Hi, just posting a heads up: I had my Cinema HD Display replaced today because the "old" one I got last week exhibited very bad ghost images. For example, if I move the iChat buddy list window to a new spot I can actually read the text on the old spot for almost a minute.
Well, the new one is exactly the same. I switched to using LCDs exclusively with the new PowerBooks in 1998, and have never seen anything like this.
I'm using the 17" PowerBook and Apple's DVI-to-ADC converter, though I can't see that affecting things since its supposed to be all digital.
Any other Cinema HD users care to chime in? It's weird that I don't remember seeing this discussed before.
