Section 3: Operation 013-100199-04 3-63. 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. Figure 3.17. Match Zones to Center Light Output Step 4: Readjust Color Temperature (level of red/green/blue) in Eight Zones 4a) Return to Steps 2a & 2b and, if necessary, fine-tune the zones so that they all still exhibit a single color temperature.
Section 3: Operation 3-64 013-100199-04 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. Figure 3.19. “Shape” Examples Figure 3.20. “Midpoint” Examples
Section 3: Operation 3-66 013-100199-04 • 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. Black Level Blendin g f
Section 3: Operation 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. 3.11 Remote Control 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. 3.12 Error Conditions User Errors f In put Signal Errors f
Section 3: Operation 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 ystem Warnings / Errors f
Section 3: Operation 013-100199-04 3-71. 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. Table 3.5 Error Codes Code Description GENERAL 12 Software bug.
