Display Walls consisting of OVERVIEW CDG67-DL projection modules are adjusted to homogene-
ous brightness. Therefore all projectors are individually adjusted to feature this common bright-
ness.
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
