LG 48CX OLED - 4K 120 Hz

Like many have said before burn in is cumulative. If you constantly have static, bright especially hdr content then assured you will get it. How long it takes is the question. Yes the panels are more resistant with the red pixel being increased in size and the burn in preventive measures LG have done like pixel shift, logo luminance etc. If you have an OLED and play games constantly or use it as a PC then that is a risk we all have to be prepared to take. For the record I have a C9, 14 months old. I play maybe 2 hours max a day, when I was playing RDR2 and Doom Eternal, in HDR, maybe 3 hours. I have no signs of burn in with 3000 hours of mixed usage. Only problem is I have some dead pixels now and a new panel is being fitted Monday.

I just can't take the risk for that money.

£1500 is a boatload of money for me and any risk is too much risk.

The only way I could even consider it would be if there was a lifetime warranty against burn-in when using it as a monitor.

LG won't do that and it's simply too much money to take *any* chance. It's like a month's wages :p

Yeah you're not wrong, the burn in risk is something you need to be comfortable with. I did a lot of research myself beforehand, you can read the avsforum thread on burn in for example. C7+ models LG changed the subpixel structure to make burn in much less likely, I believe rtings measured over 3000 hours with a bright static logo at 100 OLED LIGHT before they got burn in on these recent models. Few people experience burn in on C7 or later, but of course those models are only a 2-3 years old so we may get more reports as time goes on. Just check the avsforum thread - it's basically dead these days. Even people using these as PC monitors experience no burn in with 4000+ hours of usage.

Using it for PC content obviously increases the risk though, but I think as long as you take precautions (use dark mode everywhere, ensure all protection functions are on, and use low OLED LIGHT), you are probably okay. But it is not going to be 100%. I personally think the PQ is worth it, and a large screen is worth it. I have thought about getting a secondary monitor to work on instead, but I don't have the desk space so it would be a huge pain. But you can do that and then your screen will probably last forever with light usage.

3.21.16 firmware apparently fixes the brightness drop issue, some guys are testing it already.

Its available via the engineers menu hack not something I would recommend unless you know what you are doing and desperate, but its good news.

Maybe buy from John Lewis and get the burn in protection for £140 and use your LG CX which ever way you want imo.

These engineers only take 25 minutes to swap out the boards to the new panels anyhow and LG re-uses the faulty screens.
 
Someone over at avf has confirmed the new 3.21.16 firmware fixes the brightness nits issue, guess it will come soon enough
 
When you say re use the panels in what way? If I have my panel replaced I would expect a new panel. If I have a refurbished panel for lack of a better word then how do I know the new panel does not have 5000 hours of usage on it?

Id guess its recycled and made into new panels though, would be even more problematic if they attempted to repair it given burn in and other issues with wear and tear.

The engineers usually come with a brand new panel and sometimes new casing but its missing the mainboard, power board and cabling, so they simply remove the ones from your unit to the new panel shell.
 
Just doubled checked the panels get repaired and put into refurbished TVs, well according to one engineer shown here:


So that must mean LG just use brand new OLED panels and do the mobos swop for a quicker fault free fix like shown in the video. Still not sure that engineer is correct though flebay has had some LG OLED refurbs and its mentioned a new panel has been installed, so guessing they used the existing mobos which could have been months or years old.

Just look at that comedy show of a video lol. No anti static straps, getting a shock lol If you see the follow up video he got a substantially worse panel, banding etc.

P. S

I have built dozens of computers , personal use so my risk, and never used anti static straps. But if you are a professional I would expect you to do so.

Real Life OLED Burn-In Test on 6 TVs - RTINGS.com

Ignore their first tests which were done on max brightness and with a test pattern.

The tests on that page were done with real-life sources (like CNN) on normal brightness.

Check the CNN image at two weeks on the magenta colour. Already you can see burn-in from the ticker-box in the lower left corner. So you know what you're looking for start at like week 10 then go backwards. Once you see it you can't un-see it :p At week two it's pretty faint but detectable.

RTINGS is totally unbiased and very rote in their evaluations. They are trying to be unbiased based on measurement but measurements and scores offer biases of their own and lack the comprehensiveness of viewing. And most of the time they try and push you in the review to buy the TV of there choice.

OLED isn’t a new technology it started in 1987, with Kodak digital cameras, Sony, for example, released their first OLED TV in 2004 in 2010: LG enters the market they created the LG 15-inch 15EL9500 OLED TV. In 2012, the first 55-inch OLED TV panel television,

So you don't own or never had an OLED, but you quick to find fault on LG and there OLED panel to justify your question not buying one that's your choice, but the CX model was design for a PC monitor and gaming use, I think most of us LG owners did there home work before they bought the CX 48/55 model in 2020, with the new LG features Pixel shift and Logo luminance the burn-in is one of many big two sided debated topics on other forums and most C9 owners who play games on the LG OLEDs haven't seen a burn-in yet! To justify RTINGS testing.

Nah that's not right. I'm not "quick to find fault" with OLED at all. The picture quality of OLED kicks the ass of ANY PC monitor. If you knew me at all you'd know I'm very critical of the absolute state of the PC monitor industry, with the same old crap VA and IPS panels and the astronomical prices these mediocre screens are now reaching. £3000 Asus monitor, anyone? Yeah, no thanks.

I'm down with OLED picture quality believe me. MicroLED might eventually beat it but nothing on the market today comes close.

But if I'm spending £1500 that's not something I do every 6 months :p For that money the thing has to last 8,9,10 years or more. Not 1 or 2 years. It has to last me the best part of a decade for that money.

So put your pitchfork down.
 
Then I judged you wrong and will put down my pitchfork:D I too paid £1599. for CX 55 model and I will stay with OLED in future, not going back to LCD/IPS. IF you buy a CX model from JL you can take out the anti-burn-in insurance they offer a few members on here did the same for 5 years

OLED Burn-In Risk Is Overblown

OLED truly beautiful, the clarity is just another level over your standard VA and IPS panels imo. The viewing angles are excellent, sure the blacks, colours, angles are not perfect but still much better then VA, IPS.

I hear you £1500 way over my budget @ first, usually id spend £500-800 tops and never ever think about the 1K+ range but covid and the TV being the main window I wanted to treat myself to the best since rarely do, its the single most expensive hardware I have ever bought also.

I love my Films and TV series and figure why not get the best source material (4K UHD remuxes) and the best screen to display it.

Hopefully in 5 years time once my John Lewis 5 year burn in and accidental cover runs out D&G will offer me an option to purchase an extension for a reasonable price, but id probably upgrade it at that point and hopefully get a decent price or move this beast to another room.

I wont be shocked if we see 48CX get a proper drop to 1.3k within 6 months time, you get refurb, store returns on flebay for £1.2-1.3k already and some with 5 year cover time to time. C1 series will be looming and perhaps drop price further on the CXs perhaps mid-late this year.
 
Well i am on 26 months with a C8 and zero burn in, most channels i watch have some sort of banner at top of screen just vary the content and it's fine, loving my CX48 on my pc will never go back to bog standard pc monitors. :)
 
getting the cx48 was worth it and using it as my daily driver for everything watching movies, playing games and pc related stuff, took the risk after researching months on what monitor to upgrade to, and yes pc monitors are really overprice now, i just hope she doesnt break cause no where i can get a warrantly here in my place we dont have this model here and shipping and customs alone cost me $800 but its worth it

Christ. Where do you live?
 
These can now be picked up for £1259-1279 from major retailers. What do you guys think?
Should I return my odyssey g9 (£900) and get one? Or return and wait for the curved 48 oled..
