Edge2 Andorid 14 - Custom Resolutions not showing

Edge2

Hi

If you remove resolution_white.xml, Settings and TvSettings apps doesn’t show all the resolutions and frame-rates eg. 1920x1080p@23.976hz.
The only show standard resolutions and not custom ones or fractional frame-rates.
Custom resolutions added to this file also doesn’t show in Settings.

On Edge2 Android 13 box firmware it worked correctly.

Can someone find out from Rockchip if there is a patch or some update available to also support this on Android 14?

If I try to add this to Edge2 ‘user’ firmware, it only shows the Khadas kernel logo then no signal on the tv. Is there any other change Khadas made that might interfere with it?
It worked correctly on Android 13 ‘user’ firmware.
