How does the Mac Mini handle itself when being used directly with a large TV? I have a 1080p TV, 46" and plan to use it as a computer to show people how to use iPhoto and iMovie and such. I had my MacBook Air hooked up, and it worked fine as a second monitor but there was minor lag at times. When the Air was hooked up to my Apple 24" LED there is no lag at all so I was wondering if the screen size has anything to do with it. Does the Mini handle this situation well? I am currently waiting for the refresh, but wanted some opinions in case this has been an issue or not.
