Simple answer really! Your monitor is gay!

Try another monitor for a while to isolate to the computer or the monitor. I've had similar problems with loose monitor cable. Have you giggled the cable around to see if you can cause the problem? Most likely cause, monitor intermittent. Is the monitor under warranty (a few have three year warranty)? New monitors are inexpensive, if you verify the monitor is bad it would probably be cheaper to buy new than try to fix the old one. Tim

hahahah. Can't beleive your logic didn't figure out what the problem is. Either the cable on one of the ends of the monitor has a bad connection to the green and especially blue gun pins, or your monitors green and especially blue guns are going. Time for a new monitor. 99% sure that's what it is. Throw it away before you loose your sanity. Older monitors end up doing this in their older days. Lower quality ones do too. Micron monitors sometimes do it also. :)
