This happens on wayland only. I have two 27" 4k monitors. The primary one switches to 480p after every suspend and things become massive that I can barely do anything. Rebooting doesn't fix it. Sometimes, I do manage to get to the display settings, but changing the res back to 2160 doesn't bring the "apply" button back, it stays greyed out. My only solution is to switch to x11 then back to wayland. Even then that may work or may not.
I have both monitors at 127% scaling, btw.

STEPS TO REPRODUCE
1. 4k monitor and switch to wayland
2. suspend and wake the machine


OBSERVED RESULT
Resolution sets to 480p and can't be reverted back to the screen's native res

EXPECTED RESULT
Resolution to stay set at the monitor's native resolution and not switch to 480p where things become massive
