My 55&quot; 4k TV has pixels visible pretty much from distances under 1m. I use it for showcasing my photography portfolio, looks much better than on 1080p, as well as to review my hyperlapse movies and that&#x27;s about it. 8k on a smartphone will be different though, but why? 720p on 5&quot; is close to &quot;good enough&quot; for median vision of population.<p>8k is supposed to be the &quot;final resolution&quot; of TV as it should bring retina-style to people with perfect vision (not to eagles though).
