How to use

Connect the monitor to your graphics source using DisplayPort, HDMI or USB‑C (DP Alt Mode) depending on your device and desired refresh rate. Use the monitor OSD or the ASUS DisplayWidget Center application to select the target refresh rate, enable ELMB SYNC or adaptive sync features, and adjust brightness and color settings. Mount the display on a VESA arm or use the integrated stand with height adjustment to set an ergonomic viewing position.

Recommendations

For the best competitive performance, use a DisplayPort 1.4 connection with a compatible GPU and set the refresh rate to the highest stable value. Enable ELMB SYNC together with VRR when available to reduce ghosting without disabling adaptive sync. When using USB‑C, confirm your source supports DisplayPort Alt Mode to achieve high refresh rates.
