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 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.
