The new PT-AE900U is a native high definition home theater projector that produces stunning, film-like images with a dramatic 5500:1 contrast ratio. Capable of displaying ultra sharp, ultra clear HD pictures up to 14.5 feet wide, the PT-AE900U is equipped with advanced digital picture enhancing features allowing you to enjoy "Hollywood picture quality" in the comfort of your own home. The PT-AE900U offers a host of image optimizing features including a new Dynamic Iris optical system that extends the iris range by 30% for a breathtaking 5000:1 contrast ratio. Dynamic Iris, with scene tracking capability, constantly adjusts the light volume and gamma curve in real time, so the picture is always optimal and transitions between scenes are amazingly smooth and natural. The PT-AE900U is also outfitted with new Smooth Screen technology that effectively eliminates the "screen door effect" (visible spacing between pixels) and gives the projector a sharp, detailed HD picture that is remarkably smooth. For a high quality, HDTV compatible projector that is as impressive as it is cost effective, choose the PT-AE900U by Panasonic.
