I copied changes to FriendlyELEC NanoPC-T6 DT and booted 6.12-rc3 with 
your changes on LTS variant of the board.

With my SBC monitor it complained about resolution (10.5" 1366x768px):

rockchip-drm display-subsystem: [drm] *ERROR* vp0 Cluster0-win0 
actual_w[1366] not 4 pixel aligned

And monitor told me "no signal".

/sys/devices/platform/display-subsystem/drm/card1/card1-HDMI-A-1/modes 
lists all resolutions available.

Would be nice to see system going to next EDID resolution in such case. 
1280x720px is 4px aligned.


With my 34" 3440x1440px monitor it shown some output once. In resolution 
close to original one but 16:9 instead of 21:9 one. Anyway monitor 
behaved in "I do not like that signal" way - started blinking, had 
problems with displaying even from my desktop after.


I got a feeling that 1920x1080px monitor landed on my "need to buy" list.
