My main goal to set up 2 x 4K monitors for editing videos. I currently have a Dell P2715q IPS 4K monitor that runs at 60Hz via Displayport. My 780Ti has an HDMI port, but I'm not sure if its 1.4 or 1.2 since 1.4 can drive 4K at 60Hz or I may be wrong. My question is, I would like to get another P2715q but I'm not sure If I can run that via the HDMI port at 60Hz.
