INTRODUCTION
The InFocus LP400™ is specifically designed for the mobile pre-
senter. It packs SVGA graphics with 16.7 million colors into a
small, 6.8 pound package. It generates crisp, clear images using
Digital Light Processing™ (DLP) technology. The LP400 is easy to
connect, easy to use, and easy to maintain.
NOTE: The 400 automatically
expands 640x480 images to
800x600. You can display these
images at 640x480 by turning off
the Auto Resize feature. See “Auto
Resize” on page 21 for more infor-
mation.
Image Resolution
The SVGA resolution of the 400’s projected image is 800x600.
Screen resolutions between 800x600 and 1024x768 are com-
pressed to 800x600. The 400 cannot compress screen resolutions
above 1024x768. If your computer’s screen resolution is higher
than 1024x768, reset it to a lower resolution before you connect
the projector.
Compatibility
The projector is compatible with a wide variety of computers and
video devices, including:

Connecting a Video Player
1If your video player uses a round, one-prong 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 con-
nector, 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 40.)
2Plug the A/V cable’s yellow connector into the “video-out”
port on your video player (Figure 7). 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 8).
