When I alt tab from a fullscreen game, both of my monitors go black for 3-4 seconds and when I go back to the game from the 2nd monitor, it does the exact same thing. I believe that I have narrowed it down the my graphics card (gtx 1050 ti with only a Display port and an HDMI port, so it may be struggling switching between the two inputs) or because I am on Windows 7 (though I don't know if this is related at all). Do I need to graphics card with two Display Ports? or do I need to switch to Windows 10? Anyone have this same issue?
