For DV, for the most part, yeah. They might give you an idea of greyscale balance at different levels but with these sets you can't do anything about that in DV. They can also give some insight into the differences in how tonemapping works with different settings, but like I said, that will differ with every different scene in different movies as well. So in that case it's more about relative differences than absolute.

That's why for sets that allow DV calibration they come with their own patterns and reference points for those patterns, because DV changes depending on the set it's displayed on.

Are there saturation patterns? Because those at least would probably be useful in determining the optimal color/tint settings.

Yes there are. P3 in BT2020 50 % amplitude with different saturation levels up to 100 %. This is the 1st Revision of DV patterns so there is more to come. By the way I usually use color/tint settings to optimize skin tones with test patterns.

Ah when doing HDR10 I preferred full BT2020 saturation patterns, not P3 based. But I sort of created by own spreadsheet for calculating which color/tint settings were best, based on a sum of distances from target xy values (I used 10pt saturation patterns). The setting which produced the smallest sum was the optimal setting. The same process worked for both saturation and tint. Using this I was also able to determine which of the gamut settings worked best for each mode by finding optimal color/tint for every gamut and comparing, and it turned out contrary to expectations, Normal was not always the best choice.

Masciola has also come up with HLG calibration patterns...would these be useful for our 2016 sets?

Pretty sure every firmware post 4.31.20 had black glow for most (all?) users. Some say they don't see it but I think they're just not very observant or they're not watching in a completely dark environment, where the glow at 1% IRE or less becomes quite evident. Annoying to have lost one of the features I paid all that money for but there is no perfect tv. You have to think that LG updated the firmware with the idea of improved users' sets, not degrading them. The most recent firmware restores bright HDR game mode (although I think 4.31.20 was one of the last ones before the infamous 'dim' HDR game mode was introduced). Supposedly, the black level tweaks were introduced to increase shadow details and gradation on the low end that may be limited due to the B6's inferior processor. Not sure how true this is, as I was unable to do a before and after comparison. But I can say with confidence that the zero blacks are gone, and no amount of tweaking can bring them back.

I took your advice and have had my tv disconnected from the internet. I also moved, but never connected it.

That is until a friend staying at my place decided to log on to watch hulu, the update got installed and now I have bad black glow.

It's more or less ruined the tv. The blacks are all grey now and I have no idea what to do. I also don't have a PC to even start the roll back procedure.

This TV may as well be an LCD now

Doesn't HLG use the same mode/settings as HDR10? If so they probably aren't necessary but you could use them if you want.

Yes you are correct....watching the 4K HLG telecast of the US Open golf now and indeed HLG does use the HDR10 mode.
I’m with you in saying that Masciola’s DV and HLG patterns don’t really add much value to our 2016 sets (unfortunately)...

@tendies - Post 27935 may be the most brilliant example of a First World Problem post I've seen this year.

I'm happy to take your ruined TV off your hands for $200 (low price because you acknowledge that it's ruined).

JustinHEMI05 06-16-2019 01:36 PM

Been a long time since I checked in on this thread since getting my 65" B6 Chad B calibrated TV and it's coming up on 3 years since I got it. There's nothing wrong with my TV, it's still superb, but 3 years is about when I start looking to see if it's time to upgrade.

Has anyone gone from the C6 to the latest LG offerings? Do you feel there was significant improvement over the B6?

Also, I see that there's still an enormous price increase to go to 77". I want a bigger one but am not willing to pay current 77" prices. Perhaps it may be better to wait until those prices come down before upgrading again.



ETA: Correction to calibrator. I got mixed up, it was Chad B.

As if I wrote the first temperamental post on a home theater forum.

I stand by what I said, if I can't roll it back, it's ruined by the virtue of it no longer provides what I paid extra for. Also annoying as I've kept it offline in years to avoid this and someone else connects it and screws it up.

I also work in film, I'm hyper sensitive to things not looking right.

It's yours if you want to come pick it up.

For me these DV patterns were a godsend. I finally got to learn precisely what is going on with B6 DV white balance and got rid of the green cast that prevented me enjoying any DV content.

Interesting. I'm assuming you used the service menu 2pt to correct that?

DV specifically was giving a green cast but not any other uncalibrated HDR mode?

I personally used HDR10 patterns in both HDR10 and converted to DV to adjust my 2pt, focusing on improving DV and HDR Game equally since I couldn't calibrate those modes. But the DV conversion on my player, although not accurate, was at least useful for this since I didn't change luminance in any way, just RGB balance.

Yes, SM 2 pt correction. In my set every mode, SDR, HDR and DV were initially green. I corrected DV by eye at first but now I have some metered data too to calm my nerves :D

No Dolby Digital output; only PCM
 
I cannot get a streaming device to output Dolby Digital. I've tried both an Amazon Firestick and Roku player that I know can output Dolby Digital. I've tried various HDMI inputs to no avail. I've had this issue for a while but just realized something that may resolve it. For example, I have it connected to HDMI4 but see that it still shows "Samsung SMT-H4372, Digital STB" as Connected Device. I actually have the Amazon FireTV stick hooked up. I've tried removing from launcher and setting up universal control but nothing I've done seems to change the Connected Device. I'm thinking that because it incorrectly identifies the device that it won't pass along the Dolby Digital signal that I have properly set on the Amazon FireTV stick.


Any ideas?


Thank you.

Hello. I recently noticed that my tv no longer achieve true blacks. Black bars and even whole screen with black photo looks like dark grey with red tint. It is more visible around edges. I am running 5.30.60 firmware, using sony x700 an blu-ray player and run it through denon x1300w. My main video mode is isf bright with OLED 100, gamma 2.4 and brightness lowered to 48. Lowering brightness even more do not reduce this glow which frankly freaks me out. I am not sure since when this problem exists but i suspect that it started after last update. I don't own harmony remote or phone with ir blaster. Is there something that i could try do on my own? Like should i try use factory reset option on my tv or something? Should i try reflash firmware, is it even possible?

I'm assuming you have a B6. This is common with all 5.x firmwares with the B6.

E6 issues with 4K HDR files
 
I got an E6 and recently started playing 4K HDR files on my Dune Media Player

Some, like Dunkirk and Captain Marvel look perfect

For Jurassic World. The HDR dramatically highlights the film grain. Is there anyway to eliminate this? Or for some movies is non-HDR better because it doesn’t contrast with the film grain.

With TV shows, I get the famous LG motion issues, and all my options are grayed out so I can’t even make adjustments
Anyone to re-enable these options when the Tv locks them out?

Edit: I deleted the squished part because I found out one of my kids hit the zoom button on the media player

morphinapg 06-22-2019 07:05 PM

I wasn't that impressed by Dunkirk. Like the other Nolan 4K movies it had raised black levels

Ugh. When I got my B6 in 2016, I don't remember if it didn't yet have Dolby Vision enable, or that I didn't have any Dolby Vision content yet, but in any case, ChadB didn't calibrate that mode when he was here.

I didn't realize that the Last Jedi was Dolby Vision and I just put it on..., my first DV movie. It's horrid. I tried setting it to the same settings has HDR but it's terrible. Unless I want to have this mode calibrated, which I don't, I suppose I'll just have to mess with it until it's acceptable.

Anyone have any DV settings that they're happy with?

DV should have OLED Light at 50. Turn off any artificial enhancements like TruMotion, dynamic contrast, etc, but leave the rest of the settings alone, except maybe brightness which I set to 49. DV's Dark mode is the more "correct" version.

That being said I've heard The Last Jedi's DV isn't great.

Thanks for the quick response! Good to know about the OLED light because I immediately set it to 100 to match the HDR settings.

Thanks again!

Yeah I feel like a lot of us did that, but I tested and confirmed 50 gave the optimal image. OLED Light actually affects the tonemapping algorithm in DV, rather than working the same way as in other picture modes, so 50 doesn't limit peak highlight brightness. In fact, 100 does make the brightest highlights darker, even though the rest of the image is brighter, because the DV tonemapping appears to take into account ABL, which becomes much more aggressive at brighter APLs.

What brightness setting do you advise for HDR Standard?

With 51 I still get perfect blacks with a 100% black slide in a perfectly dark room. At 52 I don't. 50 clips more near black levels. When movies are graded properly, it looks great. When movies have raised blacks baked in, then sure 50 would have looked better, but sometimes in those cases you see raised blacks even all the way down to 48.

OLED Light 100
Contrast 100
Brightness 51
Sharpness 0
Color 53
Tint R2
Color Gamut Extended
Black level Low

All artificial enhancements off

Greyscale, Color+Gamut, and Tint are all calibrated as well

He has a C6, according to his post in the C6 thread on the UK AV forum.

Seen a few posts now of people mentioning similar with latest firmwares on the C6.

the prices are very similar on OLED as it was 3 years ago on 65, there are minor improvements like Atmos support, the prices are much more down on LED side, FALD sets for 75 inches are under 3K, i paid $3500 for JS9000 65 inch Samsung which is edgelit.
DV support are on LG and SONY Tvs. Samsung on HDR10 Plus.
the upgrade onLED sides is worth on larger size. there are more marketing gimmicks than any worthwhile upgrade to PQ. Better content is what we are looking from Netflix and amazon Prime.
