Triple display. How to quickly turn off two and leave primary active?

Action center


Select project(you may need to turn it on in Settings>System>Notifications & actions>Quick actions>Add or remove quick actions)

Thanks Cliff S, that's awesome. The only bizarre thing now is that even though monitor 3 is listed as primary (assuming primary would tell windows that its the PC display), when I choose PC screen only, it goes to the right display which is not the one set as the primary display. I guess I can try setting it as PC display only and move outputs around on the video card until the middle display indeed is the primary display.

That might be a good idea,

Press the Windows Logo Key and the P key and you'll get the selection menu. For me the one that is set as primary is the one that stays on. The numbers don't denote which monitor is primary. You can set any one you want as primary regardless of what number it has. I have shortcuts on my taskbar for PC screen only and Extend.
C:\Windows\System32\DisplaySwitch.exe /internal < is PC screen only
C:\Windows\System32\DisplaySwitch.exe /extend < is Extend.
I switch to just my one main screen when gaming, then switch back my 3 screen setup when done.
