A combination system capable of selectively switching A / V signals supplied from each A / V signal supplying device is provided to control a switch operation only of the combination system without newly setting a connection of an SCART jack cable, thereby selectively supplying A / V signals. An input terminal(210) receives an outer RGB video signal, an outer composite video signal, and an outer audio signal supplied from an outer signal supplying device. A switching portion(240) adaptively selects the received signals, and outputs the selected signals. A selection portion(260a) outputs a reproduction selection signal for one of the first device and the outer signal supplying device. When the reproduction selection signal is applied, a main controller(280) controls the switching portion(240) to adaptively select the signals relative to the selection signal. An output terminal(250) outputs the selected signals to a display device.

The present invention relates to a method of realizing synchronous monitoring on a plurality of VGA sources of a LCD TV; and resolves the technical problem that the LCD TV designed and produced by the method can be simply operated and set to realize the synchronous block-division display and in-phase monitoring of the VGA signal source outputted by a plurality of computers via a TV set. The technical proposal is realized when the TV set has basic configurations including a liquid crystal display, a VGA port and at least two SCART ports with the support of a TV-set central control unit and a management program. The present invention has the advantages that the TV set, which is designed and produced by using the method, can greatly extend the product functionality and effectively save resources without increasing the production cost.
