Remember the Steam Link, the $50 box from Valve that let you stream games from your PC to any TV in your house? The hardware has been discontinued, but Steam Link is still around as an app for iOS, Android, and—perhaps most intriguingly—the Raspberry Pi.
We’ve discussed how to stream games to your phone and tablet with the Steam Link app, and it’s great—you get the mobility of playing anywhere in the house, but your gaming PC does the heavy lifting, sending the video feed to any device on the network. If you want to stream those games to a TV, though, the Raspberry Pi is a perfect, inexpensive solution for doing just that. And if you have a Raspberry Pi running RetroPie, Steam Link is built in as an experimental add-on.
Right Now, Steam Link is only compatible with the Raspberry Pi 3 and above. If you have an Nvidia card in the gaming PC you’re streaming from, though, you can create a very similar experience with Moonlight, an open-source client for Nvidia’s GameStream technology. But for the purposes of this guide, we’ll focus on Steam Link and newer Pi models.
Using Steam Link on the Pi is very similar to its iOS and Android app, with just a tad more setup. Before moving forward, you’ll probably want to check out our guide to getting started with the Raspberry Pi, if you haven’t already—it’ll detail all the hardware you need for this project, as well as the initial setup of Raspbian, the Raspberry Pi’s operating system. Once you’re done with that, you can proceed with the steps below.
