Extending displays means that your computer interprets the monitors, projectors, and/or screens that you are extending the image to as separate devices. You can set it up to see different things on each monitor, and your same desktop background is displayed on each screen.
Click the link below to jump to the section.
You can adjust the display settings to use two or more scenes as separate displays. When used as a separate display, PowerPoint and Keynote presentations will display Presenter Notes to the computer, but not to the external display (projector).
Computer only – is the default option – only displays on the main (or a single) monitor.
Extend – makes all of your monitors act like one big monitor extending the desktop across all of them.
Duplicate – makes all of the monitors display the same thing by duplicating the desktop on each monitor.
Projector only – Displays only on the secondary monitor like a projector.
Note: The duplicate or mirror display setting is typically the default when connected to external displays.
