    Broadcast Key 
    Enter a checkmark if you want keypad commands sent to one projector to be relayed 
    to all projectors in a serial network. Note that the 
    Proj key will temporarily “override” 
    the effect of a broadcast setting and allow you to control a specific projector when 
    necessary. Disable the setting for all but one (any) projector in a network.

    Front IR / Back IR 
    As needed for your application, set to “any” so that the front and/or rear IR sensor 
    locations on the projector respond to the IR keypad. Set to “off” to disable. 
    To disable both IR sensors, you cannot use the IR remote keypad to select the second 
    OFF setting. This safeguard prevents accidentally disabling an IR keypad while you 
    are using it. Instead, use either the built-in keypad or a wired remote (optional) to set

    the remaining active sensor to OFF. The projector will no longer respond to an IR 
    remote keypad.  
    NOTE: Protocols B – G are used for rental staging applications. 
    Wired Keypad 
    The wired keypad is ON by default to when connected to the rear of the projector. The 
    projector will then respond to incoming commands from this port. To disable the 
    wired keypad, you must use a different keypad—the built-in or an IR remote 
    keypad—to select “off”. This safeguard prevents you from accidentally disabling the 
    wired keypad during use. 
    In the Configuration menu, select the 
    Geometry and Color submenu when 
    you need to modify overall color 
    performance and/or image geometry 
    for all sources. 
    Test Pattern 
    Choose the desired internal test 
    pattern, or select OFF to turn off a test 
    pattern. Alternatively, use the 
    Te s t 
    key for cycling through test patterns. 
    Keystone 
    NOTE: If the optional ChristieTWIST module is installed, this option is Keystone and 
    Warping, and activates a submenu for defining custom image shapes. Please refer to 
    documentation included with your Christie TWIST module. 
    Use to correct a keystoned image shape in which both sides of your image are inclined 
    toward the top or bottom edge. Tilting the projector in relation to the screen typically 
    causes keystone; the lens surface and screen are no longer parallel to each other.

    Brightness Uniformity 
    — SUBMENU 
    Brightness Uniformity provides further refinement of displays already matched for 
    their primary colors and overall light output. Use Brightness Uniformity to create an 
    exceptionally smooth image in which no area appears brighter and/or more red, green 
    or blue than another. In the Brightness Uniformity menu, enable the “Uniformity 
    Enable” checkbox to access a multitude of adjustments for critical color light output 
    control in specific areas throughout the image. Your settings apply as long as the 
    “Uniformity Enable” checkbox is enabled and you are using a “User” color 
    temperature defined by the Brightness Uniformity controls. To disable the Brightness 
    Uniformity function, delete the “Uniformity Enable” checkmark.    System Configuration

    procedure for achieving uniform brightness in adjacent displays. 2) If Christie TWIST 
    module is installed, the enable checkbox changes to a list giving the option to choose 
    from several different uniformity maps. Please refer to documentation included with 
    your Christie TWIST module. 
    Edge Blending 
    — SUBMENU 
    The Edge Blending submenu provides a range of controls for smoothing together the 
    overlapping bright edges of multiple adjacent projected images to create a single 
    larger “seamless” image. These controls, which primarily affect white levels, are 
    typically used in conjunction with mechanical lens blinders (optional), which are 
    installed on the front of the projector and which primarily affect black levels. There is 
    a centerline (both horizontal and vertical) in the Edge Blending test pattern. The 
    intersection of these lines is the true center of the projector’s display area. 
    NOTES: 1) There is a centerline (both horizontal and vertical) in the Edge Blending 
    test pattern. The intersection of these lines is the true center of the projector’s display 
    area. 2) See also 3.10, Using Multiple Projectors.  
    Color Adjustments by X/Y, and Color Saturation — 
    SUBMENUS 
    NOTES: 1) For defining or changing a User 1, 2, 3, or 4 color performance or 
    “gamut”. Sometimes known as Comprehensive Color Adjustment™.  2) Factory-
    defined primary color levels, which ensure a specific color performance from 
    projector-to-projector, can be calibrated in the Service menu only. If you suspect 
    alteration of these defaults, the factory settings can be recovered with selection of 
    “Reset to Factory Defaults?” in the Color Primary Settings submenu accessed via 
    the Service menu (password-protected). 
    From the factory, the projector can utilize 
    any of the three pre-defined color 
    performance settings identified at right 
    (default=Max Drives), or colors can be 
    driven on the basis of color temperature. 
    For most applications, one of these gamuts 
    will produce accurate and realistic colors 
    from a variety of sources. They can be 
    applied at any time in the Advanced Image 
    Settings menu (“Select Color 
    Adjustment”), and are not adjustable. 
    DEFINING “USER” COLOR GAMUTS: In some cases, you may find that none of the pre-
    defined “Select Color Adjustment” options exactly suit your needs. For example, you 
    may require a unique color gamut (range) for a single projector or application, or you 
    may need to precisely match colors across multiple adjacent displays. In such cases, 
    use the Color Adjustments by X,Y or Color Saturation submenu to define the precise 
    hue of each primary color component (red, green, blue, and white) used to generate 
    the millions of colors produced in displays. You can create up to four custom color 
    gamuts (User 1, 2, 3, or 4) with these adjustments. 
    Note that the two menus differ only in their user interface, so use whichever menu 
    best suits your needs and application. A color meter can help with adjustments.

    • Color Adjustments by X,Y — Enter known x/y coordinates from the chromaticity 
    graph. 
    • Color Saturation
     — Adjust color slide bars and judge image color by eye or 
    meter. 
    A user-defined color “adjustment” can be applied by selecting it in the Advanced 
    Image Settings menu (“Select Color Adjustment”). 
    COLOR ADJUSTMENT BY X,Y: Use 
    this submenu if you want to create, 
    alter or copy a color gamut (i.e., 
    “color adjustment”). Controls in 
    this menu define the precise hue of 
    each primary color component (red, 
    green, blue, and white) used to 
    generate the millions of colors 
    produced in displays. The x/y 
    coordinates for each color define its 
    location on the standard CIE 
    chromaticity graph (see Figure 
    3.9)—changing either or both of 
    these numbers will change the hue 
    of the color, and relocate the 
    “triangle” for possible colors. For 
    example, changing the x/y 
    coordinates for red may move the 
    color closer to orange or closer to violet, which will in turn affect all displayed colors 
    having a red component. Adjust the slide bars or enter new specific coordinates as 
    desired to define or change up to four “User” color gamuts needed for your 
    environment and applications. Apply at any time in the Advanced Image Settings 
    menu.

    NOTE: Keep new x,y coordinates within the original color gamut triangle shown 
    here. 
    PROCEDURE FOR X,Y ADJUSTMENTS:  See 3.10, Using Multiple Projectors. 
    COLOR SATURATION: Use this submenu 
    if you do not have specific color 
    coordinates in mind and will simply 
    judge color performance by eye or 
    meter. Like the Color Adjustment by X,Y 
    submenu, each color control actually 
    defines new x/y coordinates for that 
    color and changes its hue—it is just a 
    different interface. 
    Adjust the hue of each primary color 
    (red, green, blue, and white) by using 
    more or less of it in relation to the other 
    colors. 
    NOTE: A Color Saturation adjustment defines the corresponding x/y coordinates 
    shown in the Color Adjustment by X,Y submenu. These x/y coordinates will remain 
    stable for this User gamut until they are changed again via either menu. Values 
    displayed in the Color Saturation menu, however, will likely fluctuate as you use the 
    projector, and will be different when you return to this menu at some point in the 
    future. These floating changes do not affect the x/y coordinates or gamut.

    Black Level Blending — SUBMENU 
    Black Level Blending is a feature that eliminates the differences between black levels 
    when edge blending multiple projectors. The Black Level Blending submenu provides 
    many controls to allow the edges of adjacent images to be smoothly overlapped 
    creating a “seamless” image. Edge blending smoothes white levels, and if edge 
    blending is not in use, Black Level Blending is disabled. Black Level Blending 
    provides a simple solution for uneven black levels, without the need for external 
    hardware, by matching up black level hues with a “target area” hue (the intersection of 
    the center lines), and adjusting the overlaps (edges) surrounding the target area.  
     
    NOTES: 1) Refer to section 3.10, Using Multiple Projectors for additional 
    information. 2) There is a centerline (both horizontal and vertical) in the Black Level 
    Blending test pattern. The intersection of these lines is the true center of the 
    projector’s display area. 3) Adjust white levels before adjusting black levels. 4) 
    Blinders are recommended for fixed installations. 
     
    Default Color Adjustments 
    — SUBMENU 
    Refer to System Configuration – Geometry and Color, Color Adjustments by X,Y for 
    description. 
    Intelligent Lens System (ILS
    ™) — SUBMENU 
    ILS™ provides the ability to recall focus and zoom settings specific to each source 
    input. Custom lens settings you’ve chosen for any source will be quickly and 
    accurately applied when you select a source that has already been calibrated. Place a 
    checkmark in the checkbox to enable ILS™. If no calibration has previously been 
    done you may be prompted to do a full calibration. If a motion calibration has been 
    done, you will be prompted to complete a reference calibration. If both calibrations 
    have been done, the checkbox will be checked and ILS™ enabled. If ILS™ is enabled, 
    a reference calibration will be done on power up and the lens will return to the saved 
    position of the source that is active at the time of power up or to the position the lens 
    was located when it was powered on. Further adjustments to the zoom, focus and 
    position will be automatically saved for source the selected source. If you switch to a 
    source with different lens settings and switch back, the lens will automatically move 
    to your saved settings upon return. Other sources can be used without using ILS™ . 
    NOTES: 1) See System Configuration – Diagnostics/Calibration, ILS Calibration 
    for further details about calibration. 2) ILS
    ™ control is a preference setting and will 
    be retained between power cycles. 
     
    Test Pattern 
    Choose the desired internal test pattern to 
    display, or select OFF to turn off a test 
    pattern. Alternatively, use the 
    Te s t key 
    for cycling through test patterns. 
    NOTE: There is a centerline (both 
    horizontal and vertical) in the Edge 
    Blending test pattern. The intersection of

    Test Pattern Grey Level 
    Set the desired level of grey for displaying in the full gray field test pattern. 
    Freeze Image 
    Enter a check mark to freeze (stop) an image on a single frame. This diagnostic tool is 
    useful if you need to examine in detail a still version of an incoming image that cannot 
    be “frozen” at the source. For example, in moving images it is sometimes difficult to 
    observe artifacts such as external de-interlacing/resizing and signal noise. Remove the 
    checkmark to return back to normal. 
    Color Enable 
    Select which color or colors you want to see. This is useful while working with color 
    temperature, input levels or other special setup parameters. Colors can also be 
    enabled/disabled by entering the corresponding function code listed on the back of the 
    standard remote keypad. 
    Odd Pixel Adjustment 
    NOTES: 1) Factory-set and rarely required by user. 2) Source must be >90 MHz. 
    When using certain RGB sources, you may need to adjust the normal gain or offset of 
    odd pixels in relation to even pixels. This will smooth out very narrow (one-pixel 
    wide) “checks” or vertical stripes that indicate adjacent “on” and “off” pixels. Using 
    the Level Detector simplifies this process (see Figure 3.11): 
    1. Use an external analog native-sized continuous grayscale test pattern with at least 
    256-levels. 
    2. Turn “Level Detector” on. 
    3. Set “Level Value” to ~200. The image should now be black-and-white (or black-
    and-one color, if you use “Color Enable” function). 
    4. Adjust offset. Half of the pixels will move, the other half will not. 
    5. Adjust until the two transition regions overlap. The stripe of noise will be 
    minimized, defined by the value in the slide bar. 
    6. Set “Level Value” to ~800. The image should now be black-and-white. 
    7. Repeat Steps 4 and 5, but adjusting gain. 
    8. Repeat Steps 3-7 for all remaining colors. Your RGB source should now be OK. 
    Two sets of values are automatically saved with these controls—one value for Input 
    #1, and one for Input #2 (analog). The current set of values depends on which source 
    is in use. This enables a source to be processed correctly via two different inputs.

    Figure 3.11. Using “Odd Pixel Adjustment” 
    NOTES: 1) Adjust offset before gain, since offset affects gain. 2) A value of 128 
    represents no change in normal odd pixel offset or gain. 3) Odd Pixel Adjustment 
    eliminates “one pixel on, one pixel off” artifact only, not any type of larger artifacts. 
    Reserved 
    No function. 
    Peak Detector 
    The “Peak Detector” is a fast method for defining individual input levels, and can 
    improve the accuracy of input levels set by the Auto Input Level function. Enabling 
    the “Peak Detector” activates a special operating mode for detecting only pixels that 
    are considered black or white—all other levels are displayed as a mid-level gray. 
    When used with a 16-step grayscale pattern in which the two black and white bands 
    are known to be at opposite edges of the image, you can watch these isolated areas 
    while adjusting individual black levels and input drives until both bands are just 
    visible. Images from this source will then display correct blacks and whites without 
    crushing or washing out. 
    NOTE: If using Peak Detector with PIP, both images must have the same color space. 
    Level Detector 
    The “Level Detector” checkbox enables specific thresholds for blacks and whites—
    input levels that fall below a specified Level Value (see below) are displayed as black, 
    and all others are displayed as white. It aids in Odd Pixel Adjustment. To use: 
    1. Enable “Level Detector” and display a continuous grayscale. 
    2. Set “Level Value” to near black (such as 200). 
    3. Adjust Offsets to minimize area of black stripe. 
    4. Set “Level Value” to near white (such as 800). 
    5. Adjust Gains to minimize area of white stripe. 
    Level Value 
    Level Value defines the value to be used by the Level Detector in recognizing blacks 
    and whites. See Level Detector, above.

    Aspect Ratio Overlay 
    Selecting this option with a checkmark will overlay a number of common aspect ratio 
    boxes on top of the source image. This is very helpful during the setup of the projector 
    and can be turned off after desired specifications have been achieved.  
    LiteLOC™ Calibration 
    NOTES: 1) LiteLOC™ Calibration takes up to two minutes. 2) For best results, allow 
    the projector to warm up for 15 minutes prior to calibration. 
    LiteLOC™ Calibration defines the range of power needed to maintain lamp 
    brightness. Select Calibrate LiteLOC for calibration using your projector’s unique 
    specifications (recommended) rather than standard specifications. The projector will 
    revert to the default back-up in the event of a power failure. 
    Intelligent Lens System (ILS
    ™) Calibration 
    This option allows you to choose between three types of lens calibrations. Reference 
    calibration determines a reference point that is used as a defined starting position for 
    relative motion of the lens. All positioning is measured from this reference point. A 
    reference calibration is lost when power is removed from the projector and will occur 
    on every power up as long as ILS™ is enabled. A motion calibration determines the 
    characteristics of each motor and values are saved in the projector’s memory. If ILS™ 
    is enabled and a motion calibration has previously been done, the projector will 
    automatically recall these settings from memory when it’s being powered up and a 
    motion calibration will not take place. A full calibration performs both a reference 
    and motion calibration. 
    Automatic ILS Lens Calibration 
    When this option is selected (default) and the projector is in ILS mode, the projector 
    will perform a lens calibration on each power-up. During calibration, the shutter will 
    be closed and the status LED will display ‘LC’. If ILS is not selected, the ALC setting 
    will be ignored. If, during power-up, ALC is not selected and ILS is, the last stored 
    location from the previous ILS calibration will be assumed to be true and the lens will 
    moved to that position upon power-up if necessary. 
    The two “Option Card” 
    entries In the 
    Configuration menu 
    identify which optional 
    input modules (a.k.a. 
    cards) are present at 
    INPUT 5 (Option 1) and 
    INPUT 6 (Option 2). If 
    either of these option 
    slots is empty, the corresponding read-only menu entry does nothing. If there is a 
    module installed, the corresponding menu entry may activate a submenu of further 
    options pertaining to that module. 
    For example, if the Dual SD/HD-SDI module is installed at 
    INPUT 5 (Option 1). The 
    Option 1 Card submenu provides controls for configuring the various connections on 
    this multi-input, multi-output module. As desired for your application, you can define 
    1) which physical input loops through to which output, and 2) which functional input 
    (main or PIP signal) loops through to which output.

    PIP (Picture-in-Picture) and Seamless Switching are independent but related projector 
    features that both utilize two image-processing paths within the projector. In the case 
    of Picture-in-Picture, this double processing enables you to display two different 
    images simultaneously – typically a smaller “secondary” image within a large 
    “primary” background.  In a seamless switch, the double processing essentially occurs 
    between displays so that a full image relayed from one source can smoothly transform 
    into a full image from another source. This change can be virtually instantaneous, or 
    slowed as desired so that the current image appears to dissolve or “fade” into the new 
    image. 
    Options for enabling and controlling PIP and Seamless Switching all reside in the 
    same menu. Note, however, that because both features utilize the projector’s double 
    processing capability, PIP and Seamless Switching cannot be used together. For 
    example, fading a pair of PIP images into a new display from a different source is not 
    possible. 
    For best PIP or Seamless Switching results, use two different signal types* as defined 
    below. Do not mix two signals of the same type. 
     Signal Type Description (Input Location) 
    #1  5 BNCs (RGBHV or YPbPr) 
    #2  DVI - I (analog or digital) 
    #3  Decoded signals (Input 3, Input 4, Composite video, S-Video, or any video 
    signal via  Input 1 BNC connectors or via an analog option card). 
    #4 Analog Option Cards 
    #5 Digital Option Cards 
    #6 Digital Option Cards 
    * HD interlaced sources are not recommended for the PIP window. 
    Other PIP or Seamless Switching tips to keep in mind include: 
    • When using two digital signals or one analog and one digital, each must be ≤ 165 
    megapixels.  
    • When using two analog signals, each must be ≤ 90 megapixels. 
    • Avoid using an interlaced source in the PIP window 
    • Seamless switching may affect image quality in some cases 
     
    NOTE: To control the primary image, access all picture controls through the Main 
    menu. To control the secondary (PIP) image, access picture controls through the 
    Picture-in-Picture and Switching menu. 
    Use the first of six 
    options in the PIP 
    and Switching menu 
    to enable and define 
    how you want to use 
    PIP.
