    Connecting a monitor
    If you want to view your presentation close-up on a monitor as well as on the screen, you 
    can connect the RGB signal output socket on the projector to an external monitor with a 
    VGA cable following the instructions below:
    1. Connect the projector to a computer as described in Connecting a computer on page 
    20.
    2. Take a suitable VGA cable (only one supplied) and connect one end of the cable to the 
    D-Sub input socket of the video monitor.
    3. Connect the other end of the cable to the D-SUB OUT socket on the projector.
    The final connection path should be like that shown in the following diagram:
    The D-Sub output only works when an appropriate D-Sub input is made to the projector.

    Connecting Video source devices
    You can connect your projector to various Video source devices that provide any one of the 
    following output sockets:
    • 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 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 23 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 24 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 25 for how to connect the 
    projector to a composite Video device.
    Connecting Audio
    The projector has a 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 theatre or 
    home cinema applications. Any stereo audio input (if provided), is mixed into a common 
    mono audio output through the projector speaker. 
    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. 
    The audio connections illustrated in the following sections are provided for informational 
    purposes only. You need not connect audio to the projector if there is an alternate sound 
    system available, or if audio is not required. 
    						
    							Connection 23
    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 Component Video to VGA (D-Sub) 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 Component Video to VGA (D-Sub) adaptor cable (with 
    a D-Sub type connector) to the D-SUB/COMP IN socket on the projector.
    3. If you wish to make use of the projector (mixed mono) speaker, take a suitable audio 
    cable and connect one end of the cable to the audio output socket of the computer, 
    and the other end to the Audio socket of the projector.
    The final connection path should be like that shown in the following diagram:
    If you connect the projector to a High Definition TV (HDTV) tuner, the follow ing standards 
    are supported:
    • The projector is only capable of playing mixed mono audio, even if a stereo audio input is 
    connected. See Connecting Audio on page 22 for details.
    • Component Video is the only video output that delivers native 16:9 aspect ratio picture.
    • 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 final connection path should be like that shown in the following diagram:
    • The projector is only capable of playing mixed mono audio, even if a stereo audio input is 
    connected. See Connecting Audio on page 22 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 22 for details.
