My Qualia uses 12 bit processing, but, this is still a major problem when the source itself, particularly my cable feed, is limited in quality. I suspect that the fact that it is very noticeable on my set is the product of a very large image (I do sit a bit close) and a lot of "detail" of what is essentially noise (the set has a true 1920 x 1080 resolution capability).I don't know why, but Sony also chose not to offer any inputs capable of accepting 1920 x 1080p, which is the native resolution of the set. I am looking into external processors and scalers (Algolith Mosquito and Dragonfly), and it would have been nice to bypass the Qualias scaler completely by going 1080p 60.

You may want to get the display checked out, just to be safe. Rich Harkness wrote a rather long and detailed review of a Sony Qualia 70" model in the Plasma and Flat Panel LCD Displays section of AVS Forum. He did not give the impression that the Sony had any problems with SD signals or false contouring. At least not anything that stood out in his comparison of the display to the 65" Panasonic plasma. If your Sony does indeed use 12-bit processing, noise and false contouring should be nearly eliminated.Many manufacturers have been remiss about 1080p input and it's a mistake. Sony's excuse was that it had to do with copy protection. What? Who did they think they were kidding? The HDCP encryption process has nothing to do with the resolution of the signal. Absolutely nothing: what a joke. Other manufacturers' main excuse was that there is no 1080p content. Seems rather retarded, as 1080p content will be available with the next gen discs in about 6 months. They're selling sets that will be obsolete very shortly in the sense that they will not be able to take full advantage of what the next gen format will offer. Or maybe it's just that they want to offer "new and improved" displays for people to buy in about 6 months (just look at those silly DLP 960x1080 MMDs being sold -- still called "1080p" displays -- that will shortly be replaced by TI's new DLP 1920x1080 MMDs)? Or maybe they didn't want to up the $3 additional cost for the HDMI receiver chip that accepts 1080p? Whatever. I wouldn't buy a 1920x1080 display that didn't accept a 1080p signal via a digital (HDMI and/or DVI) input.
