When you restart NioWatch, the last selected display function
is automatically selected.
The following display functions are available:
Name Description
DICOM Select a DICOM display function for most
medical viewing applications.
The DICOM function results in more visible
grayscales in the images.
Dynamic Gamma 2.47 This gamma function best matches the
behavior of a grayscale CRT display.
The ‘dynamic’ gamma function is shifted
to take into account the non-zero lumi-
nance of an LCD panel when driven with a
“black” signal.
Dynamic Gamma 2.2 This gamma function best matches the
behavior of a color CRT display.
The ‘dynamic’ gamma function is shifted
to take into account the non-zero lumi-
nance of an LCD panel when driven with a
“black” signal.
Gamma 2.2 Select this display function in case the dis-
play is to replace a CRT display with a
gamma of 2.2
Gamma 1.8 Select this display function in case the dis-
play is to replace a CRT display with a
gamma of 1.8
Linear If you select Linear, the native panel
behavior will not be corrected.

• To select another color temperature, select an item from the
Color Temperature drop-down box. This function is available
for E-2320 C displays only.
After selecting another color temperature it may be
necessary to recalibrate the display. Therefore, check the
Calibration tab to see if calibration is necessary: In case the
display is still in calibrated position, the text in the calibration
tab will say ‘The selected display is calibrated ...’. In case the
display is no longer in calibrated position, the text will say
‘The selected display uses the factory settings ...’.
• To adjust display luminance manually, adjust the Luminance
slider. This function is not available for MFCD/MFGD 1218
and MFCD 1219 displays.
The luminance setting is saved when the system is shut
down.
If the slider is positioned above the CAL mark, the luminance
is in calibrated position, as determined during the latest
calibration. If the slider is not above the CAL mark, the
luminance is not in calibrated position.
Important notices about DICOM compliance:
• If you want the system to be DICOM compliant, you must
select the DICOM display function and calibrate the display.
After calibration, the luminance must remain in calibrated
position to maintain DICOM compliance.
• When you have used NioWatch to calibrate the display to the
DICOM display function, it is the NioWatch application that
ensures DICOM compliance. Be aware that if you use the
display without NioWatch afterwards, the display is no
longer DICOM compliant. In that case, please consult Barco
MIS service to reset the display function to DICOM.

Here you can calibrate display(s), revert to the latest calibration,
revert to default factory settings and view the result of the latest
calibration. The possible options are explained below.
Things to consider before starting calibration:
1. If you control color displays and wish all grayscale levels on
the display have the same chroma or color temperature,
make sure the option “Use Constant Chroma Calibration for
color displays” in the Application Settings dialog is set. See
“Calibration tab” in the description of the Application
Settings dialog.

2. If you have multiple Nio displays of the same type connected
(multi-head system), consider if you wish to equalize the
display you calibrate to a reference display.
The first calibrated display in the system is the reference
display.
Equalization means the luminance of the display you are
calibrating will be matched to the luminance of the reference
display.
If you wish to equalize the display, you must close the
Display Settings dialog and make sure the Equalization
option in the Application Settings dialog is set. See
“Calibration tab” in the description of the Application
Settings dialog.
To calibrate the display using the Barco LCD sensor:
1. If you have multiple displays connected (multi-head system),
select the display you wish to calibrate by clicking on the
corresponding numbered icon in the Display Settings dialog.
2. Click the Calibrate button.
3. A message appears, showing the different calibration
options.

5. Follow the guidelines on the screen to complete the
calibration successfully.
Note:
If the Equalization option is set in the Application Settings
and NioWatch finds at least one other display of the same
type that is calibrated, the “Match with reference” page
appears during the calibration process.
Figure 8: Match with reference
To equalize the display, check the option “Match this display
with display....” and click Next. The display number that
appears in this option, refers to the reference display, which
is the first calibrated display in the system.

Equalization
Here you can check the Equalization option, allowing you to
match all the displays from a multi-head system to the
luminance of the first calibrated display of the system.
Suppose you work with a system containing 2 Nio displays of the
same type, and you wish display (2) to have the same output
luminance as display (1). Therefore first calibrate display (1).
Next, calibrate display (2) while the Equalization option is
checked.
The first calibrated display in the system is the reference display.
