such as DICOM, used for medical imaging, are also
available.
At the end of each monitor calibration proce-
dure, the display is automatically profiled and
highly accurate ICC/ColorSync color profiles are
generated and automatically registered with the
Color Management System. These profiles use the
Bradford Chromaticity Adaptation matrix.
Target and actual measured results are analyzed
and displayed, showing a wealth of information
about the display such as the measured color
gamut, greyscale color tracking, Delta-E, and lu-
minance values. Additional information about the
display monitor such as the model name, serial
number and the total number of hours that it has
been in use are also displayed.
Once SpectraView
II
has calibrated the display, the
OSD (On Screen Display) controls can be locked to
prevent accidental or unauthorized adjustment
which may invalidate the calibrated state of the
monitor.
The software features a Colorimeter function
which allows direct measurements to be taken
by the color sensor and the results displayed in a
variety of different formats.
The SpectraView
II
software integrates with the
NEC NaViSet Administrator network software
(Available separately from your NEC representa-
tive. Windows platform only) to provide remote
network access and monitoring of display
monitors. NaViSet Administrator is able to read,
display, and log the current calibration settings
and status of displays on a LAN. This feature is
particularly useful for large installations where
central monitoring and asset management is
needed.
Workflow Challenges With
Wide Color Gamut Displays
The use of a wide color gamut display is not with-
out its challenges. Many people who have used
a wide gamut display have come to realize that
while it is now possible to display colors that were
otherwise unable to be previewed on-screen,
challenges in other areas emerge.
For example, with being able to see colors on the
screen that were never before possible to display,
it is now easy to see problem areas in other parts
of the color workflow such as deficiencies in
printer or separation profiles.
The issue of having to continue to use some
legacy standard color gamut displays and
un-tagged source images in a color workflow is
another challenge.
Also it now becomes essential to utilize a color
management system with the display, by the cor-
rect use of ICC/ColorSync display profiles. Without
the use of a color management system, all colors
are mapped to the larger color gamut of the
display. This results in images that appear to be
super-saturated and distorted in color.
Accurate color profiles of the display allow the
color management system to correctly map the
source image gamut into the color gamut of the
display.
While the LCD2180WG-LED ships with color profiles
for the factory preset color settings, the use of
a color calibration package is normally essential
for accurate custom calibration and profiling of
the display.
The output color spectrum of the LCD2180WG-
LED display presents a unique challenge to
the current generation of colorimeter devices
which were never designed to be used on such
a display, just as LCD displays were a challenge
to colorimeters that were only designed for
CRT displays.
To overcome this, the optional SpectraView
II
color calibration package for the LCD2180WG-
LED display includes a custom calibrated
Gretag iOne Display V2 colorimeter that has
been specifically calibrated for accurate
measurement of the display. The device can
continue to be used to measure standard LCD
displays as well, if a multi-monitor configura-
tion is used.
NEC is actively working with manufacturers of
colorimeter devices to ensure that their fu-
ture standard products are able to accurately
measure the color characteristics of wide
color gamut displays.
