      hi

      Just about to buy an LG 56 oled and have been researching like mad as am clueless!!

      On the owners thread there’s talk of it but don’t have time to read it all!

      Should this put me off buying oled? (Family tv for home use)

      Thanks

      A 56 OLED? I don't recognise the model.

      Don't worry about QC issues, you can always send the TV back if it's faulty.

      Had 10 LG panels.

      2 were acceptable but not completely free from banding.

      Odds are 1 in 5 imo and that is a qualified opinion.

      Lots of returns. If youre very picky, my advice is to avoid oled. For now.

      This had (has) been my biggest concern in purchasing my oled TV...£2000+ is a lot of money to spend on a TV for most people, and the thought of getting one that is simply unwatchable, and having to return it for a replacement (maybe multiple times) is just so offputting!

      Especially as some companies are (generally) OK with it, to a certain extent, but some seem not too keen on the idea of returning it for a replacement, because of screen quality issues...

      I bought my LG 65 C7 from Currys, and it arrived on Sunday, but will only be getting the chance to unbox it this evening...

      I really, really hope I have a decent set...if it turns out to be a duffer (and the odds quoted above don’t sound good), I might be tempted just to return it for a refund...

      Fingers crossed! ;)

      I have had 7 models in the past 2 years returned and the 65b7 I have now is golden, uniformity is close to perfect.
      Obviously when the newer models come out this will likely be going back though depending if the new features are worth the upgrade ;)

      My first one is the one I kept. What does that do for your odds?

      Go looking for faults and you will find one in every panel.

      I'd be more worried about damage from the 8 month old than anything from the LG factory.

      This is a forum for the very pickiest so if you're not someone after perfection you should take everything here with several grains of salt.

      I've recently got a LG 55C7. The first thing i did was just watch normal content. Didn't see anything amiss so thought i had a good one.
      The next day i did the torture tests to see exactly if it was a good panel or not.
      To my surprise, i have a medium panel. It has three faint yellow/blue tints going across the screen seen on a pure white pattern.
      On the 5% IRE pattern i have one/two slight vertical band and a few minor vertical streaks/bands. (not checked since day one and before any standby image/pixel scrubbing)

      So you would think it's going back right?
      Wrong, i'm very happy with it!

      After testing, I went back and had a full session watching everything and anything. It still blew me away, and i have never seen an image like it.
      I accept now and again i might see the (minor) defects. But as long as that's all they a restricted too, then fine. We on this forum stop watching the content and start just watching the "image". So any minor fault will bee seen. I chose to find the defects first, so nothing would pop up later. That way i can now relax and enjoy the content. (fingers crossed, still not seen anything in normal content)

      I know which areas it could be better (as some people have better panels than mine), but i accept that right now there is nothing else out there to touch the stunning (stunning!!!) image the rest of the time.

      Please understand, i know some people are not being fussy. Some of the pictures posted are obviously faulty panels, and ARE unacceptable. And those people have every right to a replacement/refund.

      £1500, £2000 or £3000.

      It's an awful lot of money for a technology that's not yet able to produce an image free of vertical banding in low light shots or on occasion football.

      The technology needs to mature a few more years yet.

      My money is going on a quality and proven led next.

      @Paul D I don't suppose you could let me know how I would do a similar test to check out the screen quality of my new 65 C7 could you?

      Like you, I am hopeful that even if I have a "medium" screen, the quality will be so good, that most (probably over 95%) of the time, I won't even see anything...but I do like your thinking about finding out where the problem areas are right at the start, so that there won't be any nasty surprises later in the TVs life...and I can get on and enjoy it, and not worry about the image...

      Thanks,
      Kevin

      Funny if it wasn’t that I won’t trust anyone who has had 10 panels I’d invite you to come and take a look. Nothing wrong with it.

      Just google "5 ire test pattern" on the TV's web browser. Select "images from the results, then scroll down to you find the right one (a very dark grey image with a 5% badge bottom left). Then select view image, then full screen.(make sure your not viewing somebody else's 5% screen shot!)
      That will show any vertical banding. It will change once the panel has done a few standby pixel scrubs.

      I then googled "TV test patterns". Plenty of RGB/colour full patterns. A yellow pattern will show tinting/blue tinge.

      I watched some films mentioned on here that show low grey/shadow detail problems.

      Lastly i watched some demo snow/sand scenes. Youtube/web/Dolby demo in apps.

      Every LCD I've bought has been a lottery, took about 3 to get my old one, the one before was about the 3rd attempt too. With the OLED, I accepted the first one although it wasn't 100% but much closer to perfection than any old LCD, you just accepted more issues before. Unfortunately I had to send it back to get the cheaper price, now waiting for a voucher to arrive before I can order again (I am scared)

      I would say it's less of lottery with OLED from experience - but a lottery never the less.

      Not necessarily. Maybe you're too picky. I also have an E6, I kept the first one I had. I am very critical. However, I never put on any grey slides or went looking for banding. Instead I looked at how the TV performed when I used it as I intended to do for the duration of it's life, and I saw no issues. Several months in curiosity got the better of me. Did I have a perfect panel or did banding on grey slides have no effect on my actual use in most cases? Well, I saw some banding that would have probably made me consider returning this TV if I'd checked in the first few weeks, but I'm so pleased I didn't because I absolutely cannot see this in normal viewing and the picture quality now it's been calibrated has to be seen to be believed.

      All I'm saying is that I think people get too hung up on screen uniformity in conditions that are simply not realistically going to present themselves in normal viewing.

      DB9506 clearly has something against these.

      If you go looking for an issue you will find it. That's the problem with using test patterns to see exactly how good a screen is, checking for banding thoroughly etc.

      Just get the TV home, set it up and turn it on and watch it. If you are happy then good.
      There are a lot of threads on AVF about this, it seems people go looking for issues rather than just being satisfied with it.

      Now I'm not saying the TVs are perfect, clearly there are some very bad examples where you will clearly see issues as soon as you turn it on, but the majority are perfectly fine.

      For reference this is a 5% screenshot of my E6, like I said the first one I got home. I actually don't know if this is deemed good by banding critics, all I can say is I don't see these bands in any viewing.

      My OLED is great under normal conditions, best tv I’ve ever owned, it might have issues if I go looking for them, but if they don’t show up under normal conditions they effectively don’t exist as far as I’m concerned.

      There is no such thing as a 100% perfect panel look hard enough and you’ll find something.

      That's right. 99.9% of panels are fine. constantly returning tv's because of some minor issue discovered on an obscure test pattern that nobody cares about , and isn't noticeable in normal viewing content unless you press your nose to the screen is......daft. stop it. thankyou.

      For what it's worth, my opinion is that 55inch have very few issues than 65inchers so get that OLED and you will be happy!

      Often it is VERY VISIBLE in normal dark scenes or dark movies. So you can see it allot.

      However 55inch screens typically have better screen uniformity on LG OLED’s vs 65 inch models. Close Viewing distance and low room light viewing can really show off the terrible banding.

      My 12.9 inch LCD Tablet has perfect screen uniformity to me, why can’t a £2000+ OLED be as good.
