    Connecting Video source devices
    This section describes how to connect the projector to Video source devices using video 
    cables. Video cable connections are recommended for Video presentations. 
    You can connect your projector to various Video source devices that provide any one of the 
    following output sockets:
    •DVI
    •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 DVI. If your source device is equipped with a 
    DVI socket, based on the type of DVI connector you have, you can enjoy digital or high-end 
    analog video quality.
    See Connecting a DVI source device on page 22 for how to connect the projector to a DVI 
    source device and other details.
    If no DVI source is available, the next best video signal is Component Video (not to be 
    confused with composite Video). Digital TV tuners and DVD players output Component 
    Video natively, so if available on your devices, they should be your connection method of 
    choice in preference to S-Video or (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.

    Connecting a DVI source device
    The projector provides a DVI input socket that allows you to connect it to a DVI source 
    device like a DVD player, or a VGA output device like a notebook or desktop computer.
    There are three types of DVI connectors: DVI-A, DVI-D, and DVI-I. The DVI-I socket is an 
    integrated connector which supports both formats: DVI-A, and DVI-D. 
    DVI-A format is used to carry a DVI signal to an analog (VGA) display, or vice-versa. 
    Although some signal quality is lost from the signal conversion, it still transmits higher 
    picture quality than a standard VGA connection. 
    DVI-D format is used to directly carry a digital signal to a digital display without signal 
    conversion. The pure digital connection provides faster and higher image quality than an 
    analog connection, due to the nature of the digital format. 
    DVI-A and DVI-D formats are non-interchangeable. You cannot connect a DVI-A format 
    connector to DVI-D equipment and visa-versa. Make sure you know which kind of format 
    your equipment is fitted with before you purchase any cables. Or you can purchase a DVI-I 
    cable which will be more useful in any type of DVI connection situation.
    Examine your source device to determine if it has an unused DVI 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 a DVI source device or a computer:
    For information on connecting a DVI source device to a computer through a VGA to DVI-A 
    cable, see Connecting a computer on page 18. 
    1. Take a DVI (DVI-D or DVI-I) cable and connect one end to the DVI output socket of 
    the DVI source device.
    2. Connect the other end of the cable to the DVI signal input socket on the projector. 
    3. If you wish to make use the projector (mixed mono) speaker, take a suitable audio 
    cable and connect one end of the cable to the audio output sockets of the video device, 
    and the other end to the AUDIO socket of 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.

    In the unlikely event that you connect the projector to a DVD player via the projector’s DVI-D 
    input and the projected picture displays wrong colors, please change the color space to YUV. 
    See Changing Color Space on page 31 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 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.
    Once connected, the audio can be controlled by the projector On-Screen Display 
    (OSD) menus. See Audio Settings on page 51 for details.
    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 21 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 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 21 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 21 for details.
