Wall displays require an entire wall to be clear and requires the audience to face the wall for best viewing.

Large wall displays for group viewing in theater auditoriums, recreation rooms, living rooms, classrooms, simulated gun ranges, etc. Small wall displays are used for cubicles, private viewing rooms, computer displays, arcade cabinets, etc.

Large tabletop displays are seen in conference rooms, military command centers, etc. Small tabletop displays are for office desks, research tables, electronic board games, etc.
