Think of Steam Link, the 50-dollar box from Valve that lets you play games from your PC to any TV Can you stream your home? The hardware has been discontinued, but Steam Link is still available as an app for iOS, Android and ̵
We discussed how you can use Steam Link to stream games to your phone and tablet App, and it's great – you can play mobile anywhere in the house, but your gaming PC is very stressful and sends the video feed to every device on the network. But if you want to stream those games to a TV, the Raspberry Pi is a perfect, cost-effective way to do just that. If RetroPie is running on a raspberry pi, Steam Link is integrated as an experimental add-on.
Steam Link is currently only compatible with the Raspberry Pi 3 and higher. If you have an Nvidia card in the gaming PC you're streaming from, Moonlight, an open source client for Nvidia's GameStream technology, gives you a very similar experience. For the purposes of this guide, however, we will focus on Steam Link and newer Pi models.
The use of Steam Link on the Pi is similar to the iOS and Android app with only slightly more setup. Before proceeding, if you have not already done so, look in our Getting Started Guide for the Raspberry Pi. There you will find all of the hardware required for this project, as well as initial configuration information for Raspbian, the Raspberry Pi operating system. Once you have finished, you can continue with the following steps.
