What is Aspect Ratio?
Aspect ratio is the ratio of the image width to image height. Depending on your source, you will want to choose the aspect ratio (using your projector remote or keypad) which matches your source.
Older TV screens and laptops are 4:3; newer TV screens, HDTV and most DVDs are 16:9; and widescreen computers are 16:10.
Use an aspect ratio of 16:9 for widescreen movies and HDTV, and use Native for 4:3 content. Force Wide can also be enabled to automatically resize less common aspect ratios to 16:10.
