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 or its vertical height.
This is suitable when you want to make most use of the screen
without altering the image's aspect ratio.
2. 16:9: Scales an image so that it is displayed in the center of the
screen with a 16:9 aspect ratio. This is most suitable for
images which are already in a 16:9 aspect, like high definition
TV and 16:9 aspect DVD movies, as it displays them without
aspect alteration.
3. 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 towards the screen to increase the image
size if necessary. You may also need to refocus the projector
after making these adjustments.
4. 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.
5. Full: Scales an image to full screen size (16:10). The image is
projected to fit all over screen. (EW331U-ST only)
