I'm stuck at 640 x 480 resolution

I used my computer this morning and everything was working fine. Turned it off and came back a few hours later and my 2560 x 1440 display is stuck at 640 x 480. I reinstalled the nvidia driver 370.28 but that didn’t help. I verified with lsmod that the nvidia driver was loaded. Also, I launched the nvidia-settings app and it showed it was using the 370.28 driver but there is no other resolution available. Anyone know what’s going on here?

Start by examining the /var/log/Xorg.0.log, and you need help interpreting it, you can copy/paste it to https://paste.opensuse.org/ then post the link to it here.

Sounds like you lost the EDDI handshake… Using a KVM switch? check cables are fully setted. Check xrandar has to say about available resolution.

How do you update?

This problem seems to have fixed itself. Very weird. Thanks for the responses.
