Recently I got a second GTX 980 to SLI with my first one, and now I am unable to use both of my monitors. When I had just the one GTX 980 I was able to use both monitors with no problem, but now since I got my second GTX 980 (now the one I am trying to hook up both monitors to) I can only get one signal to work. Both monitors work, and the connections are fine, it just only detects one of the two.
