I wonder when we stream a movie from macbook air to Apple TV, can we turn off MBA screen so that it can save battery.
Can you turn the brightness right down until the screen goes off?
Assume you are on battery power not plugged into the mains.
In case I'm plugged into the mains, is there an option to turn off screen. because I don't wanna 2 screen playing the same movie. Look very distracting.
