PowerPoint 2013 now uses Presenter View by default in dual-display computers. To turn off Presenter View, follow these steps before running the presentation.
- On the ribbon (top menu bar), please select the SLIDE SHOW tab.
- In the Monitors group on the right, please uncheck the box for Use Presenter View.
- On the Monitor drop-down menu, change the selection from Automatic to Primary Monitor.
You may then continue your presentation just as you would normally.
