LG 48CX

My CX is a December 2020. Though that's still 2020...

Well it's not like it has a 100% defect rate though right? The numbers are pretty high if you ask me, but obviously there will be some good panels out there. It's also worth noting that LG has probably sold MANY units so of course with more units sold = more chances for defects.

Indeed. Hoping for the best on this one as it ages...

(Actually, thinking back more, the CX might have arrived in the very same condition. Just a few dead pixels on the way extreme edges, so not bothered, but then it started losing more pixels. Hmm...oh well, crossing fingers and all that...)

Sounds about right. Most of the complaints I've seen online regarding the CX and dead pixels are people who bought 2020 models while those who waited for sales and bought it in 2021 don't seem to have this issue. Guess that's what we get for being the early adopters :D
I bought mine when the display came out and it's still working perfectly, no dead pixels or any other issues. I think I have over 8K hours on it as well.

Well again, it's not like there was a 100% defect rate on these panels. But if you look around online you cannot deny that the number of defects wasn't pretty high for these. You don't see other TVs having this many complaints about dead pixels. It's just like the RTX 4090 and burned out connectors. Yeah mine is still perfect to this day and I bought it early but I'm not gonna deny that the connector has no issues when it clearly does. I've just been lucky to not have it burn out.
 
Well, my LG CX 48" has started to have dead pixels at the edges. It might have been going longer because I didn't notice until I saw a full white background. It's pretty unnoticeable in real content so its disappointing more than a real issue.

Have had it for 4 years.

I am certain a lot of people who say they have no dead pixels just haven't noticed yet. If you sit at proper viewing distance you won't be able to see them. I probably have over 1000 dead pixels but because I can't see them in actual use I haven't gotten rid of my CX yet.
 
That is my suspicion too. But either way I believe the newer gens do not have that issue?

Yeah I honestly thought the display was just dirty until I got closer. I hope it doesn't become significantly worse from here.

I'd honestly prefer not replacing the CX for a few years more, have to move again around that time.

It will get worst but from my experience at least, it just stays limited to the edges. I don't have any dead pixels near the center where I am more likely to spot it so it's not a dealbreaker for me, just more of a disappointment as you said.
 
On the C1, I've not felt the need to go into the Service menu yet to disable the dimming. Possibly reflecting some more recent improvement in the firmware as opposed to 2023 anyway.

Yeah, I figure so. Totally worth it for this as yet unmatched combination of 4K + rolling scan though.

Never mind. Still broken. I'll be going into the service menu to disable.
 
My cousin finally got burn in on his CX after being burn in free for 4 years. Sad part is that it only took about 400 hours of one game to cause it.FFXIV Dawntrail with RTX HDR is the culprit. So if you plan to play a single game for hundreds of hours then this is something to be cautious about. Gotta say though burn in after just 400 hours is pretty pathetic no matter the scenario.

Gods that looks actually bad, unlike mine which is still far too faint to matter whatsoever. Even knowing it is here, it is far from having any impact on my enjoyment of the display.

I guess RTX HDR was pushing the HUD elements to maximum brightness in the case of your cousin though, greatly speeding up the process.

Thems rookie numbers.
I had something like 413 days /played in WoW before I quit at the end of MoP. Started playing when BC launched.

In the photo this burn-in looks absolutely awful. Panel looks ruined 🫣

RTX HDR... I have not used such technologies but I heard they can treat HUDs as highlights and display them extremely bright. In this case so quick burn-in would make perfect sense. HDR is expensive effect for OLED screens. For panel longevity its best to play in SDR at 100 nits and perhaps for long running games where HUDs cannot be dimmed or moved just playing them with lower luminance makes most sense.

What is strange is how sharp the burn-in looks - I would expect it to be smeared out due to pixel shifter.
 
How the hell do you do that? I feel like your cousin is lying and left it on or had brightness set to 100 or something. I've had 3 OLED for my PC going back to the think c6 and put 1000s of hours of gaming on them before moving them to other rooms and yet to get anything I can see in a grey screen after the pixel thing does it magic.

I keep my brightness at about 20-30 and don't really play any hdr games as I find they just get stupid bright.

He used HDR cranked to the max on a game with static content. That's just neglectful usage.

This is precisely why I haven't gone to OLED yet.

You are missing out man. The motion clarity at 120fps mixed with a dark game on OLED will blow you away. I had 2 55in OLED one was a old c6 used for years as tv/PC before upgrading to a 120hz 55 that I've been using for 4-5 years for 100%pc gaming. Never seen anything on a grey screen that I could identify as burn in. Also have a 77 in my living room for 3 years that pulls tv+console gaming and looks good as new.

Now I do have a old 65 b7 in my bedroom that at night looks like it has screen uniformity problems now but i think it's just getting old.

Il try to check my PC OLED tonight and take a pic for y'all to rib on how it looks after 4 years.

Why the hell would he lie about it? As I mentioned he played the game with RTX HDR so my guess is that RTX HDR treats HUD elements like highlights and blasts it at full brightness and we all know more brightness leads to faster burn in.

Yeah I am highly suspecting RTX HDR here. But even then it was able to burn in with just 400ish hours on a torture test like scenario.
 
BTW this isn't going to stop him from getting another OLED. He has the geeksquad warranty and is waiting for the C5 to come out, the C4 is too little of an upgrade. 4 years of zero burn in and this was only caused by 1 error of using RTX HDR in an MMO. Plus we know from RTings findings that the CX is actually trash when it comes to burn in, the C2 and up fair much better.

Interesting. I checked it and: no sheet!
CX is even worse than QD-OLED and there I was under impression its quite good from all the feedback from CX users.
C2 is much much better. 2nd gen QD-OLED is also pretty good comparing 12 months results.
Gaming monitors also have good results.

I wonder how my 48GQ900 compares - it was released the same year as C2 and should have the same panel tech.

This is precisely why I haven't gone to OLED yet.
My opinion is that if it interacts directly with the sense/body it should have higher priority than anything else.
We live like what, 60-80 years? Out of which if person spends few hours a day watching display or listening to music then saving few hundred bucks once in a few years on appropriate hardware might make no sense.
Of course for as long as person can actually afford such expenses.

The thing is people usually spend tons of money on some things which they don't really experience and then save small amounts of money in comparison on things they do experience multiple hours a day. In this case it doesn't make any sense.

Of course there are special considerations and I would not necessarily say OLED is the better choice.
To avoid completely just because display might develop some burn-in after few years - makes no sense.

I agree life is far too short to not be enjoying it. I game every single day so I aim to have the best experience possible and if that means living with burn in then so be it.

I think you misunderstand me. I absolutely agree with you. I haven't gone to OLED because I'm concerned about burn in. I use my computer far more than a person should and static images are on display all the time. If it isn't the start menu its going to be some HUD elements of one of thre few games I put a crap ton of hours into.

You're fine as long as you're not using it as your main monitor. If you're just running a very long HDMI cable to a TV and playing that way it's okay. People using TVs as monitors, or even using OLED monitors as productivity monitors are going to have a bad time.

I'd be using it as my main monitor if I went that route. I'm not interested in switching between completely different displays just to play a game.

Because saying something like man it just happened is easier then saying I accidentally forgot to turn it off overnight or something.

IDK that just looks like it went a long time without running the pixel refresher in-between ues to be that defined.

If you wanna be a burn in denier then be my guest but like I said he went a solid FOUR YEARS with zero burn in, not a slight hint of it which led him to believe that the CX is more resistant to burn in than it actually is. He didn't do anything stupid like AFK in the game while leaving the TV on or anything like that, yes it was freaking turned off overnight as it is every single night so it can run it's pixel refresher. I'm just gonna leave a warning for anyone who wants to use RTX HDR in a game with static HUD elements and they plan to spend hundreds of hours on, do so at your own risk. RTX HDR will treat HUD elements as highlights and blast it with full nits so you'll just accelerate the burn in to the maximum rate. Four years of solid use pretty much got wiped out within a few hundred hours due to that.

Better off sticking to IPS or VA with miniled if you want longevity IMO. I fished an HDMI cable through the wall along with a usb cord for a hub so I can lay on my couch. I still don't think the Neo G7 is a bad monitor if you don't mind the curve. Brightness levels in 10-30 percent windows beats any OLED on the market, it just struggles a bit with full screen and sub 2 percent it has to dim a lot to not show haloing. It's still brighter in most scenarios than any OLED, certainly brighter than my S90C in most scenarios. The graph is the brightness levels of the monitor, just with different local dimming settings (low is useless, you can just leave the monitor on auto for the most part.) I play on both, just depends on my mood. I don't think one is preferable to the other but I don't pixel peep and blooming on occasion doesn't bother me.

You guys. When I saw this thread blowing up today, I dared to believe it would be for a happy reason.

How many hours on the panel? I guess with 4 years on the panel already, you believe there isn't enough reserve left to recover from this during the next compensation cycle?

RTX HDR Peak Brightness was set to how many nits?

OLED Motion Pro engaged? (Not as popular with most as with me, but maybe it takes some of the load off of the pixels...)

(HDR is scary with it maxing out the OLED Light. And that supposedly being the correct thing to do, because the source is supposed to control as I understand it.)

11,457 hours over 4 years. You cannot enable motion pro if VRR is enabled which is what he's using. RTX HDR set to 800 nits which is the peak brightness of the display. I don't believe it would run out of reserve with 11k hours since other users on here have used their CX for even longer than that like 15,000+ hours and still do not have burn in. I really believe it just came down to the combination of using RTX HDR in the same game containing static UI for hundreds of hours and the CX itself being pretty weak when it comes to burn in. He has not played any other game for that long, the longest he would play a game for would be in the 100-150 hour mark for games such as Persona 3 Reload and Baldur's Gate 3 so simply not long enough for burn in to start developing. Newer OLEDs using deuterium would fair much better than 400ish hours but I would still caution against it if you want your display to last a long time because the key takeaway is that burn in is going to be related to brightness. More brightness = faster burn in.

I remember a thread where it happened from MTG card game played constantly. Very static board/table elements. I think alot of people leave the screen on when they aren't looking at it though too, some crank the brightness more than necessary, and if they disable asbl they also removed a layer of default protection.

I'd ask if he left the screen paused/static when afk, and if he disabled asbl. I always use the "turn off the screen" function when I'm not looking at the screen for awhile or when I go afk . That turns off the emitters only, kind of like minimizing the screen until you go back to focusing on it.

I always thought it would be a cool feature if they added masking overlays to gaming OLEDs, like dragging a selection box over a ui as a rectangle or an oval, then setting the opacity/transparency, darkening it. If they had a handful of selection sets you could store like that it would be pretty neat. Would also be useful for streams and news broadcasts where the is a bright static light source in the frame for no reason, or junk banners and adverts, etc.

Other than that, maybe on a good enough stand, you could rotate the screen upside down and flip the output in windows every so many days if you are a mmo lifer (no judgement), so your HUD would hit a different spot. :ROFLMAO:

lol look at this point it doesn't matter what he did or didn't do, the point I'm making is that you CAN get burn in relatively fast if the conditions are right so people should just exercise caution. I've seen too many posts bragging about zero burn in after X amount of years/hours, well same exact case here, zero burn in for 4 years/11,000 hours and it all went down the drain very quickly.

Thanks for the heads up! RTX HDR + OLED not without risks per your above. (In my usage, I'm hoping rolling scan + low peak brightness set will mitigate, but that maxed out OLED light in the display's settings during HDR still makes me a bit nervous.)
 
Think of OLED pixels like... wooden torches? Any time you use them, you are eating away at their brightness capacity (and the higher the brightness, the faster the process), until there is simply not enough left and you notice it (there is a safety buffer, so that we can thankfully burn the pixels for a while without noticing anything).

Heat supposedly makes them age even faster but I have no data on that. Those like me who keep the display powered on for 12h a day or more are probably burning the pixels faster, even with a lot of breaks where the pixels are black (the screen off function, and dark themes).

What probably happened with MistaSparkul's cousin is that after 11000h, that part of the screen had already seen heavy use, and the brightness buffer was very close to exhaustion. Shooting HDR levels of brightness at that part of the screen for a few hundred hours made quick work of whatever was left in that buffer. It's that not that specific game's fault or RTX HDR per se, it's the accumulated wear on those pixels. RTX HDR was just the finishing blow.

Yeah I guess that's part of the story. But let's say we take a fresh out of the box unit and start gaming in RTX HDR on it, would it still last 11,000 hours? I'm betting it won't, but it probably wouldn't get burn in within 400 hours also. I believe all of RTings test are done in SDR with max brightness which actually isn't very high for the CX the SDR brightness is like what 150-200 nits? So yeah waaaaay lower brightness than what RTX HDR is pumping into the UI.
