    edit: oops,I misread your post.
    I created a 3D LUT with default settings because I want bt.1886.For HDR I have to create one more SDR 3D LUT with tone curve in displaycal's 3D lut tab set to gamma 2.2.Right?
    If yes then I go in madvr's calibration tab and put it in DCI-P3?

    if you want a to use an SDR LUT for HDR you should create it with gamma 2.2.

    if the source is DCI p3 then yes you put it in DCI p3.

    Oh,then I need Bt.2020.I am like that now with default displaycal settings and I need to add one SDR 3d lut with bt.2020,gamma 2.2 in madvr's calibration tab to conclude without changing anything else(?)

    if you are using a HDR->SDR 3D LUT(and your screen clearly says you are) the SDR 3D LUT isn't used for HDR so you don't need a gamma 2.2 LUT and you don't "need" BT 2020 sdr 3D LUT.

    That's convenient.Was wondering that actually for the OSD(showing only one).Then I leave things as they are and I am ok.Thank you one more time for being helpful.

    Can anyone guide me how to adjust CMS using HCFR?
    I mean when adjusting 2 point you put a test pattern and adjust offset,gain to match 100% rgb in HCFR.For CMS you put 75% test pattern and do what?

    Be careful adjusting the display's CMS, they often do a very bad job. Make sure to run saturation sweeps of the primary and secondary colors before and after. You do not want curves in your saturation sweeps. I have never gotten good results from a display's CMS when adjusting primary or secondary colors.

    The adjustment is similar to white point, adjust saturation, tint, and luminance to get the dE as low as possible. If you change them while watching HCFR you can see how each option moves the color.

    In TV's CMS I have r g b to adjust(samsung).I don't get the similar to white point.For example I've put the 75% red pattern and red is way off to reaching 100% if I remember well.
    As I said in 2 point you adjust to match 100% rgb in HCFR,what do you do similarly for CMS?

    Messing with the primaries is very unlikely to help anything, you can only lower the brightness or add the other colors.

    In two point you don't adjust to 100% rgb for high and low. You adjust to 100% white and something like 30% white, don't you? If you use a 75% red pattern you need to match it to 75% red, did I misunderstood you?

    I've seen online that they adjust CMS when calibrating my TV and thought that I have to do it myself too.Do you suggest to leave it at auto?

    Sorry,let me say it again.Yes,in 2 point you adjust to 100% white(if you have 10 point,if not 80%) and something like 30% gray.You open the 100% test pattern and adjust TV's RGB gain to match 100% of each r g b in HCFR.Then you open a 30% and do the same with offset.
    To adjust primaries and secondaries I've read that you use 75% color.I open a 75% red pattern and then do what with CMS's RGB and HCFR?What am I looking for?

    What options do you have when adjusting a primary color? I am not familiar with Sony's CMS and am not sure what you should do if you don't have saturation, tint, and luminance adjustments.

    In HCFR you compare your 75% red to a 75% red and are looking for a low dE. Often luminance is the value that is most off. It is important to configure HCFR to use the real max brightness at 100% white as its reference when doing this.

    It's like this.Ok,I am looking for low dE but what do I do to achieve it?

    Fiddle with R, G, and/or B.

    Sorry but that really is it. Increasing G or B will reduce saturation and raise luminance, decreasing R will lower luminance and may or may not change other aspects. You do not have a lot of control when messing with the primaries so if you cannot get it any better after fiddling then I would conclude that it is as good as possible. I would probably leave G and B on 0 and R at 50 and use a 3DLUT to do gamut correction for madVR, unless I could get it very good and it did not mess up the saturation and grey scale sweeps. Using the TV's CMS to get the primaries or secondaries slightly more accurate often has a trade off that isn't worth it.

    You will need to adjust the white point again if you do adjust the primaries.

    I googled and read various guides but no one explains it like grayscale for example.
    What matters to me is PC mode and there everything went fine.Some options are missing but what I need is there.
    About the primaries and secondaries that I asked now is for another mode that is for plain TV watching.So no 3dlut option for me.I don't truly care but why not calibrate it when you can?
    I guess by your sayings it's no biggie but it would be nice if anyone knows and answers.Thanks.

    there is no general answer to that it really depends on your device.

    You are right.I give up and if it happens and someone knows good.If not I am leaving it at auto and all good again,it's just for regular TV.Thanks guys.
