    LCD are not prone to burn in at all. They can suffer image persistence if left displaying a static image for a long time but it's entirety reversible.

    Yes, OLED TVs *can* have burn in. Yes, Plasma TVs *can* have burn in.

    In normal use however, it's very, very, very, very unlikely to happen. Most people don't sit and watch 24/7 news channels like CNN/Sky news for 5 hours straight every day at max brightness, and unless you are doing that you simply won't have a problem.

    Channel idents/logos used to be a major issue but that itself is very rare these days with most being faded enough to be a non issue, or moving around the screen enough to again, prevent an issue.

    The benefits of OLED over LCD are so great that once you have had one for a while, you will never want to go back to LCD...they instantly look inferior with any dark scenes, and its such a huge difference.

    You wouldn't want an OLED for mounting in an office as a reception TV, or in a shop as an advertising screen or anywhere that will sit and display static content for a long time - but for home use? There really isn't an issue if you apply common sense.

    Agree however you must remember the demographic on this forum is.... nerds. We'll be asking salesmen "does this OLED TV use a pentile array" where the average consumer will be wondering what fresh magic pixie hell this "OLED" stuff is but ooh it does look pretty. Customer education is paramount for this kind of product to ensure that the layperson who isn't a nerd or whose expertise lay elsewhere doesn't make a bad purchase. As you say, it's all about the application of common sense but you must have the underpinning knowledge and I think the companies should, in the knowledge of the relative pros and cons of their products, should ensure this information is available.

    I think that's kind of the point though - the majority of people won't be sat there with news on 24/7 or similar static content. I don't have evidence to back that up, but that would be my expectation and I think it's a reasonable assumption. The specialist community should also have the knowledge to see through the article and understand that the tests performed in no-way represent normal TV viewing and simply show that its possible to product burn in on an OLED TV. Great, we knew that already....

    I have read a lot about burn in on the web in general (notably on AVForums) and am yet to come across an example of OLED burn in with normal/average viewing patterns. Loads of example of people who have left sky on for 2 weeks whilst on holiday (where they purposely disabled the screen saver and other options meant to limit any burn in......), or pub owners complaining that they have burn in from the score box in the top left etc. That's hardly scientific though

    The specialist community is more likely to have problems with this sort of tech as their use case may be different - but I am 100% certain that for the average consumer, who just uses a TV for gaming and watching general TV, will not have a problem with burn-in.

    To LG's credit (can't speak for Sony et al but assume they do the same), they do clearly state the risks of burn-in as part of the manual and setup process, and warn you not to leave static images/channel logos/banners on screen for long periods. Not that anyone really reads manuals anymore but they do warn you of it.

    Re: LG OLED TV test shows burn-in after just 4,000 hours

    BTW my comments about burn-in are predominantly about their use in phones, where they'll be displaying static content a lot of the time. It's something I've experienced first hand multiple times so it's not just a 'in theory this could happen if you did x, y, z' paranoia comment. It's very obvious on display model phones, which to be fair are operated on a much greater duty cycle than a typical phone would be, but many still develop severe burn within a few weeks of release date, and that sort of total usage isn't that high unless you cycle phones every few months.

    I'm open to checking out different models, but like I say my personal experience to date is enough to avoid them where reasonable. And I don't see any compelling reason to not stick with LCD given OLED's drawbacks.

    As for TVs. Not sure I see a major advantage over a decent LCD anyway TBH...

    And some Pentile arrays are pretty rubbish in terms of image quality for a given resolution (objective not subjective BTW). That horrid grainy look. (Not strictly grainy but can't think of a better way to describe it).

    Totally agree on phones as static content is much more common..I can see it being an issue.

    The big advantage with TVs is the black levels and colour quality, as well as lower power usage and generally a smaller footprint (as there is no backlight). I spent a LOT of time looking at this last year when I wanted a new TV and compared the top models from Samsung & LG. I used a scene from "passengers" (dark, spacey, sci-fi, UHD) and the opening of "pushing daisy's" (bright, colourful, 720p) as source material and although not a scientific test...the LG just stood out with the best picture of the lot. Sure the Samsung was brighter in the pushing daisy scene, but it lost SO much detail in the dark ...really was night and day.

    The LG was £800 cheaper too as unlike Samsung, the majority of their range is identical save for appearance and the presence or lack of speakers (and who on earth wants speakers in a top end TV? madness) so it was an absolute no brainer. I should clarify that of course what I personally liked of the picture and the huge perceived quality gap is just my view, but it was a huge difference and I don't think I could go back now. A bit like when you switch from tea bags to loose leaf - you wonder why you ever used a bag

    Current LCD tech will always suffer from it's backlight that means a true black is very, very hard to achieve, and uniformity is currently an issue.

    That's because when Pioneer was making plasma TVs, they were the best of the best. Cream of the crop. Money could not buy better than a Pioneer plasma TV. They were the absolute gold standard. Pioneer used to be a hugely desired name for audio and plasma.

    There's a reason your friend's old 43" plasma TV cost between $10,000-15,000 new.

    Thats why you buy 400£ TV, and not 2000£ one.

    I suspect you may notice the difference in picture quality between a 400 quid 65” panel and a £2k OLED 65” panel.

    A friend of mine has an LG OLED TV and the picture quality is outstanding - the dynamic range of the OLED display is higher than conventional panels and makes full advantage of HDR - to the extent that you do get a real and subtle 3D effect.

    Well, if you are going to leave your OLED TV on, showing a static image continuously for 166 days and 16 hours, then you have a problem...

    You don't have to, the burn-in is cumulative and doesn't have to be in one long run. Unlike LCD persistence, showing different images for a while in-between doesn't really help either.

    Re: LG OLED TV test shows burn-in after just 4,000 hours

    Anyone with an OLED TV care to comment on the brightness settings they use? I've always assumed that one of the advantages of the OLED black levels is that you don't need to whack the brightness up to migraine inducing levels in order to achieve a great dynamic range. I guess in a bright room it might be necessary...?

    Well Samsung are providing a 10 year burn warranty on the TVs, most reputable places provide a 5yr warranty.

    What more does one need to pick a TV up?

    Re: LG OLED TV test shows burn-in after just 4,000 hours

    I've never wanted OLED since I noticed burn in on Samsung Galaxy phones in Samsung retail stores where they keep their display sets at max brightness/saturation/contrast to entice consumers.

    I find a top quality LCD panel is often close enough in image quality (whether it be TVs or smartphones) so I can use it without care about longevity. I place my phone next to my laptop as a constantly switched on 2nd mini screen showing news websites/shows. OLEDs would be burnt in within weeks.
