Hello, I have 2 monitors, but only need the 2nd one when I am live streaming. I was wondering how to disable it without unplugging it everytime, because I assume running 2 monitors even with nothing on the 2nd one, will make my FPS drop a little bit.
The easiest way is to use the Windows key + p
a small window pops up in the middle of your desktop screen. Select the first option computer only. This will shut down the second monitor and only the main monitor will be active.
