on the screen. An example can be: If the source is a pc, you may want to hide the menu bar at the bottom of the screen.
8.5.2 Set up the system
How to set up the system
In this chapter, the setup procedure for the projectors is explained, but a setup procedure must also be performed for the picture
source.
In order to obtain a satisfying result for the Blend function, the overlap / Blend zone are recommended to be
at least 10% of the picture width.
The basic principle is that the overlap setup in the source shall correspond with the blend width setup for the projector. That means
that if the overlap zone for the source is set to 500 pixels, the width of the blend zone for the projector also must be set to 500 pixels.
First step is to align the image from the projectors as accurate as possible in a mechanical way, meaning without any optical correc-
tions. At the same time, establish an overlap in the pictures between the two screens.
Then adjust the remaining irregularities by using the shift and warp features in the projectors to obtain the last fi ne tuning of the
alignment.
Setup the source to a blend which corresponds with the preset overlap on the screen. There are different ways to do this, depending
on the source. Refer to the source unit’s manual for this issue.
Adjust the Blend for the projectors as described below.
