Are you using your VGA system with fluorescent lighting ?

	Flourescent lighting flickers at 60Hz. This will interact with a
	display that is refreshed at 60Hz. Neither item is synchronized
	so you have an interference pattern that moves. This is why you
	see "10Hz" flicker. Another monitor of the exact same make and
	model will exhibit similar but not identical problems.

	If you use a 60Hz refresh monitor then you should use incadesant
	lighting.
