- StavrosK 12y agoThanks, that link says 300 ppi (magazines) and 720 ppi (fine arts prints). Very informative!
- IkmoIkmo 12y agoThe link seems to confirm the 400+ range is getting useless fast for anyone who isn't a baby holding the screen to their face.
- 3A2D50 12y agoThe link provided by avree says, "...But the legally accepted norm of 20/20 vision only asks for 876 ppi/dpi at 4 inches!" A baby's vision is around 20/800 [1] (extremely poor).
