Doesn't it need to be though?

If I'm showing a 5% grayscale pattern, and doing a 20pt cal on an E6P, the E6P doesn't have options for 5%, 10%, etc. It's got codes. If the first code is 0%, but the second one is 7.67% (just as a for instance), am I supposed to use the 5% pattern and make adjustments to that 7.67% control based on the readings that I'm getting from HCFR reading the 5% pattern? Or am I supposed to use the 10% pattern to make adjustments? Or will none of them be right, because I'm getting readings for a pattern that the TV doesn't have a control to adjust?

That's what I'm not sure of.

Generally you should output and measure exactly the same patterns your software is expecting. So if in HCFR you'll select 5% then you should output 5% pattern. But for grayscale calibration of LG OLED you'll have to select (or setup manually) specific grayscale workflow with LG specific codes in software.

That's what I thought.

Zoyd has said that he will add the LG OLED coded workflows to HCFR, perhaps in the next update.

Spanish release of HDR-10 Calibration Patterns!

Donwload link: HDR10 calibration patterns (Calman & HCFR)

Updates:
- LG OLED 2018 grayscale calibration patterns, LG OLED 2017 with MaxCLL 4000
- additional version of combined patterns: 3, 5 seconds and 'hybrid' delay - 10 seconds for patterns below 20% and 3 seconds for rest. Thanks to @jwhn for idea!
- new archive with two extra MaxCLL/MaxFALL patterns variants: 1000/400 (existing patterns), 4000/1000 and no MaxCLL/MaxFALL (! Unpacked archive size >14Gb.)

I have Samsung chg70 monitor. Display has 600nits brightness. I tried black level test and color clipping test. Windows hdr mode is suck with madvr. Cant show below 80 black levels and clipping above 650 nits. AMD Vega results are perfect for both black levels and color clipping for the 1000 nits content. It cant show above 1000 nits.

Converting HDR content to SDR with external 3DLUT is nice. Pixel shader math bad.

Processing HDR content with pixel shader math can help subpar windows hdr mode (OS HDR on the madvr)

I didnt tried HDR 3DLUT yet. Its hard to create one.

Thanks for this awesome work.

HTPC 4:4:4 [4K HDR] chroma test: download link

! Disclaimer !
Test uses non-standard HEVC encoding with full chroma 4:4:4. Hardware decoders don't support it so most certainly video players won't play this test.
HTPC can play it using software codec (e.g. avcodec).

Depending on chroma subsampling used by HTPC/TV red/blue font and stripes in central left column will be very clear and sharp (444) or blurry (422, 420). Central right column contains 300% magnified examples.

You can find few fullscreen patterns here:

Or if it's not what you're looking I can easily generate whole bunch of fullscreen slides.

I noticed an error in one of the patterns. HDR10 Grayscale, 5% steps, 85% should be 808 and it says 880. Is is encoded correctly at 808?

Obviously on most current sets it won't make much of a difference, I'm just checking to make sure.

Living Room: Sony XBR65X930D, Sony HTCT780, Base PS4, Philips BDP7501

Yes, it's a typo in text label and file name, actual RGB code is 808 in 10 bits (corresponding 8 bit code 202).
I'll fix the label it in next build. Thanks!

I tried this pattern on my tv, and it looks like this

Red seems to be the most saturated, it does not blink, unlike yellow for example, you can see the same rectangles as white.
Note: The blue blinks all from 240 to 1000 but in the photograph can not be appreciated, and my TV is calibrated correctly and has the maximum backlight, HDR10 is ON and Color Space is BT.2020, the other values ​​are exactly the same as those I use in SDR.


Is it normal for the pattern to look like this? Or all the colors have to flash at the same level.

I'm confused about this, I hope someone can help me understand what is happening

Hi Oliver,
Color clipping levels could differ and I guess that it could be called normal for current TV's, none of which are capable of displaying full HDR10 color volume or luminosity levels.

Forgive the question but how do you know those are the values that your C8 "has"?

Hmm. Good question. Those are the values I can enter under the 20 point white balance in HDR mode. You're saying the values shouldn't match the files provided?

No, I'm saying how did you decide which values to enter under the 20 point white balance in HDR mode?

Well, I used a meter on the supplied patches and matched them as best as possible with the values available. It was a few months ago (when I first got the TV) and I now wanted to check if anything had changed and improve my knowledge, hence the post above.

I feel I have SDR calibration down pat but I'm fairly new to HDR calibration, so if I'm doing something obviously wrong then please let me know. I'm still unsure why the calibration patterns don't match the code values offered in my C8.

Lg led 2018

I have a LG Led 2018 (not OLED) and the 20 pts codes for the HDR calibration are as follows:

53,53,53,213, UK65xx Serie 20 Point GrayScale 68,68,68,273,
83,83,83,334,
91,91,91,365,
98,98,98,395,
102,102,102,410,
106,106,106,424,
109,109,109,439,
113,113,113,454,
117,117,117,469,
121,121,121,484,
124,124,124,499,
128,128,128,513,
132,132,132,529,
136,136,136,545,
141,141,141,565,
146,146,146,587,
153,153,153,613,
161,161,161,644,
255,255,255,1023,

I made this table for the HCFR (please check if this is ok), but I can not send the HDR patterns via HMDI through the notebook.

Can anybody help me by generating these patterns to use on USB or Blu-ray?

Thanks

Here is a quick experimental build of grayscale HDR10 patterns with additional patterns for LG LED UK65xx based on 10bit codes provided by @wmfam and additional 2018 OLED codes by @holdemphil (in ver2 directory).

Also fixed typo pointed out by @morphinapg, switched to x265 ver.2.9, added additional text label with Mastering display luminance and 8 bit RGB codes for 5/10% patterns.


Download link.


Be aware that it could be not final version.
Ideally I need exact RGB codes (or xyY targets) expected by calibration software to avoid unnecessary 10bit->8bit rounding errors.


HCFR allows to export targets to xls file. Not sure about RGB triplets.


Calman allows to copy-paste RGB triplets directly from datagrid after some tweaking. Here is an instruction by Ted - link. RGB code checkbox is somewhere below Target_x, _y. BTW Target_x, Target_y and Target_Y also also won't hurt with extended 15 digit decimal precision.

Most convenient way is to copy-paste those values from datagrid to excel document (xls).
It should look somewhat like this:

Initially I've used codes posted in the 2018 LG OLED Calibration thread in april.
If latests C8 firmware has different codes then not only new patterns should be used but also targets in software should be updated.

:

Thanks for the quick generation of patterns. I asked LG about the luminance and RGB values.

I made a comparison of the curves expected by the HCFR and OLED TV 2016. They are very different.

Follow the data obtained after calibration with the LG UKXX patterns.

I also did a reading with the standard HDR patterns and compared the curve with that expected by the HCFR.

The 100% pattern in gray scale steps is 10,000 Nits for all sets (100Nits or 4000Nits or 10K Nits) that is in the OP link.
Shouldn't it be different based on the set?

I also did a reading with the standard HDR patterns and compared the curve with that expected by the HCFR.

Have you switched HCFR to PQ (ST.2084) mode?
Luminance readings seem to be very low: peak white is only 200 nits and middle range is also much darker than expected. E.g. 55% should give ~150 nits but you're getting only 50% which is 92 nits.


BTW
Are codes you've posted in PC or TV range?
