How to Change Presentation Mode to Project Display in Windows 10


Display Switch is used to change the presentation mode of the main display of your Windows 10 PC to project on either the PC screen only, duplicate on second display, extend across all displays, or second screen only.

This tutorial will show you how to project the main display to PC screen only, duplicate, extend, or second screen only for all users in Windows 10.

Projection Mode Description
PC screen only Only the current main display is enabled. All other connected displays will be disabled. (When you're connected to a wireless projector, this option changes to Disconnect.)
Duplicate The main display will be mirrored on the second display.
Extend (default) The main display is extended across the all connected display screens and allows you to have a desktop that spans them.
Second screen only The current main display will be disabled. All other connected displays will remain enabled with the second screen used as your new main display.
