Our Verdict. The Sony A8H OLED and the LG CX OLED are almost identical in performance. The Sony delivers slightly better picture quality, as it has better gradient handling and a much better color volume.
NanoCell TVs use Backlit LED-LCD displays with a special coating for a sharper image. OLED is a completely different technology and OLED TVs emit their own light. There are several significant differences, but among the most important are that OLED TVs have the best picture quality, but NanoCell TVs can be brighter.

The tv have image shifting technology to prevent it. The only extended warranty that cover burn-in is the one that offer best buy. So if you are planning to purchase this tv i recommend the extended warranty from best buy. Yes, according to their warranty page, it does.
Every emissive panel I have owned (plasma and OLED) have had a least one dead pixel. The 2 LCD tv's I owned never had any dead pixels. Of course, LCD is a non-emissive panel.
Calibration takes more than an hour.
- START ONCE TV IS OFF : Press the Power button to turn off the TV when you are done watching. The Pixel Refresher will start running.
- START NOW : Your TV turns off immediately and the Pixel Refresher starts running. The TV will automatically turn back on when it is done.
Screen Shift moves the pixels of the static area. and three hours today (more than four hours in total), Pixel Refresher will automatically run, deal with potential image retention issues and reset its operation time. *This function does not initiate if the TV is not plugged in.
Definitely don't try your luck and think that you'll only have to deal with temporary image retention. Keep in mind that all OLED screens, no matter the brand, are susceptible to burn-in, and if it ever gets to that permanent level, you'll likely have to just live with that imperfection on the screen.
The automation includes a few minutes of pixel refresh after every four viewing hours (continuous or not). 3. To manually activate Pixel Refresher, you will have to select Picture → OLED Panel Settings → Pixel Refresher in the settings. Once manually activated, the function will run for approximately one (1) hour.
NorthStar said: Plasmas, OLEDs, both are prone to permanent burn-in as they are both employing emissive technology. Today more security measures are in use, through software updates, and advanced features to protect against permanent burn-in. The best plasma TVs are the Pioneer Kuros.
To be considered as screen burn in, these artifacts have to be permanent and are a defect caused on the display hardware side, rather than a graphical glitch that may be caused by software or a problem with the display driver circuitry.
Black bars do not burn in, because only activated bright pixels degrade or age "faster". In the really long run the only effect you might see is that the area's of the black bars are just a bit brighter with full-screen video and stil black as ever on movies.
OLED is a fundamentally different technology from LCD, the major type of TV today. QLED is a variation of LED LCD, adding a quantum dot film to the LCD "sandwich." OLED is "emissive," meaning the pixels emit their own light. QLED, like LCD, is, in its current form, "transmissive" and relies on an LED backlight.
You will see screen burn in maybe after 2–3 weeks (possibly earlier).
Over time, the compounds in an AMOLED display degrade – just like the components of batteries do – and as they do, they can leave ghostly images behind in the areas that have been subjected to the most electronic wear and tear. That's AMOLED burn-in.
