An adjustable display arm utilizing a single motion, friction-locking hinge mechanism to allow a user to adjust the display height across a range sufficient to accommodate different-sized users while supporting the weight of an attached flat-panel display. The adjustable display arm can comprise a base assembly, an arm assembly, and a mount assembly. The arm assembly can have a lower arm bracket, an upper link, a hinge mechanism connecting the upper link's first end to the lower arm bracket, and an upper arm bracket attached to the upper link's second end. The hinge mechanism can have a shaft, a clutch bearing, and a friction pack. When assembled, the arm assembly's hinge mechanism will provide minimal resistance to a user raising an attached flat-panel display. However, the hinge mechanism's friction pack will provide resistance to the lowering of the arm assembly, thereby supporting the weight of an attached flat-panel display and effectively locking the adjustable display arm in the desired position.
