Change The Powerpoint view to 16:9 ratio
In PowerPoint you can adjust the 'Page Setup' commands to change the height and/or width of the page - changing the aspect ratio.
You can make it so that the effect on screen will look similaar to the letterbox films that you see on TV - with black space above and below the picture.
Choose 'File' menu, select 'Page Setup'.
Make the Width 64 cm and the Height 36 cm.
