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

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.
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

alteration.
