No display using DVI cable.
Works fine using VGA port.
Works fine using VGA cable on the DVI port (with an adapter given with the video card).

My video card is an nVidia 6600 GT with the latest nvidia drivers.
I installed the monitor drivers given on the Dell CD.

When I plug both cables, Windows XP sees correctly 2 monitors, I can configure clone mode, but still no display through the DVI port.

I need to make it work.
I'll change my PC soon (for an HP Pavilion Slimline) and it will have no VGA port, only DVI.

Thanks.
