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 25 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 one of the HDMI connectors (HDMI 1 or HDMI 2) 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, connect one end of an RCA 
Component cable to the component video output connectors of the Video source 
device. Plug the other end of the RCA Component cable to the Y Cb/Pb Cr/Pr 
connectors on the projector.
You may use an optional Component to VGA adapter. 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 PC audio jack, connect a 3.5mm stereo cable to the Audio 1 or 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. For RCA audio jack, connect a 
RCA stereo cable to the Audio/L and Audio/R connectors on the projector and to 
your source. (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 30 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 blue for 1 minute 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 blue and the fans stop. If the Power Saving Mode feature 
is off and when the lamp has cooled, the LED blinks blue 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
