Rig
1) i5-6600k
2) EVGA GTX980 TI
3) 32 GB memory
4) SSD + HDD
5) W10
 
Putting aside I run 3 ASUS monitor surround (G-Sync) and a 4th aux monitor, the centre DCP port on the GPU causes the monitor to flicker periodically.
I have used different monitors and different ports, and therefore, it appears to be the centre DCP outlet that is the issue.
With reference to the NVIDIA Control Panel:
1) Change Resolution - 3* 2560/1440/60hz
2) Desktop size position - it has a mind of its own !!!!!!!!!!!!!!!!!!!!!
 
any ideas appreciated

Hello,
 
does this issue occur when you only connect one display to the center DP port? Meaning the other 3 displays are not connected to the card?
 
Please let us know.

Sorry guys not to sure how to push forum buttons
Yes have tried different cable
Yes the monitor continues to  flickers with all other monitors/cables disconnected.
This problem has only recently occurred. I have had issues setting up G-Sync monitor surround in the past
 

Flickering monitor from the centre outlet
I have deactivated the K boost mode (1200MV) back to default of 1025MV. (EVGA Precession XOC)
I still have GPU Clock at 75 and the MEM Clock at 100MHZ
 
The flickering monitor problem has stopped. I will continue to monitor the issue
 
All constructive thoughts appreciated

X-Plane is not a game its aviation. I can tolerate the 20/25fps

UPDATE FLICKERING MONITOR
problem not solved monitor occasionally flickers on but mostly off
W10 was professionally clean installed
Therefore  problem is either the card or its software
Recapping GTX 980 TI 3*ASUS 27 inch monitor surround (G-Sync)
 
Any ideas appreciated
