[HELP!] Second Monitor Goes Black When Playing Games In Fullscreen Mode

Question

Hey There! 🙂I Recently Added A Second Monitor To My Setup So I Can See Skype Calls And/Or Google Things While Playing Games In Fullscreen Mode. But Whenever I Turn The Game To Fullscreen Mode My Second Monitor Goes Black. I Would Like To Play In Fullscreen Mode So I Can Get The 1080p Quality Out Of The Gameplay For Me To Record/Upload. If You Have Any Idea How To Fix This Problem Please Respond.                                                                                                                                                                                                -Tim

Try changing the setting for "Displays have separate Spaces" in the "Mission Control" system preference.  You have to logout then login for the change to take effect.
