Hi

Ive just installed the latest version of Armbian (Ubuntu Noble+KDE) and everything works fine except it looks like it is not detecting my TV resolution correctly.

I can choose 1920x1080@120hz but if I try yo go to 4K I can only select 24Hz

 

I attach armbian monitor logs url,  modetest  and kscreendoctor

 

My cable is HDMI 2.1

 

Any help would be appreciated
