[SOLVED] No signal from DisplayPorts but HDMI port works?

[PCMDDOCTORS]

Hello all...

I just completed a new build for a friend and when I went to turn on the system I get no signal from any of the DisplayPorts but the HDMI port works fine. You can view the build in the link below. I thought at first it was a driver issue but that did not fix it. Then I tried a different cable and still no go. I'm at a loss, I don't know weather it's a GPU, Monitor, or BIOS issue. I'm pretty sure it's not the Monitor, which by the way is the 240hz version. Can someone please help?

The monitor automatically switches platform correct?

Your monitor could possibly be just running on HDMI mode right now. Tinker with the different monitor settings real quick -- set it to 'gaming mode' if it has one.
