Nvidia Surround stuck in dual

[Rosco71]

Hey everybody, I need some help with my triple monitor setup.

I have three 1920 x 1080 monitors with one being 3D in the middle. I switch between 3D in 1920 x 1080 and 2D in 5760 x 1080 using the Nvidia control panel.
All of a sudden when I go to switch to surround it says that I can only choose two monitors??? By all accounts all three are connected and working! Got me stumped...
I have two GTX 770's in SLI in a MSI Z87-GD65

Many thanks for a solution in advance, missing my racing

Try using Control Panel, Display Settings.

Try using Control Panel, Display Settings.

Where abouts? Display; gives you resolution options only, and Device Manager; everything working.

It will allow you to connect 3 monitors.
