Feel free to refer me to a previous thread dealing with this or a similar question. The main question/information sought is how do the different "trademarked"/ "exclusive" technologies from the big manufacturers such as Toshiba, Mitsubishi, Sony, Pioneer, ect., compare to one another as far as quality/positive enhancement of picture produced from a standard DVD source? Does one company's technology make greater strides at actually fulfilling their embelished descriptions? This question is assuming all other componets of the test system one theoretically could use to compare and test these different technologies are filtered out of the results. Here's an example from Hitachi's web site: "Highly refined Super Contrast II CRT's produce a brighter, more accurate high definition image". Here's one from Toshiba: "Dynamic Quadruple Focus : Dynamic Quadruple Focus utilizes both horizontal and vertical beam adjustment to ensure that even the edges and corners also have a precise beam spot for a sharp, uniform picture from corner to corner". This is a tricky question to answer and part of the answer is inevitably subjectively based upon who's doing the visual comparison. I guess I'm looking for a scientific (or as close as one can get being outside the R & D of these comapnies) validation of the new technologies developed by the different companies. I want to know if "Company X" is on to something or if they are just using fancy terms to describe a minor upgrade?
