INTRODUCTION
The InFocus® LP™425z and LP435z lightweight multimedia pro-
jectors are specifically designed for the mobile presenter. They 
generate crisp, clear images using Digital Light Processing™ 
(DLP) technology. The projectors are easy to connect, easy to use, 
and easy to maintain. The soft carry case makes it easy to trans-
port the 7.4 pound projectors. The 425z has SVGA 800x600 graph-
ics, the 435z has XGA 1024x768 graphics. The user interfaces of 
the two products are identical; information in this User’s Guide 
applies to both products.
Image Resolution
LP425z
The SVGA resolution of the 425z’s projected image is 800x600. 
Screen resolutions between 800x600 and 1024x768 are com-
pressed to 800x600. The 425z 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.
LP435z
The XGA resolution of the 435z’s projected image is 1024x768.

it to a lower resolution before you connect the projector.
NOTE: The 425z 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 28.
NOTE: The 435z automatically 
expands 640x480 and 800x600 
images to 1024x768. You can dis-
play these images at their original 
resolutions by turning off the Auto 
Resize feature. See “Auto Resize”
