I just bought a new Viewsonic display and connected it to my macbook. Two questions: 1) Is ther any way to set it up so that I can use the large display while I have the laptop closed? Because right now the laptop is open and is mirroring everything on the large display and I'd rather have the laptop closed. 2) Is there a way in Mac OSX to ensure a perfect picture on the screen? Or do I have to keep messing with the contract/brightness settings myself? Thanks.
