Mirroring screen on Windows 11 or Windows 10 can be done without any third party software. It’s a built-in Windows feature that allows you not only to duplicate but also to extend or to show only certain screen. There are two ways to access to this feature – by using shortcut key to quickly switch modes to duplicate, or by changing the multiple displays option in the Settings.

If this is not what you were looking for, try the following:

Options unavailable or monitor not detected

If you’re plugging in a new monitor or projector, make sure they are plugged correctly using the correct cable and connected to the correct port.

If there is any driver CD that comes with the hardware, make sure to also install it so that it can be detected and work with Windows properly.

Optionally, to manually detect a newly plugged monitor, projector or other types of displays, do the following.

Right-click anywhere on your desktop and select Display settings. Under rearrange your displays, click on Detect to tell Windows to detect any newly plugged display.

Main display accidentally switched to other display

If in any case the main display switched to a monitor, TV or projector that you do not wish to be the primary display, especially after switching back from “duplicate mode” which often causes the issue, you can change the main display back to your preferred monitor in the Display settings.
