You don't need Directv, but you will need some kind of cable or satellite to view non-Roku channels. For whatever is worth, I bought this Sharp Roku TV on 8/22/17 and had to return it yesterday because the picture went black and I could only get audio. Best Buy accepted the return even though the 15 days had expired. I bought a 49" LG instead. It's a bit more expensive, but picture is much better and I don't need two remotes just to change volume or turn TV on and off, as I did with the Sharp.
