The only market for 8k is movie theaters and megatrons. It’s absolutely not necessary to have it in your tv in your house. And it’s also insanely expensive to get the proper hardware to drive it at full resolution.

Even there it’s wasted. There is just no place between pixel density, size and distance for anythng much over 4k. Except maybe video walls, where you don’t see the whole image at once.

That’s what I meant re: megatrons (the giant video replay screens they have in a lot of big sports arenas)
