Windows 10: I accidentally set my monitor to not primary display

I accidentally pressed something and saw display settings for monitors, I only had one monitor but it showed two, and then I scrolled down and pressed something that made the monitor a secondary monitor accidentally because I was being dumb and it went pitch black. i heard the two monitor glitch is something like ghost monitors. and i have tests tomorrow!

How do I make games open on the primary display?

I have 3 monitors on a nvidia GTX660Ti, with the latest drivers, on windows 10, upgraded from win7, on a PC that I have been gaming on for quite some time now. The hardware itself has been an excellent gaming rig up until the windows upgrade and/or the
nvidia driver upgrade, but now a number of my games will not start on the primary display, they start on the first display in the list, which is not marked as primary. Both the windows display settings and the nvidia control panel have my central monitor
identified as the primary display.

• Has anybody encountered this behavior?
• Is it likely to be windows 10 related or decided by the nvidia driver?
• Any suggestions on getting this to behave properly, like it used to, without requiring me to disable the other displays to get the primary to be used?
