Problem With My LCD Monitor?

Having an intermittent problem with my LCD screen. When viewing a white page, such as Google, the white will sometimes take on a blueish tinge. It will turn blueish for a while, then snap back to white.

System info:

ViewSonic ViewPanel VE150B

Dell Demension 8200

NVIDIA GeForce 2 MX/MX400


Any ideas?

Check for vga cable problems, try flexing it along its length. How about moving (tilting, rotating) the display...any effect?
