Connecting Video source devices
You can connect your projector to various Video source devices that provide any one of the 
following output sockets:
• HDMI
• Component Video
•S-Video
• Video (composite)
You need only connect the projector to a Video source device using just one of the above 
connecting methods, however each provides a different level of video quality. The method 
you choose will most likely depend upon the availability of matching terminals on both the 
projector and the Video source device as described below:
Best video quality
The best available video connection method is HDMI. If your source device is equipped 
with a HDMI socket, you can enjoy uncompressed digital video quality.
See Connecting an HDMI device on page 17 for how to connect the projector to a HDMI 
source device and other details.
If no HDMI source is available, the next best video signal is Component video (not to be 
confused with composite video). Digital TV tuner and DVD players output Component 
video natively, so if available on your devices, this should be your connection method of 
choice in preference to (composite) video.
See Connecting a Component Video source device on page 17 for how to connect the 
projector to a component video device.
Better video quality
The S-Video method provides a better quality analog video than standard composite Video. 
If you have both composite Video and S-Video output terminals on your Video source 
device, you should elect to use the S-Video option.
See Connecting an S-Video source device on page 18 for how to connect the projector to 
an S-Video device.
Least video quality
Composite Video is an analog video and will result in a perfectly acceptable, but less than 
optimal result from your projector, being the least video quality of the available methods 
described here.
See Connecting a composite Video source device on page 18 for how to connect the 
projector to a composite Video device.
Connecting audio
The projector has one built-in mono speaker which is designed to provide basic audio 
functionality accompanying data presentations for business purposes only. It is not designed 
for, nor intended for stereo audio reproduction use as might be expected in home theater or 
home cinema applications. Any stereo audio input (if provided), is mixed into a common 
mono audio output through the projector speaker. 
If you wish, you can make use of the projector (mixed mono) speaker in your presentations, 
and also connect separate amplified speakers to the Audio Out socket of the projector. The 
audio output is a mixed mono signal and controlled by the projector Volume and Mute 
settings. 
						

							 17
If you have a separate sound system, you will most likely want to connect the audio output 
of your Video source device to that sound system, instead of to the mono audio projector.
Connecting an HDMI device
You should use an HDMI cable when making connection between the projector and HDMI 
devices.
To connect the projector to an HDMI device:
1. Take an HDMI cable and connect one end to the HDMI output port of the video 
device.
2. Connect the other end of the cable to the HDMI input port on the projector. 
• In the unlikely event that you connect the projector to a DVD player via the projector’s 
HDMI input and the projected picture displays wrong colors, please change the color 
space to YUV. See Changing HDMI input settings on page 24 for details.
• The projector is only capable of playing mixed mono audio, even if a stereo audio input is 
connected. See Connecting audio on page 16 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 sockets 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 VGA (D-Sub)-Component adaptor cable and connect the end with 3 RCA type 
connectors to the Component Video output sockets of the Video source device. Match 
the color of the plugs to the color of the sockets; green to green, blue to blue, and red 
to red.
2. Connect the other end of the VGA (D-Sub)-Component adaptor cable (with a D-Sub 
type connector) to the COMPUTER IN 1 or COMPUTER IN 2 socket on the 
projector.
• The projector is only capable of playing mixed mono audio, even if a stereo audio input is 
connected. See Connecting audio on page 16 for details.
• 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.

Connecting an S-Video source device
Examine your Video source device to determine if it has an unused S-Video output socket 
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 an S-Video source device:
1. Take an S-Video cable and connect one end to the S-Video output socket of the Video 
source device.
2. Connect the other end of the S-Video cable to the S-VIDEO socket on the projector.
• The projector is only capable of playing mixed mono audio, even if a stereo audio input is 
connected. See Connecting audio on page 16 for details.
• 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.
• If you have already made a Component Video connection between the projector and this 
S-Video source device using Component Video connections, you need not connect to this 
device using an S-Video connection as this makes an unnecessary second connection of 
poorer picture quality. See Connecting Video source devices on page 16 for details.
Connecting a composite Video source device
Examine your Video source device to determine if it has a set of unused composite Video 
output sockets 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 composite Video source device:
1. Take a Video cable and connect one end to the composite Video output socket of the 
Video source device.
2. Connect the other end of the Video cable to the VIDEO socket on the projector.
• The projector is only capable of playing mixed mono audio, even if a stereo audio input is 
connected. See Connecting audio on page 16 for details.
• 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.
• You need only connect to this device using a composite Video connection if Component 
Video and S-Video inputs are unavailable for use. See Connecting Video source devices 
on page 16 for details.
