Hi there, I am trying to connect a LG 32UD59 UHD monitor to a MSI Armor RX570 4G card via a HDMI2 (cheap) certified cable. Unfourtunatly the setup only runs at 30Hz, whereas when booting Windows it automatically selects 3840x2160@59Hz. I played a bit with adding the modelines manually, however when enabling those new modes the screen goes black and in syslog I find the following entries: [ 571.174813] [drm:atom_op_jump [amdgpu]] *ERROR* atombios stuck in loop for more than 5secs aborting [ 571.174862] [drm:amdgpu_atom_execute_table_locked [amdgpu]] *ERROR* atombios stuck executing D850 (len 824, WS 0, PS 0) @ 0xD992 [ 571.174908] [drm:amdgpu_atom_execute_table_locked [amdgpu]] *ERROR* atombios stuck executing D70A (len 326, WS 0, PS 0) @ 0xD7A6 Xorg.0.log: https://pastebin.com/LmZ0bvyL kernel log: https://pastebin.com/rXGVMTnV Help would be really appreciated - I am rather latency sensitive and those 30Hz are driving me nuts ;) Best regards, Clemens _______________________________________________ amd-gfx mailing list amd-gfx@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/amd-gfx
