You need a Dual-Link DVI adapter:
Mini DisplayPort (MDP)
Mini DisplayPort is the current digital standard on all current Macs to transfer video to an external display or TV. It has been introduced in 10/2008 with the release of the Unibody MacBook and MacBook Pros and has gradually been adopted on all other Macs.
MDP is capable of transmitting video, and since 2010, audio too. MDP is a miniaturised version of DisplayPort. It is also license free and can support resolutions of up to 2560 x 1600, which Mini DVI and Micro DVI are not able to do.

If you have the 20" ACD listed in your sig you don't need the dual link cable. Just a regular mini display port to DVI cable available for around 29 bucks from Apple.

That is correct, I was not thinking clearly when I replied, and mistook the USB and Firewire cable for the Dual Link DVI setup, which is only needed for the 30" ACD.
Any good MDP to DVI adapter will work then, Monoprice can be used for cheap ones.

Phew - good news! Question: why are those other cables attached to the display then?

Thanks all.. :)
