    The projector supports projection and output of HDMI video and audio output from a computer or 
    video device.
    Important!Turn off the projector and the computer or video device before connecting them.
    zYou will need to obtain a commercially available HDMI cable with a connector that matches the 
    terminal of the output device on one end and a connector that matches the projector’s HDMI port 
    (HDMI Type A Socket) on the other end.
    zFor information about HDMI video signal supported by the projector, see page 54.
    zThe projector supports L-PCM 32kHz, 44.1kHz, and 48kHz HDMI audio signals.

    The projector is able to project images from the composite video output or component video output of 
    a connected video device.
    Important!Always turn off the projector and the video device before connecting them.
    Connection to a composite video output
    zYou can use the bundled special AV cable to connect to a pin jack (RCA) type video output terminal. 
    When connecting a video camera or other video device with a special video output terminal, use the 
    special cable that comes with the video device. For details, see the documentation that comes with 
    the video device.
    Connection to a component video output
    zComponent video output terminals come in 3-terminal sets: Y·Cb·Cr or Y·Pb·Pr. Be sure to match 
    the colors of the plugs on a component video cable with the colors of the terminals (Green: Y; 
    Blue: Cb/Pb; Red: Cr/Pr).
    zNote that connection only to an analog component video output terminal is supported.
    Connection to a digital output terminal is not supported.

    Operation During Projection
    Turning on the projector initially causes the same input source that was selected the last time it was 
    turned off to be selected.
    To select a different input source
    1.Press the [INPUT] key.
    zThis displays the input source selection screen.
    2.Use the [T] and [S] keys to select the name of the input source you want to 
    select and then press the [ENTER] key.
    zThe name of the input source you select appears in the upper right corner of the projection 
    screen for a few seconds.
    zThe message “No signal input.” will appear if no input signal can be selected.
    Resolution
    Depending on the projector model, its video resolution will be fixed at XGA (1024 × 768 pixels) or 
    WXGA (1280 × 800 pixels). Images may appear coarse, text and other figures may be difficult to read 
    or a moire pattern may appear when the input signal from a computer does not match the projector’s 
    video resolution. If this happens, try doing the following.
    zChange the computer’s output resolution setting so it matches the projector’s video resolution.
    For information about the video resolution of your projector, see the “DLP chip” item of the 
    “Specifications” (page 55). See the user documentation that comes with your computer for details 
    about changing its settings.
    zChange the “Aspect Ratio” setting to “True” (Applies only to models that support WXGA video 
    resolution).
    With the “True” setting, the projector projects the input signal at its actual size (1 input source dot 
    equal to one projector output pixel dot).
    For information about configuring the Aspect Ratio setting, see “Changing the Aspect Ratio of the 
    Projected Image” (page 19).

    You can perform the following operations while projecting an image.
    zImage brightness adjustment
    zManual keystone correction
    zColor mode selection
    zImage zooming
    zMomentarily blanking the image and muting the audio
    zImage freeze
    zPointer display in the projected image
    zAspect ratio switching
    Adjusting Image Brightness
    Note(for USB port model users)
    Use the setup menu (page 25) to adjust image brightness when the input source is an external 
    device connected to the USB port or via the wireless adapter.
    1.Press the [BRIGHT] key.
    zThis displays the brightness adjustment window.
    2.Use the [W] and [X] keys to adjust image brightness.
    3.To hide the window, press the [ESC] key.
    To use manual keystone correction
    The projector has a keystone correction feature that prevents 
    distortion of the projected image when projecting from an 
    angle. The projector detects when it is at a vertical angle to the 
    screen and performs keystone correction automatically.
    You can use the [KEYSTONE +] and [KEYSTONE –] keys to 
    adjust keystone correction manually.

    Displaying a Pointer in the Projected Image
    You can select from among different pointer styles, including various arrow styles, for display in the 
    projected image. Pointers can be used during a presentation to indicate or highlight a specific part of 
    the image.
    NoteDepending on the pointer style you are using, the pointer may not display properly when you are 
    using keystone correction. If this happens, use the [KEYSTONE +] and [KEYSTONE –] keys to 
    change the keystone correction value to zero.
