what could cause one of my monitors to be stuck at 640x480 only on the first boot after a system update?

when i boot my computer after having run an update, my primary monitor (which should be at 1920x1080) is stuck at 640x480. interestingly, when i reboot and change nothing, it fixes itself until i run another update.

i'm on arch, using nvidia 555.58-2, on plasma 6.1.1-1. the monitor in question is DP-0 in the system info below.

what could be causing this and how can i fix it?

i've been having this issue for a while while kinda just dealing with it because it was something i could easily work around by booting my computer twice, but i'd really like to get it solved.
