Abstract
A method and system are implemented to dynamically control a display refresh rate. Specifically, one embodiment of the present invention sets forth a method, which comprises the steps of driving a display device at a first refresh rate over a period of time, measuring a number of first content frames with changes in content out of a plurality of content frames that are generated over the period of time for the display device, and driving the display device at a second refresh rate if the number of the first content frames meets a first condition associated with a first threshold reference, and optionally driving the display device at a third refresh rate if the number of first content frames meets a second condition associated with a second threshold reference.
