Well my first exp dark SDR autocal seemed to work. Not much luck in HDR.
No IRP 3dlut creation, no lut uploads, madvr control is wrong (exclusive fullscreen mode is erratic).

I ordered a raspberry pi though perhaps that will be more useful...

Thanks Tyler, couldnt remember if i ticked myself "use native gamma for gamut target"

I redone some hdr calibration with a good profile and i find the hdr peak brightness to be dead on 700 nits so i thought that having this option ticked gave me this result.
I used to find after calibration 750 nits.

I've stumbled upon this thread in quest for greater near blacks on OLED: https://www.avsforum.com/forum/40-o...hnology-flat-panels-general/2579537-lg-oleds-how-enhance-near-black-detail.html

I know this thread is for a lot of advanced calibrations, but is there someone who can do a nice summary of what needs to be done, like a quick 1, 2, 3 of what settings to adjust on the TV?

Below are my settings options and that I am trying to figure out how I should be adjusting things based upon reading through the above thread. If anyone can help me out by talking me through what I should be changing, and then viewing the slide or batman shot they talk about, I would appreciate it. I really want to get a bit more black details at the lower end of the gamma curve, and not across the entire range.

In addition to help getting started, I have posted some questions beside settings below that would be helpful for me. Thank you.

Picture Mode, Expert Controls
Color Temp, Cool, Medium, Warm1, 2, 3
Method: 2, 10, 22 ire - What does IRE do here?
Point: low and high - What does these do?
Red
Green
Blue

Color Management
Color, Red, Green, Blue, Cyan, Magenta, Yellow
Saturation
Tint
Luminescence - What does this setting do?

Peak Brightness - Does peak brightness limit the amount that the highlights get in the image?

Gamma

Color Gamut

Is it normal to have considerable greyscale discrepancies across HDMI inputs? HDMI 2 tracks excellent on my set, but HDMI 1 is notably worse. Double checked settings are the same on both inputs. I thought I had a source issue with my HTPC until I tried different inputs. Haven't checked the other HDMI inputs yet.

I posted this on the owner's thread and got no response so I'm hoping someone on this thread will respond?

I'm noticing on SDR content that the white or very light areas of the screen look like snow (for lack of a better word). It looks like a bunch of tiny little dots (maybe pixels?) on those areas of the screen. Is there a video setting that I can change to get rid of that? I currently have it on:

Picture mode: Expert(Dark Room)'
Brightness to '54'
Contrast to '90'
Sharpness at '0'
Color at '50'
Tint at '0'

Dynamic Contrast and Super Resolution 'Off'
Color Gamut set to 'Auto'
Gamma to 2.2
Color Temperature: Warm 2

I don't notice this at all when watching HDR-10 or Dolby Vision content.

Are you comparing the same scene in SDR and HDR?

Maybe film grain?

Could anyone experienced in Calman let me know if calibrating modes are independent of each other? As in, is it necessary to calibrate SDR first before any HDR or it doesn't matter?

Also, if auto cal workflow ends with 50 brightness and 85 contrast when setting the final luminosity at 100 for sdr and I test the nearblack16-27, is it ok to adjust brigbtness up or does that mess up the calibration? I have to up brightness to 53 to barely see 17.

No, it's been SDR only. For instance I saw it on the Apple TV 4k on one of the Bond movies. I also noticed it on the built-in Prime app when watching the series "Chuck". Both of these are not available in HDR.

To my knowledge, all modes are independent. Not just SDR and HDR but actually each picture mode (isf Expert bright / isf Expert dark etc.) has its own settings and LUTs.

Changing the brightness will definitely change your results of your previous calibration. You can verify it yourself by running another pre-calibration measurement after changing the brightness and comparing it with the post-calibration results. Your deltaE values will most likely be worse after changing the brightness, one tick might not have a big impact though.

Assuming you've also used the de_ITP formula (as suggested by Tyler), the near black results of my SDR calibrations (as said before in this forum) pretty much look the same. And I'm not too happy about it either ...

Sorry. I know the modes are independent. I meant to ask, are DV/HDR dependent on the SDR calibration or can they be done in any order?


As far as near black, i'm concerned about this too as no one has responded to any of my other questions in the Calman thread except for the meter profiling.
If some are saying to follow the workflow and not deviate, I get that. But it's contradictory to some other stuff i've read here about using the test patterns for 16-27. There are some really dark scenes that could use some brightness I have noticed.
For example in Chilling Adventures of Sabrina where there's a black shirt and jacket but you can't tell that they're wearing a shirt. It's just a head and neck and blackness and looks like they're wearing an all black jumper.

If this is truly the director intent, I'm good.. but why are people saying to adjust brightness to barely see 17/18 when this isn't what I'm seeing with calibration?

Hi All,

Just after some advice. I have a LG 65C9 screen and looking to purchase CalMAN Home for LG, use TV built in pattern generator and either:

X-Rite i1 Display colorimeter OEM
X-Rite i1 Pro
Spider X Pro
Spider X Elite

This page lists the X-Rite models however not the Spyder X but previous version: “Spyder 5”.

Any suggestions which is best?

Hi.
I am struggling a bit with the HDR calibration on my LG C9. Bought Calman Home to use with my i1 Display Pro. I am completely new to TV calibration and have just been following the video guide closely, with few changes based on this thread (setting Low Light Handling for the i1).
The HDR result looks off. In a weird way that makes me wonder if something else than the calibration is the issue. I was hoping someone might have an idea based on these pictures.

Picture 1: A picture from Calman during calibration. One weird thing I have noticed is, at the top under LG 2019 OLED it says Cinema, even though I selected HDR Game at the screen where you reset DDC. It never changes the profile shown at the top. Does that matter? It is certainly changing the HDR Game profile during the calibration, as is also evident from the other pictures.
Also, there are a few black spots on the image, outside the white center, which aren't there in the video guide (edit: nvm, theose are in the video too).

Picture 2-3. From an LG test video stored on the TV. The liquid in the bottle is quite red in the uncalibrated Cinema profile (and was mostly the same in the uncalibrated Game profile before). But in the calibrated Game profile, it turns orange. Now, I obviously dont know which color that liquid is supposed to be, but I am assuming it is red.
Video can also be found here: www.youtube.com/watch?v=7Y9nX0QHqzA

Picture 4-5. Test image from some HDR youtube video, www.youtube.com/watch?v=XEtUF7RT3pw
Here the uncalibrated Cinema profile has, washed out colors, relatively to the calibrated profile does not. In a way it gives the opposite impression to the previous pictures. But the big difference seems weird. They clearly can't both be correct.
I also tried the test patterns in Calman. They show the same difference.

P.S. Just to be clear, the pictures here are of course not 100% color accurate to what I see on the TV - they are bad phone pictures after all - but the difference between the pictures are fairly accurate.

It should say HDR Game in the display tab, if not then you loaded the 3D LUT into the wrong slot on the TV. Also, fYI there is a CalMAN Home for LG specific thread.

 

[Shadout]

Thanks. I was aware of the Calman Home thread, but wasn't sure which one was the most appropriate thread. Taking any follow-up questions there instead.

Edit: Just wanted to say that everything seems to be working now.
Always nice when the problem is yourself. So much easier to fix

Just ordered 77C9 and planned to buy also CalMAN Home for LG when I get it and also enough UTT (however didn´t notice big difference with my 65C8 hours 5-200).

I have manually calibrated my sets maby 10 years and got pretty good results with i1DPro meter (without correction matrix against reference).
Now when C9 have internal testpatterns I´m also ready to step autocal.

Found only D-Nice comment about custom white point with autocal.
Are rest of you happy with D65? There´s no need to correct metamerism?

Few alternatives from this forum:
Technicolor x=.300 y=.327
Wifi-spy x=.3073 y=.3214
D-Nice x=.3076 y=.3261 (2017 LG)
D-Nice x=.3080 y=.3296 (2018 LG)
Zoyd x=.3089 y=.3284

One vote for happy with D65. I'm not a pro, but have been an enthusiast calibrator for about 10 years also. You are going to love autocal and results with a 3D LUT!

 

[Make73]

With C8 I wasn´t happy with D65, tried different white points and ended to D-Nice x=.3080 y=.3296

Had several DIY calibrated plasmas and few LCD´s, picture with D65 on OLED seems too reddish for me

Surely with autocal it´s easy to make different calibrations with custom wp and compare which one is for me
