Make your presentation widescreen (16×9) in Microsoft PowerPoint
More and more presentations are being displayed in a widescreen format (16×9) on flatscreen HD TVs or new projectors. If you have a presentation that you already created in Microsoft PowerPoint, you can easily change it to a widescreen format.
In Microsoft PowerPoint, go to Design, Slide size and select widescreen. This will convert your presentation to widescreen and it will look great on an HD TV.
