The Acer Predator XB273U GXbmiipruzx is a great all-around monitor with excellent gaming performance and plenty of features. It has an overclocked 270Hz refresh rate and exceptionally low input lag that make gaming feel smooth and responsive. It also has an incredible response time and variable refresh rate (VRR) support. It feels solidly built, and it has very good ergonomics so you can set it as you like. It's an IPS monitor, so the contrast ratio is limited, but it's not bad overall, and the monitor has wide viewing angles, making it easy to share content or game with a friend. It also gets very bright, enough to overcome glare in most lighting conditions. While its HDR brightness is only decent, it's on the brighter side for a monitor, and it has one of the widest HDR color gamuts we've tested, along with an exceptional SDR color gamut. It can also display 10-bit color in 1440p at 270Hz by using Display Stream Compression (DSC).

The Acer Predator XB273U GX has an incredible response time at its max refresh rate, resulting in exceptionally clear motion in fast-moving content. We recommend the 'Normal' overdrive setting, as it's the fastest and the amount of overshoot is acceptable. The 'Off' setting has no overshoot, but it's a bit slower, while the 'Extreme' setting has too much overshoot.

The Acer XB273U GX has a native 240Hz refresh rate, which can be overclocked to 270Hz. It supports Adaptive Sync natively, is FreeSync-compatible, and is certified as G-SYNC-compatible. Unfortunately, you can't enable VRR while 'Overclock' is on, meaning the monitor is limited to 240Hz with VRR. Enabling VRR also locks the overdrive setting to 'Normal'. While that's the recommended setting for the max refresh rate, it's not recommended for 60Hz because the overshoot is too noticeable, which could be frustrating if you're playing low frame rate games.

The Acer XB273U GX has a remarkably low input lag. It's a bit higher at 60Hz, but it's still quite low overall. The monitor uses Display Stream Compression (DSC) to achieve its 270Hz refresh rate, allowing it to display a 10-bit signal at 270Hz. However, we don't have the tools to measure input lag over DisplayPort, and the maximum refresh rate at 10 bit over HDMI is only 60Hz, so we can't determine the input lag for 10-bit HDR. We don't expect HDR to have a significant impact on input lag, though.

Differences Between Sizes And Variants

We tested the 27 inch Acer Predator XB273U GXbmiipruzx. It's the only one of this specific model, but there are several similar monitors under the Acer XB3 umbrella. You can see the differences between some of them below.

 Model  Size Panel Type   Refresh Rate Resolution
XB273U GSBMIIPRZX 27" IPS  165Hz  1440p 
 XB273U GXbmiipruzx 27"  IPS  240Hz (270Hz overclocked)  1440p
XB323U GXbmiiphzx  32"  IPS  240Hz   1440p

If you come across a different panel type or your Acer XB273U GX doesn't correspond to our review, let us know and we'll update it. Note that some tests, like gray uniformity, can vary between individual units.

Our unit was manufactured in November 2020, and you can see the label here.

Compared To Other Monitors

The Acer Predator XB273U GXmiipruzx is a great gaming monitor. It has one of the widest HDR color gamuts on any monitor we've tested and is one of the few with full coverage of the Adobe RGB color space. On top of that, it can display a 10-bit signal at 270Hz thanks to DSC, unlike a lot of monitors. However, it's on the pricier side for a 27 inch 1440p monitor.

For more options, see our recommendations for the best 1440p gaming monitors, the best 240Hz monitors, and the best gaming monitors on the market.

Gigabyte M27Q

The Gigabyte M27Q and the Acer Predator XB273U GXbmiipruzx are excellent gaming monitors that stand out due to their exceptionally wide color gamuts. They also both have incredibly fast response times and low input lag. The biggest difference is that the Acer has a higher refresh rate of 270Hz versus the 170Hz on the Gigabyte.

Samsung Odyssey G7 LC32G75T

The Samsung Odyssey G7 LC32G75T and the Acer Predator XB273U GXbmiipruzx are great monitors that offer amazing gaming features; they also use different panels with different advantages. The Samsung is a VA monitor, so it has a higher contrast ratio and narrower viewing angles. It comes in both a 27 inch and 32 inch size. The Acer, on the other hand, has an IPS panel, so its contrast is worse, but it has wide viewing angles. When it comes to gaming, they both have exceptionally fast response times and low input lag.

Dell Alienware AW2721D

The Acer Predator XB273U GXbmiipruzx and the Dell Alienware AW2721D are both great monitors, but the Acer performs a little better overall, especially when it comes to gaming. The Acer has a higher overclockable refresh rate, as well as faster response times at both its max refresh rate and 60Hz. It also has a wider color gamut and better reflection handling, as well as a USB-C port with power delivery and DisplayPort Alt mode.

Gigabyte AORUS FI27Q-X

The Gigabyte AORUS FI27Q-X and the Acer Predator XB273U GXbmiipruzx perform very similarly overall. They both have native 240Hz refresh rates, although the Acer can be overclocked to 270Hz. Both have fantastic response times as well. The Acer, however, is better for HDR gaming because it has a slightly wider color gamut and better color volume. It gets a bit brighter in SDR as well.

Acer Nitro XV272U KVbmiiprzx

The Acer Predator XB273U GXbmiipruzx and the Acer Nitro XV272U KVbmiiprzx perform quite similarly overall. That said, the Predator gets much brighter than the Nitro in SDR, so it can easily overcome glare, and it has a higher refresh rate. Response times and input lag are similar, but the Predator also has a wider color gamut, especially when it comes to Adobe RGB coverage.

MSI Optix MAG274QRF-QD

The MSI Optix MAG274QRF-QD and the Acer Predator XB273U GXbmiipruzx are similar monitors, but the Acer has a bit more to recommend it. They both have exceptional color gamuts, but the MSI lacks an sRGB setting, so colors appear oversaturated. The Acer also has a higher refresh rate, gets brighter in SDR and HDR, and has better accuracy out of the box.

ASUS ROG Strix XG27AQ

The Acer Predator XB273U GXbmiipruzx and the ASUS ROG Strix XG27AQ perform quite similarly. They both have superb response times, although the Acer has a higher refresh rate of 270Hz, versus 170Hz on the ASUS. The Acer gets significantly brighter in SDR and brighter in HDR too, and it has a wider color gamut.

Dell S2721DGF

The Dell S2721DGF and the Acer Predator XB273U GXbmiipruzx both perform well when it comes to gaming, but the Acer has a significantly higher refresh rate at 270Hz, while the Dell maxes out at 165Hz. Still, both have exceptional response times and low input lag. The Acer has a few extra features that the Dell doesn't, like Black Frame Insertion (BFI), built-in speakers, and a USB-C port with power delivery and DisplayPort Alt mode.

LG 27GL850-B

The Acer Predator XB273U GXbmiipruzx is a better monitor overall than the LG 27GL850-B. The Acer has a higher refresh rate and faster response times with less overshoot. It has less of an issue with glare since it gets brighter, and it has a wider color gamut. It also has more ergonomic adjustment options, better text clarity, and more USB ports, including a USB-C port, so it's better suited to productivity.

Dell Alienware AW2521H

The Dell Alienware AW2521H and the Acer Predator XB273U GXbmiipruzx are very different gaming monitors. The Dell is a 25 inch 1080p monitor with a 360Hz refresh rate, aimed at competitive gamers who want the best possible motion clarity. Meanwhile, the Acer is a 27 inch 1440p monitor, so you get a bit of a sharper image and a little more screen space to work with. It still has a high 270Hz refresh rate, however, and both have incredible response times. The Acer also has a wider color gamut in SDR and HDR.
