HDMI Picture goes on and off every few seconds

[Onelight]

Hi all,

I have Armbian 22.08.6 Jammy with Linux 5.15.74-rockchip with Desktop running on an "Asus Tinker Board Rev. 1.2".

 

My Problem is that I get no stable HDMI Connection. Picture is appearing and disappearing every few seconds. Changing Cable, Monitors, Resolution and Refreshrate doesn’t change the problem. 

 

After Research in the forum I saw that I should provide „armbianmonitor -u“ here:

I would be able to compile a custom

image, but I don‘t know where to start bugfixing because I am no HDMI Expert.

 

Maybe it has something to do with a Sync-Problem like described here:

Thank you for help!

Update:

Tried another cable and it now works!

 

I used HDMI-to-DVI Cables before and now I tried with a HDMI to HDMI Cable and it works.

 

I am not sure why it doesn’t work with the dvi cable, maybe because of the missing audio channel from dvi!

 

Thanks!
