This thread is dedicated to the calibration and user settings for the 2021 LG OLEDs. This discussion is targeted for more experienced users and not for beginners. The individual calibration software forums are best suited for beginners.

This year LG will be offering the following models:

Series	Sizes (inches)	Resolution	Evo panel	Gallery design	Processor
Z1	88, 77	8K	No	No	A9 Gen 4 8K
G1	77, 65, 55	4K	Yes	Yes	A9 Gen 4
C1	83, 77, 65, 55, 48	4K	No	No	A9 Gen 4
A1	77, 65, 55, 48	4K	No	No	A7 Gen 4

New features:
1) New EVO Panel. Next Gen panel from LG Display that is supposed to produce 1,000 nits at D65 white point. For G1 only.
2) New Processor. A9 Gen 4. (Not in the A1).
3) Game Optimizer. You can pick the genre of game you’re playing to have presets applied or customize everything to your own liking.
4) Cloud Gaming Built-in.
5) New LG OS 6.0 with new Home screen.
6) New Magic Remote with NFC connect to share content between your smart phone and the TV.
7) Gallery stand for the 55 and 65 inch sizes.

It will be interesting to see how each of these set calibrate and perform and what "tricks" may be necessary to get the best picture quality. These sets are expected to be incrementally released in the March-June time frame.

Although the 2018, 2019 and 2020 LG OLEDs have advanced calibration capabilities which have been similar, this forum will focus on the 2021 models.

I calibrated a LG 77C1 using Calman 2021. I did a 27pt 1DLUT and adjusted the Shadow Detail then a Fixed Grid 9 3DLUT. I used my Klein K10A profiled to a Jeti 1501 spectro.

I had a little extra time to "experiment" with the C1 and had the following observations when calibrating SDR.

1) Interestingly, LG calibrates the White Point at the factory to the Modified Judd Offset (MJO) of x=0.3067 y=0.318
The first attached pre-cal scan shows what the set looks like with CM set to D65 and the set calibrated from the factory with the MJO.

The second attached pre-cal scan shows what the set looks like with CM Set to the Modified Judd Offset. Notice how much better the set looks from the factory when measuring with the MJO WP.

Note, you can go into the Service Menu and set Warm to D65 and it will look very good as well as shown in the 3rd scan.

2) There are lot's of reports that OOTB the C1 looks dim and or has crushed blacks. In all scans and highlighted in the 3rd scan you can see how the set is tracking significantly below the PQ curve quite a bit. Once calibrated, this is corrected as you can see in the post-cal scan.

Everything set to D65

HDR calibrated well now that CM uses the Aurora engine for the Matrix LUT if you want to use it. HDR Cinema peaked out at around 710 nits where HDR Filmmaker peaked at approximately 670 nits. About 40 nits difference and i don't know why given everything is set the same. Several reviewers reported this as well.

Dolby Vision doesn't calibrate any differently than my CX. The calibration results and PQ are about the same. Some reviewers are reporting the G1's DV may look a little brighter due to the panel's higher peak luminance. My guess is the DV engine is basically the same.

At the end of the day the C1 calibrated very well and when looking at verification content everything looked good. I didn't notice any grid effect and banding and tinting were "acceptable" on this set.

The Fixed Grid9 3D LUT looked good in the LUT viewer with no obvious problems. I just forgot to copy it out. I'll post a sample on the next calibration.

Finally i took a Spectral Power Distribution scan of the C1 below. The last scan is of the A90J for comparison. They look pretty close. I know there is a lot of discussion over which sets have the new Evo panel but i've not seen any reports of the Evo panel improving the picture quality performance so it may be moot on which panel your TV actually has. One thing i'm curious about is LG was advertising that the G1 will have the brightest and most uniform panels. Once we get to look at some we will be able to see if this is the case.

I'm getting ahead of myself here, but with the evo panel having different emitting layers, that would mean the spectral power distribution would be different on that model right? Which would mean a new alternate white point would have to be found for the G1 series (and any other series using the new panel)?

 

[Rolls-Royce]

Not necessarily.

It's fruitless to speculate. We will have to wait until we can look at some of these panels.

Does calman or colour space CMS support LG 2021 OLED right now?

Calman 2021 beta supports the C1/G1

 

[Hotneca]

Calman 2021 beta supports the C1/G1

I have the video pro license,and filled out the form for beta.
But, there is no response.
I really want to join the beta test,as I have LG C1 now.
My calibration tools is Klein K10 and JETI 1501.
Thanks!

mr Wifi-spy, any new calibration features we might see on these new TVs with Calman? Any changes to autocal?
(now... the waiting game... i'm replacing my 77 c9 with a 77 g1. I'm not really expecting the TV to be any brighter (my c9 was already ~750nits 10% window) - but am expecting the g1 to be a keeper for a few years.)
It is a shame the $$$ jump over the c6 hrd2000 meter to the K10-A is so large. Is there a middle option? (or, in the end, i'm good with the c6)

Nope, no meter in between the C6HDR2000 and K-10A, price-wise.

 

[zielin]

Thanks. Shame one can't rent the K-10a for a few days. poke poke B&H ;D

the EVO screen has "improved color accuracy" - I wonder what the means. Generally? or as parts of the screen changes temp during use there is less impact?

 

[Classy Tech]

Ive asked in other threads, but haven't gotten any answers. I have a xrite i1 display pro plus and going to get the calman home for LG software. Don't have any budget left for any additional tools.

Do I more or less use the same settings as the calman tutorial video for the 2020 models (except changing it to the 2021 C1)? And should I use 3D lut or something different?

Also should I be doing 2.2 gamma and D65 for SDR, gaming and bright room modes, and bt.1886 D65 for dark movie watching?

Calman for the 2021 models is the same as the 2020 models. The only thing you will do is use the Calman 2021 templates when you connect to the TV. Just follow the tutorial and when you get to the CMS section of the workflow use the Fixed Grid 9 3DLUT. On the OLED use Gamma 2.4 for dark room and 2.2 for light room. BT1886 is the same as 2.4 with the OLED.

Any recommendations on a spectrophotometer/calibration device that's around 500$?

Thank you for the update! I always enjoy reading stuff from you guys who know what you're doing.

My only thoughts on the C1 having the new panel would be that it might be less prone to burn-in than the previous panel since it's more efficient and doesn't need to be driven as hard. Is my thinking correct on that?

Also, what white-point did you settle on if you don't mind me asking?

personally 710 nits in cinema hdr calibrate I find that very good.

when did you think about jrref overall for the quality of the C1 image?

The picture quality on the C1 is very good. I just would have preferred that LG got the near black processing tracking properly out of the gate. I'm not sure why they made it track that way unless they want to crush any near black flashing and or artifacts.
