The Jargon File (version 4.4.7, 29 Dec 2003):

screen
 n.

    [Atari ST demoscene] One demoeffect or one screenful of them. Probably
    comes from old Sierra-style adventures or shoot-em-ups where one travels
    from one place to another one screenful at a time.


The Free On-line Dictionary of Computing (30 December 2018):

screen

   1.  A generic term for a display device that shows
   text and/or images on a roughly flat rectangular surface.  The
   most common type is usually refered to as a "monitor" and is
   based on a cathode-ray tube, though flat panel displays
   have, since around 2000, become increasingly competitive in
   price and performance.

   (2005-07-28)

   2. A screen multiplexer utility which lets you run multiple
   interactive terminal sessions (and curses programs)
   through a single terminal connection (on one virtual
   console, one terminal, through one modem link, telnet
   session or xterm).

   Screen can detach processes from one terminal and attach them
   to another.  "Auto-detach" lets you continue working after
   being disconnected and reconnected.  It supports keyboard
   driven cut and paste from any text and/or curses application
   (like Lynx) to any other (like xemacs).

   Screen comes with many Linux distributions and is available
   (free) on many other Unix platforms.
