You can then select the PC running Steam on the main Steam Link dashboard and either press the “A” button on a controller, click “Start Playing” with a mouse, or press Enter on a keyboard. You’ll be prompted to enter a code shown on your TV into Steam on your PC to confirm the pairing process.
The process quick and simple, and involves joining a Wi-Fi network (if you’re not using Ethernet), setting up some basic picture settings, and choosing the PC on your network that’s running Steam.
Use the instructions on your screen to set up your Steam Link and connect to the PC running Steam.
