He also misses a critical point about resolution. Yes, a 4K screen may have more pixels than we have cones in our eyes, but what matters is the detail level where we happen to be looking. He starts to talk about the fact that our cones are not uniformly spread out but rather are concentrated in the centre, but he fails to follow through to the conclusion that this makes the detail level of 4K matter--so we can see high detail where we're focusing our attention.
