Get BigBox to launch on my primary display

[SiriusVI]

So here is the situation,

I mainly play games on my TV in the living room. However, sometimes, my girlfriend wants to watch TV and I have to retreat to my office and play games there. So I go to my office, launch BigBox and.... it launches on the TV, because that's what I'd told it to do when I last played in the living room. The problem is that I cannot access the option to change the monitor BigBox uses to my Display in my office, because BigBox is only visible on the TV screen. So I have to go to the living room, change the screen there, interrupt my girlfriend watching her show in the process, and then finally I can go to back to playing games.

Needless to say, this is not ideal. So my question is this: is there any way to make BigBox launch on what is set to be my primary display in windows? Kind of what RetroArch lets me do when I set the option to "auto"?

Thanks for your help, everyone.

Sounds like what you have is similar to mine.  Basically your PC set to dual monitors.  The PC and the TV.

Here's what I did to solve this issue.  

Granted there may be an easier way and they're always be a different way.  But this one I know works.

Basically the link shows how to easily switch between single and dual monitors.  I've since set mine up where I created a popup menu ("Joe's Monitor Menu") and select the monitor configuration for starting BigBox.  Keeping BigBox always on the "primary" monitor.
