How to set up the system
In this ch apter, the setup procedure for the projectors is exp lained, but a setup procedure m ust also be performed for the picture
source.
In order to obtain a satisfying result for the Blend f unction, the overlap / Blend zone are recomm en ded to be
at least 10% of the picture width.
The basic principle is that the ove rlap setup in the source sh
all correspond with the blend w idth setup for the projector. That means
that if the over lap zone for the source is set to 500 pixels, the width of the blend zone for the projector also mus t 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 t he same time, establish a n overlap in the pictures between the two screens.
Then adjust the remaining irregularities by using the shift and warp features in the pr ojectors to obtain the las t fine tuning of the
alignment.
Setup the source to a blend which corresponds with the pr eset overlap on the screen. There are different way s to do this, d epending
on the source. Refe r to the source unit’s m anual for this issue.
Adjust the Blend for the projectors as descri
bed below.
