How to use

Place the monitor on a stable surface or mount it using a VESA-compatible arm or bracket. Connect your PC or console using the recommended display input for your desired mode: use native 4K inputs for 3840 x 2160 at up to 160 Hz, or enable the Frame Rate Boost hotkey to switch to 1080p at up to 320 Hz for competitive play. Use the on-screen display (OSD) to adjust brightness, colour settings, and enable DisplayHDR400 as needed. Connect peripherals via the USB Type-C downstream port if supported by your devices.

Recommendations

For competitive gaming, enable the FHD 320 Hz mode with the Frame Rate Boost hotkey and use low-latency display settings. For colour-critical work or immersive single-player gaming, use the native 4K 160 Hz mode and calibrate colours through the OSD or a hardware calibrator. Ensure adequate cooling and avoid prolonged maximum-brightness HDR use to reduce energy consumption and extend panel life.
