Samsung's Smart View app, which is available on Android, iOS and Windows PCs, allows owners of compatible televisions to share pictures, video and music content from their mobile device to the big screen. The app itself is available on select Samsung Smart TVs and is in beta with the full release scheduled for early 2016.
It's interesting to see Samsung expand said support beyond the company's own Galaxy brand, not to mention outside the Android ecosystem. A wide range of TVs from 2011 onwards will work with the app, as well as new SUHD units set for release next year. All you'll need to have is the Wi-Fi connection details at hand to ensure your mobile device (or Windows PC) and TV are on the same network.
If you're interested in leaving some feedback for Samsung to take away and improve the app, there's an online form available for exactly that. We highly recommend you check Samsung's official website for more details on what sets support Smart View.
