Hello @PeterPPP

It seems that the resolution is not supported, could you provide the edid information of your screen?

edid-decode < /sys/class/drm/card0-HDMI-A-1/edid

Thank you for your response. I used Custom Resolution Utility on windows to get the following edid infomation

Hello @PeterPPP

It seems that this is a special resolution 1728x2368 which is not supported by current system.
