Dell 2007 WFP DVI Problem

I’ve been having trouble with my new Dell 2007WFP widescreen monitor, since I was given it back in December.

The monitor comes with a single link DVI-D cable, which I was attempting to use with my Geforce 6800-GT graphics card. However hard I tried I could not get the resolution above 1024×768. When I tried to step up from 1024 the screen would go blank and that was it. The 6800 had two DVI-I connections on the rear, and the only way I could get the thing to work was with an analogue cable and a DVI to analogue adapter. Not knowing much about DVI inputs etc, I put this down to some wacky driver problem, and resolved to wait until I built my new PC at the end of January (with the release of Vista).

January came. I built a brand new machine; Intel Core 2 Duo E6600 (Overclocked to 3.2Ghz), 4 Gigs of Ram, Nvidia 8800 GTX, Lian-Li PC-1000Plus case, and lots of hard disk space. Very nice indeed, but errr………same problem. I could only get it to work with an analogue cable.

So I spent today googling the problem, and from what I could tell I shouldn’t need to use a DVI-D dual link cable unless I used resolutions above 1920 x 1080, and I couldn’t even get above 1024×768. So I thought I’d take a punt, I whipped down to Maplin’s bought a DVI-D dual link cable, and now it works perfectly!
