The NHK lab also tried to wow visitors with eye-popping 8K video of parrots and chameleons projected on a 450-inch movie theater screen. The 8K projector was developed by NHK and JVC and can take full-spec 8K signals at 144 Gbps through a single optical cable.
For smaller displays, however, the difference between 4K and 8K resolution becomes difficult to see, raising the question of whether there will ever be a 16K resolution standard.
"We've studied the human eye and find that it cannot distinguish resolution, in terms of 2D television, beyond 8K," said Kenichi Murayama, a senior manager at the lab. "So NHK isn't talking about going another step beyond 8K."
