Game appearing on second monitor

[le epic swag boss]

Whenever I alt-tab out of the game and come back in, it switches to my other monitor and there's no way to switch it back without restarting. Any fix?

I know this is over a year old, but I wanted to post that I was also having this issue and found a workaround for anyone who may run into this in the future. Just open your Display Settings in Windows and manually swap the positions of the monitors from 1|2 to 2|1. It will be a little confusing, as now your directions are reversed when doing things on your computer (left is right and right is left), so just remember to swap them back when you are done playing! Hope this helps someone!
