    “Then you can skip the LUT3D part, Just use CN fro calibrating but if you use an i1d3 with CN, make sure you swicth GB-LED EDR for the proper one for your display backlight.’

    Which is the LUT 3d part to skip? Do you mean tu just made a siftware calibration insrwad of a HW one?

    So can I switch proper backlight option on CN? Should not it make that autimatically afrer colorimeter choice?

    “But i1d3 with proper correction will be better than built in probe / munki spectro if you wish to measure a 3d mesh with thousands of patches…because it”

    Which is the part about how to make a proper correction of calibrite colorimeter in your post?

    Reply To: Eizo cs2420 uniformity

    Vincent ‘-15% is expected even on an Eizo…” you meant also for the cg series? If I am right mine has max 10% so inside the tollerance…is it right?

    I’m ask that because belong the instrument reading i see like a sort of reddish halo especially when the black is total on the upper left corner… waht o mean is that visually it doesn’t look so perfect just spannometrically speaking but maybe it’s because of my too hight expectation or due to the polarizing film but.

    I would just to be sure it was just my suggestion before the 15 day return period expired.

    uniformity off (DUE brightness) => extremely low dC errors on uniformity test
    for brightness uniformity you’ll need to activate it.

    DisplayCAL uniformity test (or other app) do not include backlight leaks on black screen (bleeding)

    it bleeding bothers you activate uniformity compensation, check contrast and if black level suits your task check bleeding again. It you donot find it acceptable for your task return the display.

    Rgarding the limits of the internal probe, wouldn’t it be worthwhile for eizo to stop including it by lowering the price and instead work to make it easier to implement the external ones uf thar works better? I find it wrong to sell the top range for 3000 euros and then force the customer to jump through hoops to understand even just the actual contrast level of what he has purchased.

    CG2420 and CG2730 built in probes are… non functional, at least at practical level. AFAIK you can use them for calibrating but you cannot use them for verifying even using CN (unless latest versions fo CN changed it). Also they are supposed to be lower spec’ than CG-X counterparts.

    CG-S/-X are functional for CN use. Other GNU apps do not support it because AFAIK Eizo has not published a public SDK to do that.

    I took eizo exactly because it is the only one to provide a complete bundled software for free but now I realize that the cumbersome DIY is also necessary here.

    With a CG-X no, you can use CN and expect to be ok.

    With widegamut CS, it is a shame that Eizo does not update CN to include poper EDR si no DIY action woul be needed (gettig the EDR).
    With CG-X the same if you use a i1d3, but custom LUT3D upload through 3d apps (EIZO apac tutorial for 3dLUT uploading) seems justified since lut3d calculation is out of scope of CN.

    The only reason to get an Eizo CG on 2022-3 (CG2420/CG2730), I meant a non CGS-CGX, is that you actually need 1500:1 but you do not have the budget for an -X / -S (or the need of a LUT3D)

    I’ m goung to do the measurements and reading by displaycal as you suggested but surely it would be a long story, hoping in your cooperation to reach that this matter is so damn hard to me!

    As explained previosuly, if you use built in probe:
    -calibrate with CN and internal probe with default colorimeyter correlation… that’s all. Done. Use it.
    -Validate results (all simulation profile options turned off) with DisplayCAL and 3nm mode (i1studio/i1prox spectro) or bundled HP Z24x G2 CCSS (or the ones provided by Eizo APAC) for i1d3 colorimeter
    There may be a mismatch between built in probe white point and the one measured by xrite probes, but grey must be neutral and PCS color coordinates should be in place.

    If you want to use your munki photo/i1studio/i1prox spectro… I would not advice for that, it will measure at 10nm with Eizo software. But test the dirft between 10nm mode and 3nm mode to see the error with your spectrophotometer.

    If you want to use an i1d3 colorimeter:
    -just replace GB-LED EDR with “forged” GB-LED EDR from EIzo APAC (it stores WLED PFS backlight)
    -on CN preferences choose “no compensation” for colorimeter (to make use of EDR).
    -that’s all, use it like explained with internal probe.

    The only “DIY” that is needed is when using i1d3 probe since CN has no correction for it and newer Eizo monitor (blame them through support request).

    “Then you can skip the LUT3D part, Just use CN fro calibrating but if you use an i1d3 with CN, make sure you swicth GB-LED EDR for the proper one for your display backlight.’

    Which is the LUT 3d part to skip? Do you mean tu just made a siftware calibration insrwad of a HW one?

    EIZO APAC tutorial videos, skip them. Just use CN for calibration, you do not need a full LU3D calibration for your tasks.

    So can I switch proper backlight option on CN? Should not it make that autimatically afrer colorimeter choice?

    It has no correction for i1d3. Explained abobe. Gte it from the link, replace correction. Set CN to use “no compensation” (whcih actually means using EDR).

    “But i1d3 with proper correction will be better than built in probe / munki spectro if you wish to measure a 3d mesh with thousands of patches…because it”

    This about creating an ICC profile with thousands of patches to make a LUT3D. It’s easier to do it with an i1d3 since that colorimeter is very fast has it is supported by 3rd party SW like DisplayCAL.
    Since you do not need it, skip that part.

    Which is the part about how to make a proper correction of calibrite colorimeter in your post?

    Creating EDRs for CN is waaaaay out of scope given your current “expertise level”. Just get one EDR made by others: Eizo APAC link from Lift gamma gain forum for example.

    Creating a CCSS correftion in DisplayCAL  with your color munki spectro is done thrugh Tools, correction, create colorimeter correction, choose “spectral” type. After it finishes share it with community so CG2700X owners without an spectrophotometer can use it with their i1d3 colorimeters.

    hi vincent. I tried the link https://www.liftgammagain.com/forum/index.php?attachments/eizo-cs-only-edr-and-ccss-zip.9782/ I registered but it says ” You do not have permission to view this page or perform this action.”

    however, I finally managed to reinstall the colormunky with the argyl drivers by uninstalling the originals and finally display cal recognizes it I checked the contrast and it is:

    1168:1 colormunky photo while with tcalibrite colorimeter  is 1215:1

    Now because CN7  gives me a contrast reading of 1459:1 and eizo only considers that as a reliable value it seems to me a scam., that’s because on photography forum where most of people are not colour expert like you people tendo to trust in the reliability of a big brand like EIZO

    You are an expert and you know that the integrated probe is less reliable than the external probes  but i can’t think they don’t know this at eizo! If I pay for a 1450:1 contrast I pretend it’s real, if the software of a 3,000 euro 27″ monitor claims the contrast is 1459:1 I pretend it’s true.

    1215:1 is les then  contrast measured on the viewsonic vp2786 by displaycal , of course it has inferior software (but even the eizo one doesn’t seem perfect from what you tell me) and poor uniformity but it costs 1/3. I would expect that even if it doesn’t meet the requirements of a “colorist” like you, a brand like EIZO doesn’t “cheat” on the plate values by declaring a 20% more contrast as BENQ does with its 600:1 against 1000: 1 measured (and in that case the uniformity correction is not even deselectable so evend more dishonest)

    . Again if I measure the white balance from the cal display I read 6168K and 119 cd /m2 against the D65 and 120 set on CN7 while if I  take a reading with the colormunkyphoto  I get 6664K but 111 cd/m2

    I don’t want to give up but I’m very discouraged .

    SPD, EDR, “forged”CCSS …APAC “Your world” is really complex for a person who does and has studied something else in life (I’m a graduate nurse) Lots of acronyms and acronyms of which I struggle to find the meaning even by googling and once I understand what the acronym means I still don’t understand what we are talking about and this is frustrating for me also because I have not found any tutorials or books that explain it and unfortunately I don’t know anyone who can help me personally. even the colorimeter names are complicated colormunky display is completely different from colormunky photo as well as i1display is same as i1d3 or colorchecker display but different from i1studio etc.etc.

    I really appreciate your kid availability as well as the possibility of using a very complete software for free. I love socialism, sharing and in this world everything is market and commodity exchange, I think of the expensive price of chromix, of calman, of the absolute indifference of xrite or eizo every time i asked for advice. you   are a rare  think and thank you so much for knowing and time  that you gift to the people.

    Hwello. I have a brand new calibrite plus that should be the same of xrite i1d3(isn’t it?) Is so hard to get an Edr/css even of not a color expeet like me?

    If you meant creating a CCSS it is in DIsplayCAL tools menu. Colorimeter correction, spectral correction, then allow displaycal to share ot via web.

    If you meant using proper EDR with CN:

    https://www.liftgammagain.com/forum/index.php?attachments/eizo-cs-only-edr-and-ccss-zip.9782/

    Withs is WLED PFS for CS2731 (registration needed), CG319X sample should be in that forum too. If your CG2700X is a WLED PFS LED it will be close to yours.

    Close CN, Replace EDR file (make backup of origibnal RG_phoshor EDR), run CN and on preferences choose the option “no compensation” to use EDRs with i1d3.
    Default “color management” value is a 3×3 matrix that is not portable between i1d3 units.

    For displayCAL just load the CCSS in that zip file or just import bundled set of corrections (HP Z24x G2 is teh one for WLED PFS phosphor with adobeRGB green).

    I found  the follow link this google drive link https://www.liftgammagain.com/forum/index.php?threads/eizo-apac-calibration-and-workflows-support.16640/ but if I understoon right it should be for CG2420

    and ” The X and S both have superior black level performance than the CG279X, very similar to the CG319X. Both have fantastic uniformity and calibrate extremely well, either with CN7 or Colourspace, and DCal through the same method I showed in the CG319X/279X How To video.” but probably it is for CG2420

    Explained before, register on that forum,  not going to repeat it again.

    however, I finally managed to reinstall the colormunky with the argyl drivers by uninstalling the originals and finally display cal recognizes it I checked the contrast and it is:

    Just happens that it seems that you do not understand what i wrote on previous messages regarding low light readings. If device is accurate on white & primaries, then built in probe is fine.

    You are an expert and you know that the integrated probe is less reliable than the external probes  but i can’t think they don’t know this at eizo! If I pay for a 1450:1 contrast I pretend it’s real, if the software of a 3,000 euro 27″ monitor claims the contrast is 1459:1 I pretend it’s true.

    It is not about price… it’s about physics. Think about it, the size of lens for low light readings on each device.

    1215:1 is les then  contrast measured on the viewsonic vp2786 by displaycal , of course it has inferior software (but even the eizo one doesn’t seem perfect from what you tell me) and poor uniformity but it costs 1/3. I would expect that even if it doesn’t meet the requirements of a “colorist” like you, a brand like EIZO doesn’t “cheat” on the plate values by declaring a 20% more contrast as BENQ does with its 600:1 against 1000: 1 measured (and in that case the uniformity correction is not even deselectable so evend more dishonest)

    Uniformity is about Quality Control, QC is about statistics. “Mean unit” Benq SW-C is 600:1 garbage. “Mean unit” Benq SW is uniformity 3-4dC garbage. “Mean unit” in VP widegamut is about >4dC.

    And QC is to be payed. It’s an statistical way of removing lower percentiles.

    Of course you can play lottery, but it is not a sensibe way of investment even there is one winner… between a million players.

    . Again if I measure the white balance from the cal display I read 6168K and 119 cd /m2 against the D65 and 120 set on CN7 while if I  take a reading with the colormunkyphoto  I get 6664K but 111 cd/m2

    CCT is meaningless, educate yourself about what white point is. Andrew Rodney had a PPF on his web, wikipedia has a nice graph too. CCT value (kelvin) is meaningless.

    when you understand what whitepoint is you’ll stop posting that knid of useless data. Displaycal dos not give you CCT values “alone” it add “a numerical surname”… and that’s for a reason. There are many threads around here about the same topic. Boring to write it over again an again… specauilly when even english wikipedia explains it.

    I don’t want to give up but I’m very discouraged .

    I think that you just do not understand what we wrote…

    SPD,

    spectral power distribution

    EDR,

    binary format for CCSS, Xrite propietary. apps taht use SDK dfrom Xrite use EDRs

    “forged”CCSS

    nope. EDR is teh one that need to be forged becase EIzo do not bundle WLED PFS EDR. CCSS are open… and we have one ready to use on DisplayCAl install.

    …APAC

    This is just you unable to use google. Eizo asia pacific. Stuart Pointon working for them actually, he is the one that created the custom EDR.

    If you had spent your time reading CS2731 thread in Lift gaimma gain before wasting others time… it wil be easier for you to understand the names & concepts.

    “Your world” is really complex for a person who does and has studied something else in life (I’m a graduate nurse) Lots of acronyms and acronyms of which I struggle to find the meaning even by googling and once I understand what the acronym means I still don’t understand what we are talking about and this is frustrating for me also because I have not found any tutorials or books that explain it and unfortunately I don’t know anyone who can help me personally. even the colorimeter names are complicated colormunky display is completely different from colormunky photo as well as i1display is same as i1d3 or colorchecker display but different from i1studio etc.etc.

    but that complexity you name is false. it is your imagination (or lack of skill).

    if you had an i1d3

    -get the “custom” EDR (register on the forum)
    -replace EDR file with the custrom
    -say to CN that you want to use EDR (IT’S IN THE CN7 MANUAL!!!)
    (the above just needs to be done ONE time)
    -calibrate
    -done
    (the two above are what you’ll be doing reguraly)

    if you want to use bult in probe… just use CN. Done.

    I really appreciate your kid availability as well as the possibility of using a very complete software for free. I love socialism, sharing and in this world everything is market and commodity exchange, I think of the expensive price of chromix, of calman, of the absolute indifference of xrite or eizo every time i asked for advice. you   are a rare  think and thank you so much for knowing and time  that you gift to the people.

    Explained before, register on that forum,  not going to repeat it again.

    answering to your “?”In the final part of my post I just said you thankyou fr sharing and your time and I said that it is awesme to see a free software like display cal even betetr of most of priceless softwere out here.

    I created an account as you said and when try to  opening your link   website say ” You do not have permission to view this page or perform this action.”

    I found a google drive file inside the forum shared from stuart pointed user called RG_Phosphor_Family_25Jul12_CG319X but I am not sureit is the one you meant and it is the right one i guess yes.

    Even if I found probably the right file can’t spot any EIZO CN7 folder any EDR file(neither serch in as *.edr in windows10) so i do not know how or where to replace it

    I watch enterely this video too, very clear and well explained but it is for resolve/video users and from the half of the video i get lost(i never used resolve and any other video software)

    i found also that but I comletely ignore what is https://github.com/ypomortsev/ccss2edrpubblicit

    but that complexity you name is false. it is your imagination (or lack of skill).

    Surely it is a lack of skill, even if you think these things are easy to understand for a person like me it is not easy at all. Maybe you take trivial things for granted and that’s also why it seems even more difficult to me than it is? Probably if I had to explain something about my work to you without having certain basics it might seem complex to you or maybe you have a much higher than average IQ and you would understand everything without problems I don’t know, I consider myself a normal person but as I said very inexperienced.

    for example:

    -get the “custom” EDR (register on the forum)

    -replace EDR file with the custrom

    could I continue to use the built in sensor when needed after replacing that file? I ask that because you said me to keep a backup copy of the original one

    -say to CN that you want to use EDR (IT’S IN THE CN7 MANUAL!!!)

    Why in your opinion eizo do not natively put this file in its software and then make “official”guide on youtube to “hack” its own software?

    (the above just needs to be done ONE time)
    -calibrate ( do you mean calibrate with display  CN7 + calibrite display plus isn’t it??)
    -done

    I understood that with this kind of file I could use display cal instead of CN7 to get a more accurate calibration(moretarget) and more option like gamut but probably it would me even more triky

    however, I finally managed to reinstall the colormunky with the argyl drivers by uninstalling the originals and finally display cal recognizes it I checked the contrast and it is:

    1168:1 colormunky photo while with tcalibrite colorimeter  is 1215:1

    Now because CN7  gives me a contrast reading of 1459:1 and eizo only considers that as a reliable value it seems to me a scam., that’s because on photography forum where most of people are not colour expert like you people tendo to trust in the reliability of a big brand like EIZO

    Just happens that it seems that you do not understand what i wrote on previous messages regarding low light readings. If device is accurate on white & primaries, then built in probe is fine.

     

    It is not about price… it’s about physics. Think about it, the size of lens for low light readings on each device.

    Sorry vincent but if I understood what you mean built in sensor on my eizo is too small to read  low dark so black value readin is not accurate.

    In my opinion if a data is not correct for physic reason eizo should simply do not put this data in its calibration report.

    Me and probably most people that are not experienced in those technical question just trust it…You could think I am stupid ad ignorant but I am pretty sure that if a photographer and not a colorist or an engeneer buy a display just trust what he read and if it is false is not a fault f physic but just a misleading advertising.

    If I dispute with  EIZo customer service  that contrast ratio is different from that what they ( and seller)claim they just ask me for calibration report with built it sensor and if inner sensor sai 1450:1 the say its fine even if the (true) value from display cal say 1200:1 in my opinion it is not physic but uncorrect business claim.

    Thank you again and   sorry if I’ve irritated you or if you think it’s wasting your time or that I don’t follow your advice, i do my best.

    regards

    EDIT:

    I found the folder under C:programdata and  rename the file edr  i got from googledrive folder on Liftgammagain

    https://www.liftgammagain.com/forum/index.php?threads/eizo-apac-calibration-and-workflows-support.16640/#post-163870

    of course deleting the old one(i kept that as you suggested in a separate folding as backup)

    Finally  i startt CN7  set on–preference–no compensation   and start a calibration by calibrite colorimeter.

    Attached  result from eizo software

    I also tried to do a verification from display cal and the same colorimeter putting  and  surely I did something wrong because overal  report is no good as CN7 expecially on white point (i woulod say “assumed 6400K” is a wrong software setting   but i do not want be scolded again as)

    I created an account as you said and when try to  opening your link   website say ” You do not have permission to view this page or perform this action.”

    Works fine for me. Please visit the said website as if you wanted to post to their forums. Make sure the website “thinks” you’re logged in. You should see your name in top right. If you don’t log in, tick “stay logged in” for extra assurance. Download the file after that. You can search that website for eizo-cs-only-edr-and-ccss-zip, it will send you to “EIZO CS2731 – Calibration issues” topic, in 1st page of three you will find that file attached. Can download by clicking the link there.

    I found a google drive file inside the forum shared from stuart pointed user called RG_Phosphor_Family_25Jul12_CG319X

    That’s the one I shall need once/if I end up buying that CG2420 I’m craving 🙂
    It is quite possible that it’s very similar to the one Vincent advised to you.

    Even if I found probably the right file can’t spot any EIZO CN7 folder any EDR file

    Can’t help until I get my monitor and software and that will probably be in a couple of months still. From reading Stuart’s messages on that forum the old file seems to be I found a google drive file inside the forum shared from stuart pointed user called RG_Phosphor_Family_25Jul12_CG319X.edr

    could I continue to use the built in sensor when needed after replacing that file? I ask that because you said me to keep a backup copy of the original one

    Taking a backup is part of doing the job well. I work in IT. Taking backup before replacing a file is just a good everyday practice engrained into my brain.
    I don’t know if CN uses that file when working with built-in colorimiter.
    And it is not very intersting to me if it does so.

    i1d3 is a better tool: it’s bigger, you can position it in the centre of the screen, Stuart and many other people using $6k-$12k tools have confirmed that paired with a close enough EDR file it becomes very precise. Why would you go back the built-in probe? Same Stuart with his hyper-expensive tool and tons of experience does not advise us to use it.

    Why in your opinion eizo do not natively put this file in its software

    Good question. They should have.

    I understood that with this kind of file I could use display cal instead of CN7 to get a more accurate calibration(moretarget) and more option like gamut but probably it would me even more triky

    Nope, you can’t use EDR file with DisplayCal. You can use CCSS files with DisplayCal. Stuart’s zip file includes two presumably equivalent files and .edr and a .zip
    Alternatively as Vincent suggested you could use one of CCSS files that comes pre-installed as part of DisplayCal.

    The story is this.

    Level 0

    Use CN to calibrate your monitor, e.gl. load settings into it. That will change how the monitor behaves. Make it more precise.
    Best if you can use i1d3, the EDR file from Stuart and use “no compensation” setting.
    Please go ahead and do it, that is reasonbly simple.

    Level 1

    Then you could use DisplayCal to “stody” the result. To characterize the monitor. That is called “profiling” and results in an ICC “profile” file. If installed correctly in Windows that ICC file will tell Photoshop how to feed color into that display.

    However as you noted this is extra work and extra complexity. It is up to you if you want to go for the trouble.
    DisplayCal indeed has many options which one needs to wrap head around.

    Notably this will make any change to display gamut.

    Level 2

    DisplayCal could potentially do more. It could make your graphics card alter number before pumping them out to display. Probably. Possibly depending on video card you’re using. I’m not sure. You see I am a novice as well. And I am not going to be using my monitor for photo work that much. I am just not going to do level 2. Both because I don’t need it and because I am same as you scared of doing it 🙂 Also the video card is talking to the monitor in 8 bits doing this heavily can result in banding. Not good.

    I am going to do other things instead of level 2 but they will be very specific to using DaVinci Resolve and I guess you’re interested in them very much in them

    You could think I am stupid

    Don’t worry I feel stupid all the time too. I’m a programmer. I quite technical. My interest in DisplayCal dates back many years. Yet I’ve felt rather intimidated until now and only this year after days and days and days of reading I’m feeling I’ve started to piece a picture together.

    1450:1 the say its fine even if the (true) value from display cal say 1200:1

    You still have a monitor in your hands which is way better than what most people use to do video/photo. It’s still got a better contrast than almost all of LCD monitors. In my view you have received your money’s worth.

    EDIT:

    I found the folder under C:programdata and  rename the file edr  i got from googledrive folder on Liftgammagain

    As I said that is the file for CG2420, but in practice it may be close enough. You’re still welcome to obtain the other file too.

    I also tried to do a verification from display cal and the same colorimeter putting  and  probably I did something wrong because overal  report is no good as CN7 expecialy on white point

    So right there in your screenshot there is “spectra correction”.  That is the CCSS file. I am not sure how well that file fits your monitor. Further to ensure best agreement between CN and DisplayCal you could obtain the .zip from the named forum. The .zip will have two files: one .edr and one .ccss. You can use EDR for CN. and CCSS for DC. Then I would expect that both programs will start looking at the monitor with the same eyes and calibration done by CN will look better in DC.

    thank you so much for your kind reply Atagunov

    As for the history of the contrast I agree with you, the values are excellent and for my needs it is surely  “too much” and I will be fine for the next 10 years (for the previous 10 years I had a prosumer S2232W  eizo and it still works great!

    However, I think it not very serious that a brand like EIZO “imposes” the purchase for its professional series, leaving one to think that CG offers something “extra” and  then come to know from the experts that that same probe is not able to read accurate value on the low lights as an amateur device like the calibrite manages to do better. They could offer the option to purchase the builtin probe or not or make that bigger or i do not know but surely they should  provide truthful  report throught they reputable CN7

    I repeat if you contact EIZO Italy they will reply that they ONLY consider the measurements taken with the integrated probe, so they wrote to me.

    Speaking about EDR I’ll try to recover that file perhaps by creating a new account on the other site and I’ll try to validate by  displaycal as you told me in the meantime let’s see what Vincent will say hoping he isn’t tired of putting up with me.

    Finally I thought it’s funny, a couple of days ago a self-styled colorimetry expert on an Italian photography forum (he writes reviews for eizo and organizes paid workshops) wrote to me, I paste verbatim just translated

    “but why don’t you want to use the internal colorimeter?! As I explained to you before, it has an additional correction linked to the parameters measured with a KLEIN directly in the factory. Then it is absurdly comfortable with the self-calibration.” you just wrote me “Why would you go back the built-in probe?…”   and  made me smile.(actually  because I ve just replaced the EDS file about xrite sub folder in CN7  I guess it do not have any consequence on builtin sensor  behavior

    Thanks again for your support and words of encouragement 🙂

    PS

    the file EDS I used should be for CG319X so according with what I read the most similar to  2700X 2700S

    Explained before, register on that forum,  not going to repeat it again.

    answering to your “?”In the final part of my post I just said you thankyou fr sharing and your time and I said that it is awesme to see a free software like display cal even betetr of most of priceless softwere out here.

    I created an account as you said and when try to  opening your link   website say ” You do not have permission to view this page or perform this action.”

    I found a google drive file inside the forum shared from stuart pointed user called RG_Phosphor_Family_25Jul12_CG319X but I am not sureit is the one you meant and it is the right one i guess yes.

    Even if I found probably the right file can’t spot any EIZO CN7 folder any EDR file(neither serch in as *.edr in windows10) so i do not know how or where to replace it

    I watch enterely this video too, very clear and well explained but it is for resolve/video users and from the half of the video i get lost(i never used resolve and any other video software)

    i found also that but I comletely ignore what is https://github.com/ypomortsev/ccss2edrpubblicit

    CG319X uses the same kind of backlight , although that “forged file” does not include the same exact padding as CS2731 to be a “copy” of GB-LED EDR, jus chaning spectral data.
    Anyway Stuart said that CN7 does not reject it in that thread.

    Regarding CS2731 edr file I can download it. Justa few seconds ago. Maybe you did something in your forum account so it is thinking that you are a neewly registered bot. Id problema persist I think Stuart won`t mind if i reupload it to 1fichier.

    CN folder was explained in almost all CS threads here, but:
    C:\ProgramData\EIZO\Sensor\i1DisplayProEDR

    As you can say… path is telling you everything you need to know about what is stored there.
    WLED is CS2410 (sRGB)
    WCCFL are very old CCFL backlight way before CG275W
    GB-LED is the backlight used in al coloredges till CS2731/CS2420 and CG247x/CG319X

    The hack replaces GB-LED data with WLED PFS phosphor data. That’s all.

    but that complexity you name is false. it is your imagination (or lack of skill).

    Surely it is a lack of skill, even if you think these things are easy to understand for a person like me it is not easy at all. Maybe you take trivial things for granted and that’s also why it seems even more difficult to me than it is? Probably if I had to explain something about my work to you without having certain basics it might seem complex to you or maybe you have a much higher than average IQ and you would understand everything without problems I don’t know, I consider myself a normal person but as I said very inexperienced.

    for example:

    -get the “custom” EDR (register on the forum)

    -replace EDR file with the custrom

    could I continue to use the built in sensor when needed after replacing that file? I ask that because you said me to keep a backup copy of the original one

    -say to CN that you want to use EDR (IT’S IN THE CN7 MANUAL!!!)

    Why in your opinion eizo do not natively put this file in its software and then make “official”guide on youtube to “hack” its own software?

    There is no official guide on youtube for the hack. You had misunderstood everything.

    YOutube guide is to use CG-X LU3TD calibration characteristics. CN allow you to import 3rd party LUT3D, by default it uses lut-matrix-lut pipeline in its HW calibration.

    What youtube guide teaches is how to create such LUT3D with DIsplayCAL, lightillusion software or calman.

    The hack is not related at all with that stuff… an nodoby pointed that. It just you misunderstanding everything. The hack is about colorimeter correction for i1d3… hich is the one missing. Also in NEC, Dell, LG, Asus  Benq tghe EDR for WLED PFS is missing (and QLED is missing too for Asus and Benq). Why?… likely to be Xrite royalties that these companies do not want to pay.
    But since EDRs are just binary files with spectral power distriubution… we can patch them easily. Easier in Eizo than Benq since GB-LED EDR and WLED PFS match in size while RGB LED EDR used by Benq has different wavelength size.

    In the same way as with Eizo CN you can replace Benq garbage software with proper EDR:

    C:\Program Files (x86)\BENQ\PaletteMaster\Resources\Instruments\04i1Display Pro.bundle
    C:\Program Files (x86)\BENQ\PaletteMaster\Resources\Instruments\04i1Display Pro Plus.bundle

    BUT… there is no existing EDR for Benq backlights exclusing SW240 (WLED PFS). You’ll need to make from scratch using interpolation an ccss2edr… which it seems it is out of scope of your current expertise. Also if someone did a “forged EDR” for each backlight used in PV/SW/SW-C… nobody shared it, while Stuart Pointon shared them for uysers without experience.

    Blame Benq through support.

    (the above just needs to be done ONE time)
    -calibrate ( do you mean calibrate with display  CN7 + calibrite display plus isn’t it??)
    -done

    yes

    I understood that with this kind of file I could use display cal instead of CN7 to get a more accurate calibration(moretarget) and more option like gamut but probably it would me even more triky

    No, you wont be using “displaycal”. You’ll use your i1displaypro/plus if you had one.

    however, I finally managed to reinstall the colormunky with the argyl drivers by uninstalling the originals and finally display cal recognizes it I checked the contrast and it is:

    1168:1 colormunky photo while with tcalibrite colorimeter  is 1215:1

    Now because CN7  gives me a contrast reading of 1459:1 and eizo only considers that as a reliable value it seems to me a scam., that’s because on photography forum where most of people are not colour expert like you people tendo to trust in the reliability of a big brand like EIZO

    Just happens that it seems that you do not understand what i wrote on previous messages regarding low light readings. If device is accurate on white & primaries, then built in probe is fine.

     

    It is not about price… it’s about physics. Think about it, the size of lens for low light readings on each device.

    Sorry vincent but if I understood what you mean built in sensor on my eizo is too small to read  low dark so black value readin is not accurate.

    Exactly

    In my opinion if a data is not correct for physic reason eizo should simply do not put this data in its calibration report.

    Then there will be no way to use built in sensors in any of these displays.

    Also contrast value meaured in report has no impact in display performance, since by default most software creates fake ICC profiles with infinite contrast and fake perfect neutral grey, just a trick to avoid color managed apps misbehaviors, including Apple’s desktop.

    Me and probably most people that are not experienced in those technical question just trust it…You could think I am stupid ad ignorant but I am pretty sure that if a photographer and not a colorist or an engeneer buy a display just trust what he read and if it is false is not a fault f physic but just a misleading advertising.

    If I dispute with  EIZo customer service  that contrast ratio is different from that what they ( and seller)claim they just ask me for calibration report with built it sensor and if inner sensor sai 1450:1 the say its fine even if the (true) value from display cal say 1200:1 in my opinion it is not physic but uncorrect business claim.

    And they are right for the reasons explained above. Before arguing online with Eizo support or any other kind of support try to learn what is an ICC profile and what a color managed apps does with its information, provided by OS when requesting default profile for each screen.

    By default, and even on purpose, if a display is well behaved you what it to be described by a fake infinite contrast fake perfectly neutral ICC profile.
    If display is bad behaved of you want to create a LUT3D for grading you may try more compex 3d mesh ICC profiles but given the current “rounding errors” in color managed apps like Photoshop (exclusing Capture One, LR develop module and ACR)… the simplified profile is advised if display us well behaved (it display maches such idealuzed behavior).
    There are other threads talking about this.

    Thank you again and   sorry if I’ve irritated you or if you think it’s wasting your time or that I don’t follow your advice, i do my best.

    EDIT:

    I found the folder under C:programdata and  rename the file edr  i got from googledrive folder on Liftgammagain

    https://www.liftgammagain.com/forum/index.php?threads/eizo-apac-calibration-and-workflows-support.16640/#post-163870

    of course deleting the old one(i kept that as you suggested in a separate folding as backup)

    Finally  i startt CN7  set on–preference–no compensation   and start a calibration by calibrite colorimeter.

    Attached  result from eizo software

    I also tried to do a verification from display cal and the same colorimeter putting  and  surely I did something wrong because overal  report is no good as CN7 expecially on white point (i woulod say “assumed 6400K” is a wrong software setting   but i do not want be scolded again as)

    You are using the wrong one in DisplayCAL, GBLED data. So WP error si exected by user miscofiguration. ZIP file inlcudes the exact match for forged EDR.

    Plot TRC, “tone response curve” (gamma) stored in ICC profile and you’ll understand why eizo suport is telling you “it does nit matter”, explained in my previous post.

    The built in probe of any display on any manufacturer should:

    -be corrected to specific backlight in display: WP, R, G, B 255 should report accurately.
    -be able to work with vendor software (this hods partially for CG2420 and CG2730 since AFAIK you cannot verify with it bt maybe newer CN versions solved it)
    -be able to track low light till near black

    and it “could” (would like to):
    -work with 3rd party software (it does: calman lightillusion) through an open protocol (it odes not, so we cannot use it with ArgyllCMS)

     

    the file EDS I used should be for CG319X so according with what I read the most similar to  2700X 2700S

    They are more or less the same. Plot them:
    -CS2731 (1nm)
    -HP Z24x G2 (1nm)
    -CG319x (1nm)
    and even compared to community 3nm files (colorimetercorrections.displaycal.net/), although as you will see if you plot them, using 3nm resolution “blurs” the very narrow peaks in Spectral power distrubution (SPD). Stuart device was able to capture a even twin double narrow peak (3 big peaks) while other devices just see 2 peaks.
    i1d3 devide should notice little change between them, maybe in blue led main wavelength placement.

    Nice. If you enable “additional statistic” check box youll see grey range and other things.

    DisplayCAL report values are by default translated to PCS, working “lingua franca” for color managd apps. Just in case you try to compare CIE xyY/XYZ values in report table to other software.
