I have 203nits and 100nits patchlist for HDR Color calibration which one is closer to 50% stimulation

Which one do I use All patterns are 10bit Including DCI-P3 inside Rec.2020 and Rec.2020 What space do I use

It is Supports multiple saturations I will use 50% I think targeting 203 nits is more accurate

But what settings should I use on ColorSpace

I want to calibrate Samsung TV with the new method that allows calibrating its colors from the service menu i know how

But I want to know how in the ColorSpace

When the color space is set to Rec.2020 2.2, Samsung TV does not support disabling HDR processing. Should I use ST.2084 for HDR Color calibration instead

Not actually sure what you are asking, as the nits vale is separate to the colour stimulus you are talking about.
I think you need another Samsung user to talk to.
But, can you post the information regarding the 'new' calibration workflow, as that may help in understanding what you are actually asking.

Steve, I believe he's just talking about the list of service menu adjustments that has recently been made available on AVS. It isn't a new method or workflow per se.
He needs to use Rec2020 (not with gamma 2.2, as that isn't applicable in Samsung's case), and ST2084.

Thank you Rolls Royce

I forgot to use St.2084 with Rec.2020

True, this seems like the correct way, but I'm not sure because I have an LG TV and color adjustments in HDR are not recommended, so it will be a new experience. I would like to confirm with Steve if this is what I should use to calibrate colors in HDR on Samsung

True, I mean the method in Avsforum is not new and is present in the service menu, but it can be said that it is a new exploration where Avsforum users worked to discover a way to calibrate the colors of Samsung TVs with HDR

Previously they were Samsung LCD TVs so there was not much scope to deal with it with calibration

I'm going to go calibrate my Client Samsung OLED TV tomorrow so I'm keen to give him the best I can, so I asked you about color HDR calibration in samsung

For Samsung only I have LCD QLED TV Of them

Steve

I would put the Samsung TV calibration info here but it's a long thread on Avsforum, and there are floating directions to get to the color adjustment menu using the icons on the remote, but the rest of the info is in the thread After a number of pages from users

I mean the first page has the basics for accessing the color calibration settings on Samsung TVs from the service menu but the rest of the information is in the comments a few pages later in the series

I would like to share it with you and this is the link

Regarding the question about stimulus being separate from nits

I think that i read in general there are specific general standards for calibrating HDR colors from SMPTE,based on which the stimulus was placed

I heard that 203nits patterns equal 58% stimulation

I ask about the stimulation because I read that Samsung relies for HDR calibration in 50% stimulation and 50% saturation in its tv calibration

I found the same information on the light illusion website

(However, subsequent evaluation of PQ based HDR imagery showed a better relative image was attained with a diffuse white around 200 nits. This has since been adopted by the ITU's BT.2408 specification (actually 203 nits), which is 58% of the full PQ signal (input) level)

But honestly I don't really think what I understood from 58% means stimulation

I just thought I read about Samsung that they rely on 50% stimulation

SDR Patchlist have the stimulation level and saturation written on them, but HDR only has saturation in side it

The link for the patch lists suggests using ST.2084 with the REC.2020 color space.

You can modify it by entering your TV's calibrated peak white brightness and then creating a new custom color space based on ST.2084 with REC.2020.

There isn't a P3 color space in HDR10; everything functions within REC2020 under HDR10, so we use REC.2020 with perceptual quantization (PQ).

The patchlists include P3D65 inside REC.2020 to see the P3D65 tracking, but when you calibrate, you aim for 50% of REC.2020 with 100 nits (the most common method).

I own (and have calibrated) a Samsung 77S90. ST2084 with Rec. 2020 is what you want.
