Multi Monitor Game issue?

I've had this issue with certain games that I'd like to figure out if theres a way to solve this. So I'll be playing a game on my main monitor with a controller While I'd like to click off and browse the internet while I'm playing but sadly it always pauses the game. Anyway to make it so I can keep playing while using other monitor's? Some games allow this while others don't and I'd like to figure out a solution for all my games so I can have a more enjoyable time. Thank you for your time.
