A tilt control for a tiltable mount and a mount including a tilt control are provided. The mount has first and second brackets mounted for rotation or tilting, such as about a shaft. The second bracket might be a monitor mount tiltable relative to an arm bracket. The tilt control includes a friction brake and an over-running clutch configured to disengage the friction brake to permit upward rotation or tilting, but engage the friction brake for controlling the downward rotation or tilting. The friction brake is engaged by the over-running clutch to control downward tilting. The friction brake generates a counter-acting force to retain a mounted device such as a video monitor and/or keyboard in fixed position against drooping, but to permit downward tilting upon application by a user of an adjustment force.
