EnglishConnecting Video source devices
You can connect your projector to various Video source devices that provide any one of the 
following output sockets:
• HDMI
• DVI-I
• Component Video
•S-Video
• Video (composite)
You need only connect the projector to a Vide o source device using just one of the above 
connecting methods, however each provides a di fferent 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 HDMI source devices on page 23  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 DVI-I. If your source device is 
equipped with a DVI-I socket, you  can enjoy digital video quality.
See  Connecting DVI-I source devices on page 24  for how to connect the projector to a 
DVI-I source device and other details.
If no DVI-I source is available, the next best  video signal is Component Video (not to be 
confused with composite Vi deo). Digital TV tuners and DVD players output Component 
Video natively, so if available on your devi ces, they should be your connection method of 
choice in preference to S-Video or (composite) Video.
See  Connecting Component Video source devices on page 25  for how to connect the 
projector to a Component Video device.
Better video quality
The S-Video method provides a better quality an alog 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.
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 S-Video source devices on page 26  for how to connect the projector to an 
S-Video or Video device.
Connecting Audio
The projector has built-in mono speakers  which are designed to provide basic audio 
functionality accompanying data presentations for business purposes only. They are not 
designed for, nor intended for stereo audio repr oduction use as might be expected in home 
theater or home cinema applicat ions. Any stereo audio input (if provided), is mixed into a 
common mono audio output thro ugh the projector speakers. 
						

							Connection 23
EnglishConnecting HDMI source devices
The projector provides a HDMI input socket that allows y ou to connect it to a HDMI source 
device like a DVD player, a  DTV tuner or a display.
HDMI (High-Definition Multimedia Inte rface) supports uncompressed video data 
transmission between compatible devices like  DTV tuners, DVD players and displays over 
a single cable. It provides pure digita l viewing and listening experience.
Examine your Video source device to determ ine if it has a set of unused HDMI 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 an HDMI source device:
1. Take a HDMI cable and connect one end to  the HDMI output socket of the HDMI 
source device. Connect the other end of the  cable to the HDMI signal input socket on 
the projector. Once connected, the audio can be controlled by the projector On-Screen 
Display (OSD) menus. See  Audio Settings on page 51  for details.
2. Connect the other end of the HDMI  cable to the socket on the projector.
The final connection path should be like  that shown in the following diagram:
• In the unlikely event that you connect the projector to a DVD player and the projected 
picture displays wrong colors, please change the color space to YUV. See  Changing 
Color Space on page 33  for details.
• If no signal is detected after establishing the connection, turn off the Quick Auto Search  function in the SOURCE menu. See  Switching input signal on page 33  for details.
