4.10.65 just came out today 5/3 right? I swear last night the B8 firmware page said 4.10.55 with the same date of 4/27/2019.

I downloaded it to my flash drive a few days ago. It is the .65 version. Been chicken to install it. Don't want to be the guinea pig.

I searched on my 55" B8 for updates yesterday and it said no available updates. I have 04.10.15.

Never signs up for anything

Hi all.

I own oled 65 b8 and soundbar Samsung hw k950.
When I play Atmos or 5.1 movies with shield tv everything sounds great and ALL speakers are active.
When I play 5.1 movies with Netflix or Prime Video app no problem (over hdmi arc)
When I see a movie by sat or tv channel, even if movies are Dolby audio 5.1, I can ear only STEREO sound, with rear speakers completely inactive.
Can you help me?
Thank you.

Angry Standby power issue

I just bought a new LG 65" B8 - and couldn't be happier, except for 1 problem. When I turn off the TV with the remote, it is still drawing over 50 watts.

Several options in settings, such as "Quick Start", say they increase power consumption. I have these turned off, but I don't think they do anything. The TV still starts up without delay, it is as "Quick Start" is still turned on but shows as off in the settings menu.

This is a major annoyance as I don't watch enough TV to justify a 24/7 power draw, so I end up having to unplug the TV when I am done watching.

If you have been watching for a few hours, make sure you don't check the standby power until 10 or 15 minutes after turning it off. It does a screen clearing every 4 hours of use which takes something like 8 or 10 minutes when you turn it off. After that it goes into proper standby. Turning it off before it can do that screen clearing will make it have problems, so definitely do not unplug it before it has had time to do that.

I've left it hooked up to the meter and observed it periodically over a few hours - it does vary a little, but has a constant draw around 65 watts, never below 50 watts.

This is even worse - what a pain! Now I have to wait 10 minutes and remember to unplug it.

That's scary, you made me to borrow one to check mine, I'll report back if I receive it. Has anyone else tested this?

The new firmware update was available this morning. My TV asked if I wanted to update, so I did. 4.10.65. Not sure what is in the update though.

I just got my b8 Saturday. Loving it so far.

Looks like B8 has the gamma problems from the C8-W8 too. I just installed the brand new .65 firmware and ran a black clipping test and instead of 17-25 only the bars 21-25 were flashing. I am using gamma 2.2. When I changed it to 1.9 everything seemed normal and 17-25 were flashing again.


Unfortunately I can't say if .65 introduced this or .36 already did. The last time I ran the black clipping and adjusted my brightness a little bit was at fimware .20 but haven't checked in .36

Same behavior on my B8 as Franconian described. Black levels are significantly worse on .65 compared to .36, but i don't know if there is a difference between .36 and previous firmware version since my B8 is only 3 weeks old and came with .36.

On .36 with gamma 2.2 and IRE 5 set to 10-15, everything above 17 black level was visible, but now, on .65 i can't get them to show unless i switch to gamma 1.9. No idea why i updated...

I've seen that the discussion in the C8-W8 thread is much more extensive, and as i understand there is a gamma fix firmware in testing - is this info reliable? And is there anyway to find out is a similar fix will be available for B8? (i contacted LG support but that's useless)

As some people have mentioned, firmwares are first available on C8-W8 and then on B8 due to alpha 9 - alpha 7 cpu.

In my experience LG is pretty bad at supporting older products, maybe we'll get stuck without a fix especially now that 9 series is out? I don't really want to downgrade my firmware...not sure how safe it is and also i have no idea where i could get and older version.

I can still return my B8 but i would prefer not to, because otherwise it's amazing, gray uniformity is great, no other issues.

So basically, does anyone have any info if the black levels problem will also be fixed on the B8?

So does it really draw 50 watts in standby like the guy above measured?

Thanks for the confirmation! I hope I can get my hands on a .36 Firmware (I deleted mine ) so I can downgrade and compare again.

Maybe the same is here (in PC mode, SDR, ISF dark room, 2.4 gamma), checked with AVSHD bt.709 black clipping mp4 file: 17 and 18 is barely visible and the rest seems to be more brighter than before.
I'll try to put back v04.10.25 to check it again and report back.

I was using ISF dark room, OLED light 40, 2.2 gamma and brightness 54 to achieve a perfect AVSHD black clipping test in a pitch black room (brightness 50 that many use was too dark for my panel, 17 was not flashing). Now with the new firmware I must set the brightness to 60...but I think I will just use 1.9 gamma for just now to get a smoother gamma curve or using that what some C8 guys use:


IRE 5 -> 15
IRE 10 -> 15
IRE 15 -> 13
IRE 20 -> 8
IRE 25 -> 8
IRE 30 -> 6
IRE 35 -> 6
IRE 40 -> 6
IRE 45 -> 5
IRE 50 -> 5
IRE 55 -> 5
IRE 60 -> 5
IRE 65 -> 5
IRE 70 -> 3
IRE 75 -> 3
IRE 80 -> 3
IRE 85 -> 3
IRE 90 -> 0
IRE 95 -> 0
IRE 100 -> 0



Still hoping somebody uploads a older firmware...

You can download v04.10.25 (1 fw older than 36) from LG site, if you are not affected by "AVR Not Supported error".

Hello! If I understood it correctly, on .36 you didn’t adjust the ire, just the brightness? And you didn’t use gamma 2.4 even in a pitch dark room? Thank you

I never touched IRE. I have the B8 since November and I'm running gamma 2.2 from the begining. I just read about the IRE settings in another forum, as a direct measurement for the bad fimwares that bother C8 people since weeks. Some are using those and some are just switching to a higher gamma setting (like 2.2 > 1.9 or 2.4 > 2.2) until LG comes up with a fix

Success!

I just downgraded to 04.10.25 using the .epk and the "Smartify" Remote App for iOS (go to the button App and a window is opening where you can select the epk within the LG_DTV on your USB stick).

My gamma curve is normal again, just like before the 04.10.65 update.

Thank you. I wonder why so many people recommend gamma 2.4/bt1336 for dark rooms..

I think many calibrators and professionals prefer this or that depeding on the room and the device, but with calibration of course, but it looks like 2.2 is mainly used.



I'm used to 2.2 ever since and like it's detailed shadows, while others prefer 2.4 for it's "punchyness", but my TV is not calibrated, I used the Rtings settings with a little tweek here and there (like Warm 1 instead of 2 because it makes the picture white and not yellowish, brightness 54 instead of basic 50, and light 40 because I watch during the day sometimes and 20 is too dark).

Punchiness might also be the reason why factory settings also use 2.4. To impress layman buyers.

Some dark details are surely gone when I move from 2.2 to 2.4.

Hey all

One question about OLEDs.

Do they have black crush and how good are they for shadow detail? Is LED better in this aspect?

How long until ABL gets activated?

Thanks!

Hello!

Someone please help if you can.

A few weeks ago, I got the Panasonic UB820 Blu-ray Player. I had a Sony 4k Bravia TV, and this player helped picture quality immensely, but there were still horrid black levels that were instead grey with light bleeding through.

However, two days ago, I got a fantastic deal on a new LG B8 OLED. The TV's blacks and colors look great!

HOWEVER . . . there is a jitteriness/judder to the video and heavy noise during all or some scenes of movies/videos, particularly while playing 4K discs through this player. The 4k discs played fine through this same Panasonic player on my previous Sony 4K Bravia. But not now.

This is not a defective TV. Best Buy even replaced it and I have a second one and it's doing the same thing. The settings on the TV are currently at recommended from the factory, though I've tried all settings on the TV to see if it would change anything. It did not. I have the proper Pearl 4K HDMI inserted with the arrow going towards the TV.

There IS a curious message about the HDMI Ultra HD Deep Color setting on the TV, stating that using the function could cause video playback issues, but you can't switch it off it on the TV; it forces you to watch with this function on while playing a 4k Blu-ray. If it's a player issue, I don't know what needs to be altered. I do have it set to OLED.

I am not sure what to do about this. Unless it's something on the Blu-ray player or this non-negotiable HDMI Deep Color switch, I am clueless as to what could be causing this.

All I know to do if I don't get answers is to pay someone 100 dollars to come out and troubleshoot, and I'm terrified the person will tell me the blu-ray player and TV aren't compatible. OR, take it back and stick with my crappy TV that at least plays without noise and judder. OR, go up to the C8 and pay more, which I don't want to do.

I am not the most knowledgeable on these matters, but I have a great player and an OLED TV and can't get 4K Discs to play properly on this TV/Blu-Ray player. Someone please help if possible.

Thank you.

As of now they don't, if you use firmware before v04.10.65 on B8.

ABL is instant (you can't switch it off) above a certain brightness, ASBL is more than 1 minute (I don't remember exactly). And there's a 3rd dimming issue (probably a bug?) that's independent of the previous 2 and no one knows what triggers it and it seems completely random.

And there can be also tinting.

It can happen based on your settings. We have to distinguish between judder and stutter: read through these 2 pages and watch those videos as well.
Rephrasing the tagline of After Earth: Stutter is real, Judder is a choice.

Unfortunately I can't say if .65 introduced this or .36 already did. The last time I ran the black clipping and adjusted my brightness a little bit was at fimware .20 but haven't checked in .36

I'll try to put back v04.10.25 to check it again and report back.

My gamma curve is normal again, just like before the 04.10.65 update.
Thank You, @Franconian , I can confirm your findings (in PC mode, SDR, ISF dark room, 2.4 gamma, madvr + 3dlut):
reverting back to v04.10.25 solved the crushed 17-18 levels.

So, the last firmware that doesn't have the "macroblock fix" is v04.10.36 .
What strange about this is LG has put this info into the C8's changelog but not the B8 one.

Don't be scared, it's easy, you don't even have to touch service menus.

How to downgrade / upgrade LG OLED firmware:
  • note: this method only works when you are on v04.10.* firmwares (LG removed this from v05.* ones)
  • prepare a thumb drive with the required firmware
    • download the required firmware zip file from LG site
    • create "LG_DTV" directory in the root directory of the thumb drive
    • extract the zip file and copy the "*.epk" firmware file into the "LG_DTV" directory on the thumb drive
    • plug the thumb drive into the TV and turn the TV on (if it was off)
  • use an app on a mobile via WIFI (!) to trigger the special Firmware update mode in normal TV mode (that also allows downgrading) (no IrDA is required)
  • the above last step triggers the special Firmware update mode on the TV
    • select the extracted firmware file and click the Update button
    • the TV will reboot automatically after a successful firmware flashing

Note: all the settings were untouched (even ASBL is off in IN-START menu) after downgrading from v04.10.65 to v04.10.25 , but probably it's a good idea to Factory reset the TV settings.

Lastly: to prevent the TV always reporting that a newer firmware is available, you can block access to the following domains in your router (if it has an option for this):
lgtvonline.lge.com
snu.lge.com
su.lge.com

Note:
- I'm not sure whether all 3 domains are needed
- app store still can be accessed and apps can be updated

Thanks for replying, Chros73.

I read that but it doesn't really inform me on what to do. Maybe I'm just an idiot though. There is a lot of noise/pixelation on 4k discs. Looks like heavy grain-like noise has been added or magnified.

I figured if I bought such a good TV and high-end blu-ray player that I could finally watch 4K discs as they were meant to be seen. But no, no one knows why this is happening. Five guys at Best Buy don't know, and there advice is to have Geek Squad come out for more money. And no guarantee they know, either.

I think I'm just going to give up, honestly.
