A:Answer Hello!
A Fire TV Cube is a Fire TV device that would give you access to streaming apps such as Prime Video, Hulu, Sling TV, Netflix and many more. It allows you to only use and subscribe to the channels you want to use. It also has an Echo Dot built into it, so you can control your TV hands free just by asking Alexa. It comes with an IR reader in the box, so it will control devices in your home theater set up that use IR control, such as a gaming console, or cable box, or even some sound bars. So everything can be done with your voice. So, if your TV has an HDMI port and works with apps etc., I'm guessing the cube will work just fine, however, you may not get to take full advantage of what the cube can do for you such as the quality of sound etc. I hope this information helps. Have a great day!
