Advanced iris function enables the projector to dynamically adjust the video image according to the level of the input signal. This results in high contrast ratio of up to 6000:1, along with reproduction of the most subtle details. The HS51 also incorporates three proprietary 720p LCD panels that provide 2,764,800 pixel resolution (1280x720) optimized for HD video input.
