DVI switchbox for 30" ACD?

Can anyone make a recommendation on a DVI switchbox that will allow me to run a macbook pro and Mac Pro on the same 30" apple cinema display?

ATEN makes some good ones.

I had a look at the Aten VS261: http://www.aten.com/products/productItem.php?pcid=2005010513171002&psid=20070130154429002&pid=20050222161615002&layerid=subClass6

It sounds like the maximum resolution is 1920x1200. This is a far cry from the 2560x1600 resolution of a 30" ACD.

Anyone know if the Aten DVI switch or any other DVI switch for that matter will support 2560x1600 with the 30" apple cinema display?

Looks like I answered my own question. Newegg lists 2 DVI switchboxes that support 2560x1600. The belkin sounds like it is worth a try:

It's just a switch, how can it know what resolution is being used?! -lol

It's not as simple as just electronically connecting the wires when the switch is changed. The switch must interrogate the display DDL and then present the same DDL continuously to all attached computers to prevent them thinking the screen is being disconnected then reconnected.

It needs to support dual-link connections. Dual-link requires significantly faster circuitry to support the passing through of the signal so switches will be much more expensive.

I'm not aware of a DVI switch that can handle dual-link displays (and I've been looking). No doubt they're on the way, but that doesn't help right now...:(

The Belkin one linked above explicitly states it's dual-link capable. :confused:

Ah, that explains it. Thanks!
