I have just built a new gaming system with 2 GTX 280's running in SLI and a single 22" Samsung 2253BW Monitor (which has both a VGA and DVI port).
My problem is that if I plug the monitor into the first of the 4 available DVI ports, everything works during POST but as soon as the Windows drivers kick in, the screen goes blank. The only way I can get it to come back on is to plug in the VGA cable with a DVI adapter, and then Windows seems to re-detect the display and then DVI starts working again.
If I plug into one of the DVI ports on the second video card, I get no signal during POST but once Windows loads, it kicks in and works fine.
Alternatively, if I just use the VGA cable with the DVI adapter, it works every time.
I have disabled the "input source auto-detect" on the monitor so I know it is staying on the DVI source at all times.
I'm pretty sure this is a problem with my display configuration within Windows, but this is the first SLI system I've ever set up and I think that's where I'm going wrong somewhere.
Any ideas? Thanks.
