You would think so. I asked this same question about DVD players that use Faroudja technology. Saying they convert SD DVDs to 1080p which is HiDef. But people say the clarity is in the way they format the Dvd when being made. Seems like 1080p would be 1080p. I do know they use HiDef cameras for HiDef broadcasts. So if it were as easy as a video upscaler,studios would save their money and just tell us to buy an upscaler. Make sense?
I'm sure it improves the quality of the picture some but since not starting as an HD signal just how good can it get? Be it DVD or Tv. They(Cnet and other electronic guides)say you can barely decern HD from upconversion from normal viewing distances around 2.5 to 3 times diagonal screen. Yes you can if you hit pause and study the freeze frame or close enough to count pixels I guess. So that should have answered you question. One thing it should do is prevent signal degradation because it's not just passing trough. Everytime you have a connector you're loosing some signal.
I see alot about the video upscaling on this reciever but im still a little unclear. Does this actually make standard def tv look like hi def?
