Yes, absolutely. Do you only get a black screen?
That would certainly be a rather big bug.

Btw, should the driver switch to the lower supported resolution then?

Hello. This resolution is supported by the Apu and the motherboard
specs. Will try what you suggest and let you know

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 since 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 radeon 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.
description:
If I boot the system using amdgpu and no video mode
selection, the system boots but I don't get a screen during
boot and in wayland. I can connect using ssh, so the system
is running fine, just no display; If I force a full HD
resolution with "video:" in the kernel line, I can see the
boot process but the screen disappears when wayland starts
(because the default resolution is 3840x2160@30Hz). Using a
full HD monitor results in no issues, so it must be related
to this very 4k resolution.
As I have already stated, radeon module works with the same
software/hardware configuration.
thanks you so much for your time :-)
