Multi-Projection Function

You can setup multiple projectors to project one large and wide image.
You can adjust the difference of brightness and color tone between each
projected image to create a seamless screen.
a
• Set 4K Enhancement to Off.
• We recommend setting the focus, zoom, and lens shift at least
20 minutes after you start the projection, because images are not
stable right after turning on the projector.
• If the values for Geometry 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"
• If you project a dot by dot image that can be projected without
being enlarged or reduced, you can make adjustments precisely.

Adjustment Procedure

image from the projector set as the master projector (Screen Matching).
Before selecting the master projector, set Light Source Mode to Custom for
all projectors, and set Brightness Level to the maximum. Set the projector
with the darkest projected image as the master projector.
