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? |

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(?)

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? Last edited by Damien147; 14th March 2019 at 20:46. |

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?

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? Last edited by Damien147; 15th March 2019 at 16:44. |

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.

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. |

You can find it here: https://cameramanben.github.io/LUTCa...alc/index.html Alternatively, if you have Davinci Resolve installed, you can use it to create new LUTs that best suit your needs. |
