A monitor support comprises: a static arm (16) configured to mount rotatably to a monitor support arm (10) at a lower end and a support arm junction (30) at an upper end; a moving arm (34) pivotally attached to the static arm (16) at the support arm junction (30) with a first pair of one-way freewheel friction hubs (36a, 36b) that includes first and second one-way cam assemblies (70a, 70b, 72a, 72b) and friction disc assemblies coaxially mounted to the support arm junction (30). The moving arm (34) includes monitor mounting structure and preferably includes a second pair of one-way freewheel friction hubs (44a, 44b) coupled to a VESA mounting plate (46) with a quick disconnect assembly. The monitor support and the monitor support arm (10) permit free movement in elevating a mounted monitor and require the application of force exceeding that of the monitor weight to lower a mounted monitor.
