So the X800XT seems to work fine.... except the DVI port doesn't. I did the usual cleaning with plenty of contacts spray which solved this problem on other cards but the DVI port refused to work. Black screen, but I can load into Windows. I just don't get anything on screen. Maybe something could be broken on the card? Is this a common issue that you folks know? Or should I try again with cleaner/newer cables, more contacts spray?
It is very common for heavier cards to have damaged SMD components near the DVI\VGA ports from my experience. I assume it happens when cards are stacked together or put in a box, the metal back plates from other cards scrape parts off.
The most fragile ones are the little three or four leg inductors (filters), but I believe those are usually just on the VGA pins of the DVI port.
There is an example of this kind of damage on a 6800 Ultra in this thread.
I would start at the DVI port and go over all of the components with a magnifier and good lighting. Hopefully it is just a damaged surface mount component.
Also, have you tried a DVI to VGA adapter on that port? It uses a totally different signal path, but it would be worth checking, just in case.
