Display Walls consisting of OVERVIEW D projection modules are adjusted to homogeneous brightness. Therefore all
projectors are individually adjusted to feature this common brightness.
This individual projector adjustment is done after set up of the Display Wall by the Barco Support Technicians. On
the screen, the brightness is measured by means of a lux meter, and the sensor of the optical dimmer (DIS) is
calibrated based on this measurement.
The user can adjust the brightness between 100% and 50% by means of the optical dimmer. This adjustment can
be performed via the command Brightness|Set Brightness.
To adjust the brightness, proceed as follows:
