Dual link should have more pins, and should be the one to the RIGHT if you are facing the BACK of the computer...

Yes, it does matter. Only one of the ports is a dual-link DVI port. I believe it's port #1, but I can't remember which is #1, the top or bottom. If one doesn't work, use the other. Try putting the 30" to it's max resolution of 2560 x 1600. If that port doesn't do it, it must be the other port. The single-link port I believe will just max out at a resolution of 1280 x 800 (or 1920 x 1200).
The female port (on the video card) is no different so what you guys are telling him isn't helping.
To clarify:
Almost all DVI cables and plugs support dual link (as far as cabling standards and the plugs).
Single link uses fewer pins than dual link, but the pins are STILL present (just for show, I guess).
Therefore, it's impossible to tell the difference between dual and single link DVI cable/plug by looking at it.
As a side note, DVI usually sends standard VGA down the same cable as well, so DVI -> VGA "converters" really just change the plug and pinout, and have no complex circuitry inside them therefore, buying an expensive DVI -> VGA adapter is like buying gold plated USB cables... (stupid)

Bottom of the card... OR.. the one to the RIGHT if you are looking at the back of the computer.. or #1...
