1. Auto: Proportional scaling of an image to t the
projector’s natural resolution in its horizontal
width. This is suitable where the incoming image
is neither in 4:3 nor 16:9 aspect ratios but where
you want to make most use of the screen without
altering the image’s aspect ratio.

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 such as those for
computer monitors, standard denition TV, and
4:3 aspect DVD movies as these can be displayed
without aspect alteration.
