Custom Resolution for HD-ready TV

Hi all,

Is there a way to configure a custom resolution in Dietpi ?
Tried the ubuntu way with xrandr but doesn’t work.
Tried to modify dietpi.txt on the boot partition, doesn’t work either.

I want to set it up with 1366x768 @ 60hz, because the image is cropped when set to 1920x1080 on my TV. As well as 720p and all. (Really don’t know why, tho). I have set this up on my Rasppi before but on Odroid with Diet, it seems complicated.

Does everyone knows how to add this ?


Which device?

All the settings are in the file below, but the list of supported resolutions is different for each Odroid board.
