    My Sony 1040 receiver supposedly upscales video to 4k. Now...my Premeire is set to 1080i thru component cables into my Sony and on to my Samsung 4k. The tv show 3840x2160 which is indeed 4k. My Roamio and the same Premeire are connected by hdmi and go into the Sony. TV says 1920x1080 for both those boxes. Why would component get upscaled higher than the hdmi. I know the Sony wont upscale 1080p which is why all are 1080i. It may be the fact that the component signal is analog while the hdmis are digital.
