Quick and easy measurements. The SpectraView
II
 system, 
available for Mac OS and Windows, uses an ultra-sensitive, 
custom-calibrated NEC/X-rite iOne Display 2 colorimeter 
to take color measurements of the display screen during 
calibration. The software analyzes these measurements 
and sends color adjustment commands directly to the 
display monitor. This means that color adjustments are 
made in the monitor rather than in the video graphics 
adapter, resulting in full use of the number of colors 
available on the graphics adapter and a much brighter 
image with the maximum possible color gamut. With 
SpectraView
II
, the video graphics adapter is not used at all 
to make any gamma or tone response curve corrections to 
the display, so the full color resolution and fidelity of the 
system is maintained.
10-bit Internal Look Up Tables (LUTs) - Each LCD monitor 
supported by SpectraView
II
 features three internal 10-
bit LUTs. These tables allow precise adjustments to be 
made to the display’s tone response curve with minimal 
reduction to the number of displayable colors. Since the 
tone response curve correction is stored within the display 
and not on the host system’s video graphics card LUT, the 
display can be calibrated on one machine and then used 
on another and still maintain calibration as long as a digital 
video signal is used.
Display Data Channel Command Interface (DDC/CI) - 
SpectraView
II
 communicates with the monitor using DDC/
CI, which is a two-way communications link between the 
video graphics adapter and display monitor using the 
standard video signal cable. No extra cables are necessary. 
All adjustments to the monitor settings are done 
automatically using this communications link.
Multiple calibration sets - Different monitor calibrations 
can be instantly loaded, allowing quick and easy switching 
between different calibration settings without the need 
to re-calibrate the display. Each time a calibration set is 
loaded, the necessary monitor settings and ICC/ColorSync 
profiles are automatically updated.
Calibrated display information - At the end of each 
monitor calibration, an information window is displayed, 
which shows the results of the calibration and includes 
a wealth of information about the display such as the 
measured color gamut, grayscale color tracking, Delta-E 
and luminance 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.
Calibration status validation - SpectraView
II
 will query 
each calibrated monitor to see if any controls have 
changed since the last calibration. If anything has changed, 
the previous calibrated state can be restored automatically.
Application flexibility - SpectraView
II
 provides many 
features and options that make it flexible enough to be 
used in a large variety of applications, including full DICOM 
support for medical imaging. The display luminance can be 
adjusted to either a specific user-defined value or set to 
the maximum the display can achieve. In addition, custom 
target response curves can be created in addition to 
presets such as L* and SMPTE.
Network support (Windows only) - SpectraView
II
 
integrates with the NEC NaViSet™ Administrator 
network software (available separately from your NEC 
representative) 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 an existing network 
(LAN). This feature is particularly useful for large 
installations where central monitoring and asset 
management is needed.
Monitor locking - Once calibrated, the On Screen Display 
(OSD®) controls for the display monitors can be locked to 
prevent accidental or unauthorized adjustment, which may 
invalidate the calibrated state of the monitor.
Monitor profiling - After calibration, 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.
Colorimeter function - 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.
