A Dataquest marketing study distributed at a 1988 Bay Area SIGGRAPH meeting
stated that 2K by 2K was optimal COLOR screen resolution from a visual
physiology point of view. (Maybe twice that for monochrome).  They concluded
that this was one of the major factors for CRT not getting larger.
(The other reason is probably the electronic switching limits of single gun
CRTs.)  I remember the medium price ($25K-50K) color graphics terminals
growing from 480 to 1024 scan lines from 1980 to 1985, then essentially
stopping their size increase (but not their price decrease).
