A head mounted display includes a head suspension apparatus and a display coupled thereto. In a stationary state, the display is maintained in a desired position relative to the head suspension apparatus. Further, in a release state, the display is always freely movable both vertically and horizontally relative to the head suspension apparatus. In addition, the display may also always be freely rotatable about an axis of the display as well as vertically and horizontally. The coupling of the display to the head suspension apparatus may be attained using a slide bar and hinge mechanism that forms a rigid triangular structure when the display is in the stationary state. Further, the head suspension apparatus may include an adjustable temporal support element for positioning about the circumference of a user's head and an adjustable crown support connected to the temporal support with the crown support including channels for allowing electrical connection lines to move freely therein.
