If the image is still outstretched, you will also need to adjust the aspect
ratio by referring to the following: (See page 18)
 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

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 “Changing the Lamp”. See
page 28.
