Sorry, but I call your post dumb. How can you possibly say that you like Plasma better then 4K UHD or OLED?, That is a stupid statement. It means that you never really looked at OLED (to say something like that). Also, BSA, your Plasma's life span is 60K.
Geez you really either don't get it, or are just stringing people along.
Screen resolution is NOT THE SAME as display technology.
Know what a 1920x1080 OLED is? It's 1920x1080, and it's not UHD and it's not plasma, and it's not LCD. It is OLED, it is full HD, but it's never going to be UHD, and it's never going to be plasma.
Why does someone prefer plasma to UHD LCD technology? Because the Kuro and other plasma displays have a black level which is far superior to LCD, and it has a much better viewing angle than LCD can deliver. As well, resolution only matters when compared to viewing distance. Someone sitting 12 feet away from a typical 55" or 60" television gets zero benefit by going UHD over Full HD. Yes, yes - I realize you want to argue this fact, but your opinion of the fact, doesn't change that it is a fact. It just makes you look really uneducated on the subject matter.
Now, OLED is a great looking piece of technology. I'm rooting for it. Moreso, I'm rooting for manufacturers other than LG to deliver on it, or for LG to really update their quality in manufacturing so their power supplies don't fail, and their pricey OLED displays to start failing the same way all their LCD displays have been. IMO, this is a big issue for LG, but I also believe that they have been improving as I haven't heard the same level of complaints as I have in previous years. So, thumbs up on them for that, but it still is a legitimate concern for people to have.
So, we have OLED displays which really do look great. They are a premium product and really are the best technology ever in terms of image quality. Their longevity is really not yet determined.
Behind them, we have plasma displays which have excellent image quality and the best black levels and contrast with great color. A step behind OLED? Yes, a step behind OLED. But, until OLED came to market, the Pioneer Kuro displays were the benchmark for quality. No other technology looked better. Period.
Then we have LCD displays and the long list of implementations of those LCD displays, including Samsung's most recent entry, SUHD, which is their take on quantum dot technology... which is really cool. But, it's still LCD, and it is still playing a game of catch-up to plasma, let alone OLED.
Not once in that previous discussion of technologies did I talk about resolution. Not once.
Resolution is a different discussion and is based entirely upon screen size as it relates to viewing distance. It's a pretty straightforward ratio, but the real benefits of UHD start to come into play at screen sizes that are about .66x the viewing distance in width. So, if you view from 9 feet and you have a screen 6 feet wide, then UHD matters.
Most people don't have screens anywhere that large, and sit further away than 9 feet. So, UHD is nearly irrelevant in terms of resolution.
The other benefits of the newest displays, which include HDR and the expanded color palette (REC2020 I think), may prove to be extremely valuable, and another item which OLED can use to drive the quality forward, regardless of resolution.
