So I just got the fancy new samsung 4k monitor and it's not working through displayport. I ruled out the monitor being faulty as well as the cable because they both work on my other rig with a 780 ti installed with windows 8.1

This machine has windows 7 64 bit and a gtx 970 directcu mini by asus. Anyone out there know what could be causing this problem?
