When projecting to a wide screen from multiple projectors, you can adjust
the difference of brightness and color tone between each projected image to
create a seamless screen.
There are two general methods of projecting from multiple projectors.
U Projecting different images from each projector, and creating a seamless screen
V Projecting the same image from each projector, using the Scale function to
project a large image
The basic setting method is the same, but you have to use the scale
function to adjust the projection position for
V.

"Scaling an Image (Scale)" p.69
Here we will take
U as an example.

• We recommend setting the focus, zoom, and lens shift at least
30 minutes after you start the projection, because images are not
stable right after turning on the projector.
• If the values for Geometric Correction are large, the image position
adjustment for overlapping images becomes difficult.
• The Test Pattern can be displayed to adjust the projection status
without connecting video equipment.
s "Displaying a Test Pattern" p.29
• If you project a dot by dot image that can be projected without
being enlarged or reduced, you can make adjustments precisely.
Preparation

projection function.
