display functions have been defined. These functions emphasize on these parts containing crucial diagnostic
information by correcting the native panel behavior.
The available display functions for your Nio 2MP 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 Hounsfield 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.
• User: This display function will be automatically selected when display functions are defined by MediCal
QAWeb.
• Gamma 1.8 or 2.2 : Select one of these display functions in case the display is to replace a CRT display
with a gamma of 1.8 or 2.2 respectively.
The settings of the display must be adapted to suit the requirements of the visualization software. In
case of doubt, please contact the vendor of the visualization software.

1. Bring up the OSD main menu.
2. Navigate to the
Configuration > Calibration menu.
