Use the on-screen menu or the DisplayWidget Center application to calibrate color, adjust refresh rate, enable ELMB SYNC and adaptive sync, and configure gaming AI features. Adjust height and tilt to achieve an ergonomic viewing position and ensure the display is set to native 2560×1440 resolution in your operating system for best image clarity.

Recommendations

For competitive gaming, enable the highest supported refresh rate and ELMB SYNC together with adaptive sync to minimize blur and tearing. For color-critical work, perform a basic calibration using the on-screen settings or a hardware calibrator, and keep brightness at a level appropriate for your ambient lighting to reduce eye strain and preserve color accuracy.
