rpm-ostree. I confirmed the EDID file is in /usr/lib/firmware/edid/my_edid.bin and the kernel is loading it (drm.edid_firmware=HDMI-A-1:edid/my_edid.bin is in proc/cmdline).edid-decode output confirms the EDID lists 1920x1080@60Hz as the preferred and native mode.video= and nvidia-drm.primary= to force the resolution, but they either had no effect or made the situation worse (reverting to 1024x768). My dmesg logs show the NVIDIA driver explicitly stating: "User-defined mode not supported: 1920x1080".
