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:

  • CG222W, CG242W, CG243W, CG223W, CG245W, CG275W, CG246, CG276, CG277, CG247, CG247X, CG248-4K, CG318-4K, and CG232W

Note: The CG2420 does not use internal 3D LUTs, and neither do any other CG displays (or any other 'Series' of Eizo displays) not listed here.

Note: The CG232W is not compatible with ColorNavigator NX, making external calibration more difficult (see below for further information on why ColorNavigator NX is important). But the CG232W can still be calibrated as best possible with LightSpace CMS.

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


Initial Operation

Calibration of the Eizo CG range of displays with 3D LUT capability using LightSpace CMS is as follows, but does require the use of Eizo's own ColorNavigator XN software to enable Peak Luma to be pre-set, as the displays have no 'normal' manual Brightness/Contrast controls.
(We do not recommend using the ColorNavigator software for full calibration as the results are not as accurate as via LightSpace CMS.)

We also do not recommend the use of the internal Eizo Probe, again due to the results being inferior to an external probe, including the coast-effective i1 Display Pro.
(However, the internal probe when used with LightSpace CMS will provide calibration results superior to ColorNavigator...)

Before commencing with the below calibration procedure, check the Eizo 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 rang, Data or TV Legal, by making sure the correct 'Range extension' 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.

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!


ColorNavigator NX - Display Pre-sets

'ColorNavigator NX' should be used for all Eizo pre-sets - not 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.

ColorNavigator NX should be used to pre-set the Peak Luma for the display input port to be used, as well as potentially setting the desired White Point as this will limit any change in Peak Luma after final calibration, necessary if the actual display white point is significantly different to the target white point.

  • 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.

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.
Usually Cal-8 is DVI input; Cal-9 is DisplayPort; Cal-10 is HDMI, and on some Eizo models these are the only 'slots' that can be user calibrated. Other 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)
  • Set Black Level to Minimum
  • Set White Point to the desired value - D65 for example
  • Set Gamma to the desired value
    (This should ideally be slightly higher than the intended final value to prevent clipping)
  • 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 Gamma, White Point, and native Gamut.
(We have seen some difference in the value reported by ColorNavigator NX and LightSpace CMS with the same probe, but the differences are not really large enough to worry about, but do show the greater accuracy of LightSpace CMS.)


LightSpace CMS - Display Calibration
  • Make sure the same signal cable is connected to the Eizo display, with a valid signal active, as above
    (You cannot calibrate an Eizo display without a signal cable connected, with a valid signal active)
  • The connected cable type will define the Cal slot LightSpace will calibrate, so make sure this matches with the Cal slot pre-set with ColorNavigator NX as above
  • 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
  • From the 'Monitor id' windows 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)
  • To make sure no LUT is already active with the Eizo display select 'Upload', with the NULL Cube box ticked
  • Using the 'Calibration Patches' option select Full to enable patch display operation
  • Set the available Standard/Extended drop-down option as required, depending on the display and signal path configuration
  • Close the 'Upload' menu
Eizo Upload

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


Calibration Operation

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, such as the i1 Display Pro.


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.
