Optical Dimmer, enabled
This is the default setting. which allows automated brightness control and the lumens lock mode. At reboot the
home position of the dimmer is searched.
Since in this operation mode brightness is automatically controlled, the electronic control
of brightness and contrast of the IR Remote-Control unit is not available! (No manual
interference in the automated operation mode).
Optical Dimmer, disabled
The correct setting is Enabled!
Disabled should only be selected in case the dimmer is defective (stuck)! This mode
should only be used by advanced support engineers!
If
disabled
is selected, the dimmer will stay at its current position, and even at reboot no search for the home
position of the dimmer is performed.
In this mode the addr essing of r efer ence slits on the dimmer wheel will not be available to the lamp
optimization algorithm. In consequence it will be less powerful.
A non-uniformity in brightness might appear.
To provide a workaround, brightness and contrast can be adjusted by means of the respective buttons on the IR
Remote-Control unit.
Brightness adjusts the offset applied to the RGB input data.
Contrast changes the gain applied to the RGB input data.
The
Brightness
and
Contrast
dialog boxes show up after pr essing the
Brightness
/
Contrast
button on the IR
Remote-Control unit.

Only the settings for the active lamp can be modified. The active lamp is indicated in the
caption of the settings dialog.
The values are stored for both lamps individually.
