These coordinate adjustments move the 3 color points closer together to establish a “shared” gamut attainable 
by all projectors in the group. Adjust only as necessary to make sure that the resulting color palette is as large 
as possible. Adjust lamp power as necessary. 
7. All screens are now color-matched. Apply the new “User” gamut to a source by selecting it in the “Select 
Color Adjustment” list accessed in the Advanced Image Settings menu.
4.14.3 Using the Color Saturation Menu for Color Matching
FIGURE 4-22 COLOR MATCHING USING
COLOR SATURATION MENU
You may prefer to use the Color Saturation menu to match colors across multiple screens. In the three Color 
Adjustment submenus (Red, Green, Blue—see right), set all main values to 1000 and the secondary values to 0. 
Then judge by eye and adjust the slidebars as needed. Note that adjustments here define new x/y coordinates in 
the Color Adjustments by X,Y menu.
4.14.4 Achieving Brightness Uniformity
What is Brightness Uniformity?
 When used to refine screens already matched for their primary colors (see Matching Colors in Multiple 
Screens, above) and overall light output, proper adjustment of Brightness Uniformity can create an exception-
ally smooth screen in which:
• no area of the screen appears more red, green or blue than another 
• no area of the screen appears brighter than another
• color and light output from one screen closely matches adjacent screens
Although the Brightness Uniformity control can be used for a stand-alone projector, it is particularly useful for 
setting up and maintaining tiled images that form a cohesive display wall in which the color “cast” and light 
output appear uniform throughout each image as well as throughout the entire wall. The procedure provided 
here assumes a multiple-screen application.

Section 4: Advanced Configuration and Controls
 Before You Begin
Read through the entire procedure before attempting to adjust Brightness Uniformity controls, and keep in 
mind the following list of prerequisites and guidelines: 
•
ADJUST COLORS FIRST—Adjust the primary colors as described in Section 4.14 Matching Colors In Multiple 
Screens before working with Brightness Uniformity. This makes sure that primary colors, color temperature, 
and maximized light output are all matched from one screen to another. These matches are needed before you 
can achieve good Brightness Uniformity results.
•
RUN LAMP FOR 100 HOURS—Light output and Brightness Uniformity can vary significantly during the first 
100 hours of lamp use. For best results with new lamps, either set up Brightness Uniformity after this period, 
or do an initial setup and re-check at 100 hours.
•
SET LAMP POWER—Make sure each “Lamp Power” setting is at the maximum for your application while still 
maintaining a good overall match of light output from screen-to-screen. Achieving a uniform brightness will 
require a slightly reduced overall brightness—this reduction will make sure that there is enough range of 
adjustment when examining brightness variables from screen-to-screen.It will help prevent “maxing out” 
before matching to a specific color, zone or projector.
•
USE A “USER” COLOR TEMPERATURE—Adjust Brightness Uniformity for a User color temperature defined 
when you matched primary colors, and continue to use it for all sources displayed on the wall. Your other 
color temperatures will not necessarily be matched from screen-to-screen.
•
WHITE UNIFORMITY SLIDEBARS—White Uniformity slidebar values may not reduce to “0”. Each slidebar 
adjusts overall light output in a specific screen zone, but the value shown represents the current setting for 
green in this zone. When other “hidden” values (red or blue) are lower than green, during adjustment in the 
White Uniformity menu their values will reach “0” first, causing the slidebar to stop earlier than expected.
•
JUDGE BY EYE OR USE A METER—Good brightness uniformity can be achieved with either. 
Step 1: General Setup
a. Adjust primary colors (see Matching Colors in Multiple Screens) to make sure matched overall color 
temperatures and light output between screens. 
IMPORTANT: Verify that all WHITES and LIGHT OUTPUT are well-matched.
b. Enable the Brightness Uniformity checkbox. This will enable access to the uniformity controls and will 
apply the settings to your image.
NOTE: White Boost is automatically disabled (grayed out in menu) when you enable Brightness Uniformity.

RPMSP-D132U & RPMSP-D180U User Manual User Manual4-25020-100245-03  Rev. 1  (11-2010)
c. Select the 13 Point test pattern for display. This pattern provides 9 screen “zones” with 13 targets. 
FOR BEST RESULTS: Rather than examining the CENTER of each zone when assessing Brightness Uniformity 
adjustments, focus on extreme EDGES as indicated in the illustration at right.
d. In either Color Adjustment menu, select a “User” color. Then:
•If you have adjusted “User 1” Color Adjustment to create a well-matched wall (recommended), select 
“User 1” and then choose a color. Continue with Step 
1e.
•If you prefer maximum brightness rather than a particular color temperature, select “Max Drives”.
 
IMPORTANT 
Do not change User 1 Color Adjustments
in color-matched applications!
e. In the White Uniformity menu, set “Overall” to 50.0 and set all others to 0. This decreases the light 
output from each color just enough throughout the screen so that any color level can then be increased 
later as necessary for matching light output from zone-to-zone. Do not exceed 50.0 for “Overall”—a 
higher level will likely interfere with achieving brightness uniformity and is not recommended.

f. Make sure that overall light output remains well-matched from one screen center to the next. Where 
necessary, increase or decrease Lamp Power to recover center matches.
Step 2: Adjust Color (level of red/green/blue) in 8 Zones
NOTES: 
1) Ignore the brightness of individual zones. 
2) Ignore menu colors.
a. On each screen, compare the color temperatures in the 8 target zones (4 edges and 4 corners) to that of 
the color temperature of the center. Compare using a white field only, and take note of any areas that 
do not match the center. Also decide if any screen exhibits a more obvious color shift than other 
screens—begin with this screen in Step 
2b. 
b. Return to the Brightness Uniformity menu. Beginning with the screen that exhibits the most obvious 
color shift(s), for each edge that exhibits a noticeably different color temperature from the center, 
select the corresponding Uniformity adjustment menu—Left, Right, To p or Bottom. For example, if any 
part of the left side is too blue, too red or too green, go to the Left Uniformity menu and adjust the 
colors (i.e., change their light output) until all portions of the left side closely match the center color 
temperature. Adjust an edge first (focusing on its center), then adjust its corners. See Figure 4-23 
Match Zones to Center Color Temperature.
FIGURE 4-23 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 will match. Repeat Steps 
2a & 2b for all remaining screens.
Step 3: Adjust Light Output in 8 Zones
c. 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 4-24 Match Zones to Center Light Output. 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 4-24 MATCH ZONES TO CENTER LIGHT OUTPUT
Step 4: Readjust Color Temperature (level of red/green/blue) in 8 Zones
Return to Steps 
2a & 2b and, if necessary, fine-tune the zones so that they all still exhibit a single color 
temperature.
Canceling 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 blend white levels along the edges of 
multiple adjacent projected images to create a single seamless larger image.
4.15 Edge Blending (SXGA Only)
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).
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:

Section 4: Advanced Configuration and Controls
FIGURE 4-25 EDGE BLENDING CONCEPT
For best results, use the same projector model and type throughout your display wall. 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 2-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.
Use edge blending controls to set the precise width, shape and midpoint you need to blend overlapping edges 
together smoothly.
•
Blend Width determines how much area is used for blending along an overlapping edge. Slidebar values 
represent the number of 8-pixel steps used for the blend. For example, a setting of “3” 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 3.58) Decreasing the 
Blend Shape setting slows the rate of change so that more of the region appears mid-gray. For most appli-
cations, this subtle control is best left close to 50. 
FIGURE 4-26 “SHAPE” EXAMPLES
•Blend Midpoint determines the white level at the blend midpoint (the point equidistant between the begin-
ning 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.

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.
4.15.1 Edge Blending Procedure
Before working with edge blending software functions, you must: 
• Physically align the projectors/images by correctly overlapping the displays from your intended external 
source
• Match colors and Brightness Uniformity.
IMPORTANT: For a shared edge, all Blend procedures and settings must be identical on 
BOTH projectors.
1. Start with 2 projectors. Display full white field test pattern from both.
2. In the Edge Blending submenu, enter a checkmark in the top checkbox to enable Edge Blending
3. Set Starting points for adjustment.
a. Set all blend widths to 0.
b. Go to “More” and set everything in the Edge Blending (2) menu to 50.
FIGURE 4-28 SET STARTING POINTS FOR EACH PROJECTOR
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.

Section 4: Advanced Configuration and Controls
5. Re-adjust width (both projectors) until the overly bright band at the midpoint of the overlapping blends 
disappears or 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:
a. Increase Blend Midpoint in both projectors to “lighten” the overall blend, decrease to “darken” the 
overall blend.
b. 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 steps 1 to 6 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.
10. 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):
• If side overlap is 15%, set Blend Width to 24
• If side overlap is 20%, set Blend Width to 32
• If side overlap is 25%, set Blend Width to 40
• If side overlap is 30%, set Blend Width to 48
4.16 Remote Control of the Projector
As an alternative to using a keypad, most projector functions can be controlled remotely, typically at a 
controller such as a PC, via simple bi-directional ASCII messaging on an Ethernet or serial communication 
link.
Setting up a Remote Controller

To control projector functions remotely via Ethernet and your own controller, either open an Ethernet socket 
between your controller and the valid projector address, or connect a serial link between your controller and the 
RS-422 ports or the RS-232 In port. Connect all ports, if desired.
For complete information, including a list of valid ASCII messages and how to structure them for use, obtain 
the current Christie Serial Communications document.
4.17 Error Conditions
Occasionally the projector will encounter an error condition that can interrupt normal operation. This can be 
caused by a simple invalid keypad entry, an input signal error (most common) or a system error. How users are 
notified of error conditions is set in the Menu Preferences menu:
• To see error messages displayed on-screen, select the “
Screen” option
• To be notified via a serial communication only, select the “
RS-232” option.
• To receive both types of notifications, select “
All”.  
						

							Section 4: Advanced Configuration and Controls
RPMSP-D132U & RPMSP-D180U User Manual User Manual4-31020-100245-03  Rev. 1  (11-2010)
• To disable error messages (except for “invalid user key entry”, which can’t be hidden), select “Off”.
The 2-digit error code that corresponds to the message appears in the status display window on the electronics 
module. During normal operation the status code “0n” is displayed.
4.17.1 User Errors
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. Press   or   to clear the message.
NOTE: On-screen display of “Invalid User Entry” messages cannot be disabled, even if Display Error 
Messages is set to “Off”.
4.17.2 Input Signal Errors
These messages occurs if you are in presentation level (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 the error message, you must resolve the signal problem to permanently eliminate 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
Occurs when HSYNC or VSYNC are active but the signal cannot be displayed. This condition occurs when 
only one of the two sync signals is present, or when either sync signal is unstable or the wrong frequency. 
Correct the signal or select another input.
Other Signal Error Messages
You may encounter a signal error message indicating that HSYNC and/or VSYNC are either too fast or too 
slow. When this message appears, check the frequencies shown in the Status menu. If they are correct, then the 
signal is not recognized by the projector. 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.

4.17.3 System Warnings / Errors
When the projector encounters a system malfunction, a System Warning or a System Error message will appear. 
These messages are accompanied by a numerical error code shown in the status display window. A system 
malfunction can be cleared with      from presentation level, but may indicate the need for service by a 
qualified service technician. For best results reset the projector—power the projector down and up with the 
 (power) key. Wait at least 90 seconds and allow for proper cooling.
NOTE: System messages appear on-screen only if Display Error Messages is set to “Screen” or “All”.
System Warnings
Indicates that a system malfunction exists. 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 a potentially serious problem that should be reported to the manufacturer. Reset the projector.
System Errors
Indicates that a serious malfunction exists and must be reported to the manufacturer as soon as possible. The 
projector will no longer operate. Reset the projector.
The Status Display
If one of the error codes in table is shown in the status display window you have a system error that will require 
the attention of a qualified service technician.
 Acknowledge and clear the error with   
 from presentation level, or try resetting the projector by 
powering it off and on again, cooling when necessary. Consult and contact your dealer if the problem persists 
or if you encounter a code not listed in this table.
For detailed information, monitor the RS-232 IN port. For an indication of engine communication failure, send 
(SST? 1 15) to get a report.
