Color Wheel Calibration — SUBMENU 
The Color Wheel Calibration submenu allows you to set the timing of the two color 
wheels in the projector. It is important the color wheels are correctly calibrated for the 
colors and shades in the displayed image 
to appear the same. Incorrectly calibrated, 
the colors will appear in various 
unmatched shades throughout the image. 
Typically,  this adjustment is only 
required when a color wheel is replaced. 
1.  Select the single lamp operation mode that corresponds to the color wheel you 
want to calibrate. For example, select “Single Lamp 1” when calibrating color 
wheel 1 and “Single Lamp 2” when calibrating color wheel 2.   
2. Enter the Color Wheel Calibration submenu – the Color Ramp test pattern will 
automatically display and the “Color Enable” option will automatically switch to 
White
. 
3.  Adjust  “Color Wheel 1 (or 2) Delay” so the transitions across each color bar 
appears smooth. 
4.  Repeat Step 1 – Step 3 for the other color wheel. NOTE: Wait for 35 seconds 
when requesting a change in single lamp operation modes to allow for one lamp 
to warm up and the other to turn off. 
5. Verify adjustments by choosing different colors in “Color Enable”.  
NOTES: 1) Upon entering the Color Wheel Calibration submenu, the “Color Enable” 
option automatically switches to white and the color ramp test pattern displays.  
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 blacklevels 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. 
The single “Option Card” entry in the Configuration menu identifies which optional 
input module (a.k.a. cards) is present at 
INPUT 5 (Option 1). If the option slot 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 2 digital signals or 1 analog and 1digital, 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

to enable and define 
how you want to use 
PIP. 
 
 
Swap Main and PIP Image 
Toggle the current picture-in-picture relationship so that the primary (main) image 
becomes secondary (PIP), and the secondary image becomes primary. Swapping is 
available only when PIP is enabled. 
NOTE: There may be a slight delay when swapping the Primary and Secondary 
images.

only. This checkbox turns the 
secondary source on and off. 
NOTE: Disable PIP and Best Switching for Interlaced sources > 35kHz. 
 
PIP Size and Position – SUBMENU 
Most controls in the PIP Size and 
Position menu adjust the PIP 
(secondary) image in the same 
fashion as their counterparts in the 
main Size and Position menu 
adjust the main image—see 3.5, 
Adjusting the Image for details. 
Exceptions are: 
POSITION PRESETS –Set the 
location of the PIP (secondary) 
image in the display. 
ASPECT RATIO PRESETS – Choose the desired aspect ratio for your PIP pixels. Use 
the “Default” aspect ratio when incoming format has square pixels (most common). 
This ensures that the resulting PIP image maintains its intended aspect ratio. Use   Workin

“Anamorphic” for NTSC signals having narrower pixels--this will stretch the pixels 
horizontally to regain the intended aspect ratio of the PIP image. NOTE: If the image 
is already resized at the source it will remain that way in the PIP window. If, for 
example, an NTSC signal is already set to anamorphic through the Resize and Preset 
menu it will remain that way in the PIP window. If the NTSC signal is formatted as 
widescreen at the source, then the image in the PIP window will appear with black 
bars above and below it. 
PIP Image Settings — 
SUBMENU 
Adjust the PIP (secondary image) without affecting the size or position. The primary 
image remains unchanged. See 3.5, Adjusting the Image for details 
PIP Border Width 
Set the desired line thickness for your PIP window border.  
PIP Border Color 
Select the desired color for the PIP window border. 
NOTES: 1) Numbers 7 and 8 on the Picture-in-Picture and Switching submenu 
control switching parameters. 2) Disable PIP in order to work with Seamless 
Switching. 3) Disable PIP and Best Switching for Interlaced sources > 35kHz. 
 
Seamless Switching is the ability to instantly and/or smoothly switch sources, and is 
controlled with options 7 and 8 in the PIP and Switching menu. To use Seamless 
Switching, PIP must be disabled. 
Tips for best source switching:
 
• Make sure a channel has been configured for each source. 
• Progressive digital and analog sources are recommended. 
• Set Image Optimization to Best Switching (see below). 
• For best results, use the same frame rate and gamma setting for each. 
  
NOTE: Avoid using two Interlaced sources. 
 
Image Optimization 
Choose whether to use Best Switching or whether you prefer to optimize image 
quality, whichever best suits your needs. When Best Switching is selected, sources are 
switched almost instantaneously without a dark state in between images. Eight-bit 
processing is used to maximize the opportunity for a seamless transition.  Best 
Switching is recommended only when seamless switching is necessary. Best Quality 
maximizes allocated resources to maintain image quality by using 10-bit processing 
and a single source only. If selected, there may be a brief dark state between images.  
NOTE: Disable PIP and Best Switching for Interlaced sources > 35kHz. 
 
Fade Time 
Set how long (in seconds) it takes to gradually dissolve one image into another for a 
source switch when Image Optimization is set to Best Switching. NOTE: PIP must be 
disabled for Fade Time to take effect. Also, the PIP window must be closed to activate 
it.    Working with Seamless

The dual lamp illumination system used in this projector gives you the flexibility to 
choose an operation mode (single lamp or dual lamp) to suit the specific needs of your 
installation. The unique lamp auto-switching feature also provides the potential to 
operate the projector for extended periods without interruptions related to lamps or 
lamp replacement.  
A complete understanding of how the projector works is critical in effectively 
maintaining its continuous operation. The Lamp Menu and the options provided, such 
as selecting a lamp operation or power mode and monitoring lamp status can help in 
achieving bright, uninterrupted projection.  
The projector by default is set to power on in Dual Lamp mode. No light appears on 
the wall during the first 25 seconds of power up, as this is the time it takes to ignite 
the lamps. As the lamps warm up to their full potential, you will notice brightness 
gradually increasing. Before sending a keypad command, wait for the projector to 
complete its initialization phase (“ON” will appear in the status LED display), 
otherwise the request will be ignored. After this time, you can switch to one of the 
Single Lamp modes or make any other software request.  
On rare occasions, a lamp may not ignite on the first attempt. A brief description of 
what you will notice in each of the lamp modes is described below. 
• In Dual Lamp mode, only the light from the lamp that successfully ignited 
will be seen on the wall. In this case, the projector will wait 90 seconds and try 
re-striking the lamp. The projector will attempt only 2 re-strikes of the lamp. If 
it fails to turn the second lamp on it will automatically switch to the Single 
lamp operation mode for the lamp that was successfully turned on. If during 
one of its retries, the projector successfully turns the second lamp on, the lamp 
operation mode remains in Dual Lamp.  
If both lamps fail at the same time, an error is reported and the projector 
automatically powers down.

• In Single Lamp mode, the projector will try to strike the lamp again in 90 
seconds (considered re-strike #1).  Only after the third attempt (re-strike #2) 
will the projector declare the lamp as “Failed to Strike” (in Lamp submenu) 
and automatically switch to the single lamp operation mode for the lamp that 
was not ignited. All lamp specific menu options will then change to reflect the 
true lamp operation mode of the projector. 
NOTE: P-VIP lamps, by nature, do not successfully ignite when “hot” and 
therefore the 90 second wait period is taken by the projector before each strike 
attempt and between powering the projector down and up again.  
Lamp operation modes will also automatically change if there is a failure of one of the 
lamp related components, such as the lamp driver, color wheel or fan. An error code 
will be displayed in the status LED or through the RS-232 serial communications log 
that indicates which component has failed. The lamp status will also show one of 
several messages that points to the failed component. The lamp in this instance is 
typically still okay and does not require replacement.  
MANUALLY SWITCHING FROM DUAL TO SINGLE LAMP MODE – Switching from dual 
to single lamp operation mode occurs immediately. The result is an instant dimming 
of the displayed image. At this time, you can modify the lamp power or adjust other 
settings to increase desired brightness.  
MANUALLY SWITCHING FROM SINGLE TO DUAL LAMP MODE – When you manually 
switch from a single lamp mode to the dual lamp mode, the projector immediately 
tries to ignite the second lamp. If the first attempt to ignite the lamp fails it will wait 
90 seconds and try again.   
MANUALLY SWITCHING BETWEEN SINGLE LAMP MODES – When manually switching 
between single lamp modes, there is a 35 second overlap when both lamps are on. 
This overlap allows the “new” lamp to warm up before the other lamp is turned off. 
The new lamp operation mode displays immediately in the menus. Only after the third 
attempt (re-strike #2), will an error message display to indicate the type of error that 
was detected. If no specific error is detected, then the error will be “Failed to Strike”. 
If this occurs, the first lamp will not turn off and the projector will continue to operate 
in the original lamp operation mode. In summary, it could potentially take the 
projector up to 4.5 minutes to successfully switch lamp modes. The projector will 
attempt to maintain light on the wall during this time. NOTE: If a problem is fixed 
before the last strike attempt the lamp could turn on. 
If a lamp fails during operation, the projector will immediately attempt igniting the 
other lamp if it’s not already on. Only in this case, will there be a brief interruption in 
the display. 
NOTE: A lamp will naturally decrease in brightness as it ages. Lamp life can also be 
decreased further by a frequent change in lamp operation modes (number of times its 
ignited).

Figure 3.24. The Lamp Menu 
LAMP MESSAGE  - Enter a checkmark to enable a warning message that will appear 
upon power-up when the lamp has reached the specified lamp limit and should be 
replaced. Delete the checkmark to prevent display of this message—instead, when 
your lamp expires only the status LED display will provide the visual warning to 
replace the lamp. 
NOTES: 1) It is recommended that the Lamp Message checkbox remain enabled. 2) If 
a lamp warning message appears during power-up, press 
Ex i t to temporarily cancel 
the message. The message will continue to appear upon power-up until you install a 
new lamp. 
LAMP LIMIT  - Set the lamp limit to the number of hours you expect to log on the 
current lamp before replacing it. The limit by default is 1500 hours. 
LAMP MODE - Select a lamp mode to control the light output of your projector — 
select “Max Brightness” to run the lamp as brightly as possible or “Power
”  (default) 
to continually run the lamp at the specific wattage set by adjusting the 
POWER 
slidebar.  
POWER – Adjust the slidebar when LAMP MODE is set to “Power”, to indicate the 
number of watts (250-300) applied to the lamp.
 In general, a lower power level 
generates a dimmer image. Specifying a maximum power level is the same as 
operating in “Max Brightness” mode. 
LAMP OPERATION – One of the key features of the projector is that it can be operated 
with one or two lamps on. From the pull down list, select the lamp operation mode 
you want to operate the projector in. “Dual Lamp” is the default. 
• 
DUAL LAMP – Select “Dual Lamp” to operate the projector with both lamps 
on. In this mode, you can achieve maximum brightness output by the 
projector. Refer to Lamp Operation and Switching on the previous page for 
more details on how the projector behaves when in this mode.   
• 
SINGLE, LAMP #1 OR SINGLE, LAMP #2 – Select “Single, Lamp 1” or “Single, 
Lamp 2” to specify the lamp you want to operate the projector with. The other 
lamp remains in “reserve” and will only turn on if the current lamp “fails” for 
some reason or if the mode is manually selected.    
						

							Section 3: Operation 
3-52   Christie DS+60/DW30/Matrix 3000 User’s Manual  
NOTES: 1) The projector will automatically shutdown if it detects both lamps 
have “failed” (this includes lamps not installed). 2) The lamp operation mode 
will not automatically switch to a previous mode once a “failed” lamp is 
replaced. It must manually be selected. 3) It takes approximately 25 seconds 
for a cold lamp to reach full brightness when it is first turned on. 4) Power is 
cut to a lamp only when the lamp operation mode is switched to the other 
lamp. IMPORTANT  - the original lamp stays on for 35 seconds to allow the 
new lamp to warm up before power is cut and lamp operation modes change.  
MORE LAMP 1 (MORE LAMP 2) - There are two separate lamp submenus that can be 
accessed from the Lamp menu. Each submenu is dedicated to one lamp – you can 
view specific lamp information, such as lamp hours, lamp history and the current 
status of the lamp. You can also change lamp operation modes.
 
LAMP HOURS  
 - This read-only information shows the current number of hours 
logged on the current lamp. Whenever a new lamp serial number is detected it begins 
to log time for the new lamp. This information also appears in the Status menu. 
LAMP S/N  - This read-only information displays the serial number for the current 
lamp. NOTE: When a lamp is installed, the projector automatically detects the serial 
number and displays it here. The serial number is not manually entered. 
LAMP 1 (OR 2) STATUS – This read-only information displays the current status of a 
lamp and can be viewed any time during operation. Refer to the list below for the 
possible lamp status messages and their meaning: 
• 
“Good” continually appears as the status until there is a failure with one of the 
lamps. Then one of the other error messages will display.  
• 
“Failed to Strike” will display when the projector fails to turn a lamp on. This 
may or may not be lamp related. Further investigation is required. 
• 
“Lamp Not Installed” will display when a lamp is not detected. If present, 
check to ensure the lamp is fully inserted and connected to the terminal block. 
• 
“Turned Off Unexpectedly” will display when a lamp or lamp related 
component, such as a lamp driver fails. Check for an error code on the status 
display. 
• 
“Interlock Tripped” will display when the lamp door is opened for a lamp that 
is still on. In this case, the lamp will automatically be turned off. 
• 
“Cooling Fan #8 (or #10) Failed” will display when one of the corresponding 
lamp fans fail. (Cooling fan #8 is associated with Lamp #1 and Cooling fan 
#10 with Lamp #2) 
• 
“Color Wheel Stopped” will display when a color wheels ceases operation. 
• 
“Operation Error” will display when the lamp driver reports an operation error 
and the lamp is off. This typically occurs when trying to turn on a hot lamp. 
• 
“Driver Vcc too Low” will display when a lamp driver fails. 
LAMP HISTORY - This read-only option lists the lamp serial 
number and corresponding lamp hours of the lamp most recently 
installed. Lamp History is automatically updated when a new 
lamp is installed.

The read-only Status menu lists a variety of details about the standard and optional 
components currently detected in the projector. Refer to the Status menu for versions 
of hardware and software installed, the type (size) of lamp, the hours logged in total 
and for a specific period (such as a rental period), and for your projector model name 
and serial number. In addition, the Status menu identifies the current channel, its 
location, its frequencies and other details. 
Scroll the full Status menu using

 When an installation requires multiple projectors, you can use the RS232 serial ports 
to daisy-chain the units together and control the group with a single keypad or a 
computer/controller connected to the first projector. In such a network, you can 
choose to broadcast commands to the entire group, or use the 
Proj key as desired to 
limit responses to an individual projector. 
Alternatively, you may want to add projectors to a hub on an Ethernet network. See 
2.6, Connecting Multiple Projectors for full routing details. 
NOTE: Refer back to 3.6, Adjusting System Parameters and Advanced Controls for 
complete information about communicating with multiple projectors. 
In a multiple-projector wall, you will likely want to precisely match color and intensity 
from image-to-image so that the full wall is as uniform as possible. This matching is 
typically done in conjunction with brightness uniformity and edge blending. 
Preliminary Calibration 
As a final part of the manufacturing process, all primary colors in the projector are 
precisely set to pre-established values to ensure that overall color performance is 
optimized and is as accurate as possible (refer back to Figure 3.21). Upon installation 
at a site, however, lighting and other environmental factors may slightly change how 
these colors appear on your screen. While the change is negligible in most cases, you 
may prefer to recover the originally intended color performance before trying to 
match colors from several projectors. Or you may be renting a projector in which the 
colors were corrected for use at its previous site, but are not ideal for yours. 
The recommended first step in achieving such consistency is to use a color meter to 
measure the native primary colors—red, green, blue, and white—as they appear at the 
screen and record these as Color Primary Settings in the Service menu (password-
protected) for each projector. On the basis of these new values, which are stored in 
memory, each projector will then automatically calculate any necessary corrections to 
reproduce the original factory colors under the current environmental conditions. This 
essentially calibrates a projector to its surroundings, compensating for factors such as 
screen type, lamp and/or ambient lighting that can alter the final color characteristics 
on-screen, and will improve color accuracy and consistency in a group of projectors. It 
ensures a good starting point for further customizing and matching; however, is not 
critical for all installations. 
To return to the factory-set color primaries, such as when a projector is moved to 
different site, you must access the Service menu (password-protected). Select the 
Reset to Factory Defaults? option in the Color Primaries submenu. Then repeat the 
calibration process describe above, if desired, and continue with matching of colors.

Color Adjustment Procedure 
Once the Color Primary Settings are calibrated for the site (see above), use the Color 
Adjustments by X,Y or Color Saturation menu to further refine each projector’s 
fundamental colors so that the hue and intensity of each color appears the same from 
one display to another. Once matched, you will have created a single new shared 
range of colors or “color gamut” that all of your projectors can produce. This 
palette—named User 1, 2, 3 or 4—can be applied or disabled for a source at any time 
throughout a bank of adjacent displays, simplifying both the setup and maintenance of 
a “seamless” wall. 
1.  Set up and optimize all projector settings. You can ignore color temperature, since 
you will be redefining color performance in this procedure, but do optimize each 
projector in every other aspect. Closely align all screen edges. 
2.  Assign projector numbers to make communications easier. Use desired keypad. 
3.  Use the same lamp mode for all projectors, and do the following:
