Abstract: A display system includes a source device that outputs image-data and a sink device that performs a displaying operation based on the image-data. The sink device changes a frame-rate of a panel driving frame as the source device changes a frame-rate of an image frame.

The sink device moves the input starting point to a second clock cycle starting point, at which a second clock cycle following the first clock cycle starts, and sets the second clock cycle starting point as the scan starting point when the first clock cycle starting point is inconsistent with the input starting point.
