The 528 pattern you sent me triggers the "second set" adjustment points, although 528 is a point in the first set. So I used the closest point in the second set which is 525 to test. Yes the RGB responded to my adjustment.

I was playing with the HDR patterns this morning. I noticed I can CAST the patterns from my PC, and the TV does go into HDR mode and displays the patterns. Are images cast from a PC suitable for basic calibration or should I move the files to a USB drive?
Thanks

What about other calibration and test patterns, especially with different metadata (1000/400, 4000/1000, No MaxCLL/MaxFALL)? Do they trigger first set or second one?

Also I agree with Ryan that it is possible that full range flag could trigger different set of codes. To check this here is an experimental build of C8 patterns with x265 full range flag and codes rounded to 8 bit : link
And limited range as in previous versions but with 8 rounding: link

Out of curiosity, once you've changed WB controls for first set does anything change for the second (2 point WB or 20pt stay the same)?

If you mean playing patterns over network (DLNA?) then I believe that there shouldn't be any difference with playing them from USB.

Hi MV.

I saw that a new set of templates was generated for LG UK65XX. Full Range and Legal Range.
I understand that you have converted Full Range to Legal Range and should use these templates with HCFR. Right?

The table below shows the TV FR values and the correponding LR and Luminance using your worksheet,. To calibrate the White Balance two points, what values should I use? Should I use the standard 30% and 70% SDR?

If they match TV controls and are reacting to WB adjustments then yes, converted version should be used. But I wonder if they do, can you please check if 'full' or 'legal' version matches TV controls?

I've verified video patterns from LG LED UK65xx steps\01. Full range' directory and they do match these calculations. However, all LG patterns should be rebuilt with rounded to 8 bit RGB triples to match software expectations. I'll prepare such patterns this week.

You can measure several patches (e.g. 10% steps) to see how they are reacting to 2pt WB adjustments.

Both worked for me. The FR had better answers mainly in low code patterns

I used the FR code 644 for high and the 395 for low. I got a very uniform calibration. I only modified the codes near black (213, 273, 334 and 365).

Thanks

'Lucky Goldstar (LG)' HDR10 calibration patterns release!

Download link (same as always): HDR10 calibration patterns (Calman & ChromaPure & HCFR)

Release notes:
- All 10bit LG pattern codes (2016, 2017, 2018) are now rounded to 8 bits to match calibration software expectations. (10bit LG code/4 -> nearest 8 bit value)
- LG B8 (OLED55B8SLB) calibration codes. Thanks to YujiTFD from ixbt forum!
- Additional 255 grayscale steps (8bit values)
- Full range LG patterns during conversion to legal range are also rounded to nearest integers: ((10bit FR code)/1023)*876+64=(10bit LR code)/4=8bit LR code
E.g. Full Range10 bit LG code 385 -> Legal Range 8 bit code 99
(385/1023)*876 + 64 = 393,677 -> 394/4 = 98.5 -> 99

Thanks to everyone who is publishing calibration codes!
Any additional codes are welcome and would be used to build free HDR10 calibration patterns!

Does anyone have a premade usercolors.csv for HCFR + C8 + HDMI to use with these patterns? I've tried to create my own but I'm not sure I'm entering the triplet values correctly.

Thanks.

Q9FN Settings

Came across this a few days ago while desperately trying to calibrate my Samsung Q9FN. Thank you so much for this - has proved invaluable especially since I can't get professional calibration in HK.

Used the HDR patterns to good effect : https://www.avsforum.com/forum/166-l...l#post57624176

A couple of queries if I may please :
1) Contrast : (was 43) 41 : I had it originally set an average to track the EOTF curve better - average setting for 1000 (40) & 4000 (45) nits (Rtings dot com). However on the HDR10 White & Colour Clipping tests, White was maxing out at 1500 and Colours at 1400 on a 10% window. From various measurents, this set is easily capable of 1700+ nits on a 10% white window so I backed off until 1700 bar was flashing. Is this valid thing to do?

2) My red level is clipping some 300 nits less than all the other colours in HDR (1600 nits) & SDR. Is this an indication of maybe something wrong with my panel?

Thanks!

Hi All. Forgive me, but I can't seem to download the HDR test patterns - it's just downloading an explorer link that just prompts another download of the same link? Any tips pls?

Hi, any tips on how to save and unzip the HDR10 files? As above I'm downloading the smaller HDR10 test pattern from google doc link, but it is just saving a 99mb internet explorer link, which when opened prompts another download of the same link :/ am I doing anything blindingly obvious wrong? thanks

I just tried it and it downloaded the 2.1GB 7z file properly. I was using Google Chrome.

Thanks for replying. I'm not quite sure what's wrong then. I've tried that file and the one with Calman files in too.
The first one you did, I downloaded with Chrome, and the file is over 2million KB, so it appears it's downloaded the 2.1gb file, but the thumbnail is an internet explorer icon, when clicked prompts the download of the same file again. There are no unzip options for the file/link either.

Sorry all.

I think I've got it. I didn't have a proper unzip program installed. It appears to be unzipping the files now.

Out of curiosity, is there a set that is more suited for the average man that is doing it by eye?

Thanks again.

It should be a 7z file. Windows doesn’t have any built-in app to unzip it; you need to download the 7-zip app or something else that can open it.

In HCFR open 'Preferences' -> References tab -> Color Checker patterns. Then choose LG codes (2016/2017) or select 'User defined' and edit codes sequence in usercolors.csv file in HCFR install directory.

I believe that FZ800 WB calibration codes could differ from LG. If so, you can manually gather required grayscale patterns sequence manually with 255 grayscale steps (in Misc directory). Or you can post codes and I' add them to the set.

I think that some HDR color clipping is expected for current TV and could be called normal unless you're getting very low clipping levels and it's highly visible in real contet.
Also I believe that it's not a good idea to change TV Contrast settings judging only by clipping levels. You'll need a calibration sensor to measure EOTF tracking and see how it reacts to Contrast changing.
Furthermore, rtings measurements from Q9FN are different for 1000/4000 HDR10 metadata. You can find additional clipping patterns with different metadata variants in 'Fake Metadata' directory and check how your TV reacts to them.

They should be white or gray. You can also check out grayscale ramps/gradients and grayscale steps (in the 03.Grayscale directory)

Thanks. I had originally used an average contrast (43) of the Rtings measurements for 1000 & 4000 nits but took it down to 41 so i could see white bars at 1700 nits on 10% window

Agreed its not the best idea to do it by eye but that;s the only option I have currently while waiting for Calman Home package. I could go for x-rite meter and other software but the Calman AutoCal feature is very appealing for a newbie.

I have the same but setting Red Gain to -14 in 2 point white balance resolved. Has probably messed up everything else as per my post in Q9FN owners thread

ok, but in usercolors.csv, there already is a lot of values in. I can delete them all and only add the LG display 2018 values ?

So if you're planning on adjusting 20pt WB controls on LG OLED then LG-specific patterns are required.
But if you're planning doing 2 points WB adjustment you can use use 'generic' grayscale patterns with 5-10% steps. However, as far as I know, 2pt WB controls are blocked in HDR mode on 2016 models and only 20pt WB is available.

Thanks for the patterns.

To adjust 12pt WB on a Panasonic OLED FZ950/952 should I use the generic grayscale patterns?

It depends on white balance codes FZ950/952 is using for HDR10 calibration and if they coincide with 'generic' 5/10% steps.
In case if codes don't align with 10% or 5% steps or additional patterns are required, e.g. 2.5% or some other, you can find find them in 'Misc/Grayscale 255 steps' directory.

My best guess is that codes should be displayed in WB menu while TV is in HDR10 mode.

What are the correct "Master Max L" and "Master Min L" to use in HCFR?


When using the 1000 MaxCLL files, I put Master Max L at 1000, and when using 4000 MaxCLL ones I use 4000. Is that correct?
No idea what I'd choose for any of the parameters if I use the No MaxCLL files.

I've been keeping the Master Min L at 0 for all.



I appreciate any guidance.

Thank you very much for the effort on the patterns, great work!. They're extremely helpful to perform accurate adjustments to TVs/Displays.

I've been chasing an anomaly that I'm seeing with the clipping patterns, and I was wondering if you or others could help me out.

I'm referring to your clipping patterns here:
https://drive.google.com/drive/folde...EkViQlr0wvpWhG

-and we could use the "03. 900-4000nits.mp4" pattern for the discussion, though the issue is applicable with all files mastered at >1000 nits.

On my PC setup comprising of:
Windows 10 x64 on the latest patches
MPC-HC v1.84
MadVR v0.92.17 or madVRhdrMeasure78, set to pass-through to display
LAV filters 0.73.1 or 0.74
NVIDIA GTX 1060 6GB, vdrivers 385.25 through v419.xx
Operating at either RGB 8-bit Full 0-255, or YCBCR 12bit Limited 16-235
LG C8 TV, on the Cinema HDR profile in all modes (dynamic tone mapping ON by default)

Here's the issue:

If I play the "03. 900-4000nits.mp4" pattern on my PC, I see is that the peak white and all colors tone map very well, but only up to 1000 nits, and everything is clipped beyond that, as you can see from the images below

My worry is that HDR movies mastered at >1000 nits (and I have many) that I'm playing from my PC aren't being tone mapped and displayed correctly as per the creator's intent.

But, if I play the "03. 900-4000nits.mp4" via a USB drive connected directly to the TV, I see that peak white and all colors tone map very well almost up to 4000 nits, as you can see from the image below.

But the internal TV player can't pass through lossless audio via it's audio return (since the TV doesn't support eARC) which is why playing from the PC (HDR+lossless audio is possible) and getting the TV to tone map to 4000 nits becomes very important.

Madshi (the creator of madVR and I had a discussion about this as I initially thought it was a madVR problem, but now I'm not so sure.
The discussion can be viewed here: http://bugs.madshi.net/view.php?id=605

One thing we observed were the properties set in the file, namely:
Mastering Display Peak: 1000 nits
MaxCLL: 4000 nits
MaxFALL: 1600 nits

When I enable debug OSD on madVR while playing "03. 900-4000nits.mp4", I see "HDR 1000 nits" being reported (can be seen in the 2nd image attached to this post) , in which case, if this is what's being sent further upstream to the GPU driver/LG panel, it might explain why we don't see the TV tone map beyond 1000 nits when played via the PC. According to madshi the 'HDR 1000 nits' comes from what LAV filters read from the file, and LAV filters is passing that onto madVR.

If so, this might also might explain why the TV is able to tone map the same file to 4000 nits when played via the TV directly, as the TV uses it's own proprietary media player, which might be parsing the file and utilizing "MaxCLL: 4000 nits" as a reference instead of "Mastering Display Peak: 1000 nits"

Could you please review and let us know what you think the problem could be? I'm happy to try out the same file encoded with a property of "Mastering Display Peak: 4000 nits" instead of 1000 nits, if that's possible for you to encode and share, and we could see what happens. But this could very well not be the cause, and might be something else in PC->Mediaplayer->decoder->GPU->TV chain causing the issue.

Request others to chime into the discussion as well if you have any ideas.
Thanks, and appreciate your help folks!
