摘要： A video signal circuit of a notebook computer includes a north bridge chipset, a control module, a VGA port, an A/D converter, a selection module, and a control unit. The north bridge chipset is coupled to the control module and the selection module. The VGA port is coupled between the control module and a display device and a processing device. The A/D converter is coupled between the control module and the selection module. The selection module is coupled to an LCD of the notebook computer. The control unit is coupled to the selection module and the control module. The video signal circuit can be controlled to send a first analog and digital video signals generated by the north bridge chipset to the displaying device and the LCD respectively, or receive a second analog video signal from the processing device and display it on the LCD.
