Global effect 1- Parameter 2
The DMX values from the range of 0-255 are used to step segment by segment throw the image grid. The DMX
value of 0 corresponds to the upper left segment of the image grid. The stepping runs from the left to the right and
down from top (see example for field 8x3 segments bellow
).
Global effect 1- Parameter 3
This channel enables to transform displaying of the segment edges-sharp or blended edges. You can also display
the blue and red auxiliary frame with the alignment marks for easier alignment of the adjacent segments:

Note
. DMX values of both channels
Global effect 1
and
Global effect 1- Parameter 1
have to be set at the same
values on all fixtures used in the picture merging.
If the channel
Global effect 1 - Parameter 3
is set to the range of 171-180, the aspect ratio of an actual image is
displayed in the image. The feature is activated when the Picture Merging is active only. The value of the aspect
ration changes during setting of Keystone/zoom channels. The function is useful when the image is projected on
the skewed surface, at Picture Margin and at video projection (usually 16: 9 aspect ratio ).
Aspect ratio 4:3
Aspect ratio 16:9
