We would like to introduce the new BenQ W500 Home Theater Projector. With the W500 you will recieve the very best video experience with features like an iris-like lens. The technology mimics the human eye by adjusting the aperture after analyzing the incoming video signals. In dark scenes, the aperture contracts for truer black tones; in bright scenes the aperture is enlarged to maximize light output and enable a wider dynamic range, resulting in the best veiwing experience. Enjoy watching your favorite flicks with an amazing 1280 x 720 resolution, 5000:1 contrast ratio in 16.7 million colors.
