Designed for professionals with color-critical applications, SpectraViewII combines award-winning NEC display technology with a color-measurement sensor and sophisticated calibration software. The result is highly accurate, reliable, repeatable, feature-rich solution for display calibration and profiling.
The SpectraViewII 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. With SpectraViewII, the video graphics adapter is not used at all to make any gamma or Tone Response Curve corrections to the display, so the fidelity of the system is maintained.

SpectraViewII is available on Apple Mac OS, Microsoft Windows, and several Linux distributions.
Each LCD display monitor supported by SpectraViewII features three internal 14, 12 or 10 bit LUTs (depending on model). These tables allow very precise adjustments to be made to the display's Tone Response Curve without reducing the number of displayable colors.
By making adjustments directly in the display hardware, optimal settings are configured without any user interaction. SpectraViewII 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.
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.
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.
SpectraViewII 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.
SpectraViewII 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.
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.
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.
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.
For use in medical imaging environments
SpectraViewII can be used to calibrate the monitor to the DICOM GSDF gamma curve. The built in conformance test can be used to verify accuracy of calibration and conformance to the recommended standard for
viewing grayscale images.

The new M1 based Macs such as the MacBook and Mac mini are not yet fully compatible with SpectraView as of macOS 11.3. Due to changes in macOS, the SpectraView software is unable to fully detect connected NEC displays. Apple is aware of this issue and it is expected to be resolved in a future macOS update. An special version of SpectraView is available specifically for M1 based Macs so that the display can be detected in most cases. A USB cable must be connected to the display from the M1 based Mac. Older display models that do not support USB can not be supported. Please check for system updates when available. SpectraView is compatible with other non-M1 Macs running macOS 11.
Installing SpectraView requires an account with administrator privileges.
This version of SpectraView is supported on 32 and 64 bit versions of Microsoft Server 2003, Windows Vista, Windows 7, Windows 8, Windows 8.1, and Windows 10.
Installing SpectraView requires an account with administrator privileges.
Requires a PC with 64 bit Ubuntu Linux operating system v10.04 or higher. Other variants such as RedHat, CentOS, Linux Mint, and SUSE Linux should also work but may need certain system libraries to be installed, and the configuration steps may be different from those described in the software installation documentation. 32 bit versions of Linux are not supported.
Communicating to the display via either DDC/CI or USB is supported. USB is the preferred connection if supported by the display model.

Have a problem with your Product? Here you'll find common questions. If you don't find what you need, please contact our support team.
For Delta-E values of less than 2 there is almost certainly no need to recalibrate. For values higher than 3 it is important to understand what the cause is and whether it's significant.
The calibration and adjustment process has inherent variability due to many factors such as the repeatability of color sensor measurements, and changes within the display as it is adjusted. The basic accuracy and repeatability specifications for most sensors are +/- 0.002 or higher for CIE xy, and +/- 2% for luminance. These variances alone can give rise to Delta-E values of up to 2 or 3.
When a specific Intensity value is being used for the calibration, the Delta-E value is comprised of the luminance and color differences. Differences in color are much more critical than a difference in relative luminance. Look at the results of the calibration shown in the Information window to determine if the high Delta-E value is caused mainly by a shift in color or in luminance.
High Delta-E values can also occur if a specific Intensity value is being used for the calibration and the display is not capable of achieving the specified Intensity value. The calibration will always aim to achieve the specified White Point, even if the Intensity value could not be reached. If the display can not be calibrated to achieve the specified Intensity value modify the value accordingly.
In some situations, the display Intensity will drift slightly for several minutes after it is adjusted. Since the measured value used to calculate the final Delta-E result is taken up to one or two minutes after the display was adjusted, a higher Delta-E value may be shown, even though the calibration process achieved the specified Target values during the calibration process. Selecting the Extended luminance stabilization time option in the Preferences can be used to try and minimize this effect.
SpectraView will automatically install the device drivers for the iOne Display color sensor. However it is assumed that if you are using a third-party sensor, then the software that came with it will have already installed the drivers for the device. If you did not install the third-party software then the device drivers will need to be manually installed.
Drivers for all sensors are available on the SpectraViewII CD-ROM or in the \Program Files\Sharp NEC Display Solutions\SpectraViewII\Drivers folder after installing SpectraView (on 64 bit versions of Windows the folder location is \Program Files (x86)\Sharp NEC Display Solutions\SpectraViewII\Drivers).
