Microsoft Office PowerPoint provides a feature you can use to show the presentation slides on a projector while keeping the Presenter view (with the speaker notes) on your notebook computer’s screen. To use this feature, you need to change your display settings. Here’s how:
-
Open the Display Properties dialog box by right-clicking the desktop and then clicking Properties.
-
Click the Settings tab.
-
Click the Secondary Display symbol (the 2).
-
Under the Screen resolution heading, select the Extend my Windows desktop onto this monitor check box. This setting gives you a desktop that spreads across both the projector and your notebook computer’s screen.

You can now set up PowerPoint to use both screens.
-
Open your presentation.
-
On the menu bar, click Slide Show, and then click Set Up Slide Show.
-
In the Set Up Show dialog box, locate the Multiple monitors option, and select the Show Presenter View check box.
-
Start the slide show. The Slide Show view of the presentation appears on the projector’s screen, while the Presenter view and speaker notes appear only on your notebook computer’s screen.
