It's not about the number of rods and cones, the question is the optical acuity of the eye. Someone with 20/20 vision has an acuity of about 1 minute of arc (1/60th of a degree). At living room distances a 4K 65" TV has pixels so small someone with perfect vision can't make them out. An 8K resolution is a waste. For 8K to be actually visible you're talking about TVs that take up the whole wall of a living room.
- redox99 4y agoThere are other types of acuity, such as vernier acuity, that are much more accurate. If you had a "human sized" display (let's say 2m x 2m), that you could stand next to, and it showed footage of a real size analog caliper that you had to read, I wouldn't be surprised if you needed something like 128K video or more. But I agree that for regular video content, 8K is good enough.
