I see. I'm pretty integrated into Chromecast with google tv device...i'll look in more...we'll see$65 a month, but I think you can still get 2 week trial for free.
I suggest using Firestick or Roku (those are the two I have). I have a chromecast (im my bedroom) but it's the basic external device, not the one built into the tv. So when I use chromecast, you have to cast it from the YouTube TV app on your phone. Not ideal for me.
I suggest buying a 4K Firestick while they're still half price ($25). It's super smooth on there.
