Why not just leave the monitor off?
I never turn on my monitor unless I need sighted assistance with my
computer.

Lloyd:
What you are suggesting is in line with what Steve (KW3A) suggested earlier
in this thread.
I will first systematically dis-connect peripherals while leaving the main
desktop unit on, to see if any of them are the culprit.
If the culprit happens to be the monitor, I have another one that I can put
in its place if needed.
Will probably be a project for later today or tomorrow, although we are
going to be hosting a dinner for a few work colleagues later tomorrow
afternoon here at the house, which I will have to help prepare for.
I appreciate your suggestions very much.
