All OLED TVs are susceptible to burn-in due to the nature of the panel itself, so I'm not sure what exactly you mean by "resolved". There are multiple features in place to mitigate burn-in issues. Most of what you're going to see is temporary image retention before a permanent burn-in, anyways. More info from LG: https://www.lg.com/us/experience-tvs/oled-tv/reliability and from rtings: https://www.rtings.com/tv/learn/real-life-oled-burn-in-test If you watch varied content and don't leave the news on the entire day, you'll be fine.
Wrong! My 2017 OLED LG suffered burn in from watching CNN or Fox business 3-4 hours a day. The screen logos became permanent after 6 months.
My 2017 OLED LG started suffering from burn-in less than a year into its life. It's now got significant burn-in across various parts of the screen. The only static images that were on the TV for any extended period of time were the included screen savers which I don't believe could be the culprit. I think I just got a bad panel, or maybe some other factor contributed to the problem such as dirty power or something. In looking at the research, it's obvious that my problem is not normal. But it's proof that burn-in can wreck an OLED panel fairly quickly through regular use, and such damage is not covered under warranty. It's just an added risk you only get with OLED. For what it's worth, being that I've never seen anyone else experience anything like the problems I've had, I'm assuming it's pretty rare and getting a new LG to replace the current one.
The 2020 CX and GX models have anti burn-in features. Specifically, the TV will detect static parts of an image likely to cause burn-in by monitoring them for 2 minutes. If they remain unchanged for that time, the tv will reduce the brightness of specifically those static pixels by 20% over the course of 90 seconds, which reduces the chance of burn-in so far as to be infinitesimally small. In addition, the TV will run maintenance and diagnostics on its pixels when it sits on standby for long enough as well. All of this is beyond the fact that most use-cases for this TV run no risk of burn in by default. Only static pixels, like a logo for a news channel or a static HUD in a game run the risk of burn-in, and that risk only becomes measurable when the news channel or game is displayed on the TV for hours and hours daily for months. Unless you're an 8 hour a day gamer, or planning to use it as a computer monitor that you keep on 10+ hours a day, you run practically no risk of burn-in.
Burn-in and image retention are possible on virtually any display. It is rare for an average TV consumer to create an environment that could result in burn-in. Most cases of burn-in in televisions is a result of static images or on-screen elements displaying on the screen uninterrupted for many hours or days at a time – with brightness typically at peak levels. So, it is possible to create image retention in almost any display if one really tries hard enough. And even if image retention does occur from extreme usage, it can usually be mitigated within a short period of time by turning the display off for a while, and watching a few hours of varying content (such as your standard TV watching and channel-surfing). OLED TVs have special features and settings to preserve image quality and prevent burn in and image retention. First, under OLED Screen Saver there is the Pixel Refresher that calibrates any issues that may arise on the screen when your TV has been turned on for a long time. Calibration takes more than an hour. The second feature that can be employed is the Screen Shift feature which, moves the screen slightly at regular intervals to preserve image quality. A third option is the Logo Luminance Adjustment, which can detect static logos on the screen and reduce brightness to help decrease permanent image retention. ^Daphane
My 2017 C series OLED panel has just been replaced because of this problem. I asked the guy from the service and according to his experience with TV's 2020 models and newer ones have this issue solved. Of course every TV can be quickly damaged by displaying static content but he said - the newer matrix controlling module handles logos and information strips pretty easily.
