Steam Link

Steam Link is the small living-room bridge for people who want to play PC games on a TV without hauling the tower over there. By our assessment, its best trick is simple local streaming from a Windows, Mac, or Linux machine to a phone, tablet, or Steam Link box, with controller support doing most of the work. The trade-off is just as plain: it depends on a solid home network, so lag and compression artifacts show up fast when the connection is weak. In practice it feels like a convenience layer over a proper gaming PC, not a replacement for one, and setup is more fiddly than plugging a console into HDMI. Compared with cloud gaming, it keeps the game on your own hardware, which is the whole point. It makes sense for Steam users who already own the games and want couch play without moving rooms. If your network is poor or your PC is far away, the whole thing loses its edge.
