When you are geek, difficult to be content with 3 HDMI ports means of a TV. For little more than playing on console, it is the total debacle! With this switch, I could connect all my devices and maintain a free port to connect my PC to the TV. The switch is automatic, and works great for gaming consoles. That's perfect. The unit is a little big, not very aesthetic and difficult to hide in contrast, but it's still a good product that I recommend.
