I attached a TV to my MacBook Pro 13''. I find annoying to have my MacBook Pro's screen turned on while I watch TV (of course, the signal is sent from my MacBook to the TV. I use this configuration in order to play games, and watch DVD movies).
Is it possible to turn my MacBook Pro screen off, and just see the video signal in my TV? I have search everywhere without finding an answer.
A last detail: it would be great to turn my MacBook Pro's sound off while I watch the TV attached to it.
Thanks in advance!
PS: Please apologize my bad english.
