DisplayPort not working

Hi all,

I've got three ASUS PB278Q monitors, and I've been using the DVI output from all three for my nVidia GTX 690 graphics card (which has 3 DVI inputs).

Now I have a new EVGA Titan X, but the monitors will only be detected if I use the DVI or the HDMI input. DisplayPort won't work at all.

I went back to my GTX 690, which also has a MiniDP input. I tried to connect my monitors through their DisplayPort output into the MiniDP via an adapter, but this won't work either!

It seems the DisplayPort simply isn't working on any of the monitors. I don't know if this could be a system thing though? I've tried 2 different DP cables.

I'm using Windows 7 64bit Pro. Graphics drivers are up to date.

I've sent an email to EVGA, and I'm awaiting their response.

Any ideas how I could proceed??
Thanks,
Dave.

If there is a World's Biggest Douchebag award for Saturday 3rd October 2015, it firmly belongs to me.

Turns out I didn't have the DisplayPort cable firmly seated in the back of the monitor. Everything's working properly now.

Sorry for wasting everyone's time :/
