The solution is to adjust the ‘Centre’ value to compensate for this centre brightness
error. By increasing this value, it will increase the brightness of the non-overlap
area.
To get this value right, you must first make sure that the units connected to the
projectors are outputting black – e.g. in the Adjust windows menu you can disable
the output. Then increase the ‘Centre’’ value until the non-overlap area’s
brightness has increased to be the same as the overlap (centre) area.
Where horizontal and vertical edge blending is being performed – e.g. a 2x2
arrangement a ‘Side’ adjustment will also be shown. This value increases the
brightness of the overlapping areas, with the exception of the centre ‘square’ where
all projectors overlap.
