The image is stretched when displaying 6:9 DVD title
When you play anamorphic DVD or 6:9 DVD, the projector
will show the best image when the projector display mode is
set to 6:9 in the OSD.
If you play 4:3 format DVD titles, please change the format to
4:3 in the projector OSD.
If the image is still stretched, you will also need to adjust the
aspect ratio by referring to the following:
Please setup the display format as 6:9 (wide) aspect ratio
type on your DVD player.
Image is too small or too large
Move the projector closer to or further from the screen.
Press “Menu” on the projector panel or projector panel, go to
“Display  Format” and try the different settings.
Image has slanted sides
If possible, reposition the projector so that it is horizontally
centered on the screen and below the bottom of the screen.
Press “Keystone” button on the remote control, until the sides
are vertical.
Image is reversed
Select “SETUP  Projection” from the OSD and adjust the
projection direction.

If possible, turn off the projector, then unplug the power cord
and wait at least 60 seconds before reconnecting power.
Check that “Keypad Lock” is not activated by trying to control
the projector with the remote control.
Lamp burns out or makes a popping sound
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” section on pages 78-79.
