Three numbers decide whether an arm will work: the VESA hole pattern on the back of the screen, the weight the arm is rated to carry, and the thickness of the desk edge a clamp has to grip. A screen at the bottom of an arm's weight range will drift upward and one over the top will sag. Grommet mounts suit desks with a cable hole. See monitor accessories and arms and stands.
