I have a Geforce 4600 and I use DVI, all you have to do is boot up your machine with the projector on and connnected via DVI (nothing connected via the analong 15-pin port). The driver should pick it up. I have a Samsung 191T Monitor and this is all I have to do. If you need to do something special nvidia has great documentation and you whould just need to play around with the options. The
"DigitalFlatPanel" option refers to the DVI port.
