What is Aspect Ratio?

Aspect ratio is the ratio of the image width to image height. HDTV and most DVDs

are 16:9, which is the default for this projector. When in 4:3 mode the projector

places black bars on both sides of the image. Native mode centers the image and

turns off the internal scaler so that any resolution larger than the native projector

resolution is cropped on the edges. Letterbox expands the image to fill the screen.

Natural Wide stretches a 4:3 image to fill the entire 16:9 screen. The center two-

thirds of the image is unchanged; the edges of the image are stretched.

What you plan to project will also help you choose

between 4:3 and 16:9. For

example, most 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 anamorphic movies and

HDTV, and Native for 4:3 content. If you have a 4:3 screen you should still use 16:9

for anamorphic movies or HDTV, but you also have the option of using 4:3, Native,

or Natural Wide for 4:3 content. Force Wide can also be enabled to automatically

resize less common aspect ratios to 16:10.
