I haven't gotten that far yet. Missus has this thing about a TV. I suggested using the PC and all her pads/phones, etc. Zero interest.
If your TV has HDMI inputs, you can use a Roku to get Prime TV, Netflix, You Tube TV or Sling. HalfSmokes is right that SmartTVs usually don't work out as well.
Think of the Roku as a unifying "cable box" that you can add services (like the above) to. It works very well. Except it's attached to your internet.
