About the aspect ratio In the pictures below, the black portions are inactive areas and the white portions are active areas. OSD menus can be displayed on those unused black areas. 1. Auto: Scales an image proportionally to fit the projector's native resolution in its horizontal or vertical width. This is suitable for the incoming image which is neither in 4:3 nor 16:9 and you want to make most use of the screen without altering the image's aspect ratio. 4:3 picture 16:9 picture 2. 4:3: Scales a picture so that it is displayed in the center of the screen with a 4:3 aspect ratio. This is most suitable for 4:3 pictures like computer monitors, standard definition TV and 4:3 aspect 4:3 picture DVD movies, as it displays them without aspect alteration. 3. 16:9: Scales an image so that it is displayed in the center of the screen with a 16:9 aspect ratio. This is most suitable for images which are already in a 16:9 aspect, like high definition TV, 16:9 picture as it displays them without aspect alteration. 4. Wide: Stretches the picture horizontally in a non- linear manner, that is, the edges of the picture are stretched more than the center of the picture to prevent distortion of the central part of the 4:3 picture picture. This is suitable for occasions where you want to stretch the width of a 4:3 aspect picture to the width of a 16:9 aspect screen. It does not alter the height. Some widescreen movies have been produced with their width squashed down to the width of a 4:3 aspect, and are best viewed when restretched back to their original width using this setting. 5. Letter Box (LB): Scales a picture to fit the projector's native resolution in its horizontal width and resize the picture's height to the 3/4 of the projection width. This may produce a picture 16:9 picture greater in height than can be displayed, so part of the picture is lost (not displayed) along the top and bottom edges of the projection.

About the aspect ratio
In the pictures below, the black portions are inactive areas and the white portions
are active areas. OSD menus can be displayed on those unused black areas.
1.
Auto
: Scales an image proportionally to fit the
projector's native resolution in its horizontal or
vertical width. This is suitable for the incoming
image which is neither in 4:3 nor 16:9 and you
want to make most use of the screen without
altering the image's aspect ratio.
2.
4:3
: Scales a picture so that it is displayed in the
center of the screen with a 4:3 aspect ratio. This is
most suitable for 4:3 pictures like computer
monitors, standard definition TV and 4:3 aspect
DVD movies, as it displays them without aspect
alteration.
3.
16:9
: Scales an image so that it is displayed in
the center of the screen with a 16:9 aspect ratio.
This is most suitable for images which are
already in a 16:9 aspect, like high definition TV,
as it displays them without aspect alteration.
4.
Wide: Stretches the picture horizontally in a non-
linear manner, that is, the edges of the picture are
stretched more than the center of the picture to
prevent distortion of the central part of the
picture. This is suitable for occasions where you
want to stretch the width of a 4:3 aspect picture to the width of a 16:9 aspect screen.
It does not alter the height. Some widescreen movies have been produced with their
width squashed down to the width of a 4:3 aspect, and are best viewed when
restretched back to their original width using this setting.
5.
Letter Box
(LB)
: Scales a picture to fit the
projector’s native resolution in its horizontal width
and resize the picture’s height to the 3/4 of the
projection width. This may produce a picture
greater in height than can be displayed, so part of
the picture is lost (not displayed) along the top and
bottom edges of the projection. This is suitable for
the display of movies which are presented in letter
box format (with black bars on the top and
bottom).
