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 width and vertical height.
This is suitable for the incoming image
which is in 4:3 or 16:9 and you want to
make most use of the screen without
altering the image’s aspect ratio.
2. 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.
3. 4:3:
Scales an image so that it is displayed
in the center of the screen with a 4:3
aspect ratio. This is most suitable for
4:3 images like computer monitors,
standard definition TV and 4:3 images
aspect DVD movies, as it displays
them without aspect alteration.
4. Letter Box:
Scales an image so that the original
aspect ratio of the production is
preserved. For input signals that do
not conform to the projector's native
resolution, the full unaltered image is
displayed with a black border where
no image exists.
