Abstract: PROBLEM TO BE SOLVED: To attain easiness of extension by enabling many display devices to be chainingly connected in a state of which physical restrictions from respective devices are eliminated without changing the hardware of a system side. SOLUTION: This system is provided with a display driving device 1 outputting a video signal which is to be displayed with respect display areas and a chained display signal which is to be added to the video signal and also which uses at least the timing of one line, a first display device 2(1) capable of displaying a video with respect the display area of itself based on the video signal by inputting the video signal and the chained display signal and also by analyzing the chained display signal while being connected to the device 1 and a second display device 2(2) capable of displaying the video with respect to the display area of itself based on the video signal by inputting the video signal and the chained display signal and also by analyzing the chained display signal while being connected to the first display device 2(1).
