Got a Samsung TV from 2016 or 2017? Good news: you can now stream Steam games direct through the TV, without having to have a second PC or Steam Link connected.
A Steam Link app has been released for Samsung 2016 and 2017 TVs through their Smart Hub app store. You'll need to update your TV firmware as well, but once you've done that you can download the app and start streaming games from your laptop or gaming PC.
Small piece of advice: you'll want to make sure your Samsung TV is connected via ethernet. Ethernet connections are best for Steam's streaming service anyway, but that's especially the case given that TVs don't tend to have the strongest wireless receivers in them. (You might get away with it just fine, but it's worth knowing beforehand.)
Steam also announced through their In-Home Streaming group that only four controllers are supported right now:
• Steam Controller • Xbox 360 wired and wireless • Xbox One wired • Logitech F510/F710
It's a bit weird that the PS4 controller isn't supported, given the native support added into Steam last year. But more controllers will be added in due course.
Nonetheless, it's a handy little feature people Samsung owners might not have expected, especially if you bought your TV last year. Being able to stream something like the Jackbox packs directly to the TV, or something like The Witcher is a neat bonus to have. You could probably stream Battlegrounds and play it with the Steam Controller as well, if you're brave.
