2x GTX 1080 8GB in SLi
Win10 64
Water Cooled
Samsung 500GB m2
Cosair 16GB RAM

Display
1x Acer Monitor
3x Epson Projector output - 1920x1200

Thanks in advance!

Finally, solved it myself! Just posting what worked for me if it helps anyone else.
  1. I uninstalled GPU software incl. drivers
  2. Uninstalled all GPU controlling softwares - Afterburner/Nvdia inspector
  3. GPU in default mode
  4. Restarted PC
  5. Went to Nvdia site and downloaded the latest GPU driver for the respective cards (No Geforce experience/Nvdia Control Panel)
  6. Installed the drivers and restarted the pc
  7. Scaled back the graphics in P3d to high settings from Ultra and voila—it worked!
Hope this helps someone.
