Multiple monitors DETECTED, but not DISPLAYING! Help, please!

New to the community, so if this is posted in the wrong place, I apologize!

I recently upgraded to Win10 from Win7. Previously, I was using 3 monitors with no issues, but after the upgrade I can only display 2 monitors. All 3 are detected and I can extend display to any TWO of them, but not ALL three. I have 2 VGA ports, 1 DVI, and 1 HDMI and I can display any 2 monitors, but just not all of them at once. What could be the problem? I've tried uninstalling and reinstalling drivers, checked my BIOS, tried extending to all 3 through AMD Catalyst Control. I also swapped my HDMI monitor to a VGA and I'm still only able to display any 2 but not all 3. I'm at a loss here. 


-AMD Radeon HD 6700 Series


-AMD FX(tm)-4130 Quad-Core Processor

-Windows 10

-BIOS Version

Any help or suggestions would be appreciated!
