Setting up two monitors

[tal_1_]

Hi, I have just got my new monitor and now I got two monitors but,If I play on one monitor and move my cursor to tthe other one and clicks on something on the other monitors it gets out of my game as alt+tab does and thats actually why I wanted two monitors (gaming on one and on the other to do something while gaming).
Thank in advance guys I hope you'll understand!

You have to play in windowed or borderless windowed if you don't want it to minimize.

But if I play on borderless I can't change the brightness of the game
