Eizo Monitors

ColourSpace can be integrated with selected Eizo monitors for accurate Closed Loop display profiling and calibration.

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

The following are presently the only Eizo monitors with in-built 3D LUT capability:

  • CG222W, CG232W, CG242W, CG243W, CG223W, CG245W, CG275W, CG246, CG276, CG277, CG247, CG247X, CG248, CG318, CG279X, CG2700S, CG2700X, CG3145, CG3146, and CG319X

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

The CG232W has some limitations on monitor pre-set capabilities, but can still be calibrated as best possible with ColourSpace.

ColourSpace Integration

Eizo monitor operation and function is controlled via the Hardware Options menu, accessed via the Profiling window.


Initial Setup

Older Eizo monitors have fixed calibration slots, meaning you must have the correct input signal connected for the slot to be calibrated.

All newer monitors can have calibration slots programmatically set, regardless of the input signal type connected:

With ColourSpace, Eizo monitor calibration can be performed without any need for any additional software, and it is not recommended to use ColorNavigator at all, as it will potential compromise the calibration accuracy achievable.

  • If required, make sure the correct drivers are installed
    (If necessary, verify via Windows Device Manager)
  • Connect the Eizo monitor to the ColourSpace laptop via a network/USB connection, as well as a direct video connection with valid signal, and start ColourSpace
    (On older Eizo models, the connected video cable type will define the Cal slot ColourSpace will calibrate
    On newer monitors that can be programmatically set, the monitor's OSD can be used to select the slot to be calibrated
    Only select Cal slots can be user calibrated)
  • Using the Eizo on-screen menus configure the monitor as required, including Cal Slot, Signal Range, etc.
  • Open a ColourSpace Profiling window, and set the desired options via the Settings menu, as required
  • Select Eizo from the Hardware Options drop-down list, and select Connect
  • Select the LUT Processor type to be used from the Eizo Options menu - Extended should be used by preference
    (This option will be greyed-out and inaccessible if the monitor has only one option - which will be the displayed option)
  • The TPG Processor type can be selected via the Eizo Options menu - Emulated is the usual preference
    (This option will be greyed-out and inaccessible if the monitor has only one option - which will be the displayed option)
  • 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
  • Using the Calibration Patches option enable patches for profiling
    (If Custom patch sizes are available they are set via the ColourSpace Settings window)
  • Set the monitor's Peak Luma using the Interactive Controls while taking interactive measurements via the Manual Measure menu
    (The desired target value will depend on the accuracy of the white point colour temperature)

Potentially, when Unity Bypass data is Uploaded all monitor settings will be nullified. Should it be desired that different LUTs and other settings remain as defined, upload a real Bypass 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.

Calibration Limitations

Some Eizo monitors will not work correctly with YUV/YCrCb signal paths when using 3D LUTs, and must be set to RGB.
CG247, CG277, and CG267 have two 3D LUT locations - Standard and Extended. Extended is before the YUV to RGB conversion, and so will not work with YUV inputs. Standard is after the YUV to RGB conversion, and will therefore work with YUV or RGB inputs
CG247X has the Extended LUT only, before YUV to RGB conversion, and so will only work with RGB inputs. The LUT is also before signal scaling, and will require Video Scale to be applied to the LUT if using a Legal Range signal path workflow.

Additionally, Eizo monitors that use the Extended LUT option have the Standard TPG Processor after the LUT, and so cannot be used to verify calibration. If available, the Emulated TPG Processor should be used, as it is before the LUT.

Profiling Operation

To profile the Eizo monitor with ColourSpace navigate to the desired profiling mode - Manual Measure or Display Characterisation.

The screen of the Eizo monitor will mimic the colour displayed, using the patch settings defined via the Hardware Options and Settings menus.

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

Alternatively, an external TPG can be used.

  • Open a second ColourSpace Profiling window, select Hardware Options, and select the required TPG from the Hardware drop-down list
    (Refer to the relevant TPG User Guide for further operational information)
  • The probe must be connected to the same Profiling Window as the TPG

Any patch generator can be used for profiling, including direct HDMI/DVI/DisplayPort connection from the ColourSpace laptop.

From the Probes Options menu it is possible to select the internal Eizo Probe from the available probes list. ColourSpace will then use the internal probe for patch measurements. However, the internal Eizo probe is not very accurate, and we always recommend using a better quality external probe.

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 (if available), and Upload.

Depending on the settings used within the Eizo, and the signal path in use, LUTs may need to be pre-process via Video Scale before a LUT is uploaded for Legal Range workflows.

Note: Only select Cal slots can be user calibrated. If attempting to load a LUT into a slot that cannot be overridden an error message will be displayed stating the load failed.
