I've realized that I can still buy dumb TVs (for now), but their resolution will top out at 1080p. And that's fine as it's still Blu-ray resolution. Despite having a Chinese brand 4K TV since 2014, I haven't come across a single piece of video content that I felt I "must have" in 4K.

For video games, you can still buy 4K monitors and play them on that.
