Our sense of sight as humans cannot differentiate 4K video vs. standard full HD video
If you're looking at a 17" laptop doing 4K, I'm with you. I don't know why these even exist. Personally I'm now used to my 1080p projector, showing a ~120-inch image. A friend of mine has a 4K projector, and his image size is roughly the same as mine. My eyesight is no longer being what it used to be, but even with that taken into consideration, I can absolutely say without hesitation if someone couldn't tell the difference between the two, it's time they booked an appointment with their eye doctor. 4K and 8K? I can't make the same argument, but that's mainly because I haven't *seen* any 8K video playing at native resolution. But I *do* suspect that's beyond the point of diminishing returns.
