Hi @louis_d ,
Regarding your issue, we would like to confirm the following points:
- Try replacing the cable to ensure the cable specifications meet the requirements of both the monitor and the main unit.
- Make sure the monitor's refresh rate/resolution settings match the output frame rate of the main unit.
- If you have HDR enabled, try disabling HDR to see if it resolves the issue.
- Since the issue disappears when connected to a PC, the problem may lie with the main unit or the HDMI cable. We recommend ensuring that all drivers on the main unit are updated to the latest version.
Thank you for your understanding and cooperation.
Thank you.
