Timing controller for graphics system

Abstract

One embodiment takes the form of an apparatus for changing a frequency of an image data stream, including: a timing controller; a buffer operably connected to the timing controller; wherein the buffer accepts the image data stream at a first frequency; the buffer transmits the image data stream to the timing controller; and the timing controller outputs the image data stream at a second frequency that is lower than the first frequency. In such an embodiment, the image data stream may include a blanking interval; and a data portion; wherein the buffer removes or reduces the blanking interval from the image data stream; and the buffer adjusts the frequency of the data portion such that the data portion and reduced blanking interval occupy a time equal to that of the blanking interval plus the data portion prior to adjustment.
