PROBLEM TO BE SOLVED: To make it possible to display a single video signal on plural display devices at the same time without using an external distributor by arranging a function for distributing the video signal in the display device. SOLUTION: A 1st display device A1 is connected with a personal computer main body D via a video cable C. In the case of making plural display devices display the same picture at the same time, a 2nd display device A2 is connected to a video signal output port F of the 1st display device A1 by using a cable C. A 3rd one and thereafter are connected in the same way. A video signal outputted from the personal computer D is firstly distributed to two lines by a video signal distributing circuit in the display device A1. The distributed video signals are made to a display signal line and a distributing signal line, and the display signal line connects to a display circuit, and a picture is displayed on CRTs. On the other hand, the distributing signal line connects to a signal amplifier circuit, and connects to video signal output ports F via the amplified signal line of the non-attenuated video signal.
