8.5.4.4 Set Brightness
Before setting brightness, it is recommended that Lamp Optimization, (cf. Lamp
Optimization) has been performed at least once per lamp!
Use this menu to switch between a relative brightness setting and an absolute brightness setting.
Per factory default, in new systems the value is set to relative (no brightness
information about the used lamp is available).
In running system, the correct setting is absolute brightness (measured by means of the
DIS sensor, and the target value should be the same for all projection modules of the
configuration in order to ensure a homogeneous brightness distribution.
Changing the brightness setting, requires the following steps:
• Move to Service | Color/Brightnes | Set Brightness
• Press Enter to select.
The following dialog box is displayed to show/to select the brightness setting and to see/change the
corresponding values.

to allow maximum brightness (100%).
In this operation mode, the entries of the Brightness menu are grayed out, since these refer to absolute values!
