[QUOTE="knutinh, post: 95749, member: 14776"] I have read a BBC paper that basically says that : 1. The typical english viewer watch tv at 2.7 meters distance 2. That distance is not likely to change unless they break any walls 3. At that distance youll need 53 inches or more to tell the difference between 1080p and 720p under ideal conditions with any significance. [url]http://www.avforums.com/forums/showpost.php?p=3414608&postcount=148[/url] [i]"The Philips does not downconvert to 540p - thats a fact. Neither did last years 37PF9830 (the previous generation 9986 did though). It properly de-interlaces (i.e. motion adaptive) 1080i to 1080p (the subject has been covered in past articles). The 37PF9731 also does 1:1 pixel mapping over HDMI (although I suspect by mistake!!) when fed with 1080i."[/i] I think there is a misconception of what 1:1 pixel means here, but basically it seems that the tv will do 1080@30p with no scaling or overscan if buried in a 60i stream. I would have preferred to reserve the term "1:1 pixel" to truely progressively encoded frames (so as to exclude badly implemented interlacers/deinterlacers) at 60fps or more. Pioneer plasmas have very good video quality and will do IVTC and 3:3 pulldown of 24p material (movies) that are encoded as 60i into a visual 72p. Even though they are typically non-square pixels and only 1024x768 resolution, I think that they give some of the better video images out there, and that is what counts, isnt it? [/QUOTE]
