Abstract
One embodiment of the present disclosure describes an electronic display. The electronic display includes a display driver that write image frames to pixels of the electronic display with a first refresh rate or a second refresh rate, in which the second refresh rate is less than the first refresh rate. Additionally, the electronic display includes a timing controller that receives image frames from an image source, in which one or more of the image frames are configured to be displayed on the display panel to play video content; determines a capture rate of the video content based at least in part on a cadence with which the image frames are received, in which the capture rate describes a rate at which each of the one or more image frames was captured by an image sensor; and instructs the display driver to write the one or more of the image frames at the second refresh when the second refresh rate is an integer multiple of the capture rate.
