All my flat panel TVs have Roku 3 boxes (I don't see the need for 4K video since most of my content isn't 4K). I took a 2010 15" MacBook running 3 versions of OSX behind Seira and that runs Plex Media Server. This setup gives us easy access to Netflix, Amazon Prime as well as local content sourced from DVDs we own. Plex also lets us share videos created from our phones as well but that's probably its weakest feature.
