A:AnswerYes. I have Xfinity/Comcast. I have one tv that I use the Roku on. I get everything on that tv that I get on my main tv that's connected to Xfinity cable. As long as your wifi is strong enough to send a signal that the Roku can pick up. It works great for me.
A:AnswerAll depends on the size of the frame around the TV. I also do not know if your TV is wall mounted or not, so I will just give a general suggestion. The Roku itself is pretty light so think about attaching it to the frame with double face tape. Then the wires can be run behind the TV. 3M makes a good product to use for this. Just make sure the front of the Roku is facing out. Should work nicely if wall mounted.
A:AnswerDepends, It's not a TV or Antenna so really you only get what's being streamed. You would probably need a subscription to some to see them live.
A:AnswerRoku requires a credit card before it activates your service. I refused to give this information so I can't use it.
Therefore, I'm returning it.
There is no reason Roku needs this info from me. I don't rent movies or buy anything using Roku never have, never will.
A:AnswerYes --- it works on any SMART TV but does not have to be a 4K. Just make sure to use the right HDMI cable and plug it into the appropriate port.
