My husband has a question about streaming and I didn't want to start a new thread sorry! We just got a 4K TV and have the Roamio We got a Vizio smart cast so we can watch Netflix and YouTube etc. through the TV but if we were to choose a 4K show through Netflix on Tivo and since it's streaming to the 4K TV would it be in 4K? I know we just have to change inputs from the smart cast home to Tivo input but he didn't know if their would be any difference streaming from the Tivo. I guess we can try to watch a show both ways and see but it's probably a little faster on our new TV I don't know. We're also just using the same HDMI we used with our old Non 4K Vizio to the Tivo but now that we have a 4K TV do we need the high speed 2.0 HDMI connected to the Tivo to make it even better? One person said yes and another said no just curious!
