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.

USB drivers for the X-Rite i1, i1Pro2, Datacolor Spyder3, Spyder4, Spyder5, and SpyderX, and BasICColor Discus color sensors are automatically installed if selected in the SpectraView software installation process. Drivers are not needed for the X-Rite i1Display Pro / X-Rite i1Display Pro Plus and NEC MDSVSENSOR3 / NEC SpectraSensor Pro color sensors. Drivers for other color sensors are copied to the SpectraView application directory but are not automatically installed.

Known issues

"Error: Unable to update the ICC profile" error message in Windows 10

An issue introduced in a Windows update prevents SpectraView from being able to replace an existing ICC profile because it is locked by the system. It cannot be manually deleted either.

The following workaround can be used if this issue is encountered:

1. Open the Windows Task Manager (press CTRL+ALT+DEL and select Task Manager).
2. From the Windows Task Manager select the "Services" tab.
3. Look in the name column for the service called "DisplayEnhancementService" and select it.
4. Right click and select "Stop". The status should change to "Stopped".
5. While SpectraView is still open and displaying the "Error: Unable to update the ICC profile" error message, click "Retry" and the ICC profile will be updated.
If the error message is immediately displayed again, confirm that:
• The Windows Color Management window is not open.
• The Windows Display Properties window is not open.
• Close any applications that may be using color management such as the Windows Photo Viewer.
6. Restart the "DisplayEnhancementService" by right-clicking on the name again in the Task Manager and selecting "Start."

AMD video settings:

• New versions of the AMD video settings application, for Radeon and FirePro products, include a feature called "Color Temperature". This feature can severely impact the accuracy of on-screen colors when it is not set to the default "6500K". Do not set this to "Automatic" or to any value other than "6500K".

HDMI and video graphics adapter driver settings:

• When using an HDMI video connection to the display, beware that many video graphics adapters will by default treat the display as a TV-type device rather than a computer monitor. The range of video levels used in the video signal is different between TV devices and computer display monitors. TV devices typically use the range 16 to 235, rather than the full 0 to 255 range used by computer display monitors.
  
  If incorrectly configured, this can lead to:
  
  
  • Very poor black levels (because “black” output from the computer is actually level 16 rather than 0).
  • Darker than normal whites (because “white” is level 235 rather than 255).
  • The resulting screen image will appear slightly washed out and lacking in contrast.
  • Significant color banding may be present.
  • When calibrating the monitor, on some display models the calibration may fail and display an error message.
  • On other models the calibration will finish, but the final results will show a distorted gamma curve.
  
  Therefore, if using an HDMI video connection, be sure to check the video graphics adapter driver settings to make sure the correct range for a computer display monitor are being used. The terminology for the setting varies between each manufacturer and driver package, but some common examples are given below:
  
  
  • Intel: “Input Range” or “Quantization range” should be “Full Range”.
  
  
  • Nvidia: “Output dynamic range” should be “Full”, “Normal”, “High”, or “RGB (0-255)”.
  
  
  • AMD / ATI: “Color Pixel Format” should be “RGB 4:4:4 Format PC Standard (Full RGB)”.
  
  
  Consult the help for the video graphics adapter driver being used for specific details.

USB support with MultiSync displays:

(C751Q, C861Q, C981Q, EA231WU, EA241F, EA241WU, EA242F, EA244UHD, EA245WMi, EA245WMi-2, EA271F, EA271Q, EA271U, EA272F, EA275UHD, EA275WMi, EA295WMi, EA305WMi, EA304WMi, EX241UN, EX341R, MA431, MA491, MA551, P212, P232W, P241W, P242W, P243W, P435, P404, P484, P495, P554, P555, P754Q, PA231W, PA241W, PA242W, PA243W, PA271Q, PA271W, PA272W, PA301W, PA302W, PA311D, PA322UHD, PA322UHD-2, UN462A, UN462VA, UN492S, UN492VS, UN552, UN552A, UN552S, UN552V, UN552VS, UX552, UX552S, V404, V404-T, V484, V484-T, V554, V554-T, V554Q, V654Q, V754Q, V864Q, V984Q, X551UHD, X651UHD, X651UHD-2, X841UHD, X841UHD-2, X981UHD, and X981UHD-2 only)

• This version of SpectraView II supports communicating with these displays via USB. Connect a USB cable (not supplied) between the host PC and one of the USB inputs (upstream ports) on the display. Make sure the correct USB input is selected on the OSD. Using the USB connection instead of DDC/CI can be manually selected from the Display Configuration dialog in SpectraView.

Note: The video cable connection is still required in addition to the USB connection.

X-Rite i1Display Pro / X-Rite i1Display Pro Plus:

• This version includes support for the X-Rite i1Display Pro / X-Rite i1Display Pro Plus color sensor.
• The X-Rite ColorMunki Display device introduced in mid-2011 is not supported.
• The NEC MDSVSENSOR3 / NEC SpectraSensor Pro is based on the X-Rite i1Display Pro / X-Rite i1Display Pro Plus sensor and is supported. Note that this sensor may not be supported by non-NEC software.

X-Rite i1Pro or i1Monitor:

If using the X-Rite i1Pro or i1Monitor

• Be sure to allow the device at least 15 minutes to warm up before calibrating the display.
• Measurements may drift slightly causing inaccurate measurements, especially when measuring colors close to black.
• Selecting the Average low light measurements option in the SpectraView Preferences is highly recommended when using this device.
• Be sure to carefully follow the instructions for zero calibrating the device.

X-Rite i1Display:

• In some rare cases this color sensor may "hang" when measuring black color patches during calibration. If the calibration appears to be stuck measuring black for more than 30 seconds, try moving the sensor so it is measuring something other than black (for example turn the sensor around so it is measuring the ambient light). This should cause the calibration to resume, at which point it should be canceled an restarted.

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 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.

• 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 host PC.

Photo Research PR-655, PR-670, PR-680, PR-730, and PR-740 Spectroradiometers:

• The USB drivers for Windows from Photo Research must be installed in order to communicate with the device. Once connected the device will appear as an RS232 COM port on the system. Select the COM port in the SpectraView Preferences. SpectraView does not change any of the measurement settings on the device such as the standard observer setting, and measurement times. Be sure to set the observer setting to 2°.

Nvidia video drivers "No Communications":

• There is a known issue with the Nvidia video drivers versions 260.xx that prevents SpectraView from communicating with the display via DDC/CI. If you experience a "No Communications" error when using an Nvidia video chipset, try downloading and installing an older version (prior to 260.xx) of the drivers. Nvidia is aware of this issue and is expected to have updated drivers available soon. If you are using a MultiSync PA series display, please connect a USB cable from the host PC to the display to avoid this issue.

Video Graphics Adapter control panel "color controls':

• Some video drivers install control panels that provide some color controls such as gamma, brightness, contrast and even Video Media playback modes. These controls can interfere with the calibration process and should never be adjusted. Be sure the settings for these controls are reset to the "default" settings.

"An error occurred while communicating with the display monitor" message:

• In some rare cases the software may encounter errors when communicating with the display monitor. Try restarting the calibration. Also try updating the video card drivers if possible. If the issue continues please provide feedback using the form on the Sharp NEC Display Solutions SpectraView support page and include the display monitor model and serial number, video graphics adapter model, and OS version.

DICOM Calibration:

• If calibrating to the DICOM tone response curve, selecting the Calibration Priority: Best grayscale color tracking option in the SpectraView Preferences may result in a slight decrease in the DICOM response curve accuracy. If the greatest possible DICOM curve accuracy is required, please select the Maximize Contrast Ratio option.

NEC LCD2180WG-LED:

• Be sure to allow the display monitor at least 30 minutes to warm up before calibrating the display.
• Due to the unique wide color gamut of this display, colorimeter based calibration sensors such as the X-Rite i1Display V1 and V2 are not able to accurately measure some aspects of the display's color characteristics. It is recommended to select the Factory Measurement option for the Primary Colors Chromaticity Coordinates source option in the SpectraView Preferences.

Datacolor Spyder3 color sensors:

• The Datacolor Spyder3 color sensors have been tested with the following NEC displays and found to cause inaccurate measurements when measuring the color primaries:

LCD2690WUXi, LCD2690WUXi-2, LCD3090WQXi and LCD2180WG-LED, PA241W, PA242W, PA243W, PA271Q, PA271W, PA272W, PA301W, PA302W, PA311D, PA322UHD and PA322UHD-2 only

Large screen displays without SpectraView Engine:

LCD4020, LCD4620, LCD5220, LCD6520, M40, M40B, M40-2, M46, M46B, M46-2, P401, P461, P521, P551, P701, X431BT, X461UN, X462UN, and X461HB only

• The accuracy to which the Intensity can be calibrated when a relatively low value target Intensity is used (less than 150 cd/m²) will be lower than normal, which results in a large Delta-E value to be reported. This is due to the very large screen size, high brightness of the display, and the thermal effect of changing the screen brightness. The monitor may take several minutes after calibration to stabilize in Intensity. Selecting the Extended luminance stabilization time option in the Preferences can be used to minimize this issue.


• Some versions of these models do not support OSD Control Locking.


• Direct color calibration is not available when using the HDMI video input on some models. To calibrate the monitor, use the DVI input, then when completed change to the HDMI input and change the GAMMA SELECTION setting to PROGRAMMABLE on the On Screen Display.


• Direct color calibration is not available when using the DisplayPort video input. To calibrate the monitor, use the DVI input, then when completed change to the DisplayPort input and change the GAMMA SELECTION setting to PROGRAMMABLE on the On Screen Display.
