This 27-inch QHD gaming monitor uses a 10-bit QD-OLED panel and reaches a 500Hz refresh rate with a 0.03ms response time. Uniquely, it can hit the full 500Hz over both its DisplayPort 1.4 (with DSC) and its two HDMI 2.1 inputs, giving you flexibility across PCs and consoles. There is no USB-C video input, so it connects to a desktop GPU rather than charging a laptop over one cable. A USB 3.2 Gen 1 hub (one upstream, two downstream) and a 3.5mm headphone jack handle peripherals and audio.
ASUS’s 27″ 500Hz QD-OLED reaching 500Hz over DisplayPort 1.4 and dual HDMI 2.1, plus a USB 3.2 hub and headphone jack.
