Aspects of the present invention provide a display support arm assembly that includes a proximal housing supporting at least one proximal shaft, a distal housing spaced from the proximal housing and supporting at least one distal shaft, and at least one link extending from the at least one proximal shaft to the at least one distal shaft. The at least one link is coupled for pivotal movement about an axis of the at least one proximal shaft. The display support assembly also includes a gas strut extending between the proximal housing and the distal housing. The gas strut provides substantially constant force throughout a range of the vertical adjustment of the display support arm. The display support assembly further includes at least one torque element associated with either or both of the at least one proximal shaft and the at least one distal shaft. The at least one torque element providing force throughout the range of the vertical adjustment of the display support arm, wherein the force is adjustable by adding or subtracting the number of the at least one torque element.
