Overview

Designed for professionals with color critical applications, SpectraView II combines the award winning NEC display
monitor technology with a color measurement sensor and sophisticated software. The result is highly accurate, reliable,
repeatable, and feature rich display calibration and profiling solution.
The SpectraView system uses a color sensor 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, 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.

Main Features and benefits

SpectraView provides the following features and benefits:
• Automatic calibration - SpectraView communicates with the display monitors using Display Data Channel -
Command Interface (DDC/CI) which is a two-way communications link between the video graphics adapter and
display monitor using the normal video signal cable. No extra cables are necessary. All adjustments to the monitor
settings are done automatically using this communications link. A USB connection between the host PC and
display can also be used if supported (supported models only, refer to the "USB control" column in the "Features by
Model" tables on page 58 and page 60 for the specific capabilities of each display model). It is not necessary
to manually configure the monitor as all of the necessary settings are made by the software.
• High bit depth internal Look Up Tables (LUTs) - Each LCD display monitor supported by SpectraView II
features three internal 10, 12, or 14 bit LUTs (depending on the model). These tables allow very precise adjustments
to be made to the display's Tone Response Curve without reducing the number of displayable colors or introducing
color banding artifacts.
• Multiple Calibration Sets - Different display 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.
• Informative - At the end of each display 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 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.
• Flexible - SpectraView 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 value or to the maximum possible that the display can achieve.
• Monitor locking - Once calibrated the OSD (On Screen Display) controls for the display monitors can be
locked to prevent accidental or unauthorized adjustment which may invalidate the calibrated state of the monitor.
