Limitation of the Number of the Target Projectors when Using Multiple Projectors
When an ID is set for the projector and the remote control, you can use 
the remote control to operate only the projector with a matching ID. This 
is very useful when managing multiple projectors.
You can set an ID for the projector within a range of "1" to "9". The 
default value is Off.
You can set an ID for the remote control within a range of "0" to "9". The 
default value is "0". When the ID switch on the side of the remote control 
is set to Off, you can operate all projectors by the remote control 
regardless of the ID setting for the projector or the remote control.
The following table shows the possible combinations of projector ID and 
remote control ID.
When Remote Control Type is set to Simple from Operation in the 
configuration menu, you cannot set the remote control ID.Operation

Correcting Color for Multiple Projectors (Multi-Screen Color Adjustment)
When multiple projectors are lined up and projecting images, you can 
manually correct the brightness and color tone of each projector's image 
so that the colors projected from each projector match closely.
Set each projector to the same Color Mode before using the multi-screen 
color adjustment function.
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
Set "Multi-screen" to "On". 
C
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.
D
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 are adjusted to the brightest 
image 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.55
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).
