In certain situations large LCD/LED flat panel displays may either be
more suitable as the primary display or used in conjunction with the
data/video projector to provide secondary displays for those seating
positions that cannot easily view the main display.
These displays should be mounted in such a way that their
connections and power supply are inaccessible to end users. The
aspect ratio and display resolution of flat panel displays should
match the aspect ratio of the computer monitor and projector image
(if a projector is included in the space).
