A:Answer You should be able to use an HDMI Switcher (RocketFish makes a 4 port switcher) to accomplish this. Simply plug an HDMI cable into the INPUT on the switcher and to your HDMI port on your tv. Then, hook up all your other devices to the switch. It comes with a remote control so you can easily switch between devices. I have my x-box one, x-box 360, WiiU, and DVD player hooked up and it works great.
Hope this helps!
