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.
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. s p.29
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 us-
