hello, I'd like to report this issue that I am having since I upda= ted my display (samsung U28E590). The amdgpu does not support the native re= solution 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 i= ssue 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, sa= me results!): 5.9.16-200.fc33.x86_64 #1 SMP Mon Dec 21 14:08:22 UTC 2020 x8= 6_64 x86_64 x86_64 GNU/Linux
Monitor: Samsung U28E590.

description:
If I boot the system using amdgpu and no video mode selection, the sys= tem boots but I don't get a screen during boot and in wayland. I can co= nnect 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 w= hen wayland starts (because the default resolution is 3840x2160@30Hz).
