Yes, rebooting fixed it, at least for now.

I have 4 displays. Here's some info from nvidia-settings:

It was the DELL U2410 (HDMI-0) display that flipped out.


What desktop are you using?

KDE

Hmmm, it looks like my motherboard firmware is behind. It's a B450 tomahawk
mc-7c02 running E7C02 AMS.130 from a few years ago. There have been several
updates since then. None of the updates look relevant to this problem and
I'm a little reluctant to update motherboard firmware. As for the graphics
card firmware, I'm not sure. The VBIOS version reported above is
80.06.10.00.5d.
