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. This is suitable for the
incoming image which is neither in
4:3 nor 16:9 and you want to make
most use of the screen without
altering the image's aspect ratio.

2. Real: The image is projected as its
original resolution, and resized to fit
within the display area. For input
signals with lower resolutions, the
projected image will display smaller
than if resized to full screen. You
could adjust the zoom setting or
move the projector away from the
screen to increase the image size if
necessary. You may also need to
refocus the projector after making
these adjustments.
