How to use

Place the monitor on a stable desk or attach it to a VESA-compatible arm using the 100 × 100 mm pattern. Connect a source device with HDMI or DisplayPort cable and configure the source output and graphics driver to 3840 × 2160 at 60 Hz for native performance. Use the on-screen display (OSD) menu to enable HDR10 for compatible content and to activate AdaptiveSync if supported by your GPU. Adjust the tilt between -5° and 20° to achieve a comfortable viewing angle.

Recommendations

Use a high-speed HDMI cable or DisplayPort cable for 4K@60Hz and verify your graphics card supports 4K@60Hz and AdaptiveSync. Keep monitor firmware and GPU drivers updated to ensure stable performance and compatibility.
