Correcting Color for Multiple Projectors (Multi-Screen Color Adjustment) 58
Correcting Color for Multiple Projectors (Multi-Scree n 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.

played.

darker or lighter by correcting 1 to 5 or 5 to 1.
DCorrect 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,
