I agree... It sounds like (looks like? ;-) ) a display dialog that is
superimposed onto the screen by the clever electronics in your monitor.


Are there any control buttons on the monitor that are being
pushed/disturbed by something brushing against them?

Might you have a lead too loosely plugged into the monitor?

Or is the video lead loose into the computer?

Or even some remote control switching input channels?

(Or a cat chewed the cables??! Has happened!!... And nope, not my cat.)


Hope that gives you a few clues.

Let us know what you find,

Good luck!
Martin
