Abstract
Techniques are described that can be used to adjust a refresh rate of a display device. For example, the refresh rate change can be triggered by a user application for a variety of circumstances such as a change in power source from AC to DC or display of 24 frames per second (fps) video. Contents of a primary buffer can be copied to a dummy buffer and a display engine can read video from the dummy buffer to provide video to a display. The clock rate of a clock used to read out pixels can be adjusted using software commands. Video is written to another buffer and during a vertical blanking interval, the display engine reads frames from the another buffer instead of the dummy buffer.
