I'm expecting delivery of my new dual 2.66 8core Mac Pro with updated new Radeon card any day now. I was planning on using my 23" cinema HD Crystal display with it until I can afford a new 30" display - totally assuming that because it works with my other macs perfectly it will work with the new one. But here lies a problem - I've heard rumours that this apple display isn't supported!!!!

Also just found this on the apple forum
Apple - Support - Discussions - Apple Cinema Display 23" (Clear Case) ...

Can anyone shed any light on this?
