Hello Lockergnome Community,
Quite a long time ago I bought myself a mini display port to HDMI connector to go to my TV from my MacBook. As nice as it is to extend a desktop to a tv, I never figured out how to properly go fullscreen on a second monitor. For example, iTunes. When I click the icon to go full screen, I get that grey screen on my secondary monitor and my Mac's monitor takes over the visualizer. This defeats the point of the second monitor as it is simply displays that grey screen. Does anyone know how to have full screen apps work correctly on a second monitor without making it the primary display? This would especially help later on as I am soon going to buy the rMBP which supports 2 monitors.
Any help is appreciated,

As far as i'm aware you can't have something full screen on a secondary monitor, however, you can change your primary monitor in preferences - displays, i believe you need to drag the menu bar to the other monitor to make it the primary monitor, then anything you maximise will fill that monitor.
