I go into overwatch and for some reason it pops up on my second monitor
its also in a weird resolution so when i try bringing it to my main monitor
And making it into fullscreen it just goes black and brings me back to battle net and doesnt allow me to click back into the game.
I tried changing the resolution to what it should be on my main monitor and then fullscreening its still the same problem
My grammar isnt all that good nor my English but i really dont know what to do to make it fullscreen without it tabbing me out of the game.
Hey,
Does the game crash or are you simply being disconnected?
Na na na na na na na na na na na na na na na na Survey!
I can still hover over the taskbars overwatch icon and see the game, it simply kicks me out of the window. Whatever i do it kicks me back out.

Go into display settings, click “Identify”, which will show you a large number on each screen. Note the number shown on your main display.
In the dialog, you will see two displays. Select the one having the number you took note on. Check “Make this my primary display.”
Apply and OK all the way back. Try launching the game.
Thank you both, i will defenietly try this out.
