INTRODUCTION
The In Focus LP 425™ 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 LP 425 is easy 
to connect, easy to use, and easy to maintain.
NOTE: The 425 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 20 for more infor-
mation.
Image Resolution
The SVGA resolution of the 425’s projected image is 800x600. 
Screen resolutions between 800x600 and 1024x768 are com-
pressed to 800x600. The 425 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 425
.

video devices, including:

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 compo-
nents. 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 temper-
ature before use.
 This projector is not intended for use in mainframe computer 
rooms as defined in the Standard for the Protection of Electronic Com-
puter/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 35.
