Abstract: A video driving module for multiple monitors and method for the same are proposed. The video driving module has a CRT controller for converting a plurality of image signal into a plurality of digital video signals, and a plurality of converters connected to output the CRT controller and used for converting the digital video signals into a plurality of RGB analog signals. The output of each converter is connected to a monitor for displaying one of the plurality of RGB analog signals. The multiple monitors can be simultaneously displayed and refreshed.

Abstract: A video display system is used to display an image signal on a display unit and a method for power conservation thereof is proposed. The video display system has a CRT controller (CRTC), an image signal generator and a power controller. The CRT controller (CRTC) generates a synchronous timing signal for the display unit and a first mask signal. The image signal generator converts the image signal into a video signal with reference to the synchronous timing signal. The power controller turns off or slows down the image signal generator during an enabling time of the first mask signal, which is either a horizontal blank time or a vertical blank time.
