What happened to my main monitor?

I was messing around with the ShadowPlay program in the GeForce Experience app. When I flipped on the switch to start ShadowPlay, my main monitor went black and my small throw away monitor came on, displaying everything. I cannot for the life of me get my main monitor to come back, as it seems the monitor is in sleep mode I guess. I have listed below some of my system stats from Belarc. I have tried uninstalling and then reinstalling the gpu driver, that did nothing. Any help would be greatly, greatly appreciated. Thanks.

Windows 8.1 Professional with Media Center (x64) (build 9600)
Board: Gigabyte Technology Co., Ltd. Z68XP-UD3P
3.30 gigahertz Intel Core i5-2500K
16302 Megabytes Usable Installed Memory
NVIDIA GeForce GTX 770 [Display adapter] (2x)

 

I checked out a handful of other boards including the GeForce support forum and the issue appears to involve a bug in the drivers rather than anything hardware related. Plenty of people with precisely the same experience as you, using both mono and dual-monitor setups. Only solution seems to be to uninstall the software.
