Eizo Monitor User Guide

LightSpace CMS can be integrated with Eizo displays with 3D LUT capability for accurate display profiling and LUT generation.

The following instructions are for calibration of Eizo displays with LightSpace CMS.


Eizo Displays with 3D LUT Capability

Eizo Calibration

At the time of writing the following are the only Eizo displays with 3D LUT capability:
(This data is updated every time a new Eizo is released, if it has 3D LUT capability.)

  • CG222W, CG242W, CG243W, CG223W, CG245W, CG275W, CG246, CG276, CG277, CG247, CG247X, CG248, CG318, CG3145, CG319X, and CG232W

Note: Not all CG model Eizo displays have 3D LUT capability, with the CG2420 and CG2730 being two examples that lack internal 3D LUTs. Any other CG displays (or any other 'Series' of Eizo displays) not listed here must be assumed to NOT have 3D LUT capability.

Note: The CG232W has some limitations on display pre-set capabilities, but can still be calibrated as best possible with LightSpace CMS.

Additionally, the following (older) display models have fixed calibration slots, which means you must have the correct input signal connected for the slot to be calibrated:

  • CG222W, CG223W, CG232W, CG242W, CG243W, CG245W, CG246

The following (newer) display models can have calibration slots programmatically set, regardless of the input signal type connected:

  • CG275W, CG277, CG247, CG247X, CG248, CG318, CG3145, CG319X

Note: Communication with Eizo displays is not especially fast, so be patient when making menu selections within LightSpace.


LightSpace Calibration

Calibration of the Eizo CG range of displays with 3D LUT capability using LightSpace CMS is as follows, and may require the use of Eizo's own ColorNavigator XN software to enable Peak Luma to be pre-set, depending on the specific Eizo model you are calibrating.
(This may be required as Eizo displays have no 'normal' manual Brightness/Contrast controls.)

We do not recommend using ColorNavigator or the inbuilt probe for full calibration as the results are not at all accurate.

Before commencing with the below calibration procedure, check the Eizo display is set correctly for the input signal to be used, with a valid video signal being applied to the video input to be calibrated - paying specific attention to the required image range, Data or TV Legal, by making sure the correct Input Range setting is in use from the display's OSD menu. Use the Light Illusion CalImages for this, following the Display Calibration - Initial Set-up guide. Also make sure the correct Colour Space has been selected.

Note: Some Eizo displays will NOT work correctly with YUV/YCrCb signal paths when using 3D LUTs, and MUST be set to RGB.
If when attempting calibration the image shows 'strange' colour shift with a 3D LUT active in YUV mode, the display is one with this issue. Additionally some Eizo displays have the patch generator 'after' the 3D LUT, so cannot be used to verify the uploaded calibration.

Additionally, make sure to turn off any/all display automated re-calibration processes - they will attempt to overwrite your accurate calibration with inaccurate calibrations when you are not looking!


Initial Setup

Assuming the Eizo display is one of the newer models, all profiling and calibration can be performed with LightSpace, without any need for any additional software (ColorNavigator NX - although this can be used to check any of the Eizo's settings, as defined at the end of this page).

Eizo Upload
  • Make sure a signal cable is connected to the Eizo display, with a valid signal active
    (You cannot calibrate an Eizo display without a signal cable connected, with a valid active signal)
  • Depending on the Eizo model, the connected cable type will define the Cal slot LightSpace will calibrate
  • Alternatively, on displays that can be programmatically set, use the display's OSD to select the slot to be calibrated
  • Connect the Eizo display to the LightSpace PC via a network/USB cable, and start LightSpace CMS
  • Navigate to 'File/Upload', and select the Eizo option from the 'Select the device type' drop-down window

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

  • From the 'Select the Monitor id' window select or manually enter the Eizo monitor ID
  • If there is no LUT active within 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)
  • If available with the Eizo model being calibrated select the LUT type to be used - Standard or Extended
    Extended mode should be used by preference.
    (This option will be greyed-out and inaccessible if the display has only one option - which will be the displayed option)
  • To make sure no LUT is already active with the Eizo display, and to set to default/off any other of the displays calibration parameters, select 'Upload', with the NULL Cube box ticked
  • Using the 'Calibration Patches' option select Full to enable the internal Eizo patch generator
  • Close the 'Upload' menu
Eizo Brightness

The 'Options' menu is not really viable at this time, and can be ignored. But, as new Eizo models have greater capabilities added, this menu will expand to have additional options for Eizo calibration. For now, the 'Brightness' option it contains is better accessed via the Calibration Interface window, as it can be used interactively with Manual Measure to set peak luma.

  • Navigate to the 'Calibration Interface' menu, double click the small patch window to open the floating patch window
    (This will connect to the inbuilt patch generator within the Eizo)
  • Set 100% white, and select the 'Display Controls' option to open the Brightness control for Eizo displays
  • While taking Manual Measurements readings adjust the Brightness control the set the peak luma value to the desired level
    (Note: The desired target value will depend on the accuracy of the white point colour temperature, as if inaccurate the Calibration LUT will need to reduce the final value to correct the white point colour temperature)
  • When set correctly, close the Brightness window, and profiling can begin

Eizo Brightness


Profiling & Calibration

To activate the internal Patch Generator within the Eizo display navigate to the desired profiling mode - Calibration Interface, or Display Characterisation.

When the patch window is activate within LightSpace (the LightSpace CMS internal floating patch window has been made active by clicking the small colour display box when using Quick Profiling or Manual Measure modes) the internal patch generator within the Eizo display will mimic the colour displayed within LightSpace.

Profiling can then be performed as normal, using the probe connected to LightSpace, and with the Eizo displaying the required patches on the display screen.

Note, that from the Discoverable Probes menu it is possible to select the internal Eizo Probe from the available probes list. LightSpace CMS will then use the internal probe for patch measurements. However, the internal Eizo probe is not very accurate, and we would always recommend using an external probe, with the i1 Display Pro being the minimum we would recommend.


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 Cal slot the upload will be loaded into is defined via the video signal cable connection, as outlined above.

In this way, many different LUTs can be held within LightSpace CMS and quickly and easily uploaded into the Eizo display as needed, perfect for Look Management as well as accurate calibration to different standards.


ColorNavigator NX - Display Pre-set Configurations

For those Eizo displays that cannot use the 'Display Options' Brightness control within LightSpace 'ColorNavigator NX' should be used to pre-set the display peak Luma level
Note: Do not use any previous 'ColorNavigator' version as they use ICC profiles as well as being unable to adjust the Peak Luma level, as is need for Display Calibration - Initial Set-up. ColorNavigator NX for Windows can be downloaded HERE.)

  • Connect a signal cable to the Eizo display, with a valid signal active
    (You cannot calibrate an Eizo display without a signal cable connected, with a valid signal active)
  • Start ColorNavigator NX - this will cause the Eizo display to run through the different Colour Modes associated with the active input, so expect some 'flashing and banging' on the display's screen

Note: it is possible to run ColorNavigator NX on a PC that is separate to the system connected to the Eizo via the signal cable, but the ColorNavigator software is not really designed to operate like this... it will work, but will take some perseverance.

Depending on the Eizo model, if this is the first time any calibration has been attempted there will just be the display's standard pre-set colour spaces visible. To add a custom (Cal) colour space (Colour mode) follow the Eizo ColorNavigator NX user guide.
Depending on the model being calibrated the Cal slot (Colour Mode) used may need to match the standard default for the input type being used.
On older display models, usually Cal-8 is DVI input; Cal-9 is DisplayPort; Cal-10 is HDMI. On such Eizo models these are the only 'slots' that can be user calibrated. Newer Eizo models can have any 'slot' calibrated, including the factory pre-set 'slots'.
(Different Eizo displays have different Cal slot options - refer to the Eizo display's specific user guide for info).

  • Connect the Eizo display to the ColorNavigator NX PC via a network/USB cable
  • Start ColorNavigator, and select the correct Colour mode slot to match the input connection, as explained above
  • From within the 'Edit' menu Set the Brightness control (which is really Peak Luma) to the desired target (do not use the Min or Max options)

Note: Most of the following (excluding white point colour temperature) are set automatically when LightSpace 'Uploads' a Null Cube, but are included here form completeness.

  • Set Black Level to Minimum
  • Set White Point colour temperature to the desired value - D65 for example
    Note: this is optional, as the LightSpace calibration will correct it)
  • Set Gamma to the desired value
  • Gamma Priority should be set to Contrast, not Standard or Grey Balance
  • Finally, set Gamut to Monitor Native, and click OK
  • Select Adjust, and select the connected probe (preferably not the internal Eizo probe)
  • Place the probe on the centre of the display, click Next, followed by Proceed
  • Check the result values as displayed, and click Finish
  • Before closing, select Preferences and Other, and disable 'Use ColorNavigator NX Agent'
  • Quit ColorNavigator NX

The display, for the active input and selected colour mode, is now set to the desired Peak Luma, as well as potentially Gamma, White Point colour temp, and native Gamut.

Proceed with profiling and calibration as defined above.
