Bonus: Presenter View Mode

PowerPoint’s full-screen mode provides a distraction-free viewing experience to the audience. But as the presenter, you may want access to the notes simultaneously.

To solve this conundrum, PowerPoint offers its Presenter View mode. The feature lets you see your presentation content and notes on the device while your audience only sees the slides.

In other words, you (the presenter) see slide notes, the next slide, the timer, etc. The audience will be oblivious to all the information at your disposal.

The notes and extra information facilitate organization, a smooth flow, and access to reference points for things to say next or when on a particular slide.

It’s a more modern or well-designed version of PowerPoint’s “normal view” or “window mode.”

To present your slides in the Presenter View mode, here are the steps (Note: You’ll need two monitors for the job):

Step 1: Open your PowerPoint file and choose Slide Show from the options above. Next, choose Use Presenter View.

Step 2: Next, choose the screen for your presentation or set it as “Speaker View,” which is typically the Primary Monitor.

Step 3: Hit the Alt + F5 keys on the keyboard.

This setup will project the slide only on your projector screen. Your computer or laptop screen will showcase the data-rich layout, which includes speaker notes, following slide preview, etc.

 You should know your keyboard shortcuts well to truly excel at or extract the most out of the Presenter View mode.

The knowledge will make you appear more confident and professional since you’d not be clumsy with the mouse and moving through slides seamlessly.


A full-screen PowerPoint presentation is vital to deliver a distraction-free and impactful presentation.

Although the option to encompass the whole screen with the slide is a primary PowerPoint feature, it may not work as seamlessly at times.

Or you may be struggling to enable the full-view mode when dealing with multiple screens, such as a laptop and a projector screen.

If you’re stuck too, the above methods hopefully offer you the solution and help you seamlessly switch between slides and the various presentation modes.
