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 Menu. See 
page 24 for more 
information.
Video device connections
No video cables are provided with the projector. You can order cables from 
InFocus or provide your own.
HDMI 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.
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 
connector on the projector.
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 
either the Computer 1 or Computer 2 connector on the projector.
Component video connection
If your HD video device has component connectors, an optional Component to 
VGA 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 1 or Computer 2 connector.
S-video connection
Plug the S-video cable’s connector into the video-out connector on the video 
device. Plug the other connector into the S-Video connector on the projector.
Audio
For audio, connect a 3.5mm stereo cable to the Audio 1/Audio 2 connector on the 
projector and to your source. If your source uses RCA audio connectors, a Y-cable 
or adapter may be used. (Note: A separate audio connection is not required for 
HDMI source inputs.)

Shutting down the projector
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 20 minutes. By default, this feature is off. You can 
change the length of time, see 
page 27.
Turning off the projector
To turn the projector off, press the Power button on the remote or keypad. The 
lamp turns off and the Power LED blinks amber for 30 seconds while the fans 
continue to run to cool the lamp. If the Power Saving Mode feature is on and when 
the lamp has cooled, the LED lights amber and the fans stop. If the Power Saving 
Mode feature is off and when the lamp has cooled, the LED blinks green 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 Lights on top of the projector indicate the operational state of 
the projector and can help you with troubleshooting.
