After updating to macOS Ventura 13.4.1 (22F82), my Mac is showing a duplicate of the same 1 monitor connected.
I've tried unplugging the monitor via USB-C, resetting the monitor factory settings, and System Settings continues to think there are 2 Displays connected
Any idea how to reset the Displays menu / help the OS see that there is only one monitor connected?

Restarting and safe mode specifically each have a tendency to resolve unexpected behaviors on their own. If they do not, a new user will help us determine if the issue is occurring system-wide, or if it is specific to your user account.

Thank you for your insightful suggestions, Lindsay! I was able to determine that my monitor was showing up 2x in settings because I had the Mac connected to the monitor via HDMI and USB-C both, so the Mac recognized it as two separate signals to send.
Unplugging the HDMI cable seems to have solved the problem (now only 1 display is detected, as USB-C)
Cheers!
