COLOR ADJUSTMENTS BY X, Y 
 Use this submenu 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 3-61 - CIE 1931 
Chromaticity Diagram (without Yellow Notch Filter). 
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.

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’).
Use this submenu if you do not have specific 
color coordinates in mind and will 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.
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, will 
fluctuate as you use the projector, and will be different when you return to this menu in the future. 
These floating changes do not affect the x/y coordinates or gamut. 
Default Color Adjustments
Select the default values for the color adjustment without the Yellow Notch Filter. Refer to System 
Configuration – Geometry and Color, Color Adjustments by X,Y (below) for description.
• DEFAULT COLOR ADJUSTMENT WITH YNF:
Select the default values for the color adjustment with the Yellow Notch Filter. Refer to System

SYSTEM CONFIGURATION - DIAGNOSTICS AND CALIBRATION
•TEST PATTERN:
 Choose the desired internal test pattern to 
display, or select OFF to turn off a test pattern. 
Alternatively, use the   key for cycling 
through test patterns.
•GREY LEVEL: 
Set the 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. Use this diagnostic tool 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 to normal.
•COLOR ENABLE: 
Select which color(s) you want to see. Use this while working with color temperature, input levels or 
other special setup parameters. Colors can be enabled/disabled by entering the corresponding function 
code listed on the back of the standard remote keypad.
•RESERVED: 
No Function
•INPUT PEAK DETECTOR: 
A fast method for defining individual input levels, and improving 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.
•INPUT LEVEL DETECTOR: 
The “Input 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. To use:
1. Enable “Input Level Detector” and display a continuous grayscale.
2. Set “Input Level Value” to near black (such as 200).

3. Adjust Offsets to minimize area of black stripe.
4. Set “Input Level Value” to near white (such as 800).
5. Adjust Gains to minimize area of white stripe.
•INPUT LEVEL VALUE: 
Input Level Value defines the value to be used by the Input Level Detector in recognizing blacks and 
whites. See Input Level Detector, above.
•ASPECT RATIO OVERLAY: 
Check this box to display an overlay pattern over the image. The overlay shows the boxes correspond-
ing to the size and shape of different aspect ratios.
3.6 WORKING WITH PIP OR INPUT SWITCHING
PIP and Input Switching are independent but related projector features that both utilize two image-
processing paths within the projector. In the case of PIP, this double processing enables you to display 
two different images simultaneously – typically a smaller “secondary” image within a large “primary” 
background. In an input switch, the double processing 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 instantaneous, or slowed so that the current image appears to dissolve or “fade” into the new 
image.
Options for enabling and controlling PIP and Input Switching reside in the same menu. Since both 
features utilize the projector’s double processing capability, PIP and Input 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 Input Switching results, use two different signal types as defined below. Do not mix 
two signals of the same type.
NOTE: HD interlaced sources are not recommended for the PIP window.
Tips to keep in mind:
• When using two digital signals or one analog and one digital, the pixel clock frequency of each 
must be no more than 165 megapixels. 
• When using two analog signals, the pixel clock frequency of each must be no more than 90 mega-
pixels.
• Input switching may affect image quality in some cases.

• FRAME LOCKING:
How the projector controls the output frame timing based on the 
input signal. When set to Framelock, output image frames are 
locked to the input if possible. When Locked, the output is 
always locked to the primary input, never the PIP image. Free 
Run sets the output to close to 60Hz for all sources, This control 
must be set to Locked if a 3D-Stereo signal is used.
• AUTO INPUT SEARCHING: 
When enabled, the system will continually search for the next valid signal when no signal is present or 
when loss of sync occurs on the current user selected input. In the case of multiple signals to choose 
from, the order is based on slot, followed by inputs on that slot.
3.7 LAMP
• LAMP OPERATION:
Select the operational mode of 
the lamps. Auto-select mode 
will use the single lamp with 
the highest intensity. Lamp 1 
and Lamp 2 Single Lamp 
modes will only use the lamp 
specified. Dual Lamp mode 
will use both lamps together.
If a lamp fails to strike on the first attempt, up to 3 more attempts to strike are made. In Dual Lamp 
operation, after 3 failed attempts to stay in Dual Lamp mode, it will switch to Single Lamp operation. 
In Auto-select Single Lamp operation, a failure will cause a switch to the other lamp. In Single Lamp 
operation, if the selected lamp will not strike, then the projector will not turn on.
• LAMP MODE:
Determines how the lamp power and intensity are controlled. If 
“Maximum Brightness” the lamp burns as brightly as possible. 
Select “Constant Intensity” mode to maintain a specific brightness 
level over time. As the lamp ages, the projector will increase power 
as needed to closely maintain the required output from the lamp. 
Select ‘Constant Power’ to specify the power level supplied to the 
lamp. Both ‘Constant Intensity’ and ‘Constant Power’ modes extend lamp life.
• LAMP POWER:
Set the lamp power in Watts. The Power control represents the amount of power sent to the lamps. 
Power increases when operating in Intensity mode, until it reaches its maximum. The value remains 
stable when in Max Brightness or Power mode. If using Power mode, setting a lower power level 
reduces brightness and extends lamp life.

Section 3: Operation
• LAMP INTENSITY:
Adjust the lamp intensity to % of full. This value is used as a target value by the LiteLOC™ system to 
maintain constant intensity.
• YNF:
Refer to Image Settings Menu
.
• LAMP S/N (LAMP 1 and LAMP 2):
Enter the serial number for the specified lamp. This will apply the serial number to the current lamp 
statistics file. It will not perform the archiving as done by the CHANGE LAMP function.
• CHANGE LAMP:
Informs the projector that a lamp has been changed. This allows the serial number of the new lamp to 
be entered.
Lamp serial numbers are used for keeping statistics on each lamp used in each lamp position. Entering 
of serial numbers is optional, but is recommended. 
When using this function, the statistics for the previous lamp will be archived, and new statistics will 
be started for the new lamp. If this function is not used statistics will be cumulative, for both the new 
and old lamps combined.
• LAMP REGENERATION START TIME:
To extend lamp life, a lamp cannot operate continuously for more than 24 hours. Every 24 hours each 
lamp has to switch off for a regeneration period, by default a 15 minute period. This option allows you 
to set the time of day (hh:mm:ss) that the lamps can switch off. If operating with a specific single lamp, 
the lamp will switch off and there will be no image for the duration of the regeneration. If operating in 
Auto-select single lamp mode, the other lamp will be switched on for the duration of the regeneration, 
so that 24/7 operation may be maintained.
3.8 STATUS
The read-only Status menu lists a variety of details about the standard and optional components 
currently detected in the projector. Refer to the Sta tus  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 Sta tus menu identifies 
the current channel, its location, its frequencies and other details.

3.9 USING MULTIPLE PROJECTORS
IMPORTANT: When working with more than two projectors, work left to right, top to bottom.
When an installation requires multiple projectors, 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 
 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 Figure 2-21 - 
Mixed Network for full routing details.
.
MATCHING COLORS IN MULTIPLE SCREENS
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.
Preliminary Calibration
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. 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. 
To achieve consistency use a color meter to measure the native primary colors—red, green, blue, and 
white—as they appear at the screen. 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 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 access the Service menu (password-protected) return to the factory-set color primaries. Select the 
“Reset to Factory Defaults?” option in the Color Primaries submenu. Then repeat the calibration 
process describe above 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.
