New viewing distance chart (1080p, 4K, 8K, 16K!?)
New viewing distance chart based on recent study done by Japanese NKH (guys behind UHDTV standard).
Beware, this may come as a shock! :D
Study showed humans can perceive angular resolution up to about 200 pixels per degree.
Full resolution here.
If you have any questions about the way this chart was made, any requests or you just want to discuss it - go ahead!
