I didn't know that. I just knew the one on the back of the Precision  
390 I got at work was definitely not DVI :)

That's pretty common on video cards, I've noticed it a lot on  
consumer and low-end pro cards. It's possibly related to them not  
having Dual-Link DVI ports? I know Apple's 30" display requires a  
Dual-Link port to work at the high res it uses. DVI being a digital  
matrix, rather than an analogue signal, requires extra wires to do  
larger resolutions past a certain point.

I think this is the difference between DVI-S (single link) and DVI-D  
(dual-link) cables? I know a lot of cheap DVI cables only have half  
the pins in the plugs.
