This is somewhat a re-post of my previous question on a past thread, but since I got no satisfying answer I'll ask it again. I just purchased a Panasonic 42" HDTV Plasma. I am extremely picky with PQ, almost to paranoia levels. A couple of things, first, I noticed a small level of video noise speckle on the black areas (like in the black bars of anamorphic DVDs or dark shadows in the picture, more like dancing speckling sub-pixels). This so called "faint grainy noise" is like a motion of grainy-dancing-speckles only in the very dark areas. These small dancing noise-speckles are of very dark blue and dark red and they appear -uniformly- only on the almost black and very dark hues like the darkest color gradients and deeeeeep dark grays (but not on deep blacks after a re-calibration and using the Panasonic Plasma's 'Dark' Black level setting). And they are only noticeable while looking at the screen a very close distance, one feet to be precise. I initially thought that this was due to my very old DVD player with S-Video interface. I barely calibrated the set using commercial DVDs with the simple and plain THX setup menu (don't own Avia nor DVE, yet). So, anyway, I finally got the DENON 'little hi-end' deck (DVD-2910) and I saw a small but perceived improvement with overall PQ using the progressive component interface. With the DENON I'm getting subtle but better saturation of colors, more natural hues, slightly sharper picture and detailed contrast compared to the very old Pioneer deck. But again this is an unfair comparison, as the Pioneer was using a composite S-Video connection and the DENON a component one (and as with the Pioneer, the de-interlacing is done but the Plasma's built-in circuity and in the case of the DENON a more advance Faroudja DCDi chip is handling the job). I'll get the HDMI cable later but something tells me I won't get any more improvement than what I've got already. But guess what, the "grain-speckle" symptom persists, and this happens on every input used. Why is this? Is it normal with Plasma sets? inherent with the technology? Will it go away with HDMI? Using the same old Pioneer DVD Player with my 10 year old CRT set (and same quality cables) never showed anything remotely similar. Although this 'noise' is very subtle and only noticeable if you look at it one feet from the screen, I'm worried that this might be a defect. Please help me sort this out so I can be sure this is either a defect or if it's normal. Second, there is in fact a greenish bias that cannot be corrected with ease using the basic user's menu settings. Without the proper training and living in South America (Venezuela), where can I contact or have an equivalent service like the Imaging Science Foundation nearby? I corrected it thanks to the DENON's excellent built-in picture settings, but this only works while using this deck, so all other inputs are affected. So, I'm still where I started, no answer on what are those "noise-dancing-speckles" on the close to black areas of the picture (again, only visible at very close range) and no way to calibrate this display to get rid of the greenish bias... unless I find someone capable of poking inside the service menu. *sigh!* Any help would be quite appreciated.
