What is Aspect Ratio?

Aspect ratio is the ratio of the image width to image height. Standard TV

screens and older laptops are 4:3; HDTV and most DVDs are 16:9; and

widescreen computers are 16:10. If you are projecting onto a screen, the

size/shape of the screen will influence the aspect ratio you decide to use. If

you are projecting onto a blank wall, there are no screen size restrictions.

What you plan to project will also help you choose between 4:3, 16:9 or

16:10. Many TV shows are 4:3, while most movies are 16:9.

If you have a 16:9 screen then you should select an aspect ratio of 16:9 for

wid

escreen movies or HDTV, and Native for 4:3 content. If you have a 4:3

screen you should still use 16:9 for widescreen movies or HDTV, but you

also have the option of using either 4:3 (to fill the screen) or Native (for

direct pixel mapping) for 4:3 content. Force Wide can also be enabled to

automatically resize less common aspect ratios to 16:10.
