Displaying an image
Touch the Power button.
The Power button blinks green and the fans start to run. When the lamp 
comes on, the start up screen displays and the Power button is steady green. 
It can take a minute for the image to achieve full brightness.
? No start up screen? Get help on page 15.
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 VESA 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 to learn your laptop’s key combination.
? No laptop image? Try pressing the Auto Image button on the 
keypad. Get help on 
page 15.
? Is your laptop connected to the projectors DisplayLink 
connector? See the InFocus DisplayLink Manager Users Guide for 
troubleshooting information.

Adjusting the image
If necessary, adjust the height of the projector by pressing the elevator foot 
release button to extend the foot.
If necessary, rotate the leveling foot located at the rear of the projector.
Avoid placing your hands near the hot exhaust vent at the side of the 
projector.
Position the projector the desired distance from the screen at a 90 degree 
angle to the screen.
See page 5 for a table listing screen sizes and distances.
Adjust the zoom or focus.
If the image is not square, first make sure that the projector is perpendicular 
to the screen. If the image is larger or smaller on the top or bottom edge of 
the screen, press the top Keystone button to reduce the upper part of the 
image, and press the bottom Keystone button to reduce the lower part.
If the left or right side of the screen is larger or smaller the other, you can 
turn the projector to the left or to the right a few degrees to square the 
image.
Adjust the Contrast or Brightness in the Basic Picture menu. See page 28 for 
help with these menu adjustments.
For Aspect Ratio, keep in mind that DVD players must be configured for 
16:9 in order to view the highest quality image. For more information 
regarding Aspect Ratio, see 
page 12.

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.
Before connecting your projector, you should decide which aspect ratio you 
want to use. 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 28 for more information.
What is Aspect Ratio?
Aspect ratio is the ratio of the image width to image height. TV screens are 
usually 4:3. HDTV and most DVDs are 16:9. If you’re projecting onto a 
screen, the size/shape of the screen may determine which aspect ratio to 
use. If you are projecting onto a blank wall, you don’t have the screen size 
restriction. What you plan to project will also help you choose between 4:3 
and 16:9. Most 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 
anamorphic movies or HDTV, and Native for 4:3 content. If you have a 4:3 
screen you should still use 16:9 for anamorphic 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. Keep in mind that anamorphic movies 
only appear correctly if the DVD player is set to output to a 16:9 television.

Video device connections
No video cables are provided with the projector. You can order cables from 
InFocus or provide your own.
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 Video 3 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 Audio In Video connector on the projector.
Keep in mind that video output from composite connections is not as high 
quality as S-video.
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.
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 
Video 2 connector on the projector. Use the audio cable as described above.
Keep in mind that S-video delivers higher quality video output than 
composite.
VESA 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 Computer 3 or Computer 2 connector on the 
projector.
Component video connection
If your HD video device has component connectors, an optional 
Component to VESA adapter can be used. 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 Computer 3 or Computer 2 connector. 
Component offers the highest quality video output.

Shutting down the projector
The projector automatically displays a black screen after no active source is 
detected for 30 minutes. This black screen helps preserve the life of the 
projector. The image returns when an active source is detected or a remote 
or keypad button is pressed.
Screen Save Time
You can make the black screen appear after a preset number of minutes by 
turning on the Screen Save Time feature in the Setup menu. See 
page 30.
Auto Off Time
The projector also has an Auto Off Time feature that automatically turns the 
projector off after no active sources are detected and no user interaction 
with the projector is performed for 30 minutes. By default, this feature is off. 
You can change the length of time, see 
page 30.
Turning off the projector
To turn the projector off, press the Power button on the remote or keypad. 
The lamp turns off and the LED blinks amber for 1 minute while the fans 
continue to run to cool the lamp. When the lamp has cooled, the LED lights 
amber and the fans stop. Unplug the power cable to completely power off 
the projector.
Troubleshooting your setup
If your image appears correctly on the screen, skip to the next section. If it 
does not, troubleshoot the setup.
The Status Indicator Panel on top of the projector indicates the state of the 
projector and can help you troubleshoot
