Connecting to a Video Source
Caution :
When connecting the projector to other video sources, take the following precautions.
 Turn off the power for both the projector and the video source before connecting them. 
If the power for either device is on at the time of connection, damage may result.
 Check the shapes of the cable connectors and the device ports before making the 
connections. If you try to force a connector to fit a device port with a different shape or 
number of terminals, a malfunction or damage to the connector or port may result.
Projecting Composite Video Images
 Use the accessory A/V cable (red/white/yellow) to connect the video source 
to the Video and Audio 2 ports at the rear of the projector.
 If the audio output port of the video source is a stereo mini jack, use a 
commercially-available audio cable to connect the video source to the Audio 
1 port at the rear of the projector.
Tip :
After making the connections, change the Audio Input setting in the Audio menu to 
either Audio1, Audio2 or USB, depending on which input port you are using. The 
default setting is Audio2.

the accessory A/V cable (red/white) to connect the video source to the Audio 
2 port at the rear of the projector. Alternatively, use a commercially-available 
audio cable to connect the video source to the Audio 1 port at the rear of the 
projector. Use either method depending on the shape of the video source’s 
audio output port and on the type of cable you have.
Tip :
After making the connections, change the Audio Input setting in the Audio menu to 
either Audio1, Audio2 or USB, depending on which input port you are using. The

Projecting RGB Video Images
RGB video is used when RGB signals that have copy protection added are input 
and projected.
 Use the accessory computer cable to connect the video source to the 
Computer 2/Component Video port at the rear of the projector. Alternatively, 
use the optional DVI analog cable to connect the video source to the 
Computer 1 port at the rear of the projector. 
See “ Appendix: Optional Accessories” (P.100)

Tip :
 RGB video is only compatible with sync-on-green signals. This can be checked by 
looking at SYNC Mode in the About menu.
 After making the connections, change the Comp1 Input or Comp2 /YCbCr Input 
setting in the Setting menu to RGB Video.
For separate sync (separate H-SYNC and V-SYNC) signals, set to Analog-RGB. 
(P.69) This can be checked by looking at SYNC Mode in the About menu.
 After making the connections, change the Audio Input setting in the Audio menu to 
either Audio1, Audio2 or USB, depending on which input port you are using. The 
default setting is Audio2.

Connecting to an External Speaker
You can connect the projectors Audio Out port to speakers with a built-in 
amplifier in order to enjoy even fuller sound.
Use a commercially-available audio cable with pin jack ⇔ stereo mini jack 3.5 
mm (0.14 inches) plugs or similar.
Use an audio cable with a connector that matches the port for the audio 
equipment.
Tip :
If a stereo mini jack is connected to the Audio Out port, the sound will be externally 
output, and will stop coming out from the projectors built-in speaker.

6If more than one signal source has 
been connected, use the remote 
control or control panel buttons to 
select the port which the signal 
source that you would like to use is 
connected to, while referring to the 
following table.
Tip :
 If only one signal source has been connected, the signals from that source will be 
projected without needing to press one of the above buttons.
 If the No-Signal. message does not disappear, check the connections again.
 If a laptop computer or a computer with a LCD screen has been connected to the 
projector, the images may not be projected straight away. After making the 
connections, check that the computer has been set up to output signals. 
The following table shows examples of how to toggle output settings. For details, refer 
to the section of the documentation provided with your computer under a heading such 
as External output, Connecting an external monitor or similar.
 If the same still picture is projected for a long period of time, the projected image may 
become burned in on the computer screen. You should avoid leaving the same image 
displayed for long periods.Po r tButton to press
