Monitor Configuration Not Working after Win10 Updates

So Win10 did its thing a couple days ago and updated itself for about 15 mins w/o being asked...

Anyway, I have 3 monitors, and now only 2 will work at a time....When all 3 monitors are plugged in, only monitors "A" and "C" will work...when I unplug "C", then A and B work, same with B and C...Any ideas on what caused this? It worked fine before windows updates, and nothing else changed since.

Have you updated your graphics drivers?

Yea, I was on the latest stable driver...Tried the beta to see if that did anything, ended up rolling back to the stable release again
