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 not in 4:3 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 backwards
the screen to increase the image size if
necessary. You may also need to refocus the
projector after making these adjustments.

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 aspect DVD movies, as it displays them
without aspect alteration.

4. 16:10: Scales an image so that it is displayed in
the center of the screen with a 16:10 aspect
ratio. This is most suitable for images which
are already in a 16:10 aspect as it displays them
without aspect alteration.

ratio. This is most suitable for images which

without aspect alteration.
