Received my new Mac Mini today with the intention of using it with my 20" Apple Cinema Display. Plugged everything in and the screen didn't turn on. Plugged the old Mini in and the Cinema Display worked. Tried the adapter with my old Mini and it worked. Plugged my new Mini into the TV and it worked. For some reason my new Mini isn't working with my old Cinema Display. Called Apple and they had me reinstall the hard drive.
