Optimization and stutter from monitors?

[rifat10467]

Hey folks, 

Just added a dell 27 inch gaming monitor 144hz/1ms to my setup of two lg 4k 27 inch monitors 60/75 hz and i'm noticing a few issues. 
1) When i move things from monitor to monitor it faces stutter. 
2) For some reason, whenever i play overwatch it minimizes the game (on the dell) everytime i play the "first" game. 
3) Sometimes, it chooses to change the main monitor? It's hard to explain but lets say my main monitor is number 1.. none of my apps on the side show up on monitor 1 till i turn monitor 3 on? 


Off topic, but anyone know any cool wallpapers i can put on my monitor? I have a
