Hi, i am sure this is simple, im just not getting it. tried external screen search and got nothing..so.....i hooked up the '11 MBP to external screen, all i get is the "space" background. If i move the mouse over to the right it appears on the external monitor, but nothing else. I can double tab and get resolution settings for external screen, but i can get any progrmas to display in screen. What am i doing worng. I just want the monitor to show same thing as MBP screen. Thanks
