Problem: The image is outstretched when displaying
16:9 DVD.
The projector automatically detects 16:9 DVD and adjusts the
aspect ratio by digitizing to full screen with 4:3 default setting.
If the image is still outstretched, you will also need to adjust the
aspect ratio by referring to the following:
 Please select 4:3 aspect ratio type on your DVD player if you are
playing a 16:9 DVD.
 If you can’t select 4:3 aspect ratio type on your DVD player, please
select 4:3 aspect ratio in the on screen menu.
Problem: Image is reversed.

Select “Image” from the OSD and adjust the projection direction.
See page 24, 25.
