If you're using PowerPoint 2013 or PowerPoint 2016, just connect the monitors and PowerPoint automatically sets up Presenter View for you. In Presenter view, you can see your notes as you present, while the audience sees only your slides.
At the bottom of the PowerPoint slide window, select Slide Show.
Tip: Now, if you are working with PowerPoint on a single monitor and you want to display Presenter view, in Slide Show view, on the control bar at the bottom left, select , and then Show Presenter View.
Use the controls in Presenter view
To move to the previous or next slide, select Previous or Next.
To view all the slides in your presentation, select See all slides.
Tip: You’ll see thumbnails of all the slides in your presentation (as shown below), making it easy to jump to a specific slide in the show.
To view a detail in your slide up close, select Zoom into slide, and then point to the part you want to see.
To point to or write on your slides as you present, select Pen and laser pointer tools.
Press the Esc key when you want to turn off the pen, laser pointer, or highlighter.
To hide or unhide the current slide in your presentation, select Black or unblack slide show.
