ReadMe Information for macOS

Version – Legacy 32-bit build 181024 – October 24, 2018



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 either via the video graphics adapter over the video cable – known as DDC/CI (Display Data Channel - Command Interface) – or via a separate USB connection to the display (supported models only). Using a USB connection to the display is highly recommended for compatibility and speed.

Support for the X-Rite i1Display, i1Pro, i1Pro2, i1Monitor, i1Studio, and ColorMunki, and the Datacolor Spyder3, Spyder4, and Spyder5 color sensors is included and automatically installed with SpectraView. Drivers for the BasICColor Discus must be installed using a separate installer application included on the installation media or .DMG.


Release Notes

IMPORTANT - 32-bit Build

Due to issues found with the 64 bit build of SpectraView during testing, only this 32-bit build is being released at this time. Users of the previous 64 bit version 1.1.38 are encouraged to use this 32 bit version instead. A 64 bit version of SpectraView will be available at a later date. Users may see a compatibility warning message when first launching this application and this message can safely be ignored.

New Display Firmware

New firmware for the following display models is available which adds some functionality improvements.

Navigate to the following page for more information:

Optional Launch Agent

SpectraView can optionally query the display monitor each time a user logs in to see if any settings have changed since the last calibration. This is normally only necessary if multiple users are logging into the same Mac. To enable this functionality copy the file "com.necdisplay.SpectraViewII.launch.plist" located in the "Extras" folder in the SpectraView DMG image to the "/Library/LaunchAgents/" folder on the system. Administrative rights will be required to copy this file. The SpectraView II application must be located in the Applications folder on the system.


Known issues

PPC based Mac support discontinued

As of version 1.1.12, SpectraView no longer supports PowerPC based Macs. This is due to the lack of PPC support in 3rd party color sensor support libraries. Users with a PPC based Mac must use an older version of SpectraView.

Mac OS X 10.6 and earlier support discontinued

Support for Mac OS X versions 10.6 and earlier has been discontinued as of version 1.1.30.

Mac OS X 10.7 and 10.8 support

In Mac OS X versions 10.8.0 to 10.8.2, and Mac OS X 10.7.5, support for monitor communications via DDC/CI is not functioning on some Macs, including systems with DVI video outputs, and when using a miniDisplayPort to DVI cable or adapter. Users with an NEC MultiSync PA or P series display (excluding P221W) can connect a USB cable between the host PC and one of the USB inputs (upstream ports) on the display to provide the necessary monitor communications via USB. This issue has been resolved in Mac OS X 10.8.3 and all customers impacted by this issue are encouraged to update to OS 10.8.3 or higher.

X-Rite ColorMunki:

The "ColorMunki Create" version of ColorMunki is not supported by SpectraView. The "ColorMunki Design" and "Colormunki Photo" versions are supported.

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 manually restart the colormunki service or restart your system.

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

You must turn off the ColorMunki Service in System Preferences > "X-Rite Devices" to allow SpectraView to access the device.
To use the ColorMunki software again you must turn the ColorMunki Service back on.

Note: It is not recommended to connect this device using either USB extension cables or USB hubs as it may cause errors detecting or taking measurements from the device. Whenever possible connect it directly to the Mac.

Supported Operating Systems and Macs

This issue is due to a hardware incompatibility with the Intel GMA X3100 graphics processor and cannot be fixed by a future software update. Note that these monitors will otherwise function normally on these models of Apple Macs.
