    Right, so after my pervious message I did some more fiddling around and I think I might have found a solution to the original gray balance problem.

    I went back to using ColorNavigator7 and calibrated using the built-in probe (for some reason CN won’t recognize my i1DisplayPro) and the following settings:

    – Gamut: Native

    – Gamma: 2.2

    – Brightness: 100cm/d2

    – Priority: Standard (tried Gray Balance but got better results using ‘standard’)

    – Black level: Minimum

    – White point: 6500K

    I then went into DisplayCal and started my normal Resolve calibration setup but when it opened with interactive white point adjustment, rather than just clicking through to profile I opened ColorNavigator again.

    In CN7 I clicked on the profile I’d previously created and clicked Manual adjustment.  In this menu I was able to adjust the RGB balance while keeping an eye on the DisplayCal interactive display adjustment window so that I got all the bars to line up.

    You then need to save this as a new profile in CN7 and let it do a quick calibration but after that everything should line up with DC’s bars.

    I then quit the DisplayCal calibration I had open and started a new one using the settings already discussed above but using ‘As measured’ for all the settings in the calibration tab and relative colorimetric rendering intent in the 3D LUT tab.

    I checked that the bars still lined up in the interactive display adjustment menu and then went through to calibration.

    With all that followed I get the following measurement report.  While combined RGB gray balance range isn’t perfect (1.1) it’s much better than it was before and this is with a white point reading of 0.26.

    The only thing that I want to check is whether or not I have my 3D LUT’s tone curve settings right.

    – Custom

    – Gamma: 2.2 (absolute)

    – Black output offset: 100%

    Is there anyone that anyone can see here that looks off or have I finally managed to get a decent calibration?

    Thanks!

    Better approach than mine for making CN apply the same white. All but grey 26 seems on spot. IDNK its cause, check if it exists without Resolve LU3TD

    So is it safe to say this is a pretty good calibration then?

    Post: 23505

    What I’ve ended up with is an even worse profile than before which doesn’t make sense to me.  The RGB gray balance combined range is 2.67 which is obviously not great.

    I assumed that doing everything through DisplayCal would take a lot of the complication out of things.  I’ve attached the measurement report.  If anyone has any insight as to why my RGB gray balance is so bad that would be amazing.

    Also out of interest can you think of any reason why when I bypassed CN before and just did everything in DisplayCAL I got a bad result?
    Just so I know for calibrating other monitors which don’t have the option of CN7.

    Hello Macleod!

    Thanks for this as I am looking to get the CG2420 and am a bit confused (of course). I decided to move from Premiere to Resolve after taking a color grading course online. What I didn’t realize was that I needed more hardware to make it work properly !

    Since I have already paid $300 for the Studio version of Resolve, I guess I have to go with it.

    I’m on Windows 10 and deliver at 1080p. I’m planning to purchase: Eizo CG2420, Blackmagic Mini Monitor, and the Xrite i1 Display Pro.

    A few questions about that:

    1) After using the CG2420 for awhile do you still recommend it?

    2) Sincw the CG2420 is not a 4K monitor, why would someone get the Mini Monitor 4K?

    3) Xrite also makes a “pro plus” model. Do I need that for the CG2420?

    4) Is there anything else I need to buy or you suggest buying?

    Additionally, I’m assuming I can refer to your original post and figure out how to calibrate the monitor for Resolve. Although, it appears that some of your updated posts suggest you discovered some alterations to your original instructions.

    Can you possibly repost your original instructions with the updated discoveries included?

    Also, as someone who has never done this level of calibration (I have only done icc profile calibrations on an older Dell U2410), will I be able to refer to your “definitive guide” instructions and figure this out? If not, can you point me towards any other required reading.

    Sorry to ask so much and I greatly appreciate any help!

    Hi Malcolm – sorry for the delay in getting back to you.  I hope I can still be useful.

    1) After using the CG2420 for awhile do you still recommend it?

     

    I definitely do think it’s a good monitor.   Honestly my headache is still calibrating and being confident in the results but so many other people also like the monitor so I’d have to side with them

    2) Sincw the CG2420 is not a 4K monitor, why would someone get the Mini Monitor 4K?

     

    This was purely for future proofing, no other reason.

    3) Xrite also makes a “pro plus” model. Do I need that for the CG2420?

     

    My understanding when I looked into it was that the pro plus was only really useful if you were calibrating an HDR monitor which the CG2420 isn’t.

    4) Is there anything else I need to buy or you suggest buying?

     

    If you’ve got a calibration probe and something like a Decklink so you can bypass the GPU then I can’t see what else you’d need to buy.

    I would like to make it very clear that I’m by no means an expert on this topic so please do let others guide you!

    Also – I’ve put together the step by step guide based on this thread to make it easier to follow and update in the future.  As I said above, I’m not an expert and really have been guided by the advice from people like Vincent.

    As you’ll be able to see from the results that I’ve included in the guide my calibration looks fairly decent, with the exception of the dark end of the spectrum which does seem to drift a bit.  I’ve also done a profile using LightSpace CMS just to get another verification of the results.

    If anyone can think of any way to improve the grays of this calibration or has any suggestions in general then I’d love to hear them (I’ll do my best to keep the doc updated in the future so it’s easier for others).

    Wow Macleod, thanks so much for these thorough and thought out responses. I wish you and yours the best in these times.

    Stay creative !
    Peace
