An interactive display system is provided including a support frame having a vertical positioning element that counterbalances the weight of an attached interactive display, for example a touch-sensitive display. The support frame optionally includes a power supply increasing the range of mobility of the interactive display system by eliminating the need for power cord and power outlet connections. One exemplary support frame for an interactive display includes a base element, at least one support extending vertically from the base element, and a positioning element housed within the at least one support. The positioning element counterbalances the weight of the interactive display allowing vertical repositioning of the interactive display with a force of less than about 25 pounds.
