3. 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).

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.
