Abstract: An articulated mounting system (100) includes indexed bearings (118) at joints (154, 156, 158) between two members (102a, 102b, 106, 160) that provide stepped rotational movement between the two members (102a, 102b, 106, 160). The indexed bearings (118) are resistant to gravitational slippage. The indexed bearings (118) maintain the position of the joint (154, 156, 158) with tightening the joint (154, 156, 158) and allow for rotational movement of members about the joint (154, 156, 158) without loosening. An adjustable, vertically-oriented, ceiling mount system has leveling mechanism for ensuring that the telescoping tubes are vertically plum. A display mount (300) has handles (310) for allowing adjustment of the position of the mounting system members (102a, 102b, 106, 160) and the angle of display while maintaining a sterile operating field.
