Overview

With Windows, if you have N displays plugged in, Windows will always try to use all N displays.

However, in Dsplay Settings you can tell Windows to stop sending a video signal to specific displays.

If two displays are plugged in

Of only two displays are connected, and Windows gives you the option to "Show only on 1" or "Show only on 2"

If 3 or more displays are plugged in

In Windows 11, the options look a little different if you have 3 displays connected. Below 3 are connected, and they way to get Windows to stop using one of them now is to click Disconnect this display.

Once you've disconnected you can always reconnect the display by clicking on that button and selecting an extend or duplicate option.
