Correcting Color for Multiple Projectors (Multi-Screen Color Adjustment)
When multiple projectors are lined up and projecting images, you can 
correct the brightness and color tone of each projector's image with 
multi-screen color adjustment so that the colors of images from each 
projector match closely.
In some cases the brightness and color tone may not match completely 
even after correction.
Auto Iris does not work while this function is activated. Even if Auto Iris 
is set to On, and Multi-screen is set to On, Auto Iris does not work.
Summary of Correction Procedure
When multiple projectors are set up and you need to make corrections, 
use the following procedure to correct one projector at a time.
Correction Method
After setting up the projectors, correct the brightness and tone for each 
projector to reduce the differences.
ProcedureA
Press the [Menu] button and select Extended - 
"Multi-screen" from the configuration menu. 
B
Select Lv. to be corrected in Adjustment Level.
•Each time a level is selected, the pattern of the level selected is dis-
played.
•You can start correcting from any level, usually you can make it 
darker or lighter by correcting 1 to 5 or 5 to 1.
C
Correct the brightness with Brightness Correct.
•When you select Lv. 5, all the images are adjusted to the darkest 
image from multiple projectors.
•When you select Lv. 1, all the images adjusted to the brightest im-
age from multiple projectors.
•When you select Lv. 2 to 4, all the images are adjusted to the 
mid-range brightness image from multiple projectors.
•Because each time the [Enter] button is pressed the image dis-
played changes between the pattern display and the actual image, 
you can check the correction results and make corrections in the 
actual image.
1.Set the projector ID and the remote control ID.
To limit operation to one target projector, set a Projector ID for the 
target projector, and set the same ID for the remote control. sp.48
2.Correct the color difference.
You can carry out color correction when projecting from multiple 
projectors. You can adjust from black to white in five stages called levels 
1 to 5, and in each of these 5 levels you can adjust the following two 
points.
•Correcting brightness
You can correct the image brightness to make them all equal.
•Correcting color
You can adjust the image color to make them match more closely by 
using Color Correct. (G/R) and Color Correct. (B/Y).

age.
