Ok, I have now applied the following patches:
kernel-6.1:
- 4K resolution "hardcoded" in Android 14 images - #4 by xiong.zhang
- DP: fix 1080p cannot work for dp [2/2] · khadas/linux@4a8a65d · GitHub
- drm/bridge: synopsys: dw-hdmi-qp: Check that necessary hdmi clock is … · khadas/linux@cb42b8d · GitHub
u-boot:
I still don"t see any improvement by default.
But, if I tweak the resolution manually to 1920x1080p59.94, then, after a reboot it works.
Is there any additional patch I should apply to make it works by default like on Android 13?
