Hey everyone, I have maybe a dumb question.

I created a meter correction profile for my i1 Display Pro against a i1Pro 2 spectro I just picked up. I used HCFR and did a manual calibration in SDR mode on my LG C8, it came out great.

Can I use that same meter correction file I created using SDR patterns to calibrate in HDR as well? Or do I need to create a separate profile using HDR patterns?

Thanks

I'm not an expert but I believe you can use the same. Using a c6 that has meter profiles built in, you don't have to change the profile for an "hdr" calibration

I'm not sure this is correct. From my testing Calman matches Lightspace only when the workflow is set to limited with the RPi at full range, and I'm 99% sure my Lightspace is configured correctly.

Ticky, I’m sorry but I have to correct you pal. RPi is bit accurate in RGB Full (as you correctly said) BUT when calibrating a TV for SDR content, LightSpace/CalMAN videoscale has to be set to 16-235. This is how I tested it. I don’t know if LG OLED TV automatically recognize input signal color space videoscale, on my Kuro I have to manually force the HDMI settings to RGB 16-235.

Is this wording correct?
Raspberry Pi RGB Full + Calman Workflow basic options: Luminance level=Video (16-235), make sure the TV has "Black Level=High" - this will be "bit accurate".
OR
Raspberry Pi RGB Limited + Calman Workflow basic options Luminance level=Video (16-235), make sure the TV has "Black Level=Low" - this will not be "bit accurate".

Is there a flowchart or slide somewhere showing LG's 2018 WOLED image-processing engine?

How incoming 8-bit values are converted for entry into the LUTs, how many bits of precision within LUT entries, used to comoute interpolated output values, and bits of precision on the output values themselves, that sort of thing...

I'm trying to understand how 8-bit RGB or YCbCr inputs get processed from the HDMI input all the way to the TCONs that drive the WOLED panel so if there is any reference document of thread where those details are discussed, I'd appreciate a pointer...

Wait, that "black level" setting is the control for selecting 16-235 vs 0-255 !?!

I always thought that was. . . well, some other setting and the only way to set it to PC (0-255) was to change the HDMI input label to "PC". . . have I been misinformed all this time?

Yes. But it should automatically be set correctly, if the AVI Infoframe and other metadata in the HDMI signal is correctly set to tell the TV whether it's "Low" (limited range) or "high" (full range). The two words Low and High do not sit well with the words "Black level" and are tremendously confusing, since "Low" means black is 16, which is a higher number than "high" where black is 0.

The Input label=PC setting turns on 4:4:4 chroma sub-sampling if you are feeding it YCrCb.
But if you're feeding it RGB, this is equivalent to 4:4:4 but in the RGB space, it should always be "High", so I don't know what happens if you do not set the input label in those cases. Nothing wrong with setting it to PC just to be safe IMHO. But check it's saying "High". If you can't change it or it is greyed, this means you are sending the TV YCrCb and not RGB.

my question is what setting i might wrong to cause 3D LUT so bad but RGB balance in post cal check is looks good in SDR cal.

if you have any suggestion, i am all ears. Thank you so much.

TV: LG OLED 65 B8P
SW: Calman 5.9.2.59 Home Enthusiast
Meter: i1Display pro retail 2011 model. (i bought it aroud 2012, so it should be. 0.1 - 1000 cd/m2)
TPG: Rpi PGenerator with 2.0.16 DeviceControl on Rpi 3B+

Settings:
TPG: 1080p24, RGB Full
TV: Active grayscale points = LG 26 pts 16-235
PG control interface options: Windows size 10%, Pattern APL 25, Pattern size 8
Workflow baisc option: Colorspace target= D65, HD, BT.709; Gamma fomula=Power 2.2; Luminance level=Video (16-235)
Application measurement options: Full Fieid Pattern insertion= Freq 30 (1D LUT), 15 (3D LUT); Duration 5; level 15% ; AutoCal targets DeltaE formula=de2000_jNDab, Cube deltaE formula=de2000
3D LUT: iRP point based LUT = 5000 pts

Post Calibration View is confuse me that is RGB balance looks flat so i assume which is good. Howerer, de2000 color delta error is huge.
Hi, when you want to generate APL with custom size patterns, you need to select user defined and set APL and size.

When you select 10% Windows, it will generate 10% window and ignore the APL & size setting.

PGenerator always need to have RGB-Full (as device settings from inside its interface, as this is the only correct setting for patch generation.)

Then to the software you will use, for example to CalMAN you are using, if you want 16-235, you set from inside CalMAN to generate 16-235, if you want 0-255 then you set 0-255 from CalMAN. For LG use always video levels.

I have examined your LG 3D LUT file generated from CalMAN.

Since CalMAN don't have any tool to examine any 3D LUT data file, the only way of verification is measurements of grayscale/saturation/colorchecker etc.. measurement or checking visually some color reproduction patterns or real content.

For that reason I used LightSpace where it has 3 tools to examine 3D LUT files. (for not entering to more details about these tools, you can see about 3D LUT Viewer, LUT Preview and 1D LUT Viewer details to older posts)









The data are not looking good, the cube shape has many problems to various areas, its completely useless LUT generation, while the same time the 1D LUT viewer looking good (except the usual unnecessary luminance drop (top right), explained again there), I mean there no strange issues (see 1D LUT picture there, because has large size for posting it here)

Its very visible also the Yellow over-saturation bug, which exist to any LG 3D LUT generation from CalMAN for at least 1 year, see more details about the problem there: https://www.avsforum.com/forum/139-d...l#post56558088 or there: https://www.avsforum.com/forum/139-d...l#post56555486

Generally CalMAN can produce better results when you are using less points, as user feedback has shown over the years if you are watching this thread... It's better to use up to 3500 or less (not sure if it will measure 3500 different, but if you enable full logging and open the data files and check you will see if its measured 2-3 times the same patch).

Its not normal with less points to produce better results but its the up to capabilities of the software.

The problems you experience are easily noticed when I used LUT Preview, it will be the same issues as you see to your LG (the following files are animated APNG files, they will swap your LUT ON/OFF per 1 sec....if you don't see animation try other browser which support APNG files):









BTW the issues you have are similar with the other user with projector also there: https://www.avsforum.com/forum/139-d...l#post57787698

Hi Ted, your post always has rich information to read. According to your comment. please verify my setting change correctly for SDR cal.

YES, i can watch it and its very clear a disaster.

Question: Can i re-cal 3D LUT but not to touch 1D LUT ?

PS, i heard LS 3D LUT feature would be better and seems 3dl file can not put into LG directly due to understand casue. Therefore, must need to change format and use Calman to load into LG.
Consider LS has many version , what i should consider to buy since i am not a expert (and will not be), i just want my TV show correct color.

Question: Did LS 3D LUT has autocal similar feature? i don't have such skill to do it manually

To be sure you selected the right black level setting, just switch between high and low while watching a movie or TV program. The setting that gives you blacker black is right.

It is not 'calibration', as we strive for.

Consequently we have chosen to stay away from it at present, as basic manual calibration really does all that can be done.
No point paying for something that can be done for free.

As home HDR evolves I am sure we will add capabilities to LightSpace/ColourSpace, but at the moment that is not the case.

3D LUT calibration is key here.
That is what our focus is - which is why our manual display calibration tools are free.

Steve

I was thinking about this comment again and I can't say that it's incorrect because on the 2016 and 2017 LGs, you are right, trying to calibrate HDR with the tone mapping, etc, was extremely difficult and tricky at best. But with Calman-LG autocal on the 2018 sets forward, the new process is to calibrate HDR at the panels native 2.2 gamma, replacing the factory configuration, and once done the HDR offsets are calculated and loaded to the set removing most of the HDR calibration issues. The process works great every time and the same is used for Dolby Vision. As mentioned the 2019 process has been improved and even lets you do a custom tone map.

And by default, that is not calibration...
You can prove that easily by performing a Verification Profile after the 'calibration.

It's exactly the same as calibrating any SDR display to one gamma, and then post-calibration changing the gamma.
The calibration will immediately become inaccurate...

I'm not sure I agree because the HDR offsets can be calculated and at the end of the day if I take two identical LGs one calibrated with the Calman-LG process and one OOTB or just with the white point set properly, the calibrated set always has elements of it's PQ that are visibly better regardless of the underlying technical details.

Hi, when you are using X-Rite i1Display PRO with WRGB OLED using CalMAN, use the RAW XYZ (which is the factory default calibration table. (since there no EDR table for WRGB but for RGB OLED, useful for RGB OLED Sony post-broadcast displays only.)

When you are using X-Rite i1Display PRO with LightSpace, there available EDR for WRGB OLED, its been used an FSI post-production WRGB OLED for that EDR file generation (which is equipped with LG WRGB panel)

YES, i can watch it and its very clear a disaster.

Question: Can i re-cal 3D LUT but not to touch 1D LUT ?
Yes, you can keep your 1D LUT and re-perform 3D LUT.

Consider LS has many version , what i should consider to buy since i am not a expert (and will not be), i just want my TV show correct color.
LG TV is not supporting direct *.3dl file upload. That file format is just a file format CalMAN decided to use for LG.

Internal TV LUT table is 0-1023, when CalMAN released for support for LG 2018, it was generating 3dl file 0-1023 with black at 64. Because there were some issues to LUT generation, with some invalid data below 64, which producing issues, CalMAN decided to generate 64-1013 3dl file (so to prevent possible issues below 64). But when you select to upload a 64-1024 3dl file, CalMAN is scaling first to 0-1023 and then its uploading to the TV. So it will not send 1:1 the exact data the 3dl file will be include, since its doing a scaling first.

When you will use LG Template with DeviceControl, LightSpace will export the file as exact LG want it. (no any scaling involved)

AutoCAL is 1D LUT capability of CalMAN, its not based to any kind of serious color science since its based to quesswork and multiple measurements of same point many times, one by one until it will see low dE...and then will move to another point. Since if you run 5x AutoCAL in the raw using the same display, the results will be different, its more than a lottery calibration, to be lucky to get better results to one of these 5 AutoCAL's.

See more about AutoCAL here or here.

LightSpace is taking 33p grayscale measurements, you feed its engine with that data and its generating at once the whole correction for the complete grayscale at once, so its keeping the changes to be linear from one adjusting point to another, so gradation will be smoother and it will help later the 3D LUT generation that fact also.

You can see how you can do 1D/3D with LG there:https://www.lightillusion.com/devicecontrol_manual.html

Aha. I think this is the problem. If you are sending RGB Full 0-255 patterns to the TV, you need to tell Calman this and set Luminance Level=PC (0-255).

This is the setting where you tell Calman what levels your pattern generator is sending it.

So (I think) the options are either:
Raspberry Pi RGB Full + Calman Workflow basic options: Luminance level=PC (0-255) - this will be "bit accurate".
OR
Raspberry Pi RGB Limited + Calman Workflow basic options Luminance level=Video (16-235)
PGenerator (at device settings) need to have RGB-Full all the time, no other setting is correct. RGB-Limited will compress the levels and the RGB triplet generation will be incorrect.

You just use RGB-Full (from device all the time, its the default setting) and you manage the levels from the software you will use.

For example in LightSpace (you have 3 options) you can set patch scale 16-235 (if you need RGB-Video) or 16-255 (if you need RGB-Video Extended) or 0-255 (for PC Levels).

With CalMAN It has 2 options, 16-235 or 0-255.

Is this wording correct?
Raspberry Pi RGB Full + Calman Workflow basic options: Luminance level=Video (16-235), make sure the TV has "Black Level=High" - this will be "bit accurate".
OR
Raspberry Pi RGB Limited + Calman Workflow basic options Luminance level=Video (16-235), make sure the TV has "Black Level=Low" - this will not be "bit accurate".
When you have Black Level = High, TV expect PC Levels black.

When you have Black Level = Low, TV expect Video Levels black.

The correct settings is Rasberry Pi RGB Full (CalMAN Video Levels) and LG Black level @ Low.

John, WRGB OLED's using any way of any software, they can't be calibrated at whole luminance range, period, its not involving what software you will use, this will never change, unless OLED's become RGB and the power supply or panels will be better so drift of the panel during HDR mode is a lot of less ans output is more stable.

If you take measurements of drift with LightSpace, you will see that peak white is going +-200 nits up down when you take measurements over one hour, so this is happening during movie playback also.

You can see here and more info about OLED WRGB color volume issue in HDR mode here.

Can I use that same meter correction file I created using SDR patterns to calibrate in HDR as well? Or do I need to create a separate profile using HDR patterns?

Thanks
Hi, when you are creating meter profile, use wide gamut (native panel) in SDR mode (not the Auto, because Auto will select the factory Native Panel -> REC.709 mapping).

Because in HDR10 mode, the panel is using differently the W-subpixel (compared the SDR mode), ideally you need to create a different meter profiling in HDR10 but at 100 nits (so using 50% Luminance Levels patterns).

You can see that if you have some custom RGB balance settings using 60p signal (with PC icon active), when you will send 24p signal the custom settings will go back to default ones. When you send again 60p signal, your custom adjustments will be there again.
