Tarrak ... erhh Kraxis had the same problem some time ago, dunno if he resolved it yet, I think he has, you can ask him.

Anyway the only solution given in that thread was this one:
Sometimes one (or more) of the pins in the VGA (or other video) connector doesn't make good contact if the connector is loose. That can cause your whole screen to go vagina-pink, since one of the color channels isn't getting sent.
Make sure that the connectors are screwed in tight, and check that the mechanical connection on your monitor or video card is good enough to withstand gravity. Sometimes there are mechanical obstructions that prevent you from screwing it in properly.
