4. Advanced operation
The available display functions for your Nio 5MP LED Display are:
•
Native:
If you select Native, the native panel behavior will not be corrected.
•
Dynamic Gamma 1.8
or
2.2
: These are gamma functions that are shifted to take into account the
non-zero luminance of an LCD panel when driven with a “black” signal. They are especially useful in
CT applications to improve the perception of low Houns
fi
eld values.
•
DICOM:
DICOM (Digital Imaging and Communications in Medicine) is an international standard that
was developed to improve the quality and communication of digital images in radiology. In short, the
DICOM display function results in more visible grayscales in the images. Barco recommends selecting
the DICOM display function for most medical viewing applications.

4.11 Ambient Light Compensation (ALC)
About ALC
Ambient Light Compensation (ALC) can only be enabled on your display when the DI-
COM display function is selected. Therefore, please refer to "Display functions", page
20 to correctly set the display function.
When ALC is enabled, the DICOM display function will be recalculated taking a preset ambient light cor-
rection value into account. This value is determined by the selected reading room. Therefore, it is also
important to select a realistic reading room when enabling ALC. This can be done by following the instruc-
tions in "Reading rooms", page 22.
To enable/disable ALC:
1. Bring up the OSD main menu.
2. Navigate to the
Con
fi
guration > Calibration > Ambient Light
menu.
3. Enter the
Ambient Light Compensation
submenu.
