Slideshows in PowerPoint display with notes and extra areas since I received my new computer. How do I turn that off?
The version of PowerPoint in Office 2011 detects a projector or monitor as an additional display. When more than one display device is detected, slide shows may display in Presenter View - displaying the previous, current and next slides in a sidebar as well as an area for notes on one of the displays.
If you would like to turn this feature off, select Slideshow on the ribbon above the slides.
Select the Setting for Two Displays tab and click on the option to Mirror Show.
