    It shouldn't have worse gray uniformity/edge bleeding. The screens are all made after the same specs and probably in the same factory by the same machines. I think it's worth getting it replaced as soon as possible, if you're anything like me that stuck pixel is going to bother you to no end.
    30 mins isn't going to fix it, I really recommend you leave it for 24 hours. Do it when you're away from home for a day. But for now at least run it overnight and see if that helps.

    There's probably another 3.5mm jack for the white and red, so you'll need a 3.5mm to 2xRCA adapter if one didn't come with the TV.

    yep !

    i had to use the other optical thingie, the yellow one, i just simply plugged in the red and white onto that and put it into the back of the tv.
    and bam sound + video all good.

    and man, i think i will just keep the tv.
    i will forget about the pixel just as i did on my n3ds xl.

    as long as it don't spread i wont have to worry.
    i am amazed by the picture quality of this tv.

    and it has amazing low input lag , so fast.
    and i got rid of the edge bleeding by just rubbing it gently in circular motion for 20seconds.

    just hoping that it wont come back.
    and well, like i said.

    the other of the same unit i could get replaced might have worse issues.
    so i plan to keep this one and see how it goes, i have warranty on it , so in case something happens to it i might be able to return it.

    i did not ask them whether the warranty also gets me to swap it directly with another unit, but it has 1year warranty.
    and i guess what they would do for me after a couple of months of using, they might not swap but try to 'fix' it i guess.

    i want to keep it for the great picture quality + very low input lag which is so amazing for gaming.

    You are probably right about that last part. With things like stuck pixels it's best to get it replaced right away, since they'll usually replace it for you on the spot. If the TV is a few months old they probably won't want to do that. That's why I recommend to get it replaced ASAP.

    yeah but the next set could just as well have a stuck pixel or 2 or 3...

    and guess what , i just now turned on my 1080p LG lb65v tv and i found it has blooming and i never noticed it up until i closely looked for it XDDD

    and guess what, i found a stuck pixel on it as well looks greenish.
    and it has probably been there for a a year or maybe since i got it 3-4years ago.

    and yes mate, if i want it swapped it has to be within the first 2 weeks.
    i already had 1 swapped 2days ago ,if you read the thread you will know what i mean, i got another model and it was just awful with the blooming , there was just too much on it and dse.

    but the one i have with the pixel stuck issue is quite amazing, and the thing is , i have it already wall mounted and all my cables in and updated the tv and everything is good.
    my worry is the next set could be worse, and the other thing is, i am just tired to do all the work again with the wall mounting/cable management etc.

    lastly for good measure , i just want to ask again, is there a chance of a stuck pixel spreading itself? if not ,then this tv is a keeper for me.
    thx

    @sarkwalvein @The Real Jdbye @DinohScene @SG854

    hey ya guys, had to quote ya'll hope you have some spare time to read this 'little' issue of mine on this very same tv (with the pixel).

    anyways, it is not about the small pixel this time, it is about the clouding /blooming edge bleeding and whatever else they call it.
    it seems LED/LCD tvs all suffer from this fate, some have major clouding etc. some have minor some have in between.

    the set i have now has the in between amount i guess..
    it is only noticeable when i watch a movie OR when i game and there are some dark scenes/loading screens and so on..

    my previous TVs had this too but not the amount of this one has..
    and now i am going OCD about it, there is a Local Dimming feature in this LG set and when set to high it darkens those corners (the right bottom/top corners are the worst with clouding).

    anyways, they have another set at their shop, when i was there some days ago i told them to turn off all the lights (there are hundreds in their shop, so it is hard to see any clouding XD).

    they turned them off for me, i checked the other set of the same tv there, it had a stuck pixel as well (a completely red one?)
    but i think it had abit less clouding, but then again i was thinking "Yo eff it, what if i take this home and then in my dark room setting it all up and then bam it has actually the equal or maybe even more clouding"

    so what i thought of doing atm. is i will try my best to get used to it, because the tv is really exceptional for Gaming as it has a ridiculously low input lag.
    at 15ms according to rtings.

    and plus this tv is not even mine, i bought it for my other brother, but i will be using it for a while, and when i think about my brother he is not OCD at all and he wont notice that clouding unless i pointed it out for him.

    he watches alot of series etc. so i guess i will jus tell him to keep local dimming on in his case.

    as for me , what do you guys think about local dimming ? sometimes it distracts me to be honest and well, i feel like it adds to input lag, so i keep it off.

    i will just use the energy saver option of the tv to darken the tv and make the clouds more bearable.

    (also i tried rubbing it was no help, but i have not tried unscrewing the screws to lessen the pressure on the tv, but the tv is very thin so i do not know if it is a good idea to loosen the screws..)

    I would say bear with the "blooming".

    Regarding technology, due to how LCD works, everything with a backlight (LED, fluorescent or whatever) will have blooming. That include TN, IPS, whatever type of LCD.

    OLED/AMOLED technology doesn't have this problem, so if you are ok selling a kidney or two and you really want to avoid blooming, I guess you could try a quality AMOLED panel.

    Regarding "local dimming", well, I don't really know.
    In the one hand, I know that there are some expensive top tier systems with over 64 zones of independent local dimming, in the other hand my 4K TV set has "one zone", thus you could say its "local" dimming option is more of a global one.
    In this case I hate "local" dimming, as it makes the whole screen go brighter and darker in stupid ways, as e.g., if I am watching a movie with subtitles, every time a subtitle is displayed the whole screen goes brighter to support the high intensity of the subtitle text, it is awful.

    It has some blooming, yeah, but I think my eyes have kind of adapted, because lately I don't notice it unless I try.

    Unfotunately, that's indeed how LCD works yeh.

    OLED is the future, but it significantly loses colour intensity after a year or 2.

    glad to know , when i tested out the lg i was using previously it has blooming too not that much.
    but when i focus on it ,it has some on every corner every edge of the panel.

    so i was like shoot , i never noticed this before XD
    i guess one can get used to it all, i will try getting used to mine.

    (mine for now, and when i can't deal with it , i will tell my bro to bring me the tv he is using atm. a 55' Samsung 1080p 2014 model i believe ,i think it has a decent enough screen and most likely less blooming).

    well, will see how it goes.
    i still owe the LG store 200$.. (which my bro will pay).

    the set cost 1000$ , tvs this expensive should really be perfect, screw all the TV manufacturers, most of them produce tons of shitty ass panels to be honest.
    LG/Sammy/Sony etc.

    Reference displays can be up in the $5,000 US dollars for a 17-inch, to $45,000 for 30-inch, 4K and HDR. So no. A $1,000 one would not be perfect.
    And even the $45,000 one can't cover the full HDR Rec.2020 standard. There are no display's that exist's right now that can.

    https://pro.sony.com/bbsc/ssr/cat-monitors/cat-oledmonitors/

    For SDR you can get a reference display that was sold to consumers for $3,000, the Pioneer Kuro Plasma KRP 500m.

    https://www.ebay.com/itm/Pioneer-Ku...478115&hash=item44067e0944:g:ZGEAAOSw6YtZVIMm

    These are hard to get since they stopped producing plasma's. Volt modifying this display can give you black levels at 0 nits, and give the same infinite contrast OLED's give. Its superior to OLED tech, and since its reference its what all displays try to match including OLED's. So no. Not even for SDR, $1,000 wont get you a good display in a big size, let alone 4K and HDR.

    On my LCD there is clouding, but it goes away when lights are turned on. You can probably set up dim lights for night time viewing.
    And having another light source, other than your TV to light the room, will make viewing your display be easier on you eyes. This is usually the set up for people with non perfect black displays. It makes blacks appear deeper. It'll be kind of like movie theater setup where they have dim lights all around.

    On my display clouding is hardly noticeable.

    I have many LCD's in my house, all with varying black uniformity, but my main one black uniformity is excellent. With no Clouding or Flashlighting issues.
    Compare that to leonmagnus99 display, and you can see a huge difference.

    My display
    https://www.rtings.com/tv/reviews/samsung/h6203

    leon's
    https://www.rtings.com/tv/reviews/lg/sj8500

    So black uniformity isn't a huge limitation on LCD tech.
    LCD's can have great Contrast and Uniformity. Like my particular display has. It really depends on the display you have.
    My display has no local dimming, but I don't really care because blacks and uniformity on my display is good.

    Its not 4K or HDR but I have no use for those right now.
    And for a $500 mid range tv, which is cheaper than other displays on the high end, its picture is pretty good.

    You can also try to massage your display to improve uniformity.
    Or you can loosen your display screw's to fix flashlighting.

    Heres some information on that.

    hey mate, thanks.
    already tried the massage fix.

    it helped a 'bit' there is only a big amount on the right bottom corner, the rest of the screen is not distracting as much.

    as for loosening screws, i tried the ones on the back and it did nothing, and so i think that those screws are only for the cover of the back.

    i would have to loosen the screws of the panel itself after taking off the cover i guess.

    i will only do this though after i am certain that i will indeed 100% be keeping this set.
    for now i will wait until another week or two.

    if it does not get better i might be forced to ask the LG shop to get it fixed for me or replace it (apparently some tvs need to get warm etc. so giving it time is wise, i will do this).

    anyways, i have the feeling all the LG Led tvs of this year have awful black uniformity.
    it has superb lag input for gaming.

    and i hate local dimming so i wont ever use it to 'deepen the blacks' LD is way too distracting,it is worse than clouding/banding.

    i will play with the backlight settings later tonight and see if i can get the bottom corner to look abit better.
    there is also an energy saving option which dims the screen quite alot and gets rid of the clouding (but then the panel looks too dark even with backlight up to 100).

    so i will try other things, and i do have those led light strips sticked onto the back of my tv.
    i generally like those, i never knew they could help with getting 'better blacks' though after i saw some video on youtube a while back.

    i dont believe it helps.

    anyways i hope it gets better.

    Holy sheep guys, had to quota ya fellas again because..

    the CLOUDING Is nearly ALL gone.
    70% of it.

    especially in the bottom right corner it was bothering me the most.

    the trick to it ??
    it was not rubbing/loosening the screws.

    i simply turned on my AC and set it to warm air and i turned it to where my tv is mounted on wall.

    and left it on for over 10hours and just now i turn on my TV and see the magic.

    now the panel is much more uniform and i sincerely hope it stays this way Whoo!

    here are some pics on before and after :

    Wow thats cool. I might have to try out this technique. How did you find out the AC trick?

    Wait, you just used heat to repair the damaged pixels? I didn't know heat even affected that stuff. I wonder if it would work for my laptop monitor with a cigar butt sized hole on it...
