This has been driving me nuts. What is Dual Link DVI and which Apple adapter do I need?

Here’s the answer:

Apple's mini displayport to dual-link dvi adapter

A dual link dvi adapter supports resolutions higher than 1900×1200, up to resolutions of 2560 by 1600 pixels to be exact.

While some TVs or displays support up to 1900 x 1080 (1080i or 1080p). For resolutions up to 1900×1200, use the typical mini displayport to dvi adapter that came with your mac. The mini displayport to dual-link dvi adapter is for people who want multiple displays or the 30″ apple cinema display (support resolutions of 2560 by 1600 pixels).

Ok, glad to have that figured out!
