Mac display not working after updated

I have a Mac Mini with two displays and after the recent macOS Ventura 13.0.1 update my USB-C display stopped working.

macOS wasn’t recognising it and the monitor was showing a message telling me to check my signal.

I found a fix on a forum that worked for me.

Delete the following file and restart.{XXX}.plist

To do this open Finder and choose Go to folder in the Go menu.

Put this in the Go address bar.

Find the file called{XXX}.plist and delete it. Then restart.

I also had to power cycle the monitor.
