PROBLEM TO BE SOLVED: To provide a KVM (Keyboard/Video/Mouse) switching device disposed between a plurality of computers and an input/output device including a display, a mouse, and a keyboard shared with the plurality of computers, switching connection between the input/output device and one computer that is an operation target, receiving a switching instruction from a remote controller through the display, and performing switching operation. SOLUTION: This KVM switching device 1 includes a video signal switching circuit 4, a keyboard/mouse switching circuit 108, and a microcontroller 3. The display 2 adapts to the HDMI-CEC (High Definition MultimediaInterface-Consumer Electronics Control) standard and includes: a means receiving a command from the remote controller 10; and a means transmitting the received command to the microcontroller 3 as a CEC signal 9. The microcontroller 3 outputs a switching instruction signal of a connection target computer 101 to the keyboard/mouse switching circuit 108 and the video signal switching circuit 4 when receiving the CEC signal.
