You might try enabling DC (the newer modesetting infrastructure).  App= end amdgpu.dc=3D1 to the kernel command line in grub.

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 resolu= tion of my new monitor, which is 3840x2160. Using a HDMI or DVI conn= ection (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 wh= en I use amdgpu (which I'd like to, because performance is better).

Some info of my hardware:

You might try enabling DC (the newer modesetting infrastructure).  App= end amdgpu.dc=3D1 to the kernel command line in grub.

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 resolu= tion of my new monitor, which is 3840x2160. Using a HDMI or DVI conn= ection (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 wh= en I use amdgpu (which I'd like to, because performance is better).

Some info of my hardware:
