Operation
2.
Anamorphic: Scales a picture so that it is displayed
in the center of the screen using 1280 x 720 pixels.
This may alter the projected aspect, depending
upon the original aspect of the source image.
Anamorphic is most suitable for images which are
already in a 16:9 aspect, like high definition TV, as it
displays them without aspect alteration.
3.
Fill: Resizes the picture to the full projection area.
1280 x 768 pixel is used without maintaining the
original aspect ratio. This is most suitable for 15:9
pictures.
4.
Letter Box: 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. 1280 x 960 pixels are used in this projection.
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).
5.
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.
6.
Real: For input sources with lower resolutions than
1280 x 768, the projected picture will display
smaller than if resized to full screen.
If the input source is with higher resolution than
1280 x 768, the picture will be resized
proportionally until it fits the width or height of the
projection.
