EIZO AND DISPLAY CAL

[joakim]

Hi,

I have an Eizo CG2700x, and I wanted to know if Display Cal is working with the selfcalibrator system of the Eizo? I have try but can’t find the instrument of calibration on main page.

Thanks for you help!

No.

Since it’s a hadrware-calibrated monitor, you should calibrate it with ColorNavigator, not DisplayCAL.

DisplayCAL is an app for software (GPU-level) calibration, which is simply inferior to hardware (monitor-level) calibration.

Hi Kuba,

Thank you very much for your quick answer !!

So, when using eizo, color navigator, then resolve, an ultra studio, there is no need to use display cal ?

No need for a 3d lut somewhere in the pipeline?

I have no idea, since I don’t do any video editing.

That colorimeter is not supported
https://www.argyllcms.com/doc/instruments.html
You’ll need and i1d3 colorimeter from Xrite calibrite (not colormunki display or display SL) to measure it with DIsplayCAL.

Also ColorNavigator7 does not support properly the i1d3 out fo the box for all new CG/CS displays using WLED PFS backlight, it is using a not portable (between diffenet i1d3 units) matrix correction (default) or a colorimeter correction clos to CS2730 (GB-LED) instead of WLED PFS.
Eizo APAC & community provided support for WLED PFS, just replace GB_LED correction file with one of the newer ones and then select on CN7 measurement for i1d3 “no compensation” (use EDR) instead of “color management” (matrix correction).

Reply To: Where can I find CS2731 EDR file?

Remember to set back “color management” as correction when you want to use CG2700X internal colorimeter (since it’s matrix correction is supposed to be taylor made and embeded on display)

You can use CN7 and your CG2700X lut-matrix-lut (1D LUT) to simulate rec709 in an “idealized/simplified” way:  assuming little to no volumen colorimetric errors in native colorspace.
Then run a verification report on DispayCAL with an i1d3 colorimeter, suitable CCSS colorimeter correction for i1d3 (text equivalent to EDR) and MS Windows using “simulate profile” and use “simulate profile as display profile” and your desired gamma settings and check how accurate is this simplified simulation. You can do the same on CalMAN/lightIllusion.
Usually on CG /CS models this 1d simulation is extremely good, contrary to what some misinformation intoxicators say online.

If you want a true LUT3D inside CG2700X you’ll need a i1d3 colorimeter to do it for free with DIsplayCAL.
-first of all remember what I said before about CN7, colorimeter corrections and such.
-calibrate using 1dlut your CG2700X (remember to use proper colorimeter correction for i1d3) to native gamut and target white and birghtness, no matter which gamma. for example: native gamut , D65 white, 100nit, g2.2
-after calibtrating, open DisplayCAL, choose suitable colorimeter correction (CCSS ewuivalent to whatever EDR you used on CN7), and create a XYZLUT “detailed” profile capturing all volume errors on native colorspace. With that XYZLUT ICC proifle you’ll create a LUT3D 17^3 iridas cube format that maps Rec709 g2.4 (source)  to native display colorspace (destination, your custom XYZLUT profile).
-Open CN7, got to the slot where you saved the calibration CALx slot you are using,  in Avdenced button there should be a “logviewlut” option, choose iridas.cube file you created previously and load it to monitor. (Go to CN7 user manual “LogView LUT Emulation”)
-use displaycal   “simulate profile” and use “simulate profile as display profile” (rec709 g2.4) to validate LUT3D calibration. You can use CAlMAN or lighillusion too, or even HCFR.

CN7 cannot create LUT3D by itself, but allows you to load LUT3D created with 3rd party software.

As a learning exercise try
-CAL2, HW calibration simulating (1DLUT) Rec709, D65 g2.4 100nit
-CAL3, HW cal, native, D65, g2.2 100nit on CAL3. Then after calibrating do DisplaYCAL workflow to create iridas cuve 17^3 LUT3D for that CLA3, load LUT3D into CAL3 logviewLUT.
-Validate both vs Rec709 g2.4

LUT1D errors should be extremely low (unless you messed up with colorimeter corrections in both apps CN//DisplayCAL) on both scenarios, less than 1dE until near black, since true black (ininite contrast) and near true black at gamma 2.4 are “out fo gamut” of your display (~1500:1)

Hi Vincent,

Thank you so much for your very detail answer !! It’s fantastic!

I don’t have now an i1d3, looking forward to have one for doing a true 3d lut.
When you talk about the I1d3, would  the Calibrite i1Display Pro working also ?
Meanwhile I  will do a 1D lut it with CN7.

Some questions if you don’t mind about the way of doing it properly, ony using the CN7, because I have done one calibration already but the white was a little bit warm in my eyes, compare also to the precalibrated eizo settings.

My goal is to have rec 709, 100 nits, gamma 2.4. It’s how I will work in output in Resolve.

On the traget page are you doing like that one these points :
-No using ICC
-Brightness 100 nits
-White point D65
-Priority Standard ? Or one of the two other options (gray balance, fixe gamma)?
-Gammut BT 709.    … Or native?
-Gammut clipping on, or off ?

Once the calibration is done, then there is an option after it with the cg2700x to do an extra color patch calibration.
Is it good to do it?

Then when it’s done on resolve, when passing through the ultra studio 4k mini, out to the Eizo with HDMI, it would be a clean signal, right?

Thank you so much !!

Best regards,

Joakim

Yes, xrite i1displaypro, xrite i1display pro oem, calibrite display pro, calibrite HL and HL plus. = “pro” i1d3, compatible with CN7. Remember that by defaukt CN7 does not supply a valid EDR colorimeter correction for modern CG/CS displays, it is still using CS2730 as reference. Explained on previous post.

Colormunki display / calibrite SL will be rejected by Xrite SDK (used by CN7) although they are i1d3 and work with DisplayCAL.

Also there is an hybrid approach. Use CN7 and internal probe to calibrate native gamut in CN7 100nit D65, then use i1d3 on DisplayCAL to create a LUT3D but there may be small whitepoint error due to different colorimeters&corrections. CCSS/EDR fro CG319X should be valid for all moderns CG models, even CS correction would do the job.
Also bundled correction with DIsplayCAL (HP Z24x G2 WLED PFS phosphor) should be close to your display since it uses same backlight type.

Meanwhile I  will do a 1D lut it with CN7.

Some questions if you don’t mind about the way of doing it properly, ony using the CN7, because I have done one calibration already but the white was a little bit warm in my eyes, compare also to the precalibrated eizo settings.

It may be colorimeter fault, user misconfiguration in CN7 (explained below), your own eyes/visual system not cose to CIE std observer 1931 2 degree…
Usually another good measurement device will point to the problem.

Last problem I named is solved with visual whitepoint adjustment to another reference “true d65” display in CN7 post calibration stage (“advanced functions button”), but use it as last resort.

My goal is to have rec 709, 100 nits, gamma 2.4. It’s how I will work in output in Resolve.

On the traget page are you doing like that one these points :
-No using ICC

IDNK what do you say. Anyway I woudl create ICC for OS so if you open a color managed app it would behave properly.

-Brightness 100 nits
-White point D65
-Priority Standard ? Or one of the two other options (gray balance, fixe gamma)?

Standard, no need to calibrate near black color of grey loosing a little contrast, you aim for video use

-Gammut BT 709.    … Or native?

Rec709 if you are using CN7 with internal probe and nothing else. This will make your CG2700X behave like a tre Rec709 monitor

Native only if you aim for photo use on color managed enviroment or want to create a LUT3D after using 3rd party software.

Sicne yo want to use it for Rec709 video (I assume) and you do not own an i1d3… first option is your only option right now.

But if you ware using macOS and Resolve, you may create a native gamut calibration, crete resulting ICC and in mac Resolve use “use mac profiles for Resolve”

-Gammut clipping on, or off ?

usually on if you are aiming to use as a non color managed Rec709 monitor

Once the calibration is done, then there is an option after it with the cg2700x to do an extra color patch calibration.

IDNK what you are saying.
If you mean “validation” stage, to test results usieng the same device used for measurng? yes, it’s an option, actually your only way to verify results right now
If you mean “advanced” option to visually match whitepoint because your measurement device and your eyes watching another reference monitor do not match… it depends. First of all make sure you used “color managed” (and not “no compensation”) on the screen where CN/ ask you what colorimeter to use white using CG2700X internal colorimeter, I ment to use factory matrix correction for that colorimeter and display.

Then when it’s done on resolve, when passing through the ultra studio 4k mini, out to the Eizo with HDMI, it would be a clean signal, right?

A basic test will be feeding Rec709 100% saturation test patches in RGBMY on a new resolve project. They should look “sRGB/rec709” in green/cyan maybe red, not the oversaturated native gamut.

Brillant, thanks !

I will work with theses tips

Thanks a lot
