  • New Dolby Vision Custom Calibration file to apply via USB patch (updated on April 2019)
  • HDR Game mode back to a new custom profile based on HIGH Dynamic Contrast to match the new improvements
  • Added new in-game HDR suggested settings

Please not that this re-calibration goes in-depth also for all White Balance + CMS values, so do not forget to also update those sections when possible (and do not forget to also update the entire DV profile using the new USB Patch!)

Then give those completely fresh settings a try and let me know what you think...
Why OLED light to 70 in SDR modes? With just an X-rite i1 Display Pro for 120 nits, I've never had to go above 35 OLED light.

Because I found any SDR OLED Light value under 60 too dim for a medium-lit room (therefore for a day/night mixed usage).
I also found that SDR Game luminance is a bit dimmer compared to SDR Technicolor's when using the same OLED Light value.

Same here. For SDR, OLED light at 35 is my sweet spot for my moderately bright room. Anything higher starts to look unnecessarily garish.

Ahh okay, cool. Just wondering.

Also, why gamma 2.2 wherever it isn't locked rather than bt.1886 in SDR? My understanding is that for most SDR content, when played with a display that has essentially perfect blacks, bt.1886 is most likely the standard adhered to. As outlined here briefly:

Because unless you're playing in a pitch-black room 100% of the time, BT.1886 will hide too much the darker details, giving the impression to be black-crushed all the time on medium-lit rooms (even if not so).
Gamma 2.2 is much better for mixed light conditions' usage.

HAPPY EASTER!

The settings below are ALL NEW and vary from slight updates to more than slight.

At this point, I'm thinking that our 7 series OLEDS are probably approaching 3,000 to over 4,000 hours of viewing time. My C7 has 4,000+ hours on it, and is our everyday workhorse. Recently, I noticed that blue had fallen off, so I decided to fully recalibrate SDR - [technicolor Expert], Dolby Vision - [Cinema (User)], and slightly updated HDR10/HLG [technicolor Expert].
Here are the new settings in all their glory. They may help "resurrect" the picture quality of your 7 series. ( Sorry for the Easter themed play on words ).

Dolby Vision notes: This new "Easter '19" Dolby Vision calibration looks the best so far. There is better lower and mid-range luminance performance which further helps with eliminating the “darker” look of the “Cinema (User)” picture mode, while still providing all those spectral highlights. The colors look much more natural now as well.

The Calman “DV custom" workflow allows the calibrator to create a special file just for 2017 LG OLED’s, which is saved to a thumb drive and then loaded into the TV. Spectracal, Dolby, and LG worked very closely together to create this awesome workflow.

NOTE: Below, I have written a quick "how to" with instructions for making your own DV calibration file. This way you can install without needing to PM me for the file. Over the last several months, I have received literally 100's of requests for this file, and it has become a bit too much to manage and also juggle things with my day job. So, if you are somewhat computer savvy and know how to create a plain text file, you should not have any problems cooking your own DV calibration file. If you still need me to send the new file, feel free to PM me with your email address, and I will send it off. Just trying to lighten the load a bit.

PERSONAL OBSERVATION: I am really enjoying the new settings. The thing that strikes me the most is how SDR almost takes on the characteristics of HDR.

HDR10 Settings
HDR-10 Picture Mode: technicolor Expert

BASIC SETTINGS:
OLED LIGHT: 85 (Default: 100) -- This setting will vary depending what nit levels the content was mastered as well as room brightness. There’s not really a way to know the mastered nit levels of any given title without a Lumagen which can read the metadata. So this is really a “how does it look to you” kind of thing. The 85 setting seems to be a “happy" medium, but there's also eye comfort levels to consider.

------------------
THE DOLBY VISION CALIBRATION FILE

1) Create a plain text file and name it as follows WITHOUT the "quotes":

"DolbyVision_UserDisplayConfiguration.txt"

2) Copy the following and paste into the newly created text file. Be certain to REMOVE the "quotes":

"# Dolby Vision User Display Configuration File
# Generated by 5.9.2.59 on 3/19/2019
# Display: Unspecified
# DM Version:
PictureMode = 2
Tmax = 759.590301184834
Tmin = 1E-11
Tgamma = 2.2
ColorPrimaries = 0.6776 0.3223 0.2604 0.6666 0.1422 0.0556 0.3127 0.3290
TLMS2RGBmat = 4.19055329601013 -3.3243228097014 0.133769513691273 -0.92778533729114 2.08407932269406 -0.156293985402918 0.0691538802229898 -0.155635576827132 1.08648169660414"

3) Save and copy the file to a blank thumb drive that has been formatted as "FAT32".

4) To install, start by playing Dolby Vision content on the TV, and ( IMPORTANT ) set the picture mode to “Cinema” and NOT "Cinema (Home)”.
Next, plug in the thumb drive into USB port on the side of the TV. (Make certain that there is nothing on the thumb drive but that file. No folders, etc.) You may have to go into the Photos & Video prompt, and then close ( X ) it out in order for the TV to recognize the DV calibration file. In fact, I finally yanked out the stick - plugged it back in - and then finally got the prompt from the TV. If you still have problems getting the TV to recognize the file, you might try power cycling the TV. Finally, several of our other members told me that they had good results after formatting the thumb drive as a FAT32 Master Boot Record.

Once the TV recognizes the file, you will be asked if you would like to install it. Answer "Yes" and less than a second later ( it's a very small < 1K ) the file is loaded.

The TV will then respond that the next time you load Dolby Vision content, it will load the new settings. And you are done.

Eject the thumb drive and enjoy.

After a year of trying, I give up. I couldn't make the calibration file work on my TV. I tried everything during an entire year, all the tips and tricks (multiple USB drives, filesystem format and so on) but I never got the "popup" to appear. I always get the multimedia popup (that I quickly close) but never the DV one. The USB drive always ends up with a folder called "LG Smart TV" and a mysterious file called "$TXRAJNL.DAT".


Is anyone on the same boat? Maybe my TV has some configuration that prevents this change? (American 55C7P)

I had to format the drive as a Master Boot Record before the tv recognized it. I checked the drive after loading it into the tv and it also showed "LG Smart TV" which was not there before inserting it into the TV. Not sure what to say except keep trying it took me more than several attempts before it finally worked. After you copy the file to the drive all that should appear is what you copied from his file in the post.

My god. Thanks a bunch! I realized I had to set the "boot" flag to the partition. Here's what I've been doing all this time: GParted > New Partition Table > msdos. But after editing the partition and adding the "boot" flag, as I said, it finally worked! Thanks!

My oled LG 2017 got washed out colors and yellowish tint after latest firmware update 05.80.15. in HDR HLG 60hz via HDMI with Sky Q in Italy. I had to switch in PC mode with 4.4.4 chroma sub sampling to watch the correct colors but I think my tv works at 8 bit due to limited bandwidth of his HDMI ports 2.0b. I’m very disappointed, my tv doesn’t work correctly and nobody talks about that, it’s a big issue, more than black crush or other and LG doesn’t do anything to fix it.

Yes, in HDR HLG 4k 60hz via HDMI doesn’t work correctly, unnatural colors and yellowish tint. A complete disaster.

I am wondering if there is anyone with some actual pull with LG who can make sure this is being properly addressed. This problem is pretty severe and affects equipment that is distributed by the primary pay TV broadcaster in Australia.
In Italy with Sky we have the same issue. I wrote at local support LG but four months are passed and nothing happened. Such a shame!

So there’s still no fix for dim hdr game mode? I tried solutions online like putting dynamic contrast to high or switching to pc mode but all those do is blowing up bright highlights.

The only true fix would be to run your content through an external converter and force the tv to think all the content coming though is 1000 nits.

In Switzerland with the UPC TV Box it's the same issue. A workaround is to configure the TV Box to output 1080p, then the colors are correct. Luckily there is just 1 channel in 4k and that one is in the optional sports package, so I don't miss out anything. I don't use the Netflix app on the TV Box, so it really isn't a big issue for me, at the moment. But yeah, I would hope for a fixed firmware. Also wrote local support some months ago.

It’s the same with Sky Q but there is a lot of football in 4k hdr and the Formula 1 and some tv series or documentary and i’m really interested in it. In my opinion it’s a scandal, we paid a lot of money for a 4k hdr tv and we can’t use it to watch 4k hdr content. If i wanted to watch at 1080p i had keep my Pioneer Kuro and save 3890,00 €.

  • New Dolby Vision Custom Calibration file to apply via USB patch (updated on April 2019)
  • HDR Game mode back to a new custom profile based on HIGH Dynamic Contrast to match the new improvements
  • Added new in-game HDR suggested settings

Please not that this re-calibration goes in-depth also for all White Balance + CMS values, so do not forget to also update those sections when possible (and do not forget to also update the entire DV profile using the new USB Patch!)

Then give those completely fresh settings a try and let me know what you think...

Does this profiles apply to PS4 and Switch (in this case just the SDR profiles) as well? Do you have your TV sent to PC Mode? I've heard that in order get Full Color Space to work right you need to use PC mode.

Im using these settings on my PS4 Pro (SDR and HDR) and on my Switch (SDR) and i think it works really good.

Yes, as long as you set PS4 Pro similarly (RGB Limited, then all other video settings to Auto).


Avoid PC Input altogether, as it has color banding and input lag issues in HDR.

Just got a C9 65" to replace my C7 65". Will let everyone know what I think after a few days of tinkering.

Looking forward to it. I’m using the c7 and I find brightness is lacking in hdr contents. Wonder if c9 will be substantially brighter.

C9 First Impressions vs C7. 65"

First impressions of how the C9 compares to C7. (~3,000hrs with C7 and ~7hrs with C9 in the same dark, light controlled environment)

TL;DR: If what you care about is very critical image fidelity, menu and app navigation responsiveness, game mode HDR brightness in all content, it feels like a genuine upgrade from the C7. Cleaner, sharper, faster, smoother. Anything older and the gap is even wider. I'm surprised. I just hope I can sell my C7 for over $1,000 because boy is it expensive (spent $2700 on my C7 2yrs ago from eBay). HDMI 2.1 is a cherry on top to look forward to. Currently I have no way of testing the performance there.

Physically, heavier with a more subtle stand that I prefer. Grey backing & stand look a lot nicer, imo.

Feels a bit larger due to the bezel's size decrease (I think it's from 1.1mm to .9mm).

Navigating the menu is much snappier, close to instantaneous.

TV internal speakers surprisingly decent.

Coming out of black is much nicer, near black no longer crushed, even when bt.1886 is engaged in SDR. (This is a huge + for me. I returned a B6 because of the crush and even the C7's amount of crush can get irritating.)

Image processing produces all around better images, especially concerning lower quality content. Noise reduction features work quite well without introducing too much negative consequences like smudginess. The smooth gradation option low - high work quite well without ruining sharpness. It works especially well in older video games that have been given an HDR update (Halo 3's skyboxes can get pretty blocky.)

Screen uniformity, OLED 'streaks or striping', color cast in white. Much better, at least with this particular panel. Grey uniformity is perfect, whereas my C7 (which I also got lucky with) had some noticeable OLED vertical striping. White seems more punchy and clean, even at the same output of 120nits. My C7 can have a noticeable yellow blotchiness in 100% white; this C9 seems to veer toward magenta but it's much less noticeable and at first glance feels more pristine. Only when really dwelling on it is it noticeable. The C6 I had was terrible in each area. My C7 was near flawless. This C9 is as flawless as one could hope for, with only one vertical banding streak on the mid-left side, very rarely noticeable even when dwelling on it.

Motion performance in all areas seems improved. Black Frame Insertion in 60Hz+ SDR content is quite cool as it substantially improves motion resolution. 30Hz content, like Bloodborne on PS4 Pro, is very flicker prone and unusable. (OLED light at 85 maintains 120nits with BFI).

Game mode HDR is, or rather feels, substantially brighter yet still looks "right." It's hard now to tell any difference in fidelity from Game mode and ISF HDR mode. I love it. Checked with games running on a 2080Ti PC and PS4 Pro. Mortal Kombat 11, Forza 4 look stunning. Spiderman, Gran Turismo Sport, Horizon Zero Dawn, The Last of Us, all look dramatically better, imo.

Game mode SDR also looks indistinguishable from ISF modes, but why this couldn't be changed in previous models with software update boggles the mind. The Wide gamut game mode lock in previous models is really annoying.

Input latency with a PC in desktop (4k, 60p and 1080p, 120p) is fast and frankly hard to tell as nearly double the C7's (~21ms - C7 vs 14ms - C9). Even when side by side with a 144Hz, 1ms TN panel. The C9 feels equally as fast as that panel where the C7 maybe felt ever so slightly more sluggish. I thought this would be easier to feel but it's actually not quite as noticeable, but I'm glad it's faster nonetheless.

Basic SDR calibration:
ISF Dark Room and Game mode:
OLED Light 34 (120 nits)
Color Temp: Warm 2 with High Gain Red -6 (6500k)

Displays: LG 65" C7 | LG 34UM95 | LG 27UD88 | Asus VG248QE 144Hz | DELL S2240m
Sound: Yamaha HS7's | Onkyo TX-NR 646 5.1.2

Thanks for the impression.

Do u notice any problem reported on the c8 like macroblocking, luminance fluctuation, elevated black or picture wrongly dimming down over time during dark scene?

So far no, nothing stands out regarding any of those, but some of those artifacts and behaviors are scene and content source dependent. It could be that I've yet to see it here and there. Overall this is the cleanest, sharpest, most impressive OLED I've seen yet of C6 and C7.

# Display: Unspecified
# DM Version:
PictureMode = 2

3) Save and copy the file to a blank thumb drive that has been formatted as "FAT32".

4) To install, start by playing Dolby Vision content on the TV, and ( IMPORTANT ) set the picture mode to “Cinema” and NOT "Cinema (Home)”.
Next, plug in the thumb drive into USB port on the side of the TV. (Make certain that there is nothing on the thumb drive but that file. No folders, etc.) You may have to go into the Photos & Video prompt, and then close ( X ) it out in order for the TV to recognize the DV calibration file. In fact, I finally yanked out the stick - plugged it back in - and then finally got the prompt from the TV. If you still have problems getting the TV to recognize the file, you might try power cycling the TV. Finally, several of our other members told me that they had good results after formatting the thumb drive as a FAT32 Master Boot Record.

Once the TV recognizes the file, you will be asked if you would like to install it. Answer "Yes" and less than a second later ( it's a very small < 1K ) the file is loaded.

The TV will then respond that the next time you load Dolby Vision content, it will load the new settings. And you are done.

Eject the thumb drive and enjoy.
After installing DV file, do you use “Cinema” or "Cinema (Home)" to watch DV content? Which one "Cinema" or "Cinema (Home)" that file affects?

The file only affects "Cinema" and NOT "Cinema (Home)".

Hi John

Thanks for your updated settings which I have entered for SDR and HDR so far - I will tackle DV later.

However, I have recently taken to watching SDR on "HDR Effect" with the 'medium' strong effect. Switching between this and "Cinema" I must say I prefer the "HDR Effect" now (much more vibrant colour and wider black/white contrast). Maybe I'm just a Philistine! After watching in 'HDR Effect' for a while 'Cinema' now looks dull and lifeless. Note: I wouldn't watch UHD Blu-rays in anything but the most faithful reproduction of the Director's intentions but as most of my SDR viewing is 'casual' free to air TV I don't think that faithfullness here is necessarily paramount.
