Hi mingyigoodluck,

Please export DISPLAY=:0 and use “xrandr” to see the mode supported. The 4k@30 mode in your display may be not compatible with our driver.

To see more information in logs about how modes are treated, add this to the ‘Section “Device”’:

Option "ModeDebug"

Then look at “/var/log/Xorg.0.log” after a reboot. Example:

cat /var/log/Xorg.0.log | gawk '/VideoBIOS/,/End of ModePool/'
