The Steam Link allows existing Steam gamers to expand the range of their current gaming set up via their home network. Just connect your Steam PC or Steam Machine to your home network, plug into a TV, and stream your games to the Link at 1080p. Video and audio data is sent from your computer to the Steam Link, while your controller input is sent back in real time. Virtually every game that your computer runs can be played on your TV. Steam Controller, Xbox One USB wired, Xbox 360 USB wired, Xbox 360 wireless, PS4, PS3 wired and Wii-U Pro controllers are compatible, as are many third-party Xbox controllers. Steam Link's typical price is $50, but right now you can get it on Amazon for just $20. See the significantly discounted Steam Link on Amazon.
