Looks like you already know the answer.

As for Value Electronics, here is their policy:

Returning a defective TV for advance replacement.

The following policy applies to all TV purchases. For LG ad Samsung TVs if your product is defective within 90 days of the ship date or 60 days from the day you receive the TV, whichever is the longer term. For Sony TVs we can replace a defective TV within 14 days from the day you receive the TV. This liberal policy gives you have the option or repairing the TV or we will swap it with a brand new TV. The defect may be subject to confirmation by the manufacturer's authorized servicer. You do not pay any restocking or any shipping costs, we cover all costs.

Exceptions:

1.) For TVs that were ordered with our full q/c, break-in and professional calibration that develop a defect we can only provide service through the manufacturers warranty.

I will add my opinion that the break-in and calibration not only give you the very best picture, but eliminates you having to play the "OLED panel lottery" game.

As a certainty, not really Salty as I don’t know what the deal is with 2020 and 2021 specific model/brand consumer OLEDs in regards to the topic of burn in. My personal practice with our older OLED is because of the opaque and controversial nature of the topic, i.e. one person says this…another person says that, etc.

and if I do get burn in, will Value Electronics replace the tv?” Can you definitively answer the question one way or another without hedging? And if safe, can you specifically list the models of the burn-in immune televisions? Just this morning at our local dog park, my neighbor who is a KC football fan and news addict mentioned that he is in the market for an OLED no smaller than 70”, if it is safe –

If these are your viewing habits then you obviously don't buy an OLED. Why would you want an OLED to watch a news channel for 4 hours/day anyways?

Well, I’m sure he does watch an occasional movie from time to time as we’ve discussed various films over the years. He simply wants to buy the Best TV in the size range mentioned and his kids have told him that OLED is the best, as well as salesmen at his local Best Buy when he was in there to purchase a computer and browsed the TV section.

If he is looking for the Best TV Size Wise, then he may want to look for an LED TV. OLEDs are awesome but if he isn't looking for the best in picture quality, then yeah an LED is the best bet, especially if he is super worried about burn-in. But again, most of the OLEDs out there have more preventative measures put in place for burn-in to not happen. I was worried myself but I vary my content constantly due to me watching regular antennae, streaming services, gaming, and movies. Honestly what worries me are the streaming services themselves, especially HULU. They recently came out with an update that whenever an ad pops up they show a yellow AD sign on the screen. It used to be white, which is much better for TVs overall. At least it only lasts 1 minute and 30 seconds.

At the risk of posing a potentially stupid question, does the LG's Dynamic Tone Mapping feature perform more or less the same function on HDR10 as the Panasonic's HDR Optimizer? Is it redundant or otherwise detrimental to PQ to have both features active at the same time?

Trust me, most all of us OLED owners have been there with that question. You may get varying opinions but universally, especially by top professional calibrators, will tell you to leave Dynamic Tone Mapping off in favor of the Optimizer. DTM does not perform in the same manner as the Pannys Optimizer.

Alone, the DTM function does not do well. But combining it with the Panasonic Optimizer seems, to me at least, do a great job at reproducing movies the way they should be. But as we have talked about many times, it depends on the TV year. My C9 is far different from a C8 or C7 when it comes to DTM. But overall, it does a good job.

yeah, na.....I know you like the look of DTM and what it does and that's ok. But It's been shown on all LG OLEDS to deviate from the PQ EOTF curve raising low black levels and mid tones. A function I believe created to combat the aggressive tone mapping of LG OLEDS that roll off way early with light cannon disc that the tv crushes down to preserve highlight detail.

Well to him, and I would imagine many folks, Best TV is synonymous with Best picture quality TV.

Nevertheless, in the absence of Robert addressing this topic, sounds like you think there can still be an issue with burn in, even on the latest consumer OLEDs? Personally, after being aware of more and more X300s suffering from burn in since - https://forum.blu-ray.com/showthread...r#post15259443
, out of caution, months later I subsequently moved our old OLED out of our master bedroom in one of our homes to another room in the house and use it exclusively for movie watching.

Anyway, if indeed there is still a question of potential burn in with prolonged usage of certain types of content even on 2020/2021 OLEDs, any recommendation(s) to my dog walking friend as to a BEST non-OLED tv in the 70 – 80” range be it either last year’s models still in stock or upcoming 2021 models? At this point, I feel I’ll burst his bubble in not recommending a 2021 OLED because I think he’s got his heart set on one, but what the hell, to avoid possible future grief…..

Most professional calibrators have said don't use it buy itself. But I haven't seen anyone test out how it does when adding the Panasonic Optimizer into the mix. I don't have any measuring equipment so I have no idea if it's off the PQ EOTF curve or not. But by my eyes, it looks right, especially with the Disney and lower end nitted films. I would like someone professional to test DTM and the Panasonic Optimizer out at the same time.

First time OLED owner here as of 12/20, coming from a Vizio P65-C1. Loving the deep blacks overall, but in near black material, I am aware of what appear to be black "blobs" and columns. Once you see it, you can't unsee it! It doesn't appear in video material usually, but I can spot it sometimes during nighttime footage in, say, X-Files episodes. Are these blobs and columns normal or should I exchange for another CX?

OLEDs can have issues with near black performance, but it can be more evident with "lesser" encodings that are bitstarved, so you're more likely to see it whilst streaming. There's also an issue with vertical lines with OLED panels (around near blacks), but I don't recall blobs been an issue.

Make sure your display is up to date and test patterns will confirm whether it's source issues or just vagaries of the panel. Check 5-10% grey fullscreen patterns.

The issue with OLEDs is that whilst they can turn pixels off, they have trouble just putting tiny amounts of energy to create near black pixels, so the step up from black and the next few shades can be hard to output.

What gamma setting do you use for SDR streaming? Reason I ask is that I had a lot of problems with bad macroblocking and "blobs" in a lot of SDR streams, and I realized that changing my gamma setting from 2.2 to BT 1886 went a really long way fixing most of it.

Spot on. And while near black handling has improved MASSIVELY over the last few years, it can still be tripped by low bitrate content as you say because it's got lots of digital shite contorting this way and that in dark or low-light scenes, and the voltage changes too rapidly for the pixels to keep up so they might end up 'pulsing' or going all 'blobby'.

Ah. So this explains that while watching The Vampire Diaries on Netflix (my wife is trying to get me into it) that in some dark scenes it seems rather blotchy and pulsy at times.

I set Gamma to 2.2 as that is what I am most familiar with from the Vizio LED. However, I will give BT 1886 a day in court...

I am on current firmware 3.21.16. I ran fullscreen pattern and can see the blotch in the upper left corner, and the columns on the right, reliably at 1% and 5%. They're nearly nonexistent at 10%. Should I live with it or try another unit, do you think? I have until Feb. 3 to decide. Thanks!

If it's a new purchase I'd give it a few more hours to settle down, the lines can be pretty common with OLEDs, hopefully the blotch will go. If it's still there in a week to 10 days and it's something you notice during normal viewing, I'd consider a replacement.
