Fullscreen games - 2nd display goes black

[LilaQ]

Hey guys,

 

in several games, when using the fullscreen-mode (or if they don't even offer anything else than going fullscreen) I'm experiencing that my second monitor goes black and thus is unusable for me.

But I need to have certain windows open in my second monitor, even when I'm playing a game.

 

Checking "Displays use own spaces" didn't make any difference to this problem. And of course the games I'm talking about don't offer a windowed-fullscreen mode.

e.g. Game of Thrones, or Leisure Suit Larry 1, just to name some which display this problem.

 

Is there any way to force the game to only use a single monitor and leave the second one for normale OSX-use?

 

Thanks in advance for the help guys

 

Best regards,

LilaQ
