Connecting a HDMI source device
The projector provides a HDMI input jack that allows you to connect it to a HDMI source 
device like a DVD player, a DTV tuner or a display.
HDMI (High-Definition Multimedia Interface) supports uncompressed video data 
transmission between compatible devices like DTV tuners, DVD players and displays over a 
single cable. It provides pure digital viewing and listening experience.
Examine your Video source device to determine if it has a set of unused HDMI output 
jacks available:
• If so, you can continue with this procedure.
• If not, you will need to reassess which method you can use to connect to the device.
To connect the projector to a HDMI source device:
1. Take a HDMI cable and connect one end to the HDMI output jack of the HDMI 
source device. Connect the other end of the cable to the HDMI signal input jack on 
the projector. Once connected, the audio can be controlled by the projector On-
Screen Display (OSD) menus. See Audio Settings on page 56 for details..
2. Connect the other end of the HDMI cable to the HDMI jack on the projector.
• If the selected video image is not displayed after the projector is turned on and the correct 
video source has been selected, check that the Video source device is turned on and 
operating correctly. Also check that the signal cables have been connected correctly.
• In the unlikely event that you connect the projector to a DVD player via the projectors 
HDMI input and the projected picture displays wrong colors, please change the color space 
to YUV. See Changing Color Space on page 32 for details.

Connecting a Component Video source device
Examine your Video source device to determine if it has a set of unused Component Video 
output jacks available: 
• If so, you can continue with this procedure.
• If not, you will need to reassess which method you can use to connect to the device.
To connect the projector to a Component Video source device:
1. Take a Component Video to VGA (D-Sub) adaptor cable and connect the end with 3 
RCA type connectors to the Component Video output jacks of the Video source 
device. Match the color of the plugs to the color of the jacks; green to green, blue to 
blue, and red to red.
2. Connect the other end of the Component Video to VGA (D-Sub) adaptor cable 
(with a D-Sub type connector) to the COMPUTER IN-1 or COMPUTER IN-2 
jack on the projector.
3. If you wish to make use of the projector speaker(s) in your presentations, take a 
suitable audio cable and connect one end of the cable to the audio output jack of the 
device, and the other end to the AUDIO jack of the projector.
• If the selected video image is not displayed after the projector is turned on and the correct 
video source has been selected, check that the Video source device is turned on and 
operating correctly. Also check that the signal cables have been connected correctly. 
						

							Connection 23
Connecting an S-Video/composite source device
Examine your Video source device to determine if it has an unused S-Video/composite 
output jack available: 
• If it has both jacks, use the S-Video output jack for connection as the S-Video terminal 
provides better picture quality than the Video terminal.
• If it has either of the output jack, you can also continue with this procedure.
• If not, you will need to reassess which method you can use to connect to the device.
To connect the projector to an S-Video/Video source device:
1. Take an S-Video/Video cable and connect one end to the S-Video/Video output jack 
of the Video source device.
2. Connect the other end of the S-Video/Video cable to theS-Video/ Video jack on 
the projector.
3. If you wish to make use of the projector speaker(s) in your presentations, take a 
suitable audio cable and connect one end of the cable to the audio output jack of the 
device, and the other end to the AUDIO jack of the projector.
• If the selected video image is not displayed after the projector is turned on and the correct 
video source has been selected, check that the Video source device is turned on and 
operating correctly. Also check that the signal cables have been connected correctly.
