I went from a 50" to a 55". Could that be it? Overall, the VT30 'smooths' over facial detail. Again that's using THX mode and a sharpness setting of +50.
Component cables on my older set, on good quality HD channels, always provided excellent facial detail. Yes, some channels are better than others which was the case with the PZ800U. Also the digital patchiness in faces was something I never saw on the PZ800U. Is this something unique to HDMI?
