Instructions
Turn off your TV and Xbox 360.
Connect one of the HDMI cables to the HDMI port on the back of your Xbox 360. Plug the other end of the cable into one of the "Input" ports on the IOGEAR switcher.
Plug the other HDMI cable into the "Output" port on the IOGEAR switch, then plug the other end of the cable into an open HDMI port on your TV. Plug the included power cable into the back of the IOGEAR switch and plug the other end into an electrical outlet.
Switch on all of the devices. Use the remote control included with your IOGEAR switch to set it to the correct video port. This will be the port you used to connect your Xbox 360. The ports are labeled 1 through 4, each with a corresponding button on the controller.
