Introduction
Brightness uniformity
In a multi channel system the brightness can vary over the different channels/projectors. The brightness level can be matched using
:
1.
CLO: in this case the light power is matched over the different projectors, see CLO in the Lamps section
2.
Black level : this will act on the brightness of the "black" color of the image part situated outside the soft edge zones.
