Funny.
Unless one tv is 8k, it wont beat another 4k tv in resolution, maybe detail.
And plasmas are stuck at 60hz, and i cant watch it for more than a few min. unless that changed in past years.
Qleds arent (lcd screens) tech, just color enhancement, and because they are lcd, they will never experience burn in/image retention, showing some ppl are just regurgitating samsung crap.
Its like claiming you will never get stuck in snow, because you live in Florida, when your car is a 4x4.
There are different models for oleds, and i have seen image retention on one we had on the display within a year (the lg logo showing after each demo vid was retained), also have a couple of lg customers that asked me how to fix it on their tvs.
And they don't cover image retention, because they don't want ppl to swap their tv for a new one once a year.
Same why no car maker will cover any damage to a street legal that's been used on a race track.

When I bought my C7 I read about people with earlier OLED models getting denied requests for burn-in issues with LG. Infact I remember one guy posting an email response from LG saying that the image retention he had was from misuse of the TV. Apparently playing games on a OLED TV for too long is misuse according to LG.
That being said the newer OLED tvs heavily mitigate the burn-in issues. I've personally left my screen on for hours a time with static images and have no issues - I'm sure the C8, C9 further improve on this. RTINGS has some burn-in tests going - they showed slight image retention on a C7 after 6 weeks running CNN ~19 hours a day (i forget the exact amount of hours too lazy to look it up). So it's still clearly a problem but I don't think under any normal use you'd see it. I bought my TV with the assumption that I'd replace it in 5 years - so as long as I have no burn in within the next 3 years I don't really care. The image quality improvement over the Samsung/non-OLED sony's and stuff was just too good to pass up.
Regardless, if Samsung found a way to do self emissive QLED it's a pretty big deal. Should provide all the improvements that OLED does with non of the downsides. Perhaps my next TV will use that or MicroLED - although it still seems like MicroLED is at minimum 8 or so years off from mass scale production.

So what?
LCD dont degrade? I mean, are ppl blind or only just me sees more and more clouding and picture degradation on any LCD I had, have, or seen in my parents home or sister? Dead pixels after week, year or three? Dont exist or it is just flea shiet?
And sharpness/contour behaviour...damn that thing suck. I cannot watch LCD TV from less than 2m, I just see how it suck.
I bought OLED c8 last year, December. No issues. I even connected PC to it, no issues either, and picture was perfect compared to my monitor.
2 months ago I purchased OLED TV b9 for my parents and, coming from Philip's fhd TV 8yo they are just delighted. They are not tech heavy, but they clearly see differences on same source(aerial fhd ) and as I connected they to my Netflix account they see what proper picture should look like.
Now they are in process of installing cable TV, just to make signal and picture even better. And watching experience better.
And guess what, if it fail in 3-6 years I would not cry, just buy new TV. Hope there will be nonorganic or microled diodes TV available at the time, but if not....
Who cares?
Personally if I could buy now in below 1k price range 1440p monitor, OLED or mled I would not hesitate.
120hz+ ofc.

Not every tv is the same.
Just because one didn't look good to you, doesn't mean they all do.
E.g. The lcd based z9g side by side withe a9g will produce the "same" picture, so far i haven't seen anyone that could tell the difference.
Sure, once i know what to look for, you can point out they arent (overhead shot from a city at night etc), but its not something a regular consumer will notice.

OLED screens look great, but it's true that they have a little less brightness than high-end QLEDs and they also have the burn in problem.
Let's see if Samsung will soon release these QPLED models and LG will release 48 or 49 inch OLEDs and lower the prices of good TVs.

Again, qleds are "regular" led driven tvs, not tech, and there is no "burn in" on oleds since they arent plasmas.
There only is the possibility for image retention, since the blue oleds degrade faster, and the green/red will make the area stick out.

have very good contrast ratio - though not infinite - and black uniformity. They achieve this with full-array local dimming and aggressive screen coating, though at the cost of reduced viewing angles. LCD-based display also have better peak brightness by using more powerful LEDs in the backlight.
But of course slow GTG pixel response times and limited viewing angles of the LCD panel are not going to improve. That's why Samsung is investing $11 bn in converting their 8G plants to QD-OLED panel production, which uses blue OLED layer and inkjet-printed photoemissive red/greed QD color filters. This would result in cost advantages over WOLED with RGB color filters. This decision follows pilot production tests that were performed throughout 2019, and QD-OLED technology will not enter consumer market until at least 2022-2023.
Previous announcements described ink-printed QD color filters to be used with LCD displays, but this design proposal ran into difficulties with the in-cell polarizer.
Now active-matrix electro-emisssive (electroluminiscent) QD-LED (ELQD, displays - which use quantum dot LEDs as direct light emitters in the subpixels and do not require color filters - are even farther away, probably 2028-2030 at the earliest.
But these are not really new. Prototype QD-LED displays have been tested and shown for a few years now - including NanoSys demo at CES 2019 and CSoT demo at SID DisplayWeek 2019 - and each time they're a moving target that's still '3-5 years' away.
Improved quantum efficiency of Cd-free materials is sure welcome, but researchers first need to devise methods to inkjet-print individual LEDs for each subpixel on top of TFT (thin-film transistor) matrix before mass production of QD-LED displays becomes economically possible.
Whatever it's called, OLED pixel degradation is real, just like the burn-in effect of PDP displays - which ultimately failed in every public announcement system they were installed in.
Even if this degradation only affects certain use cases, specifically news programming displays, it's still a factor to consider.
PDP and FED/SED are unlikely to ever re-enter development and production - they are not as power-efficient or cost-effective as active LED displays, and especially ink-printable OLED/QD-LED.
The latest QLED panels, as well as traditional LCDs with high-efficiency phosphors, fry178
At one of the internal training session from sony i asked one of the r&d guys if we anything coming that would "replace" lcds that aren't oled, and he talked about some sort of micro led tech (called crystal something), but that was 5y ago.
Dont think thats coming soon. 🙁

Can't see how it's 'overblown' when it's a real concern for a significant number of users. I have a 50-inch TV set that works like 8-10 hours a day, mostly with news programming and talk shows, and this usage pattern would completely rule out OLED for that specific room, because according to burn-in test resuls from Rtings.com I might get image degradation issues after only two years.
Sony's Crystal LED has been released at CES 2019. It's a modular video wall system for theaters and indoor signage.
Each display tile is a 15 7/8 x 17 7/8 inch, 320 x 360 pixels mLED panel with peak brigthness of 1000 nits and DCI-P3 color space coverage, which costs south of $10K.
So a 218 inch 4K display (12 x 6 panels) will set you back $720 000+.

That looks like 108 inch 1080p configuration with 6 x 3 ZRD-2 display modules ($180 000+).

Well, i meant for consumer, otherwise you would need to compare it to bvm based oled 😀
