In your first post you asked about Sony BRAVIA or BRAVIA OLED.
In my first reply I provided a video, now deleted because the young 25-year old reviewer was simply swearing a lot, way too much for a hi-end class of civilised people like us here. I agreed with Gordon, and removed it.
That Sony Bravia TV was this model, a FALD LED TV, the X900E:
I am not an expert on TVs, I just read the reviews from the pros and the owners, to learn for myself like anyone else. In one of my above posts the two TVs I mentioned are considered the two very best. They are both the 2017 models, and without the 3D feature, of course.
Some older 4K TVs, LED and OLED (Plasma is dead, and never made it to the 4K territory), from Sony and LG had the 3D capability, the 2016 models, some of them, and from previous years of course (3D is dead dead in 2017 TVs).
* I posted that short video above on the Sony Bravia X900E because I thought it was interesting to see where the 4K TV world can take us from the professional expert reviewers.
Image burn-in is certainly a reality with OLED, as it was with Plasma.
And it depends of each viewer's habits. In another thread I provided some educational links...LG OLED screens from their android phones and from their 4K TVs.
A year from now we'll learn even more, and in 2018 new 4K OLED TV models will be introduced.
...And with HDMI version 2.1 jacks. The times, our time is flying fast, and it will fly even faster tomorrow.
For now, today, the Sony A1E and LG C7 OLED 4K TVs are considered the very best.
I celebrate with great joy with their owners, in in particular with the Sony Bravia model A1E owners because I prefer its design, engineering, video processing chip, latest technology in TV sound, and overall awe...performance and romance.
I'm happy too for Sony, and LG. They are living in the best of our times. ...Even without 3D because I understand the technology and business process.
