ratio by referring to the following:

Please select 16:9 aspect ratio type on your DVD player if you are
playing a 4:3 DVD.
If you can't select 16:9 aspect ratio type on your DVD player, please
select 16:9 aspect ratio on screen menu.
Select "Management" from the OSD and adjust the projection
direction. See page 24.
When the lamp reaches its end of life, it will burn out and may
make a loud popping sound. If this happens, the projector will
not turn on until the lamp module has been replaced. To replace
the lamp, follow the procedures in the "Replacing the Lamp".
