Problem: The image is outstretched when displaying 16:9

If the image is still outstretched, you will also need to adjust the aspect
ratio by referring to the following:

4
select 4:3 aspect ratio in the on screen menu.
Problem: Image is reversed.
Select "Management" from the OSD and adjust the projection
4
direction. See page 25.
