LG OLEDs have a screen burn-in issue after a while, which is unfortunate because other than that they're the best TVs on the market.
My LG C6 from 2016 has had significant screen burn-in issues for a few years now and at this point it gets all kinds of "smearing" on it whenever something is staying in one spot for too long. My mom has it and I can always tell if she's been watching MSNBC or one of those other bullshit networks a lot because their logo/chyron will be faintly visible onscreen.
Was hoping my LG C1 from 2021 wouldn't have the same issue, but as of 3 years in, there's a super-faint outline of things after they're no longer onscreen. Usually just bright white things, like a word in solid bright white might faintly continue to appear for a few seconds after it's no longer onscreen. Generally have to let it sit for a few minutes for this to happen. So game title screens are the main culprit. It's just the beginning of it, but my C6 did the same thing, so I can expect the C1 to start having some burn-in as well.
Just a notice to people. 3 years is a pretty long time to have zero issues so that's cool, but if you're like me and get new TVs every 5-6 years, expect to start seeing some burn-in halfway through the life of an LG OLED. Might only be the C models, I don't know. I've heard G are more sophisticated.
