NEC Spectraview 3090 Users Manual

Calibration  and  Profile  Steps -  selects  the  number  of  measurement  steps  to  take  when  calibrating  and 
profiling the display. A larger number of steps will generally result in a more accurate grayscale calibration, but 
will increase the calibration time. 32 steps is the recommended setting for most applications. 
Recalibration  Reminder  Period  -  sets  the  interval  after  the  display  is  calibrated  until  a  calibration  reminder 
message  is  displayed.  The  default  value  is  2...

Generate ICC Profile after calibration - selecting this will automatically generate an ICC/ColorSync monitor 
profile after the display is calibrated. This option should be checked for most applications.
Set  as  Windows  Color  Management  System  Monitor  Profile  (ÿ  Windows  version  only)  -  selecting  this 
will automatically associate the generated ICC monitor profile with the Windows Color Management System.

Options are:
•	Automatic - the optimal setting based on the color sensor model and the display monitor type is 
automatically used. It is recommended to use this setting. 
•	Calibration Sensor - uses the values measured by the calibration sensor. For normal color gamut 
displays this is the recommended option since the calibration sensor can accurately measure these 
primary colors. For wide color gamut displays some colorimeter based calibration sensors may not be...

Lock OSD (On Screen Display) controls when calibrated - selects if the monitor’s On Screen Display control 
buttons are locked when the monitor is calibrated. Locking the controls can be useful to prevent accidental or 
unauthorized adjustment of the monitor once it is calibrated. Options are:
•	Don’t lock 
•	Lock all except Bright and Contrast
•	Lock all
Note: The controls will be unlocked if the calibration is turned off in the main window.

Primary Colors
Red,  Green  and  Blue  CIE  x,y  - shows  the  measured  color  coordinates  of  the  display’s  primary  colors. 
These values represent the color gamut of the display. The Source of the color measurements indicates if 
the Red, Green and Blue values came from either the Calibration Sensor or Factory Measurements, and will 
depend on the Primary Colors Chromaticity Source setting in the Preferences dialog.

The  Color  Gamut  tab  graphically  illustrates  the  color  gamut  of  the  display  for  comparison  purposes  as  a  2D 
representation of the 3D color gamut volume. The display’s color gamut can be compared to the color gamut 
of several popular color spaces.
The  source  of  the  color  measurements  for  the  display’s  color  gamut  will  depend  on  the Primary  Colors 
Chromaticity Source setting in the...

Target  -  illustrates  the  target  tonal  response  curve  of  the  currently  selected  Target.  This  display  will  be 
calibrated  to  match  this  curve.  This  curve  will  be  disabled  and  not  shown  if  the  Target  Gamma  is  set  to

Inf\frmati\fn \bind\f\b - C\fl\fr Tracking tab
The Color Tracking tab shows graphically how well the grayscale (colors from black to white) of the display is 
conforming to the currently selected Target. Ideally all points along a grayscale measured on the display should 
have the same white point (chromaticity) and should follow the luminance curve of the  Target.
Deviations from this ideal can result in grayscale color tracking errors which can be seen as shifts...

The DICOM Conformance tab shows graphically and numerically how well the calibrated display conforms to 
the ideal DICOM (Digital Imaging and Communications in Medicine) response when a DICOM Target curve of 
is used. 
The  aim  of  the  DICOM  response  is  to  have  a  perceptually  linear  luminance  response.  Each  step  along  the 
display’s grayscale should have an equally perceptive increase in luminance. The...
