive 0.99dE. It doesn’t get much better than that.

Comparisons

All the monitors have impressively accurate color gamuts, but the VX2730D-4K is the best at 0.99dE. It’s rare for any monitor, even a professional screen, to get under 1dE for a 31-point average test. This is exceptional performance. In the volume test, the ViewSonic nearly covers the full DCI-P3 gamut, coming up a tad short only in the green primary. My only complaint is that there is no sRGB mode. You’ll have to perform color-critical tasks in P3, which is more than accurate enough. sRGB is useful for photography and web graphics so it would make a good addition for a future firmware update.

Test Takeaway: The VX2730D-4K has better than average out-of-box color with no need for calibration in its Standard picture mode. It covers almost 100% of DCI-P3, 98.38%, coming up a tad short in the green primary. It calibrates to a very high standard that only some pro monitors can match. The only thing missing is an sRGB mode. There is no provision for gamut selection here.

Our HDR benchmarking uses Portrait Displays’ Calman software. To learn about our HDR testing, see our breakdown of how we test PC monitors.

The VX2730D-4K supports HDR10 signals with an automatic switch if HDR is set to Auto in the OSD. I noted some issues which I’ll detail below.

HDR Brightness and Contrast

The VX2730D-4K has an edge LED backlight with no dimming available for HDR so I expected that it would match output levels between SDR and HDR. I could only get to 207 nits with no provision for improvement. I checked full field and window patterns and got the same result. Black levels are about the same as they are in SDR with the backlight maxed, so contrast drops to 1,080.6:1. This gives HDR content the same appearance as SDR with no additional depth or impact.

Grayscale, EOTF and Color

HDR grayscale tracking is decidedly blue, and I didn’t need the meter to tell me there was an error. I could see it in step patterns and full fields. This further flattens the image to where it has less impact than its SDR counterpart. The EOTF runs a bit dark, below the reference line, but stays consistent enough to keep all detail visible.

In the gamut test, you can see the effect of the skewed grayscale tracking. All colors are pulled off their hue and saturation targets. HDR is colorful thanks to the VX2730D-4K’s large gamut, but it is not impactful due to the errors I noted. In the BT.2020, color runs out at 90% red, 75% green and 95% blue.

Test Takeaway: The VX2730D-4K’s HDR presentation is lackluster at best. Brightness is reduced by around 30% from maximum and contrast goes down as well. Grayscale errors result in a flat image with no more impact than its SDR counterpart. While the HDR mode is usable, it doesn’t provide any advantages over SDR.

4K monitors have long been in the realm of the exotic, but they’ve come very far from their $3,500 roots. That you can buy a 27-inch UHD screen with 144 Hz, Adaptive-Sync and extended color for $280 is a clear indication of progress to the positive.

The ViewSonic VX2730D-4K delivers tremendous performance and quality for the price. Not only is it 4K at 144 Hz, but it is also Full HD at 288 Hz. Gaming is super quick and smooth thanks to excellent video processing and a convenient resolution switch, and I was even able to toggle it without leaving the game, which is a first in my experience. The overdrive removes nearly all motion blur, and gameplay is precise and satisfying at either resolution. There’s MPRT backlight strobing for smoothness at lower frame rates, but I found it was only usable in the FHD/288 Hz mode.

My only complaint here is with the VX2730D-4K’s HDR presentation. It is less bright than SDR by around 30% and its bluish grayscale is visible in content. Though the monitor supports HDR10 signals, it doesn’t give them much love. I found that after some time, I preferred playing everything in SDR mode.

Minor issue aside, the ViewSonic VX2730D-4K is a 4K gaming monitor for $280. That forgives a lot and at this point in time, it has no serious competition. If you’re looking for a budget monitor that’s speedy, responsive and colorful, you should definitely check it out.
