Variable pixel rate video output and display techniques for computing systems and user devices are presented herein. In one example, a method of providing video data for display on a display device includes determining logical pixels with variable sizing that each represent one or more source pixels comprising at least a portion of a video frame. The method also includes producing metadata describing the variable sizing for the logical pixels, and transferring the metadata with data representing the logical pixels over a display interface for display of at least the portion of the video frame on the display device that maps the logical pixels across target pixels of the display device.
