If it's the "blacker than black" and "whiter than white" issuse Audioholics referenced in your post above, I'm not sure that would result in a "washed out" picture, since I'm pretty confident no one broadcasts any highlight information above 235. And as far as loss of shadow detail in the 0-16 range, without a test pattern to view, I'm not sure any D* channels broadcast data in that range either. Blu-ray is a different story. When I AB'd my HR24 (connected to HDMI2) with my HR20 (connected to HDMI1), I just had to tweak brightness and contrast slightly on that input to make the two pictures virtually indistinguishable. I guess since you're using your Denon to switch, you need to find a "one size fits all" brightness/contrast setting for anything connected to the Denon. That's why I don't like using a receiver to switch between video inputs. I'm a PQ fanatic who calibrates his own displays, so I like to be able to tweak each input source differently, if need be.
