Embodiments provide a tilt mechanism for tilting an electronic display that includes at least two nested torsion springs to offset and/or balance the torque generated by a display acting on the tilt mechanism. In some cases a tilt mechanism includes first and second brackets pivotally coupled about a tilt axis. First and second springs are wound about a tilt axis such that the first spring is located at least partially within the second spring. The springs engage with the brackets to exert first and second torques between the first and the second brackets. In some cases such tilt mechanisms can be carried by stands, arms, carts, and the like. Methods of tilting electronic displays are also provided.
