If you want to project from behind a translucent screen, set
up the projector behind your screen. See “Rear Projection”
on page 32 to reverse the image.
•
If you are installing the projector on the ceiling, refer to the
LP750 Ceiling Mount Installation Guide
that comes with the
Ceiling Mount Kit for more information. To turn the image
upside down, see “Ceiling Projection” o n page 31. The Ceiling Mount Kit is sold separately; see page 50.
Position the projector the desired distance from the screen.

•
The distance from the lens of the projector to the screen
determines the size of the projected image. Figure 3 shows
three projected image sizes using the lens at maximum
zoom. For more information about image size, see “Projected Image Size” on page 56.
NO TE: An optional extension
cable, sold separately, lets you
increase the distance between the
projector and your computer to

Connecting a Video Player
If your video player uses a round, one-pr on g composite video

connector, you’ll need only the A/V cable that shipped with
the projector.
•
If your video player uses a round, four-prong S-video connector, you’ll need an S-video cable in addition to the A/V
cable. The S-video cable is sold separately. (See “Optional
Accessories” on page 50.)
Plug the A/V cable’s yellow connector into the “video-out”
2
port on your video player (Figure 11). This port may be
labeled “To Monitor.”
•
If you’re using an S-video cable, connect it to the “S-video
out” connector on the video player (Figure 12).
Plug the other yellow connector int o the composite connector

The projector is compatible with these major broadcast video
standards: NTSC, NTSC 4.43, PAL, PAL-M, PAL-N, and SECAM.
It automatically adjusts to optimize its performance for the
incoming video. The input signals for SECAM, PAL-M, and
PAL-N video cannot be automatically detected, therefore they
must be chosen manually; see “Video Standard” on page 31.
