Much to my dismay, my G4 Powerbook 12" is not talking to my projector - an NEC VT460K - very nicely any more. When I try to use the projector, the picture has a bright yellow tint to it. Ive mucked around with colorsync and have been able to reduce the brightness of the yellow considerably, but not enough.

I have used mini dvi to vga and mini dvi to svideo connectors all to no avail - it stays yellow. I have tried the projector with another powerbook - a G4 15" - and it works fine.

Can anybody offer an explaination or, even better, a fix?

Pretty please
