2 Monitors with a 680 Black Screen

So I have a 680 and a 460 as dedicated physics. I had 2 460s in sli before I got the 680. With those 460s I would plug my main monitor into the top video card in the left dvi port and the secondary monitor into the bottom card in the left dvi port as well. With this setup I could play my games and look at stuff on my 2nd monitor at the same time. With my current setup I have my main plugged into the duel link dvi port and the 2nd monitor is plugged into the standard dvi port right below it on the 680 and nothing is plugged into the 460 dedicated physics. The problem is from time to time when I launch a game in full screen non-windowed. My second monitor just displays a black window, not the no input screen but a solid black window. Alt + Tabing the game a few times usually brings the 2nd monitor back but this is a pain in the ass and some games don’t like being alt tabbed. That is the problem that I am trying to solve, also would it hurt performance to plug that second monitor into the dedicated physics card?

 

This is my twitch that has my system information.

I also have swaped the 680 to the top pci slot unlike it show in the picture.That was my bad.

I would try plugging both in to the same card and make sure you have all the right drivers running. Also try switching the cable type to see if something changes.
