How to use
Connect the monitor to your PC, console or laptop using DisplayPort 1.4, HDMI 2.1, or the USB Type-C port with DP Alt Mode if supported by your device. Configure the monitor settings via the on-screen display or DisplayWidget Center to enable preferred refresh rates, adaptive sync and ELMB-SYNC. Use the ergonomic stand to adjust tilt, swivel, pivot and height for a comfortable viewing position. If you plan wall mounting, use the VESA mount and compatible bracket. For best color accuracy, keep factory calibration settings or perform calibration with a colorimeter if required.
Recommendations
Verify that your device’s USB-C port supports DP Alt Mode and sufficient power delivery before relying on Type-C for video and charging. Use DisplayPort 1.4 or HDMI 2.1 for full-resolution, high-refresh connections when DP Alt Mode is not available. Ensure your GPU drivers and monitor firmware are up to date to enable G-SYNC compatibility and optimal performance.
