Dual-link DVI
Ok... so I've always been a bit confused on this:
My computer has two dual-link DVI outputs currently... naively I would imagine that should mean I can connect up 4 monitors each with a max resolution of 1920*1200. Yet... I'm at a total loss to find a cable that would allow this to be done. I take it that the "dual" in the sense used here is just implying some kind of doubling of available bandwidth?

Re: Dual-link DVI
Yes that is effectively correct.
You cannot connect 2 monitors to a dual link DVI connector. A single link DVI is good to pump data to feed up to 1200 * 1600 max, a Dual Link DVI connection effectively doubles the data transmission rate cabability and is required for larger resolutions.
