Actually, I'm taking it one step further. I am redesigning the entire LG OLED pattern set. This go-round I will be utilizing 8-bit shifted to 10-bit values vs the original true 10-bit implementation, as this will align better with current calibration software and was confirmed by LG as a valid method. I was also provided updated metadata that will be implemented within the new pattern set as well. The pattern resigned will incorporate new verbiage that will state, sequence, bit values, percentage and the original Full Range values request by the display's UI for reference. Also, the on-screen text was reduced to a point that will not skew APL during measurements and will be able to stay on-screen for the duration as a reference. Here is a list of what is being updated:

- 2016 (540 nit)

- 2017 (540 nit, 1,000 nit & 4,000 nit)

- 2018 ( 1,000 nit for all 3 pattern sets) + The LG UK65xx series at 1,000 nit

- 2019 (1,000 nit & 4,000 nit)

I should have this completed by early next week and will be available shortly thereafter. I will most likely provide this as a re-release of REV_025. Thanks!

Some good news the Samsung Q9FN (2018), DVS HDR10 patterns and Calman (version 5.9.2.59) autocal HDR workflow does work - well sort of.

The Pre-calibration step works fine, of course.

The 2 point white balance autocal step works fine with the manual patch prompts.

The luminance step works fine.

The greyscale starts OK, but then there is a problem - missing patches!

The following grey patches are used by the Calman Samsung QLED HDR workflow and are missing from (or at least I cannot find them) the DVS HDR10 patch set, including the Samsung 2018 patch set in the miscellaneous folder:

34.7%
40.6%
61.6%
67.0%
71.0%
73.5%
74.4%
75.3%
76.0%
76.7%
77.0%
78.0%
78.5%

All other patches used in this step can be located.

I've attached a screenshot of the 20 point Greyscale screen from Calman.

@mascior , are you able to create these missing patches for the Samsung 2018 HDR Calman workflow please?

Yes. I can add these to the set. I will have a copy of them in the Samsung file folder and within all of the workflow file folders as well. I'll have them available next week with the rest of the additions. Thanks!

I just got finished speaking with one of the Senior Directors of Engineering over at LG, who assisted with the implementation of the 20 point WB code specific values. He just confirmed my theory, both Full Range and/or Limited range triplet values may be utilized. If the Full Range values are to be used, then the patterns must be encoded in Full Range, not Limited Range. However, if the Limited Range values are to be utilized, you must perform a conversion from Full Range to Limited Range on all of the triplet values. Please keep in mind, when utilizing the Limited Range patterns, you will be using different triplet values vs what is being requested by the display within the UI. So even though the values do not match, the percentage values will still align. It was also mentioned that dynamic contrast must be disabled prior to calibration, as this will skew results.

With that being said, all of my 2016 and 2017 patterns are correct and I have deleted the Full Range section from the pattern suite entirely. I will still have to address the 2018 patterns, as all three sets will need to be converted from Full Range to Limited Range and encoded. These will be available within the next revision. If anyone has any further questions or concerns regarding this matter, please feel free to reach out. Thanks!

- Ryan M.
Amazing work Ryan! Thank you!

Just to be clear. Once we have the new patterns from you, as long as the percentage value matches we are good?

Hi Ryan, how can we tell when the new patterns are available for download? I don't want to use up my download limit unnecessarily - already lost a couple thanks to my AV system getting over enthusiastic ;-)

Thanks. Only purchased a couple of weeks ago, so it's good to understand how the update process works.

Diversified Video Solutions UltraHD|HDR-10 Test Pattern Suite (.mp4/.ts) update REV_025 Re-released!

**NOTE: This revision was compresses with 7-Zip. To extract, please utilize the 7-Zip extracting utility found at http://www.7-zip.org/ (Windows) or The Keka extracting utility found at http://www.kekaosx.com/ (iOS)

Description

This re-release encompasses a few updates, additions and/or modifications to the existing test pattern suite. One of the main modifications are the LG Display code specific test patches which have now been updated to align with all 2016, 2017, 2018 & 2019 OLED Models, along with the UK65xx series LED-LCD’s. Secondly, we have added a secondary code value grayscale sweep to the 2018 Samsung series of LED-LCD’s. Please see the detailed description below. Thank you!


New and Modified Pattern Description

Miscellaneous Setup Patterns

- The LG OLED code specific test patch file folder has been renamed to “LG Display Test Patterns” and now includes two sub-folder, OLED and LED-LCD.
The 2016, 2017 & 2018 patterns have been re-designed and now utilize 8-bit shifted to 10-bit values vs the original true 10-bit implementation. This will align better with current calibration software and was confirmed by LG as a valid method. The new patterns also incorporate new verbiage that will state, sequence, bit values, percentage and the original Full Range values request by the display's UI for reference. Also, the on-screen text was reduced to a point that will not skew APL during measurements and will be able to stay on-screen for the duration as a reference.
A new 2019 code value set was also added and is available in both 10 step and 22 step configurations.
New 2018 UK65xx series LED-LCD code values were added as well and can be found within the new “LG Display Test Patterns” file folder.
Also, all the above patterns have been added to the available workflows under the grayscale file folder and as always, includes a combined stream for ease of use.

- 2018 Samsung code specific test patches now include a secondary code value set that align with newer firmware and models.


Pattern Suite File Size

10.1 GB (10,894,125,521 bytes) Zipped/Compressed
30.0 GB (32,301,358,642 bytes) Unzipped/Uncompressed

(All customer download limits will be reset and new links will be distributed)

Hi Ryan,

Thanks for updating the Samsung 2018 greyscale patterns.

I've just tried running through an Calman autocal run with the new 20 point Samsung patches (set 2) I noticed that the 71% and 76% patches do not match the Calman patch values in 8 bit RGB as below:

Patch, Calman 8 bit, DVS 8 bit, DVS filename

71%, 171, 172, 09. Samsung 71.0%_C172_HDR10
76%, 182, 183, 15. Samsung 76.0%_C183_HDR10

I also notice that the 76.3% patch filename also suggests an 183 8 bit value, 16. Samsung 76.3%_C183_HDR10

Can you recheck the 71% and 76% patches please?

Jay.

Hi Jay,

The patterns in question are correct. I just re-checked the math. I will reach out to Tyler and see if this can't be correct within their software. Thanks!

71.0% - 686/4 = 171.5 (apply round nearest) = 172

76.0% - 730/4 = 182.5 (apply round nearest) = 183

76.3% - 732/4 = 183

** As for the dual 183 triplet values, there isn't much that can be done, as everything is broken down to 8-bit.

Hi Ryan,

I thought it may be a rounding/trunking issue causing the differences; thanks for checking for me.

I've also taken a look at the calman autocal CMS which is now a three pass "Samsung Multi-CMS" at three different luminance values. I've listed all the calman values below. I'm struggling to track down the right patches, can you advise please?

Hi Jay,

The current DVS CalMAN workflow only incorporates 50% luminance/50% saturation CMS patches and 50% luminance saturation sweeps. I can easily add the above in the next revision. However, for the time being, you can utilize the standard HDR-10 workflow within CalMAN, which follows the pattern sequence found within the DVS CalMAN workflow file folder. Thanks!

Hi Ryan,

Thanks for the advice. Sorry, I seem to be giving you lots of work to do. I look forward to the next revision.

Dolby Vision is my primary focus at the moment. However, it is taking a lot longer than anticipated. This project has been the most challenging from every aspect in comparison to the others, with the main challenge, dealing with Dolby's proprietary mapping within their workflow, followed up by multi-step encoding and extremely long transcode times. Also, I had to re-evaluate how I was going to implement this product, as most post production Dolby content targets multiple displays at different nit levels and color spaces within one file. I am still aiming for the end of the first quarter, possibly early into the second. I would like to thank everyone for their patience as I finalize the first revision of this product!

Does this need a meter?

Interested in this for my Q9FN but is it like the AVS HD calibration where it can be done by eye or does it need a meter?

Some of the patterns look v similar to AVS HD so should be able to use those by eye right?

Thanks

By eye calibration has been proven to be invalid for accuracy(Other than Contrast & Brightness). It is a complete waste of time and money spent on resources. I highly recommend you do some research. If you still want to improve picture quality, then buying the necessary tools learning a new skill or hiring a professional are the only valid paths.

By eye, to make it look the way you like.

Accuracy, not even close!

Yes. It can't be called "calibration" if you don't use a meter to take measurements, by definition

If it helps, imagine putting up a set of shelves "by eye" without using a spirit level.

Technically contrast and brightness are considered calibrated by eye.

There used to be lots of guys who calibrated by eye! It saved money on equipment, software and training and everyone always raved how great the results were. AND you could always share and use the same settings on everyone's set even across TV brands .

By eye means to make it look like the sets down where the TV was bought! (And we know how accurate they are! That's what got you to buy the set in the first place.)
