What does pos mean? Person of...strength? Just stop, dude. I'm done with you. No need to reply. Let's end it now, and let the thread get back on track.
That was a typo. Sorry. I was typing another sentence and forgot to delete it. I just noticed that. Apologies, though I dont agree with anything u said.

Also to make it clear, this guy I meant was not u but the guy who posted in rtings about the subtitle issue . I wanted to say that he might have posted on rtings just to get his attention to lg so that he can get his tv fixed by them even if he himself got it from playing some other static content. I have played that game with another company and they replaced my dac in the past. I ranted about an issue on headfi and where the company officials were part of the thread. I got it replaced in time because of this.


Then I thought it wont be relevant to say. But now that I made a mistake I think I must clear that off.sorry once again for that confusing thing. I have nothing against u.

Thanks for the clarification. No harm done.

Anyway, the guy posted images of color slides of his set. Burn-in is just uneven wear of pixels. You can have burn-in even if the content is moving, but if the high brightness areas fall in the same area. TV sets running demos have had burn-in, uneven wear, pixels that can no longer get bright enough compared to the other pixels, even though the demos are constantly moving. Some people have had burn-in from Rocket League too, because the car is always in the center, even if it's moving. In the Rtings burn-in test, the area where the head of the newsreader would usually be, right in the center, has worn out more too in the news only set.

Burn-in doesn't happen only with static images. It's just uneven wear. Subtitles at peak white setting will burn some pixels in that area. It probably doesn't happen a lot as most reports come from US and UK forums, which are English speaking countries and they'll use subtitles only for foreign language. For some of us, those who watch a lot of English content, subtitles might cause an issue. Even though I have a score of 9 in IELTS in listening, and reading too, I still keep them on because during casual viewing the accent causes me to miss a word or two.

Hi All,
In the recent days I'm experiencing short power cuts in my area during night time when my 55C8 is running. Mostly the power gets restored within 5 minutes....Will it be safe to connect the TV to a inverter line or can I connect it to a 1KV UPS which i use it for my projector?. I'm planning to only connect the TV for power backup and not the Airtel box else my parents will not realize that there's a power cut and will keep watching the TV... please suggest...

Hi All, can you please share your suggestions..

Yes, you can connect it to the inverter line or the ups whichever can take the load. Better to connect it to inverter if it is pure sinewave one, otherwise any will do. Most likely the ups won’t be pure sinewave I suppose.

Thanks for your feedback... The UPS might not be pure Sinewave but will this be applicable only when it turns to battery mode during powercut or will it be a non- sinewave even when running in main power?.

In case if it runs as non-sinewave only during battery mode will this affect the TV if we just require few seconds to manually switch off the TV during power cut?...

When on mains the ups provides sinewave, on battery it doesn’t.
It should not affect the tv as such in the backups short time span more than the abrupt shutdown.

Another problem that I see with turning off the OLED after a power cut while on backup is, incase the 4 hourly pixel refresher starts it is not good to interrupt it. (Vincent explicitly mentioned the same on HDTVtest recently)
So if the pixel refresh starts shutdown the tv only after 8 mins on standby.


I used to power my projector using an apc and it ran fine,also ran a samsung 40” led tv for 2-3 years on ups and have heard a lot of other people as well using ups for projectors and tv’s, never heard of any problems. Don’t know how sensitive OLED’s are.

Anyone who can do a test for me on their LG sets via Hotstar? How much macroblocking, posterization and artifacting do you see on the third episode of GoT season 8; The Long Night? Even 5 minutes of viewing, from the time the red lady arrives and then dothraki start their attack and die will do.

Also, I have taken macro shots of the Metz 55S9A TV, and it is a 2019 panel, with even bigger red sub-pixel than 2018. Blue one is now slightly smaller.
