Abstract: A modular frame for supporting one or more LED panels to form a video wall, a leveling system for the video wall, and a calibration and/or cleaning system for the LED panels of the video wall. The modular frame is a framework comprising at least two support columns, a primary support beam and at least one secondary support beam wherein the at least two support columns are spaced apart with the primary support beam extending substantially laterally thereacross, and a plurality of stiffening elements. The at least one secondary support beam is an articulated support beam for supporting a column of one or more LED panels therefrom and wherein the articulation point of each of the at least one secondary support beams as connected to the primary support beam is substantially centered over or below the center of mass of the one or more LED panels suspended therefrom.
