5. Advanced operation
Diagnostic This mode provides the full calibrated luminance
and is intended for using the display for diagnostic
purposes.
Text In this mode, the luminance is reduced to
approximately half of the luminance. This
is intended for using the display with of
fi ce
applications such as word processing.
Please note that text mode is not persistent, once
powered off, the unit will restart in diagnostic mode.
As the NIO 3MP LED Display is intended to be used in a diagnostic environment, the
diagnostic mode should always be selected.
To select a viewing mode:
1. Bring up the OSD main menu.

About display functions
Native, uncorrected panels will display all grayscale/color levels with equal luminance increments. Stud-
ies have shown however, that in medical images certain grayscale/color parts contain more diagnostic
information then others. To respond to these conclusions, display functions have been de
fi ned. These
functions emphasize on these parts containing crucial diagnostic information by correcting the native panel
behavior.
Native If you select Native, the native panel behavior will
not be corrected.
Dynamic Gamma 1.8
Dynamic Gamma 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.
User This display function will be automatically selected
when display functions are de
fi ned by MediCal
QAWeb.
Gamma 1.8
Gamma 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.
To select a display function:
1. Bring up the OSD main menu.
