Rock 5B - 4k120 not working
Hi,
when I select 4k 120hz, my tv stays black and Ubuntu switches back to 4k 60hz after a few seconds. I use the latest Ubuntu 24.04 image with 6.1 kernel on my Rock 5B. My pc (Nvidia gpu) is able to output 4k120 using the same cable and tv. Do you have any ideas? What am I missing?
