NEC Monitor User Guide

LightSpace CMS can be integrated with NEC's MultiSync displays that use the SpectraView engine for accurate display profiling and LUT generation.

The following instructions are for calibration of the NEC MultiSync displays with LightSpace CMS.

NEC Displays with 3D LUT Capability

NEC Calibration

The NEC MultiSync PA Series, some P series, and select large screen displays that utilise the SpectraView engine, can be accurately calibrated via 3D LUTs generated using LightSpace CMS. The following are the present NEC display that can be calibrated via LightSpace.

  • PA241W, PA271W, PA301W, P232W, P241W, P242W, PA231W, MD301C4, PA242W, PA243W, PA272W, PA271Q, PA302W, PA322UHD, PA322UHD-2, MD322C8, X841UHD, X841UHD-2, X651UHD, X651UHD-2, X981UHD, X981UHD-2, X551UHD

Additionally the following sRGB displays also have 3D LUT capability.

  • P404, P484, P554, V404, V484, V554, V404-T, V484-T, V554-T, P654Q, V654Q, C651Q, P754Q, V754Q, C751Q, V864Q, C861Q, V984Q, C981Q

Any other NEC display should be assumed to not have 3D LUT capability, and we suggest checking with NEC directly before a display purchase is made if intending to calibrate accurately via LightSpace CMS.

Initial Setup

These NEC displays can be calibrated using LightSpace CMS via LUT upload, although the actual profiling must be performed via a an external patch generator, such as the HDMI/DVI/DisplayPort output from the LightSpace CMS PC - see below.

  • Connect the NEC display to the LightSpace PC via a USB connection, as well as a direct video connection (HDMI/DVI/SDI, etc), and start LightSpace CMS.
    (If both a USB and HDMI connection are made to the display from the LightSpace PC there may be 'data connection issues', as some NEC displays can be communicated to via the HDMI cable, as well as via USB)
  • Use the OSD to select the Picture Mode you want to assign the settings to.
    (Press the up/down buttons when no OSD is shown to select one of the 5 Picture Modes)
  • Navigate to File/Upload, and select the NEC option from the 'Select the device type' drop-down window.
  • From the 'Monitor' window select the connected NEC monitor ID.
  • If there is no LUT active with LightSpace the NULL Cube option will be ticked and greyed-out, but is operational.
    (As no other LUT is available the ONLY option is the NULL Cube)
  • Using the 'Select Preset' option select the desired display preset to use.
    (Or to keep things simple just select Preset #1 if you selected "Picture Mode #1" etc.)
  • To make sure no LUT is already active with the NEC display, and to re-set all other internal display calibration settings, select 'Upload', with the NULL Cube box ticked.
  • Close the 'Upload' menu.
NEC Upload

The Upload menu is located under 'File/Upload'.

Uploading a 'Null Cube' will re-set all the display parameters, so the Brightness/Contrast/Black-Level settings will need to set as per the Initial Display Set-up guide. To perform this use NEC's own MultiProfiler Software, using the "synchronise" function in MultiProfiler when switching from LightSpace to MultiProfiler to force the re-reading all of the relevant settings that LightSpace will have changed.

Null Cube

When the 'Null Cube' tick box is used, all display settings may be nullified, not just the 3D LUT. Should it be desired that display settings other than the 3D LUT remain as set, upload a real Null/Bypass 3D LUT (generated via File/New), as that will only 'null' the 3D LUT.

Although the option is labeled 'Null Cube', an actual Cube (LUT) is not necessarily loaded into the display, depending on the display's capabilities/options. A 'reset' command may be issued, rather than an actual Cube file uploaded.

Calibration Operation

As NEC displays do not have suitable in-built patch generation the direct HDMI/DVI/DisplayPort connection from the LightSpace laptop/PC will be used for patch generation during profiling, using the NEC display in extended desktop mode.
(See Direct HDMI for Display Profiling for further info - this is important to read before starting profiling!)
(Note possible data connection issues when both a USB and HDMI connection are made to the LightSpace PC, defined above.)

Profiling can then be performed as normal, using the probe connected to LightSpace, with the extended desktop displaying the patches via the normal LightSpace patch window.

Extended Desktop, with the left hand side being the LightSpace Laptop/PC, and the right hand side the display being profiled.

LUT Upload

After profiling a Calibration LUT can be generated as normal, and with the LUT held within LightSpace navigate back to the 'Upload' menu, and with the 'NULL Cube' tick box un-ticked, the present LUT displayed within LightSpace can be 'Uploaded'. The location to upload to is selected via the 'Select Preset' option, as described above.

Repeat the process for all the available profile slots, enabling quick LUT swapping via the display OSD controls and the 5 presets.
