Our Verdict
Acer Predator X27U bmiipruzx
Corsair XENEON 27QHD240
The Acer Predator X27U bmiipruzx and the Corsair XENEON 27QHD240 use the same OLED panel, so they have minor differences, and most of the differences come down to features. The Acer gets brighter in SDR, but the HDR brightness between the two is similar. Besides that, the Corsair has a bigger USB hub with more ports, and it supports HDMI 2.1 bandwidth, allowing it to take full advantage of gaming consoles. However, the Acer has a more ergonomic stand, making it easier to adjust.
