The Ultra gives you access to over 3,5000+ Roku channels
and is Roku's newest flagship 4K HDR streamer. It comes with all the bells and whistles including Ethernet, Voice Search and a Gaming Remote. Included are both SD and USB ports for extra storage and mkv media playback. Unlike the Roku 4, it's fan-less, is smaller and runs much cooler than it's predecessor. It provides smooth 60FPS playback of HDR 4K UHD and features a lightning quick Quad Core processor.
