The BRAVIA KDS-55A3000 is a discontinued, 55" rear-projection HDTV from Sony. It utilizes the same SXRD technology – three separate panels for red, green, and blue – as Sony's more expensive XRB rear-projection units. In features, the KDS-55A3000 is essentially identical to Sony's 50" KDS-50A3000 ($200 less) and 60" 60A3000 ($200 more). Motionflow 120Hz technology uses real-time calculation to double the number of frames in 60Hz content, while x.v.Color technology enables more accurate color reproduction. The Advanced Iris function aims to improve contrast in varied room lighting conditions. Digital Reality Creation, included in the unit's BRAVIA Engine EX video processor, can upconvert 480i content to HD.
