A tilting support for a display includes a screw that transmits a tilting force between a lower base and an upper support that is pivotally connected to the lower base and carries the display tube. The lower end of the screw is connected to the lower base by a nut that is turned by a thumb wheel that is rotatably mounted on the lower base. The upper end of the screw is hinged to the upper support so that the screw does not turn with the thumb wheel but is raised or lowered as the thumb wheel is turned. The hinge between the screw and the upper tilting carriage permits the change in the angle between the screw and the upper support when the display is tilted through a range of positions.
