Here at Cult of Mac, we’ve been playing around with our new Retina MacBook Pro — look for our review tomorrow — and we decided to install Mountain Lion on our shiny new ultra high-res notebook and take Apple’s latest operating system for a spin.
It runs a peach, of course, but one thing we noticed when we were playing around in the Displays preferences in Mountain Lion was that there is an option to set your display resolution as for “Best for AirPlay,” along with the other two regular options which appear in OS X Lion: Best for Retina display, and Scaled.
