Valve discontinued the Steam Link hardware device in November 2018, in favor of supporting its software-based Steam Link application for mobile devices and smart televisions, as well as providing Steam Link as a software package for the Raspberry Pi microcomputer. Steam Link was originally released as a hardware device alongside the debut of Steam Machines in November 2015. And remember that an ethernet connection will offer better performance, naturally.Steam Link is a hardware and software product developed by Valve Corporation for streaming Steam content from a personal computer or Steam Machine wirelessly to a mobile device or other monitor. If you own one of Samsung's 4k TVs and want to give the app a try, just download it from Samsung's app store (it's not available to everyone yet) make sure your PC and television are on the same network.
And it's worth remembering this is a beta app, so it should improve and add better wireless controller support with future iterations.
He did discover some issues with the wireless Steam Controller, but found plugging in a wired Xbox 360 controller worked fine. PC Gamer's Wes Fenlon tried out the app and found it to work essentially as well as the Steam Link hardware. It may be limited to 1080p and 60fps, but for just $50 it's a better alternative to one of Valve's own Steam Machines. While it's not always perfect, the Steam Link is one of the best ways to stream PC games to a big screen living room TV using a wired or wireless network. While it was originally assumed Samsung would be integrating the Steam Link hardware inside its new TVs, the use of an app means those who already own its 2016/2017 4K televisions can use the functions.
Now, a beta version of the app has finally arrived. Last October brought news that Samsung would be adding Valve's Steam Link functionality into its high-end televisions, meaning those who wanted to stream their Big Picture PC games straight to another TV wouldn't need the tiny box.
