The technology inside all televisions is virtually the same except for the 327 series, which are the only units to feature an AMVP motion processor. Other than that, Mitsubishi DLPs come with a 1280 x 720p Proprietary DLP light engine, PerfectColor, dark detailer, DefinEdgeVSM, 480-line motion-adapter 3D Y/C comb filter, and auto film mode.
In watching all four series at Tweeter, it was difficult to distinguish a difference in picture quality from the Diamond to 327 series. All models exhibited an excellent picture. I watched several programs one of which was a couple sailing on the ocean. Of the picture, I can only describe it by stating it was as if I were standing on the shore and looking out at sea. It looked that real and life-like.
