About SpectraView II

SpectraView II provides automatic display monitor color calibration and profiling functions for supported models of NEC display monitors.

The software uses a two way communications link with the display monitor via the video graphics adapter and normal video cable. No extra cables are necessary. Special support is required in the video graphics display driver in order to provide this functionality.

This communications link is called DDC/CI (Display Data Channel - Command Interface) and is an industry standard developed by VESA (Video Electronics Standards Association)

The MultiSync PA Series of display monitors also feature using an optional USB connection to the display for communicating, instead of using DDC/CI. This can be used in cases where the video graphics adapter is not supported.

USB drivers for the X-Rite Eye-One, iOne Pro2, Datacolor Spyder 3, 4 and 5, and BasICColor Discus color sensors are automatically installed if selected in the SpectraView software installation process. Drivers are not needed for the X-Rite iOne Display Pro and NEC SpectraSensor Pro color sensors. Drivers for other color sensors are copied to the SpectraView application directory but are not automatically installed.

The X-Rite ColorMunki Display device introduced in mid-2011 is not supported.

If the X-Rite ColorMunki software is installed, it will prevent SpectraView from accessing the device even if the main ColorMunki application is not currently running.

If you are using the ColorMunki software prior to version 1.1.0:

SpectraView will detect if the ColorMunki software is running and give the option of closing it automatically.
To use the ColorMunki software again after SpectraView has closed it, you must run the colormunki.exe application from the Startup menu in Windows.

If you are using the ColorMunki software version 1.1.0 or newer:

You must turn off the ColorMunki Service in the Windows Control Panel > "X-Rite Device Services" to allow SpectraView to access the device.
To use the ColorMunki software again you must turn the ColorMunki Service back on.
