I'm trying to get my dual monitors to work but unable to. I have one monitor hook up w/ dvi and the other on display port. The Dvi port works fine and DP shows up on both Window 7 and Nvidia set up. When I click on the monitor that's hooked to the DP, it won't allow me to set it up or apply the setting. What do I need to do to get this activated? Thanks in advance!!
