GTX 980 3 Display problem

[logicalways]

Description:

 

I've been trying to get 3 Asus displays to run on my GTX 980 for about 2 months now (haven't had a lot of time due to new baby). I have 3x Asus VG248QE displays. I've been trying to get 3 of the VG248QE Displays to run off of display port but not having any luck. I thought one of my display ports was bad on my monitor so I've set up an RMA with Asus to return it. I swaped in my asus PA248Q IPS display into the centre to replace it as a temp from my mac pro. 

 

I can get my centre and right screen to turn on via displayport but not the left one. The left one says "No displayport Signal" then goes into sleep mode.

 

So I've tried each monitor into each port individually and found out it's not the ports because the two good monitors will turn on in any port. I've tried all new cables and same thing, both good monitors turn on no matter the cables used. Nvidia control panel detects the display but the system freezes shortly when I try to select the display and then wont select it anyways (See image attached). When i try to detect the monitor in windows control > displays it detects the 3rd display but wont let me save dipslay settings to it or even activate the display. It tells me to use another combination of displays for setup (or something like that)

 

I hooked up the left monitor to DVI, switched the input to DVI and it works fine. So 2 out of my 3 VG248QE displays wont work on Displayport. Is this a Coincedence or do I have 2 defective monitors at the same time with the same issue of bad displayport?

 

I've tried on setup on my second PC which is a Asus Z77 platform running 3570k and 8gigs of ram.

but just built a new system on the Z79 platform using all new parts and i'm still having the same problem.

 

 

 

Entire System Specs:

 

- Windows 8.1 Pro 64bit

- Case: Fractal Node 605

- Corsair TX750 Power Supply

- EVGA GTX 980 SC with updated drivers.

- Asus Maximus Formula VII ROG Motherboard

- 2x BeQuiet 80mm 2000rpm Fans

- 1x Fractal Silent R2 Fan

- 3x Asus VG248QE Display

- 1x Asus PA248Q Display

 

System is not currently overclocked, and idle temp at 1000rpm  is 38deg Celcius and Aaida64 temps are around 60deg  at full fan speed.

 

 

Sorry if I rambled, I tried to stay on topic as per "Read before asking for help" post. I hope it's an easy fix and i'm just missing something. I really don't want to send all my monitors back to Asus for RMA's.

 

Thank you for your help
