Advertisements New 4K TV (Sony XBR65X850C) hooked up yesterday. I know the best my Roamio can output is 1080 on my HDMI cable and my TV should 'upscale' it to 4K. I have a few questions for anyone that has the same/similar combination. 1. If I watch a Netflix 4K show from my Roamio, I'm limited to the 1080 output to my TV, based on Roamio's hardware, right? 2. But, if I watch a Netflix 4K show from my Sony TV and wired internet connection then I should be displaying 4K, correct? 3. Can't find it in the TV manual about up-scaling. Is this typically a feature that one has to 'turn-on' or is it likely that my TV is already up-scaling from my Tivo via my HDMI connection? 4. I think I have a version 1.4 HDMI cable. Should I invest in a 2.x HDMI cable instead? Any help/answers are appreciated.
