Hey folks. I'm a noob so please go easy on me. I've hooked up my mbp to a bigger monitor so i can watch movies etc and have successfully got the monitor working. I used a VGA cable. Right now I have the same things showing on both screens. Is there any way for me to turn off the macbook pro screen so it's only the big monitor being used? And on the other hand how could I turn off the main monitor and only have the macbook pro screen working?
