About the aspect ratio
1. Anamorphic (ANA): Scales an image so that it is displayed in
the center of the screen with a 16:9 aspect ratio. This setting
stretches and resizes linearly, except that it treats the vertical
and horizontal dimensions independently. It stretches the
height of the source image until it reaches the full projected
height, and stretches the width of the source image until it
reaches the full projected width. 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.
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. 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 centre of the
projection. This is most suitable for use with PC and RGBHD
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.
