This article covers how to manage multiple screens on Macintosh and Windows.

Windows

On Windows, you can use the keyboard shortcut (Windows Key + P) to bring up the display picker that gives you the option to select one of the following display modes:

Computer/PC screen only - The second screen is ignored and only the PC’s primary display is used.
Duplicate - The second screen mirrors the primary display.
Extend - The PC display is extended across all screens.
Projector/Second screen only - The main PC display will be disabled and only the secondary screen is used.

Macintosh

On Macintosh, you can use the keyboard shortcut Command + F1 to mirror or extend your displays. To configure more advanced multiple-display options, consult this Apple support article.

You can also find in Settings and under Displays an Arrange multiple displays setting that can provide more customization options with your displays.
