Displaying an image
Touch the Power button on the keypad or the remote.
The Power button blinks green and the fans start to run. When the lamp 
turns on, the start up screen will display and the Power button will become 
solid green. It can take a minute for the image to achieve full brightness.
No start up screen? Get help on page 15.
Slide the lens cover to the side, if it is covering the lens.
Turn on your computer or video device.
The image should appear on the projection screen. If it doesn’t, press the 
Source button on the projector’s keypad or remote.
If you are using a VGA cable to connect your computer to the projector (instead 
of DisplayLink):
If using a laptop, make sure its external video port is active.
Many laptops do not automatically turn on their external video port when a 
projector is connected. Usually a key combination like Fn + F8 or CRT/LCD 
key turns the external display on and off. Locate a function key labeled 
CRT/LCD or a function key with a monitor symbol. Press Fn and the 
labeled function key simultaneously. Refer to your laptop’s documentation 
for more information about your laptop’s key combination or go to the 
InFocus website at: http://www.infocus.com/Support/LaptopActivation.aspx. 
No laptop image? Try pressing the Auto Image button on the keypad.
Is your laptop connected to the projectors DisplayLink connector? See the 
InFocus DisplayLink Software Users Guide (available on the InFocus 
website at www.infocus.com/displaylink) for troubleshooting information.

Position the projector to the desired distance from the screen at a 90 degree 
angle to the screen. See 
page 6 for a table listing to screen sizes and 
distances.
Adjust the zoom or focus.

Connecting a video device
You can connect video devices such as VCRs, DVD players, camcorders, 
digital cameras, video game consoles, HDTV receivers, and TV tuners to the 
projector. You can connect the audio directly to the projector to get sound 
from the built-in speaker, or you can bypass the projector’s audio system 
and connect the audio directly from your source to a stereo or home theater 
system.
You can connect the projector to most video devices that can output video. 
You cannot directly connect the coaxial cable that enters your house from a 
cable or satellite company; the signal must pass through a tuner first. 
Examples of tuners are digital cable boxes, VCRs, digital video recorders, 
and satellite TV boxes. Basically, any device that can change channels is 
considered a tuner.
Although the aspect ratio is automatically selected by the projector based on 
the signal input, you can change the aspect ratio, if desired. The projector’s 
Aspect Ratio setting is accessed through the Resize button on the remote or 
through the projector’s Basic Picture Menu. See 
page 27 for more 
information.
Video device connections
No video cables are provided with the projector. You can order cables from 
InFocus or use your own.
HDMI 1.3 connection
HDMI is a standard, uncompressed, all-digital audio/video interface. 
HDMI provides an interface between sources, such as set-top boxes, DVD 
players, and receivers and your projector. Plug an HDMI cable into the 
video out connector on the video device and into the HDMI connector on the 
projector.
To take advantage of HDMI 1.3 Deep Color (30 bit) you must have a 1.3-
compatible source.
Composite video connection
Plug the composite video cable’s yellow connector into the video out 
connector on the video device. Plug the other yellow connector into the 
yellow Composite connector on the projector.
Plug the white connector of a Mini-plug audio Y-cable into the left audio 
out connector on the video device and plug the red connector into the right 
audio out connector on the video device. Plug the other end of the cable into 
the associated audio in connector on the projector.
Keep in mind that video output from composite connections is not as high 
quality as S-video.
S-video connection
If your video device uses a round, four-prong S-video connector, plug an S-
video cable into the S-video connector on your video device and into the S-
video connector on the projector. Use the audio cable as described above.
Keep in mind that video output from S-video connections is not as high 
quality as component.
VGA connection
If your video device has a 15-pin VGA output, plug one end of the included 
computer cable into the VGA connector on your video source. This 
connector may be labeled “To Monitor” on the video source. Plug the 
computer cable into the VGA 1 or VGA 2 connector on the projector.
Component video connection
A Component to VGA adapter can be used in conjunction with the VGA 
connectors. Plug the component cable into the video device. Plug the other 
end of the component cable into the adapter and plug the adapter into the 
VGA 1 or VGA 2 connector.
Component offers the highest quality analog video output.

What is Aspect Ratio?
Aspect ratio is the ratio of the image width to image height. Standard TV 
screens and older laptops are 4:3; HDTV and most DVDs are 16:9; and 
widescreen computers are 16:10. If you are projecting onto a screen, the 
size/shape of the screen will influence the aspect ratio you decide to use. If 
you are projecting onto a blank wall, there are no screen size restrictions. 
What you plan to project will also help you choose between 4:3, 16:9 or 
16:10. Many TV shows are 4:3, while most movies are 16:9.
If you have a 16:9 screen then you should select an aspect ratio of 16:9 for 
widescreen movies or HDTV, and Native for 4:3 content. If you have a 4:3 
screen you should still use 16:9 for widescreen movies or HDTV, but you 
also have the option of using either 4:3 (to fill the screen) or Native (for 
direct pixel mapping) for 4:3 content. Force Wide can also be enabled to 
automatically resize less common aspect ratios to 16:10.

You can make the black screen appear after a preset number of minutes by
