Abstract: An electronic device and a control method thereof, the electronic device which provides input/output functions of an image signal, the electronic device including: an input signal processor which processes an input image signal input by an external image source; an output signal processor which outputs an output image signal to an external display apparatus; a connector which is connected to the external image source or the external display apparatus; a switching unit which switches on/off a path between the connector and the input signal processor or the output signal processor; and a controller which controls the switching operation of the switching unit based on an information signal input or output through the connector. With this configuration, an electronic device and a control method thereof enables input/output of an image signal to/from an external device through a single connector.

Abstract: A computer system including a graphic chipset generating RGB signals characterizing RGB components, and an output port through which the RGB signals are transmitted from the graphic chipset to a display device, further including an EMI filter to filter EMI from the RGB signals generated by the graphic chipset, and to transmit the filtered RGB signals to the output port; a definition improver to adjust an output level of the RGB signals generated by the graphic chipset to a predetermined output level, and to transmit the adjusted RGB signal to the output port; and a selection switch to selectively connect an output terminal of the graphic chipset with the EMI filter or the definition improver.
