I created a new thread because the more answers I get to my questions, the more unsure I am about why we got a 4K UHD TV and just ordered Tivo Edge for cable promising 2160K . The max resolution our cable company Comcast offers is 1080p (HD). That means all recordings on Tivo will be not higher than 1080p. Our TV already has streaming channels on it like Netflix, Prime, Hulu which we can see in 2160 UHD quality. The cable company offers a 4K cable box with DVR in case there are some TV channels in future offering 2160p. So why would we need the Tivo Edge? Can anyone point out the benefits for the new Tivo Edge, please before we send it back? Is it the skipping function?
