Using the projector
English
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.
5. Real: This setting displays the image in a one-to-one pixel mapping
without alteration or resize in the center of the projection. This is most
suitable for use with PC source inputs.
The black portions are inactive areas and the white portions are active
areas.
OSD menus can be displayed on those unused black areas.
Using Panamorph lenses (optional)
Panamorph lenses allow you to convert 16:9 projectors to the full 2.35:1 aspect ratio of most motion
pictures, showing the best movies without letterbox bars at top and bottom of images while increasing
resolution by 33% and brightness by 20%.
You may need a 2.35:1 screen to display the 2.35:1 images. For more information, please go to
www.panamorph.com or contact the place you purchased the projector.
