disable surround and select activate all displays in the nvidia control panel.
Then use the windows display options to arrange the monitors in the right order and set them each to 1920x1080 at 60hz 32bit color. Make sure they all hit the right resolution.
Now that your sure all your hardware is working go back to the nvidia control panel and enable surround. Skip the wizard and just leave it at 5670x1080. If that works you can run the wizard later for bezel correction and such.
