Acer Predator X27U W3 review: simple design, but very impressive performance
Table of Contents
The Predator X27U W3 is Acer’s latest 240Hz, 1440p OLED gaming monitor. It comes equipped with the increasingly popular QD-OLED panel technology, delivering a stunning visual experience defined by punchy colors, deep blacks, and impressive visual clarity. It also positions itself as one of the cheaper OLED displays in today’s market, continuing the trend of falling OLED prices.
But how does this powerful OLED monitor perform against the market’s leading rivals? Well, that’s what we’re here to find out. With OLED monitors growing in popularity and prices now finally starting to dip, could the Acer Predator X27U W3 be crowned as one of the best gaming monitors in 2026? That’s exactly what we’re here to answer, putting it through all our usual tests to see how it stacks up against the big names in the monitor space.
- Panel type: QD-OLED
- Resolution: 2560 x 1440
- Refresh rate: 240Hz
- Response time: 0.03 ms
- Panel size: 26.5″
- I/O ports: 2x HDMI 2.1, 1x DP 1.4, 1x 3.5mm audio jack
When it comes to upgrading a monitor, the Acer Predator X27U W3 brings about a really appealing design. As a 1440p, 27-inch, 240Hz screen, it does bring an upgraded quality and feel over most options. Along with a QD-OLED panel that offers a great color gamut, vibrancy, and contrast, it really does make everything look better.
It does, however, not have a great peak brightness and might struggle in brighter places, and doesn’t have the best calibration out of the box. It also lacks a good range of connections beyond the basics, but still, if those aren’t limitations, the price and color gamut do make it an excellent choice.
- Great color gamut coverage
- Fast refresh rate and good resolution
- Decent price, but limited availability
- Plenty of good OLED care settings and warranty coverage
- Needs some calibration and adjustment for best color accuracy
- Doesn’t get high brightness
- Lacking in onboard connectivity
Pricing & availability
Finding a retailer that stocks the monitor takes some scouring of the web. The first indication of the monitor’s existence is on the Acer website, where, when you untick the stock-limiting filters, it shows the monitor’s MSRP of $429.99. That said, you can get it at Costco US for $399.99. While in the UK, it is on its way with an expected release of July 2026 at an MSRP of £399.
Prime Day may have ended, but that hasn't stopped major retailers slashing prices on popular tech hardware. Below, we've listed some of the best deals available today.

Design & specifications
Much like the XB273U F5 model (which we recently reviewed), the packaging on the X27U W3 follows the same principles. As the side opens, it reveals the monitor and everything it comes with. This includes a selection of cables, a disassembled stand, and a stack of booklets on top – with the monitor itself tucked beneath a protective layer. It’s wrapped in protective covers and securely nestled between cardboard for added safety.

Assembling the stand is rather quick and simple, with a screw holding the bottom in place and a quick click-in joint for both the plate and the monitor itself. It then provides a great deal of adjustability, with full 180-degree rotation, a lot of height movement, and pivot.

The back of the monitor keeps things very simple, with a few basic details around the inner edge and the Predator logo above. On the bottom edge, there is a protrusion that houses the OSD joystick and power button on the left and a Kensington lock port on the right. Then, on either side of the stand, there are the ports, which on this monitor are very limited. On the right, there are just three video ports (2x HDMI and 1x DP) and a 3.5mm audio jack. On the left is just the power input.

OSD, features, settings, & warranty
Firing up the monitor and accessing the OSD via the joystick around the back, you’re prompted by the quick-access menu that provides some useful settings, including color mode, brightness, input, and entry into the rest of the menu. Entering the main menu, all the usual suspects can be found, including more advanced color settings, brightness options, full OSD control, picture modes and full OLED Care. Like most modern gaming displays, there’s also a gaming menu which allows you to toggle the variable refresh rate (G-Sync) and pull up a refresh rate counter.
As for the OLED Care, Acer provides image retention refresh, pixel centering, and static image upkeep to protect the panel over the years.

With lots of onboard protection, the OLED panel should last for a while without burn-in – providing excellent colors if it’s calibrated correctly (as we find out in the next section). But if you do have problems, Acer does have a three-year limited warranty on its monitors, including covering OLED burn-in for three years.
Screen testing and performance
After warming the panel up and going over its settings, I put the monitor through its paces in our testing lab. The first thing I noticed was that, when the screen was off, you could see a purple hue – often an indicator of the missing polarizer layer. This, while seemingly obscure, is not a defect.
Color gamut
One of the tests we run is checking how much of the color gamut the display can produce. Measuring out the percentage of the sRGB, Adobe RGB, and DCI-P3 color spectrums that it can cover. For this test, we usually run the out-of-the-box configuration, alongside a calibrated scenario – although that seemingly didn’t make much difference on this display.

| Color space | OOB gamut coverage | OOB gamut volume | Calibrated gamut coverage | Calibrated gamut volume |
|---|---|---|---|---|
| sRGB | 100.00% | 170.00% | 100.00% | 169.40% |
| Adobe RGB | 95.70% | 117.10% | 95.30% | 116.70% |
| DCI-P3 | 99.20% | 120.40% | 99.20% | 120.00% |
For the X27U W3, it pretty much covers both the sRGB and DCI-P3 spectra, with a 100% and 99.2% gamut coverage on those, respectively. While Adobe RGB falls a bit behind, it’s not by much, with a 95.7% coverage. That is still a decent chunk and should provide a good option for color-accurate work if the accuracy is there.
Even when I calibrated the monitor for accuracy, the gamut coverage didn’t improve at all; in fact, the Adobe RGB lost a couple of decimal points. So in fact, it does a great job out of the factory in the color range it can reproduce.
Color accuracy, contrast, & brightness
When it comes to the accuracy of the colors being reproduced on the monitor, that can vary depending on which mode you choose. Changing out the different color modes and testing them individually, here’s how they performed. As a note, I would usually set them all to the same 120 nits brightness, but I could only alter the brightness in the user mode, as the others have theirs locked.
| White point | Black point | Contrast | Average deltaE*00 | Max deltaE*00 | Gamma | Brightness | |
|---|---|---|---|---|---|---|---|
| IDEAL | 6500K | 0 cd/m² | infinity:1 | 0 | 0 | 2.2 | |
| Standard (out-of-the-box) | 6766K | 0 cd/m² | Infinity:1 | 3.24 | 7.51 | 2.24 | 135.2 cd/m² |
| User | 6754K | 0 cd/m² | Infinity:1 | 3.22 | 7.5 | 2.23 | 120.5 cd/m² |
| Eco | 6726K | 0 cd/m² | Infinity:1 | 3.32 | 7.54 | 2.23 | 87.8 cd/m² |
| Graphics | 6406K | 0 cd/m² | Infinity:1 | 3.87 | 8.98 | 2.07 | 178.1 cd/m² |
| HDR | 6839K | 0 cd/m² | Infinity:1 | 1.65 | 2.87 | 2.05 | 222.2 cd/m² |
| Calibrated user | 6522K | 0 cd/m² | Infinity:1 | 0.49 | 4.07 | 2.21 | 119 cd/m² |
As expected, the OLED panel does provide the ideal black point and contrast, thanks to individual LED control and the absence of an LED backlight. Across the various color modes, the white point tended to be higher, with the monitor being warmer than our ideal figures. The results showed that standard, user, eco, and HDR were a few hundred Kelvin warmer. But the graphics and calibrated options do set it to the right level.
For color accuracy, most of the preset modes aren’t ideal for doing color accurate work – which is to be expected. From standard to graphics, they all have an average delta above 3, with the max variance going above 7 or even 8, meaning the colors aren’t being displayed as they should be.
Weirdly enough, HDR mode does bring that closer to ‘proper’ decent levels of just an average of 1.65 and a max of 2.87 at the cost of contrast, which lowers to 2.05. It also provides the highest peak brightness of the lot, as it jumps to 222 cd/m² compared to others sitting well below that.
The monitor does allow for plenty of adjustments, and calibration allowed us to dial in the accuracy to near-perfect. As the white point is right around 6500K, gamma of 2.21, and brightness of 119 candelas. The average delta falls to 0.49, but the max sits still above 4, with just one particular shade of brown 4 points above, with the rest of the spectrum not going above 3.
Panel uniformity
Next up is the uniformity of the panel and how its brightness and color stay the same across the whole screen from the center reference square. Below is a representation of that from a 5 x 5 grid test of just that. The different colors indicate how similar each segment is to the reference square, with green being within the recommended tolerance, yellow being nominal, and red exceeding that.
Generally, the center of the screen is fairly in spec and stays within tolerance, but around the edge, the uniformity starts to falter. Particularly in the corners where it deviates from nominal tolerance. Not quite reaching the same peak brightness as the center, and the colors are quite a bit off in accuracy. Fortunately enough, it is around the corners that you’re less likely to be focused on.
Viewing angles
Another key advantage of OLED panels is their wide viewing angles, typically up to 178°. This means you can still clearly see the content even from off-centre positions. So whether the display is positioned slightly to the side or you’re sharing the screen with multiple people, the image remains consistent without noticeable fading or colour shift.

Gaming performance
Lastly, I tested out the monitor in gaming, noting how it feels to use it, which, right from the get-go, is a great experience. As soon as I set that 240Hz refresh rate, it felt smooth and responsive, with everything being a lot more enjoyable to play. Particularly running Esports titles like CS2, where I could easily track enemies and respond quickly to everything happening on screen.

Plus, with the color accuracy and fantastic contrast, it does provide a very immersive-looking quality to all the games. With lights, weather, and shadows really getting that extra depth to them. Something I certainly don’t see day to day on my IPS panel.
I played CS2 for about an hour, and after switching from a fast IPS panel, the difference was immediately noticeable. Quick peeks around corners and strafing from angle to angle felt buttery smooth – something that’s often the case with OLED panels we’ve tested. You just can’t argue with that near-instant response time; it makes a real difference in games that require rapid reaction times. I play CS2 at a reasonably competitive level, so having that liquid-smooth clarity is a must.
I then fired up Forza, which offers a slightly different kind of fast-moving experience. Again, everything felt incredibly smooth, with no signs of ghosting or screen tearing, largely thanks to Nvidia G-Sync support. Overall, gaming on this monitor felt fantastic. If you haven’t used an OLED panel before, the upgrade really does feel like night and day.
Response rate
After having a play with it, I then used our OSRTT to measure the response time of the monitor. With both vsync on and off, the responsiveness was very good. As the initial response time was between 0.82 and 0.7, with the average complete time taking 1.39 and 1.31. With those producing perceived times of 0.84 and 0.71.
As you can see from the results above, it’s green across the board – essentially meaning its an incredibly fast monitor. This just cements our earlier claims that this display would be perfect for competitive players who want rapid response, vibrant visuals, and excellent clarity.
General performance & productivity
As for everyday and productivity tasks, the Acer Predator X27U W3 is still a fairly decent option depending on your use case. For the likes of color-accurate work, sRGB and DCI-P3 are perfectly fine color spectra to work in, but for AdobeRGB, it does fall behind slightly. Plus, you might need to calibrate and change the settings to get it to the right levels, too.

One of the things with the monitor, though, is that it doesn’t have the highest peak brightness. So if you do have it in a bright room with lights, it might be hard to see, and it even reflects those lights with a purple hue. In my tests, it reached around 192 cd/m², with HDR mode hitting a brightness of 222 cd/m² – so not the brightest, even by OLED standards.
Otherwise, it offers exceptional value for what you get, especially with the increased resolution delivering strong visual fidelity. While it isn’t 4K for those seeking the absolute highest-end option, the 27-inch size feels like a sweet spot for most users. That said, it still doesn’t provide the same level of screen real estate you’d get from larger displays.
- Panel type: QD-OLED
- Resolution: 2560 x 1440
- Refresh rate: 240Hz
- Response time: 0.03 ms
- Panel size: 26.5″
- I/O ports: 2x HDMI 2.1, 1x DP 1.4, 1x 3.5mm audio jack
Conclusion
Overall, the Acer Predator X27U W3 monitor is a great option for a variety of uses. The QD-OLED panel provides great-looking colors and deep blacks with coverage of a wide selection of color spectra. It does need some tweaking to get better accuracy and doesn’t have the brightest output, but it’s great to use. With fast responsiveness and improved quality, the monitor gives great results for a reasonable price.
