Windowed mode spreads game but cannot do Nvidia 2D Surround

[DeadJohnDoe]

I have a 3-monitor setup, same size monitors, same refresh rate, same resolution. They are all hooked up to the same GPU, a Nvidia Gtx 650 ti boost. A game I play allows for windowed mode and if I put the game in this mode, I can stretch the game window to spread across all monitors, and run the game just fine. So I figure if I can do this, why can't I do it in fullscreen with Nvidia 2D surround? My MSI 970a G43 motherboard does not support SLI, but I assumed that was only a factor in multiple gpus... Any ideas why it may not work or how to troubleshoot it?

You need to set up surround in the nvidia control panel.
