ColourSpace can be integrated with selected Eizo displays for accurate Closed Loop display profiling and calibration.
- ColourSpace Integration
- Closed Loop Profiling
- Inbuilt TPG Operation
The following are presently the only Eizo displays with in-built 3D LUT capability:
- CG222W, CG242W, CG243W, CG223W, CG245W, CG275W, CG246, CG276, CG277, CG247, CG247X, CG248, CG318, CG279X, CG3145, CG3146, CG319X, and CG232W
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.
The CG232W has some limitations on display pre-set capabilities, but can still be calibrated as best possible with ColourSpace.
Eizo display operation and function is controlled via the Hardware Options menu, accessed via the Profiling window.
The following (older) displays have fixed calibration slots, meaning you must have the correct input signal connected for the slot to be calibrated:
- CG222W, CG223W, CG232W, CG242W, CG243W, CG245W, CG246
The following (newer) displays can have calibration slots programmatically set, regardless of the input signal type connected:
- CG275W, CG277, CG247, CG247X, CG248, CG318, CG279X, CG3145, CG3146, CG319X
With newer Eizo displays all profiling and calibration can be performed with ColourSpace, without any need for any additional software (e.g. ColorNavigator NX).
- Connect the Eizo display 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 displays that can be programmatically set, the display's OSD can be used to select the slot to be calibrated)
- Open a ColourSpace Profiling window, select Hardware Options, select Eizo from the Hardware drop-down list, and select Connect
- If available with the Eizo model being calibrated select the LUT 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 display has only one option - which will be the displayed option)
- To make sure there is no existing calibration data active within the display, 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 display'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)
As soon as a Calibration Patches selection is made the Eizo display will show the patch colour as defined within the ColourSpace Manual Measure menu.
Potentially, when Unity Bypass data is Uploaded all display 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.
Some Eizo displays may 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/YCrCb 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.
To profile the Eizo display with ColourSpace navigate to the desired profiling mode - Manual Measure or Display Characterisation.
The screen of the Eizo display will mimic the colour displayed, using the patch settings defined via Hardware Options.
Profiling can then be performed as normal, using the probe connected to ColourSpace, and with the Eizo screen displaying the required patches.
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 would always recommend using a better quality external probe.
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 it.
