An apparatus for mounting and arranging a plurality of flat panel video display assemblies. An a arcuate receiver segment has a lower surface for attachment to a support and an upper surface for receiving a connection plate. A connection plate is attached to the bottom of each display assembly. The receiver segment includes a central registration pin about which an edge cutout on the connection plate is aligned. The base plate has two locking tabs in spaced relation on either side of the registration pin. Each display assembly is lowered over and rotated about the registration pin so that opposed edges of the connection plate slide into respective locking relation with the locking tabs. Ten receiver segments are arranged to form a circle for mounting ten video displays. Adjacent display assemblies are fastened together to form a mechanically secure and visually seamless display.
