Abstract
A display controller, video signal transmitting method and system thereof are provided. The display controller includes a processing circuit; a transmitting channel, coupled to the processing circuit; a receiving channel, coupled to the processing circuit; and a clock generator, that generates an internal clock signal and an external clock signal. Upon receiving a video signal, the processing circuit processes a first partial pixel data of the video signal to output a first display control signal. The transmitting channel converts a second partial pixel data of the video signal to a partial video signal having a multiple data rate according to the internal clock signal to be outputted.
