    Figure 3.16. Match Zones to Center Color Temperature 
    Repeat the color adjustment of sides and corners for each edge of the screen that does 
    not yet match the center (note that each corner is adjustable in either of its two 
    adjacent “side” menus). When done, all areas of a given screen should match. Repeat 
    Steps 
    2a & 2b for all remaining screens. 
    Step 3: Adjust Light Output in Eight Zones 
    3a) For each screen, compare the light output of each edge and corner to that of the 
    center. If any of the areas differ, use the White Uniformity menu to match edges 
    and corners to the center as described below (see Figure 3.17). Begin with the 
    screen exhibiting the most obvious variations in light output. 
    • Adjust edge White Uniformity first—note that each edge adjustment also 
    affects the rest of the screen slightly. Keep all edges just slightly lower 
    than the center light output rather than matching light output precisely. 
    Otherwise, it may not be possible to brighten the corners (typically the 
    dimmest areas of the screen) enough. I.e., the best uniformity is a 
    compromise between the brightest and darkest areas of the screen. 
    • Adjust corner White Uniformity last—each corner adjustment affects only 
    this quadrant.  
    • Repeat for each screen.

    still exhibit a single color temperature.

    Cancelling Brightness Uniformity 
    If you do not want to use or apply Brightness Uniformity settings, delete the 
    checkmark from the “Uniformity Enable” checkbox at the top of the Brightness 
    Uniformity menu. 
    Christie Edge Blending is an innovative set of software functions that can quickly and 
    easily blend white levels along the edges of multiple adjacent projected images to 
    create a single seamless larger image. 
    What is a Blend? 
    In simple terms, a blend appears as a gradient strip 
    along an edge of a projected image. It is darkest along 
    the extreme edge of the image, and lightens nearer to 
    the rest of the image (see right). 
     
     
    How Are Blends Used? 
    In multiple-projector walls, complementary blends between neighboring images can 
    compensate for the extra “brightness” or intensity where these edges overlap. By 
    controlling blend width and other properties, you can achieve uniformity across the 
    group of images. Visible overlaps will disappear: 
     
    Figure 3.18. Edge Blending Concept 
    For best results, use the same projector model and type throughout your display wall. 
    In addition, avoid high-gain screens whenever possible—the optical performance of 
    such screens demands minimal image offset, thus projectors must be located very 
    close to one another. 
    Edge blending software controls are located in the two-page Edge Blending 
    submenu—access via Configuration menu, then go to the Geometry and Color menu 
    and select Edge Blending. The More option opens the second page of the Edge 
    Blending submenu. 
    Main Functions 
    Use Edge Blending controls to set the precise width, shape and midpoint you need to 
    blend overlapping edges together smoothly.   Ed
    ge Blending f  
    						
    							 Section 3: Operation 
    013-100199-04  3-65. 
    • Blend Width determines how much area is used for blending along an overlapping 
    edge. Slide bar values represent the number of eight-pixel steps used for the 
    blend. For example, a setting of “eight” creates a blended edge 24 pixels wide. A 
    setting of “0” signifies no blending. For best results in most applications, use a 
    blend width of 16-48 steps (128-384 pixels). 
    Ranges: 0-80 horizontal, 0-60 vertical. 
    • 
    Blend Shape determines the rate of 
    roll-off across the blend width, i.e. 
    how quickly the white levels across 
    the blend change from light and dark. 
    Increasing the Blend Shape setting 
    accelerates the rate of change at both 
    extremes so that less of the region 
    appears mid-gray (see Figure 3.19). 
    Decreasing the Blend Shape setting 
    slows the rate of change so that more 
    of the region appears mid-gray. For 
    most applications, this subtle control is 
    best left close to 50.  
    • 
    Blend Midpoint determines the white 
    level at the blend midpoint (the point 
    equidistant between the beginning and 
    end of the blend). Increasing the Blend 
    Midpoint setting creates a blend that 
    appears brighter than the rest of the 
    image. Decreasing the Blend Midpoint 
    setting creates a blend that is darker than 
    the rest of the image. A setting of 50 
    means the midpoint is approximately 
    50% black—for best results in most 
    applications, keep fairly close to this 
    default.

    • Show Blending Overlap turns your 
    defined blend width area to solid gray so 
    that, if needed, simply overlapping the 
    gray bars can seamlessly align two 
    adjacent images. Toggle the Show 
    Blending Overlap off to reactivate the 
    blend effect.  
    • NOTE: Blending Overlap appears as 
    Reserved when ChristieTWIST is 
    installed. 
    Other Functions  
    For convenience, the Edge Blending 
    submenu also includes related options for 
    enabling a specific color and/or test pattern, 
    or for working with colors or the lamp. Such 
    functions duplicate those provided elsewhere 
    in the menu system. 
     
    Edge Blending Procedure 
    NOTES: Before attempting to work with edge blending software functions, you must 
    1) physically align the projectors/images by correctly overlapping the displays from 
    your intended external source, and 2) Match colors and Brightness Uniformity. 
     IMPORTANT   
    For a shared edge, all Blend procedures and settings 
    should be identical on BOTH projectors. 
    1. Start with two projectors. Display full white field test pattern from both. 
    2. In the Edge Blending submenu, enable Edge Blending by entering a checkmark in 
    the top checkbox. 
    3. 
    SET STARTING POINTS FOR ADJUSTMENT: 
    • Set all blend widths to 0. 
    • Go to “More” and set everything in the Edge Blending (2) menu to 50. 
     
    Figure 3.21. Set Starting Points for Each Projector 
     
      
    						
    							 Section 3: Operation 
    013-100199-04  3-67. 
    4. SET BLEND WIDTH: On one projector, increase the Blend Width for an overlapping 
    edge (for example, if the projector’s image is on left, its right edge overlaps the 
    adjacent image—adjust Right Blend Width). Use the same setting on the second 
    projector for this shared edge. 
    5. Re-adjust width (both projectors) until the overly bright band at the midpoint of the 
    overlapping blends disappears or just changes to very light gray. For the shared 
    edge, use the same Blend Width setting on each projector. If the “best blend” 
    appears to be between two settings, choose the wider setting for both projectors. 
    6. 
    CHECK BLEND: If the blended region appears too dark or light in relation to the rest 
    of the image: 
    • Increase Blend Midpoint in both projectors to “lighten” the overall blend, 
    decrease to “darken” the overall blend. 
    • Adjust Blend Shape in both projectors to fine-tune change the amount of mid-
    gray intensity (as opposed to black/white) in the blend. 
    7. Repeat with remaining projectors / overlaps. 
    8. Check completed display wall with the desired external signal. 
    9. Adjust mechanical alignment if necessary to maintain perfect pixel-on-pixel 
    alignment over time. 
    In applications where you are projecting only white or light images, the Blend Width 
    may be slightly higher—set according to how much overlap you have between 
    images. Use the following as a guide (examples show overlapping width only—values 
    for overlapping height will differ): 
    • Recommended overlap is 12.5% - 25% 
     
    Similar to Edge Blending, Black Level Blending allows you to adjust the black level 
    hues of multiple adjacent projected images to create one large seamless display. Edge 
    blending must be enabled in order to use the Black Level Blending features. 
    Black Level Blending Procedure 
    NOTES: 1) Adjust white levels before adjusting black levels. 2) The zones in BLB 
    menu correspond to the Edge Blend zones. If a given Edge Blend zone width is set to 0 
    (i.e. no blend on that side) then the corresponding BLB zone is disabled. It only 
    becomes accessible when that Edge Blend zone is active. 
    1.   Start with two projectors. Select the black test pattern for both projectors from the 
    Geometry and Color submenu. 
    2.   In the Black Level Blending submenu, enable black blending by putting a 
    checkmark in the checkbox for each projector.

    3-68 013-100199-04   
     
    3.   Working with one projector at a time, use the center brightness slide bar to adjust 
    the center brightness (brightness of the non-blended region) so that the center 
    intensity matches that of the brightest blended region (the center of all images 
    when blending a 2 x 2 display is the target area). 
    4.   Use the following three color slide bars, Black Red Level, Black Green Level and 
    Black Blue Level, so the black hue of each projector matches. 
    5.   You can choose which of the next four options, Top, Bottom, Left, Right, to use 
    depending on which edge of the projector you are working with has been edge 
    blended. The blend width can be adjusted to line up properly but by default it 
    corresponds to the edge blending setting determined for that edge.  
     
     
     
    6.   The brightness and black hues of the blended region can be adjusted in more 
    detail in case fine-tuning is needed (may be only necessary for blending a 2 x 2 
    projector display because of blending differs for the sides and center). 
    NOTES: 1) The menu options vary depending on the Edge Blending parameters. 
    2) You may need to re-adjust the black level hues following the overlap 
    adjustments on each blended edge. 3) When adjusting six or more projectors, you 
    need to ensure that the hue and brightness of each target area is matched at 
    closely as possible. 
     
    As an alternative to using a keypad, most projector functions can be controlled 
    remotely, typically at a controller such as a PC, via 1) simple bi-directional ASCII 
    messaging on an Ethernet or serial communication link or 2) a web interface or 
    “ChristieNET” on an Ethernet network.  Using a PC interface can also prove to be 
    useful in instances where extreme warping is applied and the menu items become 
    illegible and hard to navigate. 
    VIA ASCII MESSAGING — Connect a serial link between your controller and the RS232 
    or RS422 port (recommended), or open an Ethernet socket (i.e., Telnet) between your 
    controller and the valid projector address. Valid ASCII codes and messages are 
    documented in the Christie Serial Communications document available at the Christie 
    website. 
    VIA WEB INTERFACE — Connect your PC to the projector’s Ethernet port. In your web 
    browser (Internet Explorer, for example), enter the IP address of the projector you 
    wish to control. This will start a password-protected ChristieNET application—enter 
    the factory default “
    ccm7” login and password to open the program. If the projector is 
    powered up, you can access assorted menu options and slide bars.

    of the Projector  
    						
    							 Section 3: Operation 
    013-100199-04  3-69. 
    Repeat for remaining networked projectors as desired. Keep in mind that multiple 
    units can be controlled from one PC, but each unit will be in its own ChristieNET 
    interface (web browser) at the PC. Likewise, you can make up to five separate web 
    locations to a single projector. 
    The default login provides access to security settings, where you can define other 
    users with the same or fewer rights. Use “unlimited” rights for most applications. For 
    all logins, the Service menu is still protected with its own password. 
    NOTES: 1) Any proxy server settings that interfere with this type of link should be 
    disabled for using ChristieNET. Disable through Internet Explorer’s < Tools> 
      . 2) Your PC must be Java-
    enabled to v1.4.2 or higher to run ChristieNET. 3) Depending on your projector 
    model, certain controls provided through ChristieNET are non-functional. 
     
    Occasionally the projector will encounter an error condition that can interrupt normal 
    operation. Such a condition can be caused by a simple invalid keypad entry, an input 
    signal error (most common) or a system error. The manner in which users are to be 
    notified of error conditions is set in the Menu Preferences menu: 
    • To see error messages displayed on-screen, select the “
    Screen” or “All” option. 
    • To be notified via a serial communication only, select the “
    RS232” option. 
    • To receive both types of notifications, select “
    All”.  
    • To disable error messages (except for “invalid user key entry”, which can’t be 
    hidden), select “
    Off”. 
    Note that a two-digit error code appears in the status LED display window located 
    beside the built-in keypad at the rear of the projector. Normal operation is indicated by 
    the “0n”status code. 
     
     
    Invalid User Entry 
    A keypad entry not recognized by the projector triggers a short on-screen error 
    message identifying the problem. For example, if you specify a channel number that is 
    not available, the message “Invalid Channel will appear. Or if you try to enter the 
    wrong password, you’ll see “Invalid Password”. Press 
     or Exit to clear the 
    message and try again. 
    NOTE: On-screen display of “Invalid User Entry” messages cannot be disabled, even 
    if Display Error Messages has been set to “Off”. 
    An input signal error message occurs if you are in presentation level (i.e., there are no 
    menus present) and have selected an input on which the projector detects a problem. 
    While menus remain operational and any key press will temporarily remove any 
    displayed error message, you must resolve the signal problem in order to permanently 
    eliminate the message.

    3-70 013-100199-04   
    No Signal 
    The message No signal occurs when there is no source signal detected at the 
    selected input—both HSYNC and VSYNC are inactive and the screen background is 
    black. Connect or correct the signal, or try another input. 
    Bad Sync 
    The message Bad Sync occurs when HSYNC or VSYNC are active but the signal 
    cannot be displayed. Such a condition occurs when only one of the two sync signals is 
    present or when either sync signal is unstable or is the wrong frequency. Correct the 
    signal or select another input. 
    Other Signal Error Messages 
    In addition to the common Bad Sync and “No Signal” errors, you may encounter a 
    signal error message indicating that HSYNC and/or VSYNC are either too fast or too 
    slow. When such a message appears, check the frequencies shown in the Status menu. 
    If they are correct, the projector does not recognize the signal. On some PCs you may 
    be able to change the settings to generate a compatible signal. If the frequencies 
    shown in the Status menu are incorrect, check the cabling to see where the problem 
    might originate. 
    When the projector encounters a system malfunction, either a System Warning 
    message or a System Error message may appear. Both types of messages are 
    accompanied by a numerical error code on the status LED display. A system 
    malfunction can be cleared with 
    Exit Exit from presentation level, but may indicate 
    the need for service by a qualified service technician. 
    NOTE: System messages appear on-screen only if Display Error Messages has been 
    set to “Screen” or “All”. 
    System Warnings 
    A system warning indicates that a system malfunction has been detected (see Status 
    LED Codes, below). A system warning message replaces any input signal message 
    and disappears when the input signal status changes. While the projector will remain 
    operational, the message indicates the presence of a potentially serious problem that 
    should be investigated. You can press 
    Exit Exit to remove the message, but for best 
    results you should reset the projector—power the projector down and up again with 
    the 
     (power) key. 
    System Errors 
    A system error message indicates that a serious malfunction has been detected and 
    must be investigated as soon as possible (see Status LED Codes, below). The projector 
    will no longer operate and must be reset—power the projector down and up again 
    with the 
     (power) key.   S

    The Status LED Codes 
    If the status code display on the back of the projector shows one of the following 
    values, you have encountered a likely system error requiring the attention of a 
    qualified service technician (see System Warnings and System Errors, above). 
    Acknowledge and clear the error with 
    Exit Exit from presentation level, or try 
    resetting the projector by powering it off and on again, cooling when necessary. 
    Consult Table 3.5 and contact your dealer if the problem persists. 
    The specific code number identifies the source of the error detected, and is 
    particularly useful in cases where the projector is far away. For example, the code 
    “27” means the lamp could not be turned on. Error codes for this projector are listed in 
    Table 3.5 below.
