Popular Monitor Comparisons
The Acer Predator XB273U GXbmiipruzx is a 27-inch, 240Hz gaming monitor that's well suited to both productivity and gaming. It stands out from its competitors by having a large USB hub and providing enough power over USB-C to charge many laptops while they're operating, so it's a great choice if you regularly connect a laptop. However, it has worse motion handling in VRR than its competitors, so it doesn't work as well if you plan to spend a lot of time gaming. If you prefer monitors with better gaming performance, consider similar monitors like the Gigabyte M27Q X and the LG 27GR83Q-B.

The Acer Predator XB273U GXbmiipruzx and the Acer Nitro XV272U KVbmiiprzx perform similarly. That said, the Predator has a higher refresh rate. Response times and input lag are similar, but the Predator has a wider color gamut, especially with Adobe RGB coverage.
The MSI Optix MAG274QRF-QD and the Acer Predator XB273U GXbmiipruzx are similar monitors, but the Acer has more to recommend. 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.
The Acer Predator XB273U GXbmiipruzx and the ASUS ROG Strix XG27AQ perform 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.
We buy and test more than 30 monitors each year, all of which we purchase ourselves, without cherry-picked units or samples. We put a lot into each unbiased, straight-to-the-point review, and there's a whole process from purchasing to publishing, involving multiple teams and people. We do more than just use the monitor for a week; we use specialized, custom tools to measure various aspects and deliver objective, data-driven results. We also consider multiple factors before making any recommendations, including the monitor's cost, its performance compared to the competition, and whether it's easy to find.
