First of all. Thank you for spending your time to my calibration experience.
Some infos about my situation:
1. The Eizo is a SRGB Color Gamut Display.
2. I checked the eizo with the ipro3, with the display3 with and without profile and everytime I'm very near at D65.
3. I have set my LG77C9 to the eizo by perceptual matching
4. Then i measured 100 IRE on Eizo and took this whitepoint as my AWP. And this AWP is nearly the same coordinates like Ted's.
5. So i calibrated with SM WB this corrdinates to 80% IRE (Because of Linearity) to the LG77C9 and did the rest with the 22PT. it looks great like never before. every content now looks the same on both.
6. Then Dnice said it is not necessary to do it, because the 77C9 is great at D65.
- I know that you are much more advanced than me. But in my defense I have to say I'm doing it also for 15 years with projectors, Monitors and TV's. So I think my Eizo is really at D65.
7. Ok, calibrated my 77C9 to D65 again to verify. It looks really really coolish against the eizo. To much red and blue to my taste.

So there are some options why it could the case of the difference.
1. I'm doing all wrong from the beginning
2. My measurement equippment is wrong
3. The 77C9 from Dnice (I think it's a US Model like Ted mentioned) is not like my EU Model?

At the moment I'm satisfied with my and Ted's Ipro AWP coordinates.

But since I know that Dnice is a professional and his testimony should not be neglected, I will research it further

Maybe i will find out..

So one question makes me confusing:
Why does a 77 behave differently with AWP than a 65 or 55?
What is the model number of your Eizo?

I really do wish there were others out there with 5nm spectros and owned a 77 and a smaller OLED to compare side by side. More data point, the better.
I may (actually will) have the opportunity to visit my local specialist A/V Retail store at some point in the future here in U.K. I get on very well with the manager and the all the staff, so it could be possible that it is something I could do, but it will not be until the current situation with COVID has subsided. I will be glad to report anything I find if/when I am able to do this.

When you are using an 80% pattern in SM WB, it's wrong, as you will not fix clipping issues, which can appear in levels above 100%.

LG is using 80% because they have to perform a quick RGB balance calibration using one Point only.

When you want to fix RGB balance errors using one Point only, then you have to aim by calibrating the middle Point of the Luminance.

The panel is Gamma 2.2 calibrated from LGD.

When you aim for 100 nits in 100% White with 2.2 gamma, the 109% should have 121.2 nits as target Luminance.

The 80% Gray has 61.05 nits target.

So 80% Gray is the middle Luminance range of the whole grayscale since it has 50% of 109% Super White's luminance.

It's the reason I recommend for years to calibrate 109% in SM WB with LG TVs.

At the moment I'm satisfied with my and Ted's Ipro AWP coordinates.
They are Leon's cordinates from his i1PRO vs. JETI testing.

I know that CX 77 and 48 are cut from the same OLED 'glass' in China factory, while the 65 and 55 from the same OLED 'glass' in the Korean factory.

1. So an Ipro3 at the end is useless?
i1PRO3 is the best Spectro for a home enthusiast.

It requires a regular software license level to operate it, not a professional software license level.

You have all the gear to your hands to perform the display matching, but you haven't explained if you will apply 3D LUT to the EIZO also,

You can't match two displays only with a white point calibration.

Is there anything that I should keep in mind if I were to try out alternative white points using Service Menu WB and 2-pt WB adjustments other than targeting for other coordinates?

I believe there are not 100% in all Levels the same. But just visually in any content i have seen they look very similar.
The Eizo has only gotHigh Gain WB. No Luts possible.

LG is using 80% because they have to perform a quick RGB balance calibration using one Point only.
Afterward i checked the 109% there is no clipping and 100IRE is at 100 Nits.
I'm now using the SM WB for 80% because than the whole rgb balance looks more flat and i don't have to touch the 22WP so extremly.
And i'm starting with 100 IRE to set the 100 Nits Luminance.
this is what i have done with my projectors.
I know that everyone said this is needles for Digital TV's. But for me ist makes more sense before starting the22WP and the curve is more flat overall.
Maybe at the end the results are the same...

Yes. Thats as it is. And in the first session i have calibrated to gamma 2,2 and after that to BT1886

So 80% Gray is the middle Luminance range of the whole grayscale since it has 50% of 109% Super White's luminance.

It's the reason I recommend for years to calibrate 109% in SM WB with LG TVs.
Yes. But as i said in the other thread. After setting 109 with SM WP the 100% IRE 22WP in usermenu is adjusting the High Gain again and the 109% is not anymore in the ballpark. So i have to choose:
1. Setting 109% WB in SM and starting the 22 WP in normal menu at 95% to let 100% untouched (then 109% is correct but 100% not)
2. Setting 109% WB and starting the 22 WP at 100% (than the 100% is correct but 109% isn't anymore.

Check it out! :)

Ah, ok. Thanks Leon

I know that CX 77 and 48 are cut from the same OLED 'glass' in China factory, while the 65 and 55 from the same OLED 'glass' in the Korean factory.
Thats interesting. So when Dnice is right the 48CX maybe also don't need an AWP?

Thank you all for yur help.
You are all very kind to spend your time to help Amateurs with your professional knowledge.

You can't have both calibrated 100% and 109% at the same time when you use regular/SM controls.

Just balancing 109%, you prevent some stuff you can't see with grayscale, but it will prevent clipping of WTW.

109% in SM RGB-Gain and then 0-100% with 22-Points is the correct procedure.

What method are you using to generate patterns?

Do you see a difference in luminance between 109% and 100%?

I did this. But as i said. Adjust7ng 100ire 22pt will affect 109% sm wb.

Yes i see and can measure. 100nits 100ire and dont know exactly at the moment but higher as 100 nits. 114 or 120. Cant verify at the moment.

Pc rgb high
Tv rgb low
Pattern: Calman client running on pc and connected by ip to calman on laptop. Not expanded to pc levels.

But for me it's logical. 22pt 100ire adjust the high gains like high gain wp in sm. So youll have to choose correct 100 or 109 ire.

The patch generator solution you are using is not recommended because you have no proof that your PC has bit-perfect output.

ICC, VCGT, GPU enhancements can alter your output levels.

Invest in PGenerator to be sure that you will always be able to generate any bit-perfect RGB triplet.

IP connection with TV means that you are using iTPG of C9, which is an inaccurate and not recommended TPG solution.

No i mean the calman client 3 pattern generator not the itpg.
As i remember the calman client gives me the same result as the LG ITPG.
I have to verify again.

So we can't use the ITPG? for what is it worth than??? Everybody is using it with calman home???

But i thought it's best to send the Test Patterns from the device which I'm using... So i used the PC as a generator.

For the P Generator i just have to buy a raspery and download the image from light illusion?
can i use the p generator with calman?

Whats really intersing. I can see here are real professionals. But i it's very quiet from calman & lg support here. I believe calman and lg could do a lot about bugfixing and better functions if they would listen here a little bit more instead of being ignorant.

If you are looking for Calman Home for LG discussions there is a separate thread of that. Also our official support channel is via the support area of portrait.com

Ah ok. Sorry about that. I thought this is the official forum. Than i will take a look there. Thanks
