Dual Monitor weirdness


So I have dual GEForce GTX 1080 cards on a Hardware bridge. The left Monitor will flash on for a few seconds and then goes black. IF I run
Code:
nvidia-detect 
Detected NVIDIA GPUs:
01:00.0 VGA compatible controller [0300]: NVIDIA Corporation GP104 [GeForce GTX 1080] [10de:1b80] (rev a1)
02:00.0 VGA compatible controller [0300]: NVIDIA Corporation GP104 [GeForce GTX 1080] [10de:1b80] (rev a1)

Checking card:  NVIDIA Corporation GP104 [GeForce GTX 1080] (rev a1)
Your card is supported by the default drivers.
It is recommended to install the
    nvidia-driver
package.

How do I get dual monitors working?

Hi, check out this appendix from the nVidia website...

Code:
https://download.nvidia.com/XFree86/Linux-x86_64/430.14/README.html
Option "SLI" "string"
Option "nvidiaXineramaInfoOverride" "string"

see links at the bottom...

Chapter 22. Using the X Composite Extension
Chapter 29. Configuring SLI and Multi-GPU FrameRendering
I hope this helps.
