Abstract
One embodiment of the present invention sets forth a technique for continuously adjusting a variable refresh rate to reduce the power consumption of a display device. The refresh rate of the display device tracks the effective frame rate of the content being displayed. As the effective frame rate of the content decreases, the refresh rate is lowered until a minimum value is reached. When the effective frame rate of the content equals the refresh rate, the refresh rate is increased until the refresh rate exceeds the effective frame rate of the content or until a maximum value is reached.
