You can downgrade on a B6 with FW 5.40.03.
Using Sure app?

The word "yet" in that question doesn't belong. It's like asking "Any news on the sky turning black during the day and blue during the night yet?"

Not sure. But people have been successful using this method https://github.com/joey-astrologo/OL...ster/README.md

It only works on 5.40.03 apparently and you need to have the correct region file of the firmware you want to downgrade with on your computer for it to work.

I discovered that there are two programming systems USA and Korea use ATSC however we in Europe have DVB. Unfortunately i did not know that and installed ATSC version on my European C8 unit. That’s probably the reason why i cannot programme any programmes via antenna. What’s more even that there is higher firmware version the system does not see it as I am on ATSC trying to install DVB. If i copy ATSC new firmware version on pendrive TV recognizes it.

That’s how American software file looks like
starfish-atsc-secured-o18-56.glacier.o18-5624-05.10.20_prodkey_usb_V3_SECURED.epk
and below European one
starfish-dvb-secured-o18-56.glacier.o18-5624-05.10.20_prodkey_usb_V3_SECURED.epk

Firmware downgrade function is still not working, as I was able to change my DVB software from 04.10.55 firmware to ATSC 05.10.03 I believe if it was available I could return to DVB firmware. Maybe is there any other way to change tuner setting in service menu? Really appreciate your help because I don’t see any available solution for my case, unless there will be firmware downgrade available again but who know if it will work.
That sucks. You could tell LG about this and they'll send a technician out to you. From what I know, LG technicians can still access the manual software update feature that LG blocked in the newest firmware.

I will say that I used my calibrated C8 settings on my E8 and the bright room SDR looked great but the dark room settings we're awful and killed any detail in movies so I used the bright room settings on my dark room and just lowered the panel brightness and it was amazing. Every panel is different and that showed with me trying my calibrated C8 settings on my E8 but the settings should be a decent starting point regardless. Find a dark movie and compare. I used I am mother on Netflix and looked at many scenes but it definitely dialed my settings in perfectly for me, well good enough for a bedroom TV that is.

So did 5.10.20 go OTA in North America last night?

I came home this morning and noticed my audio settings were on something other than HDMI ARC and I was getting ready to cuss someone out for messing with my TV, then saw the firmware updated at some point.

Hmmm. Firmware upgrades don't/shouldn't change any high level settings. My update to that version certainly didn't.

Nobody has an answer to my question?

I added another picture - Biden's hand from democratic debate.

Samsung VS Oled + Biden's hand

It just seems like some parts of the screen have different color. Like Jacket - left side is different than right side (samsung doesn't have this issue playing the same video). Now Biden's hands - left one is dark grey while the right one is normal.

What's wrong with these colors? May be it is burn-in, but I don't see these areas affected when I play youtube burn-in test video with solid colors .

Thanks.

Your best bet is to talk work LG. I don't think anyone can really tell what's going on witout being there.

Have you tried running the pixel refresher? Resetting tv? Soft reset ( unplug for 10 minutes)

You said that you're using Rtings settings. Does that include CMS and White Balance RGB adjustments? They did some significant changes there and using such settings could be totally wrong for your panel. You should never blindly copy settings from another calibration.

Did you try with one of the accurate picture presets at default settings?

Subtitles burn-in

Hey guys, i am about to return my C8 after watching this video:
(look at 7 minutes for the subtitle burnin)

English is not my first language and i watch all movies and series with subtitles, originally i was not worried because i owned a Plasma for 5 years with no problems, but now learning that differently from Plasmas, OLED burn-ins are cumulative, and that subtitles can cause a pretty serious burn-in i see no other option but to return it and get a LCD TV.

Please let me know your thoughts about this, is there any reason to believe that C8s are immune to this comparing to the C7?

By my calculations i will reach 7000 hours on my TV in less than 2 years, and that picture in the video showing burn-in subtitles is from a tv with 7000 hours on it.

^^ How does 7000 hours of watching TV relate to burn-in for all OLED TVs and its viewers?

I am pretty sure that 7000 hours of normal use will not burn-in any OLEDs, but i highly doubt most people here use subtitles in 90% of those 7000 hours like i do, that is what worries me.

IF you have subtitles on 90% of the time, and IF you get some burn-in after some period of time, then 90% of the time you won't notice the burn in because you will have subtitles showing anyway.
Some players allow you to adjust the position of subtitles, the density or color, etc.

Just don't use bright colored subtitles, especially not yellow. That's the worst you can do and from the looks of it is what the user in the rtings video did. Best would be gray semi-transparent.

Yep sounds about right, but that is not an option for me since many channels i watch have embedded yellow subtitles

I'm off to adjust my options now

Unfortunately, Netflix only offers choices of fully saturated black/white/red/green/blue/cyan/magenta/yellow. No greys.
Amazon Video offers presets of white or yellow.

I currently don't have a netflix subscription, so I can't check but I'm sure I could make the subtitles white semi-transparent which is just as good or even better than gray.

I really don't think it will be a problem, and you are reacting too soon. You might get image retention, but full permanent burn-in is different and rare. There are simple precaution you can take. Just like you wouldn't cross the road without looking, be sensible with your settings.

Don't use Vivid mode. Use ISF Dark/Light or Cinema.
Don't crank up the OLED Light value to stupid values. It's on 25 (giving 100 nits) in Technicolor mode for a reason. So 30-40 max should be the normal range.
Use the Screen shift, and Logo Luminance Adjustment features.
Use General Eco Mode timers to turn the TV off automatically if it's left on by accident.
Put the TV into standby with power when not in use and let it do its compensation cycles.

If there was a real fundamental problem then it would be world-wide and widely known about; many countries watch subtitled content a lot (Hollywood is a bit popular in many non-English speaking countries for a start!).

At the end of the day it's something you can judge the risk on. It's ok to be cautious but perhaps you are jumping the gun by reacting to the R-Tings video, instead of what happens to your TV with your usage.

Just an fyi, you should never use someone else's settings on your panel. You can make things worse.

Every panel is different and calibrations are done for that specific panel.

Ah yes you're right! Thanks!
There are 3 font sizes.
Font colour (foreground) is WBRGBCMY, with a "semi-transparent" tick box.
Background is WBRGBCMY, with a "semi-transparent" tick box.
There's another option for "window", which is a "background of the background" spanning a wider width.

How I missed the semi-trans tick box just now is beyond me

His set must have had an amazing amount of black crush. These put the “firmware era” black crush adjustments to shame. I wouldn’t even try these settings myself as I know they would look washed out. Gamma needs the proper tools to measure correctly.

Don't use Vivid mode. Use ISF Dark/Light or Cinema.
Don't crank up the OLED Light value to stupid values. It's on 25 (giving 100 nits) in Technicolor mode for a reason. So 30-40 max should be the normal range.
Use the Screen shift, and Logo Luminance Adjustment features.
Use General Eco Mode timers to turn the TV off automatically if it's left on by accident.
Put the TV into standby with power when not in use and let it do its compensation cycles.

If there was a real fundamental problem then it would be world-wide and widely known about; many countries watch subtitled content a lot (Hollywood is a bit popular in many non-English speaking countries for a start!).

At the end of the day it's something you can judge the risk on. It's ok to be cautious but perhaps you are jumping the gun by reacting to the R-Tings video, instead of what happens to your TV with your usage.
Yep i agree that it is probably ok, but if someone got permanent burn in with subtitles i will most likely get it since i use them all the time. I was also reading about this guy who got a netflix logo burn just by browsing the content and choosing shows.

I don't know, everybody told me that burn-in risk was a thing of the past for OLEDs, but it just don't seem like that is the case...

Burn in is rare with regular TV use.

Subtitles may be an issue but there are ways to minimize it as posted earlier.

As for the Netflix logo burn in while browsing titles, highly unlikely unless that's all he did on that tv 10 hours a day. Also his picture settings could of also led to an issue. In this case it may have been more of a temporary image retention then burn in.

Every panel is different and calibrations are done for that specific panel.

Why never? As if, if you try you cannot reset or change it anymore There is no harm in trying and see. You won't know if it will make it better or worse until you try it. We know that every panel is different but you can always reset it if you don't like the result. I used chronitis settings and mine looks great to my eyes.
