8K exists, and will be in use for at least some of the 2020 olympics.
why will 5-10 years make any difference? Will living rooms become larger?
I mean that I am not very sure the human eye can even distinguish between 4K and 8K, provided at least 60FPS.
IMO we're hitting maximum levels beyond which there's no sense to continue -- except to sell us the latest and the shiniest.
Required resolution depends on field of view, which tends to be well under 40 degrees required for "movie" style experience for most people even now
However 4K isn't worth it until you get over 30 degrees, and any higher isnt worth it unless your tv is too large, at least with modern cinematic techniques.
• Bigger screens.
• Much better screens (like QLED by Samsung).
• Better hertz values (doesn't irritate the eyes).
• More "smart" builtin software and firmware, with tons of bugs and security holes.
• Bigger resolution.
I'd take all of the above points except the smart TV software. To be perfectly fair I also think 4K is the absolute maximum for resolution that we need to use on TVs for like 5-10 years, too. As many people pointed out in the past in other threads here in HN, I'd love for these TVs to come in two packages -- with and without the hardware module that gives it its "smart" software.
Alas, we don't have the choice. Our best course of action is:
(1) Never give our TV access to our WiFi network.
(2) Make sure to buy an HDMI cable with lower protocol version so it doesn't pass-through your Ethernet connection.
It's a pretty screwed up market. I bet 10-20% of the price of the modern TVs comes from the supposed value proposition of the "smart" features and our group of users pays this premium without needing it.
