Using the Projector 17
Selecting the Aspect Ratio
The aspect ratio is the ratio between an image’s length and its height.
Standard images have an aspect ratio of 4:3; HDTV and almost all
DVD images have an aspect ratio of 16:9. If your video source is 16:9,
the projector displays it in its native ratio. If it is 4:3, you can choose
the best mode for projecting it.
Normal mode
4:3 image on input source displayed through projector
Normal mode maintains the aspect ratio
of the image source and the images are
projected onto a 16:9 screen area. When
4:3 images are being projected, black
bands appear on the sides.
Squeeze mode
16:9 image displayed in
squeeze mode on a 4:3
TV screen
displayed through projector
Use this setting if the video source has a
16:9 output mode. If images in squeeze
mode are viewed on a 4:3 TV screen, the
images are compressed (as shown on the
left). But when squeeze mode is selected
on the projector, the images are projected
correctly in their native wide-screen (16:9)
format.

When images output in 4:3 format are
projected using the projector’s squeeze
mode, they are elongated horizontally.
