No digital signal. Wrong cable?

(the question seems to have changed, so I thought I should start a new thread)

I'm trying to figure out whether or not I should RMA my new video card. It's an XFX 7900GS, w/ dual link DVI.

My monitor is a ViewSonic 22" Widescreen and it has inputs for VGA and DVI.

I get no signal when I use the DVI cable, but if I use the VGA cable with an adapter to the vid. card it works fine. (I just exchanged the monitor for a new one, so I know it's working ok)

I don't know if it's important, but I noticed that even though they're both DVI, the cable from the monitor looks a little different than the adapter plug. Referring to this picture:

The end of the cable from the monitor looks like it is DVI-D (single link) and the adapter that I'm using with the VGA cable looks like it is DVI-I (dual link).

The input on the monitor looks like the DVI-D (dual link) picture, and the output on the card look like DVI-I(dual link), but it has a + shape instead of just a - shape.

Is any of this relevant? Is it worth getting a different cable or should I just go ahead and RMA the card?

I just don't understant why a dual-DVI card would only be able send an analog signal.

the output on the video card is dvi-a, which is why you can use the adapter.

there's no reason for the analog signal to get carried to your digital monitor, so that's why the input's a dvi-d

are you sure you have your monitor set to auto detect or dvi?

try a lower resolution, too. some cheap dvi cables don't work well with high resolutions. Typically they just get blurry, but it's possible that you'd get no signal at all.

Yeah, the monitor auto detects the signal. I can manually switch it to digital, but it reverts back to analog. If I start the computer with only the DVI cable connected it just diplays "digital - no signal".

Plus, it worked fine with my old card, a 7300GT, using the same cable on the same resolution. It only stopped working when I got the new card, but I want to explore all possible solutions before I RMA it.
