How do I change my PowerPoint presentation from standard to widescreen?
PowerPoint 2010 and earlier has a default (standard) screen size of 4:3. PowerPoint 2013 changed that to make the default (widescreen) screen size 16:9. In PowerPoint, you can change the aspect ratio of your slides at any time. Keep in mind that everything in your presentation slides will change size and look distorted. If your presentation is 4:3 and you change it to 16:9, everything will be stretched wider. Read More: https://presentationpro.com/
