Does anyone know the actually compatibility of the Mac Pro with the Apple 24" LED display via Mini Displayport? I would like to move my Mac Pro out of the studio and into the room below. The ideal solution would be to simply run a single Mini DP from the Mac Pro (ATI Radeon HD 4870) to the Apple Monitor which has USB, iSight, video and 2.1 sound support. The question is do all those items work over the Mini DP? I would be using this cable. Apple support gave me a mixed answer, I know all those items will work via a MacBOOK Pro, but hoping the MacRumors people have a solid answer on this. Thanks in advance!
