How to use
Place the monitor on a stable surface or mount it using a compatible VESA arm.

Connect peripherals to the built-in USB hub for convenient access. Adjust the stand height and viewing angle for an ergonomic position.
Usage recommendations
For competitive gaming prioritize the FHD 320 Hz mode and lower in-game graphics settings to achieve the highest frame rates.

Ensure HDMI 2.1 or a high-bandwidth DisplayPort and suitable cables to use high refresh-rate modes reliably.
