An arm supporting a computer video monitor on an ordinary desk or table and allowing the monitor to be moved into different orientations, comprising

• a computer video monitor, and
• an arm supporting said computer video monitor, said arm comprising
• an arm member having a base end and a monitor end,
• a base adapted to be detachably secured to the ordinary desk or table,
• a first rotatable joint rotatably connecting said base to said base end of said arm member, for permitting rotation of said arm member with respect to the desk or table, said first rotatable joint being adapted to permit rotation about vertical and horizontal axes,
• a friction member associated with said first rotatable joint to cause friction in the rotation about the horizontal axis of said first rotatable joint,
• a counterbalance attached to said arm member to support the weight of the monitor and to interact with said friction member to cause the supported monitor to stay in any desired one of a plurality of vertical positions above the desk or table, while also allowing the monitor to be moved easily by hand among said plurality of vertical positions, and
• a second rotatable joint at said monitor end of said arm member for permitting rotation of the supported monitor with respect to said arm member, said second rotatable joint being adapted to permit rotation of said monitor about vertical and horizontal axes to permit said monitor to be rotated relative to said arm member into any desired one of a plurality of positions and remain in said desired position.
