NEC Monitors

ColourSpace can be integrated with NEC's MultiSync monitors that use the SpectraView engine monitors for accurate calibration.

  • ColourSpace INF/XPT/PRO/CAL/LTE
  • Closed Loop Profiling
  • 3D LUTs
  • Inbuilt TPG Operation

The NEC MultiSync PA Series, some P series, and select large screen monitors that utilise the SpectraView engine, can be accurately calibrated via 3D LUTs generated using ColourSpace. The following are the only NEC monitors with in-built 3D LUT capability:

  • PA241W, PA271W, PA301W, P232W, P241W, P242W, P243W, PA231W, MD301C4, PA242W, PA243W, PA272W, PA271Q, PA302W, PA311D, PA322UHD, PA322UHD-2, MD322C8, X841UHD, X841UHD-2, X651UHD, X651UHD-2, X981UHD, X981UHD-2, X551UHD
  • (sRGB monitors P404, P484, P554, V404, V484, V554, V404-T, V484-T, V554-T, P654Q, V654Q, C651Q, P754Q, V754Q, C751Q, V864Q, C861Q, V984Q, C981Q)

ColourSpace Integration

NEC calibration is controlled via the Hardware Options menu, accessed via the Profiling window.


Initial Setup

  • If required, make sure the correct drivers are installed
    (If necessary, verify via Windows Device Manager)
  • Connect the NEC monitor to the ColourSpace laptop via a USB connection, as well as a direct video connection with valid signal, and start ColourSpace
    (If both a USB and HDMI connection are made to the monitor from the ColourSpace laptop there may be data connection issues, as some NEC monitors can be communicated to via the HDMI cable, as well as via USB)
  • Use the monitor OSD to select the Picture Mode you want to assign the 3D LUT to
    (Press the up/down buttons when no OSD is shown to select one of the 5 Picture Modes)
  • Set the desired set-up options via the Settings menu, as required
  • Open a ColourSpace Profiling window, select Hardware Options, and select NEC from the Hardware drop-down list
  • From the Serial Port menu select the connected NEC monitor ID
  • To make sure there is no existing calibration data active within the selected Profile/Load/LUT/Slot, and associated colour space selection, etc., select Unity Bypass from the Select LUT option, and press Upload
    (Or to keep things simple just select Preset #1 if you selected "Picture Mode #1" previously, etc.)

Note: Potentially, when Unity Bypass data is Uploaded all settings will be nullified, not just the relevant LUTs. Should it be desired that settings other than the LUTs remain as set, upload a real Bypass 3D LUT (generated via LUT Tools/LUT Management/New), as that will only null the relevant LUTs, as selected. Alternatively, reset any necessary settings, such as Brightness/Contrast/Black-Level, after the Unity Bypass data Upload.

To perform Brightness/Contrast/Black-Level changes use NEC's own MultiProfiler Software, using the "synchronise" function in MultiProfiler when switching from ColourSpace to MultiProfiler to force the re-reading all of the relevant settings that the ColourSpace Unity Bypass LUT will have changed.

Profiling Operation

While NEC monitors can be calibrated using ColourSpace via a LUT upload, the actual profiling must be performed via a an external patch generator.

Any patch generator can be used for SDR profiling, including direct HDMI/DVI/DisplayPort connection from the ColourSpace laptop. For HDR/HLG/Dolby Vision the correct metadata will be required within the video signal, requiring a dedicate TPG or metadata injector, unless the display can be forced into the required input format.
(Possible data connection issues when both a USB and HDMI connection are made to the ColourSpace laptop, defined above.)
Note: The keyboard 'O' key can be used within the Hardware and Manual Measure menus to quickly Disable/Enable the TPG.

LUT Upload

After profiling, a Calibration LUT can be generated as normal within ColourSpace LUT Tools.

With the LUT still held within ColourSpace navigate back to the Hardware Options menu, and select the desired LUT from within the Select LUT options, and Upload.
