Seems to me the issue is with the Monitor? I can find out by swapping it but you're the goddamn expert! You tell me!
Edit: turned the PC off and when I turned it on got a message about Windows not loading properly and advanced repair or restarting. Fiddled about in Settings with Windows updates and ... the PC (desktop) is going ok for the moment.
