I am going to add a second LCD to my 20" aluminum iMac and of course my first choice is to get a 20" cinema display. However, from what I can tell the actual screen on the cinema display is a couple inches lower than that on the iMac. Anyone have a photo of a setup with an 20" aluminum iMac next to a 20" cinema display? Is it better to prop up the cinema display somehow so the screens line up, or should I go with another display that is height adjustable? I know other 20" LCDs are cheaper, but I'm primarily concern with getting a good looking setup and having the screens the same size and aligned with one another.
