Interesting, I got it to work using output HDMI-A-1 res --custom 640x480@75Hz. Using output HDMI-A-1 res --custom 640x480@60Hz and output HDMI-A-1 res --custom 640x480 will result in a black screen. Maybe it has to do with my second deactivated laptop screen?

Why are you using --custom when it's a natively supported resolution of your monitor?

Sounds like Sway does the right thing, and doesn't get an error from the kernel:

00:00:01.651 [INFO] [backend/drm/drm.c:852] Registered custom mode 640x480@59375
00:00:01.651 [INFO] [backend/drm/drm.c:803] Modesetting 'HDMI-A-1' with '640x480@59375mHz'

Can you obtain DRM debug logs? See https://github.com/swaywm/wlroots/wiki/DRM-Debugging

@kiljacken
Oops, my fault. Removing the --custom parameter fixed the issue. Thank you.

@emersion
Just incase, here are the logs.
