Hey guys check this thing out! The Steam Link seems to be a small computer that you can hook up to your TV through HDMI. It has an Ethernet port so you can use Valve’s in-home streaming without slowdowns (like on WiFi for example). There’s also two USB ports to send input back to the PC you’re streaming from.
