The resolution of the human eye (with 20/20 vision) is about one minute of arc. For full HDTV resolution, this one minute of arc implies that the TV watcher should sit 3.2 times the height of the screen away (optimal viewing distance). At this distance, the individual pixels cannot be resolved while simultaneously maximizing the viewing area.
Readability is the ease with which a reader can understand a written text.The concept exists in both natural language and programming languages though in different forms. In natural language, the readability of text depends on its content (the complexity of its vocabulary and syntax) and its presentation (such as typographic aspects that affect legibility, like font size, line height ...
This also means one UXGA 20-inch monitor in portrait orientation can also be flanked by two 30-inch WQXGA monitors for a 6320 × 1600 composite image with an 11.85:3 (79:20, 3.95:1) aspect ratio. An early consumer WQXGA monitor was the 30-inch Apple Cinema Display, unveiled by Apple in June 2004.

[ 1 ] Because of the lack of technology at the time, naked-eye observations were used to observe eye movement , until later in the late 19th and mid-20th century eye-tracking experiments were conducted ...
The apparent PPI of a monitor depends upon the screen resolution (that is, the number of pixels) and the size of the screen in use; a monitor in 800×600 mode has a lower PPI than does the same monitor in a 1024×768 or 1280×960 mode. The dot pitch of a computer display determines the absolute limit of possible pixel density.
