My monitor is locked at 640x480 after hardware upgrade
@ShadK428 · 2026-04-30 · via CachyOS Forum - Latest posts
I’ve been running CachyOS-KDE for a few months and just upgraded my system (hardware details below). Switched from Nvidia to Radeon gpu and my second monitor is now stuck at 640x480 and flickering with horizontal white bars. The DP cable works on my other monitor, all ports on the gpu yield the same result, the issue persists both on my old Cachy install and a fresh install, as well as on Cachy-LTS. I ran cachyos-bugreport.sh and found these errors: [ 7.653276] [drm:dm_helpers_read_local_edid [amdgpu]] *ERROR* EDID err: 2, on connector: DP-2 [ 7.654727] amdgpu 0000:03:00.0: [drm] *ERROR* No EDID read. Monitors: HyperX Armada 27 + AOC G2460PG (the AOC is the problematic one) Replaced hardware: Motherboard: MSI B550 CPU: Ryzen 5 3600x GPU: Nvidia 2070 Super New hardware: Motherboard: Asrock B850M-C CPU: Ryzen 5 7500x3d GPU: Radeon 9060xt Any ideas how to solve this? I’ve seen a couple other threads with similar issues but I’m still new to linux so I’m a bit lost. I’m not sure how to attach the full bug report, but am happy to do so if someone can tell me how. Thanks in advance!
