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.
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:
• IBM-compatible computers, including laptops, up to 1024x768 
resolution.
• Apple Macintosh and PowerBook computers up to 1024x768 
resolution.
• Most standard VCRs, DVD players, camcorders and laser disc 
players.
Unpacking the Projector
The projector comes with the items shown in Figure 1. Check to 
make sure all are included. Contact your InFocus dealer imme-
diately if anything is missing.
If you are experienced in setting up presentation systems, use the 
Quick Start card that was included in the shipping box. For com-
plete details on connecting and operating the projector, refer to 
this User’s Guide. User’s Guides are also available for download 
from our website at www.infocus.com.
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.
NOTE: The 400 ships standard 
with computer and audio cables. If 
you want to control your com-
puter’s mouse from the projector, 
you must order the optional 
CableWizard and remote.

Usage Guidelines
•  Do not look directly into the projection lens when the projector 
is turned on. The bright light may harm your eyes.
•  Do not block the grills on the projector. Restricting the air flow 
can cause it to overheat and turn off. If this happens, you must 
wait a minute before attempting to turn it back on.
•  Handle the projector as you would any product with glass 
components. Be especially careful not to drop it.
•  Avoid leaving the projector in direct sunlight or extreme cold 
for extended periods of time. If this happens, allow it to reach 
room temperature before use.
•  This projector is not intended for use in mainframe computer 
rooms as defined in the Standard for the Protection of Elec-
tronic Computer/Data Processing Equipment, ANSI/NFPA 75.
•  Transport the projector in a vendor-approved hard or soft case. 
Part numbers for these cases are listed on page 40.
