Television technology - where are we?

A neighbor recently installed a 82" Samsung 4K tv. I was fairly impressed and thinking about doing the same. Is there other manufacturers, models and or sizes I should consider. I want to make this purchase and have it installed in time for 2019 college football season opener.

I think it's safe to go with Samsung. I have 3, including a 75" I bought a few months ago. Great picture and reliability. Some say the OLED can't be beat, and they do look very good, but they also have a more limited dynamic range, and they aren't that much better to my eyes for the price difference. 
With the laser mentioned by dweller, check out Next Tech on YouTube for how they work, the latest, and how to save some money by buying direct from China for say, a 100" screen. He saved a bundle on that endeavor.

As for what you can buy stateside, I'd go with an LG OLED TV. Mine is almost two years old and the tech has improved dramatically. They've managed to boost the brightness to almost what a LED TV can reach, which by the way, is way overstated. LED TVs have been tested and found wanting in their brightness specs. 

What I saw at a local Costco (the LG OLED TV) froze me in my tracks. 
The price gave me the shivers too.

All the best,
Man I dread when my pioneer elite kuro plasma bites it!
