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.
12-bit Internal Look Up Tables (LUTs) - Each LCD monitor 
supported by SpectraView
II
 features three internal 12-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.
