Abstract: The present invention may be used for attachment to a vertical structural element such as a building wall for support of an electronic display. A wall mount frame may have two wall mount brackets spaced apart, slidably disposed and fixedly attachable on two horizontal adjustment bars inserted in two bar apertures in each of the wall mount brackets. There may be an articulating arm assembly rotatably attached at a first extension arm by a wall mount hinge to the two horizontal adjustment bars. An equipment attachment frame may be rotatably attached to a second extension arm of the articulating arm assembly by a frame hinge.
