I just tried hooking my MacBook Air up to my LCD TV with a thunderbolt to HDMI adapter. It worked, but I noticed that there is a menubar at the top of the TV screen and it stays there all the time, even when I put a video in full screen. I can click on the menubar on the laptop and it takes the menubar on the TV out of focus, but it's still there and annoying when watching a movie. Is there any way to get rid of the menubar from the TV screen altogether? I don't need it on both the TV and the laptop screen.
