English

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, as it displays them without aspect alteration.

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

4.Letter Box:

Scales an image so that the original aspect ratio of the production is preserved. For input signals that do not conform to the projector's native resolution, the full unaltered image is displayed with a black border where no image exists.

5.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 away from the screen to increase the image size if necessary. You may also need to refocus the projector after making these

adjustments.

OSD menus can be displayed in the unused black areas.
