Hi Davide,

adding a few of our AMD display people.

In general as already suggested by others opening a bug report to track this is the right thing to do.

In the past we had a few bug reports like this because amdgpu is more strict in checking hardware limitations.

For example it can be that your HDMI port on the board can only handle a certain maximum pixel clock, but radeon is ignoring this while amdgpu isn't.

What you can try to do is to manually override the used mode, e.g. copy the modeline used when radeon is active and manually add that using xrandr when amdgpu is active and see if it works or not.

Regards,
Christian.

hello, I'd like to report this issue that I am having sinc= e I updated my display (samsung U28E590). The amdgpu does not support the native resolution of my new monitor, which is 3840x2160. Using a HDMI or DVI connection (I tried both, same results), the maximum supported refresh is 30Hz, so I'm stuck with that (don't have a displayport). The radeo= n module works fine, I'm having this issue just when I use amdgpu (which I'd like to, because performance is better).

Some info of my hardware:

cpu: AMD A10-7870K Radeon R7, 12 Compute Cores 4C+8G
kernel version (I tried different ones and different linux distros, same results!): 5.9.16-200.fc33.x86_64 #1 SMP Mon Dec 21 14:08:22 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux
Monitor: Samsung U28E590.
