There has been a rapid increase in the resolution of small-sized and medium-sized displays. This study determines an upper discernible limit for display resolution. A range of resolutions varying from 254-1016 PPI were evaluated using simulated display by 49 subjects at 300 mm viewing distance. The results of the study conclusively show that users can discriminate between 339 and 508 PPI and in many cases between 508 and 1016 PPI. © Copyright 2013 Society for Information Display. Source

This study aims to determine an upper discernible resolution limit for smartphone displays showing video. A range of resolutions varying from 150-600 PPI were evaluated by 43 subjects at 300mm equivalent distance. Results of the study conclusively show users can discriminate between 450 and 600 PPI video playback. © 2013 Society for Information Display. Source
