Overlap settings
Overlapping is of no use for OverView rear projection systems. With an OverView rear
projection system connected to the TransForm A the feature should not be enabled, even if
the X and Y values are set to 0!
Overlapping is only supported with the UGX Graphic Card!
The overlap settings can be used with projectors for front projection which support the overlapping feature (edge
blending). It is used to have smooth transitions between the projections of multiple projectors. An array of pixels
at the border between two adjacent projectors is generated twice for each of the two projectors. This enables to
overlap the projection area.
To use overlapping the
Overlap active
checkbox must be enabled. The number of double-generated pixels be-
tween projectors located next to each other is determined with
X
and between projectors located on top of each
other with
Y
.
The visible amount of pixels of the complete projection, the desktop size, is reduced accordingly.
Overlap can only be used with the orders
columns
or
rows
. If
custom
has been selected before it is automati-
cally changed to
columns
.
Overlap can only be switched, if no instance of video.exe is running. Therefore close all
video windows before activating overlap.
