Figure 3.29. Copy X/Y Values into All Projectors 
6. In each projector, judge by eye and adjust x/y coordinates slightly in the following 
manner: 
 To match reds, decrease “Red 
X” until full field red screens 
match. 
 To match greens, decrease 
“Green Y” until full field 
green screens match. 
 To match blues, increase both 
“Blue X” and “Blue Y” until 
full field blue screens match.

Using the Color Saturation Menu for Color Matching 
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 Figure 
3.30), set all main values to 
100 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...

SET LAMP POWER—Ensure each “Lamp Power” setting is as high as possible for 
your application while still maintaining a good overall match of light output from 
screen-to-screen. By nature, achieving a uniform brightness will require a slightly 
reduced overall brightness—this reduction will help ensure that you have enough 
range of adjustment when examining brightness variables more closely from...

In either Color Adjustments menu, select a “User” color. Then: 
 If you have created a “User 1” color gamut (recommended) for a well-
matched wall, continue to Step 1e. 
 If you prefer maximum brightness rather than a particular color temperature, 
select “Max Drives”. 
 IMPORTANT  
Do not change User 1 Color Adjustment 
in color-matched applications!

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

Christie Edge Blending is an innovative set of software functions that can quickly and 
easily blend the edges of multiple adjacent full screen 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...

Optional Blinders 
If desired, you may wish to install the optional mechanical blinders at the projector 
lens. These adjustable blades help to blend blacklevels along edges of the image, and 
are available in a separate kit.
 
Since the blinders and Edge Blending menu controls are intended to complement 
each other, with blinders primarily affecting blacklevels and software primarily 
affecting whitelevels,...

 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%...

25% each. Display full white field test pattern from both. 
2. In the Edge Blending submenu, enable the top checkbox to activate all controls.

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. 
 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
