The realism of a TV's image is strongly linked to its contrast ratio, and this plasma features a high contrast ratio of up to 10, 000: 1. Such a wide range from black to white means great depth and dimensionality with vibrant colors – and this plasma can display an incredible 29 billion colors for a superior picture. Deep blacks provide excellent shadow detail during dark scenes, while brilliant whites allow Panasonic's plasmas to render bright scenes with vivid realism. Sports, movies, and original network programming are all available in high definition from many local broadcasters. Receive and view local over-the-air broadcasts on this plasma in stunning HDTV clarity using the built-in HDTV tuner. If your cable company passes through HDTV broadcasts from local broadcasters, you can decode and tune those as well. If you have even a moderately complicated home theater setup, you probably have a pile of tangled cables on the floor behind it. Imagine replacing all those cables with a single cable that carries both digital video and audio at the same time. With the new HDMI standard, that's exactly what you get. The HDMI connector on this TV accepts high-quality digital video and audio via the same thin cable, allowing you to run one cable from the source to the TV. This widescreen TV features a width-to-height ratio similar to movie theater screens, providing a theater-like experience at home. View HDTV broadcasts and widescreen DVDs the way they were meant to be seen. The V-Chip allows users to block programming that may be inappropriate for certain viewers. Using program ratings embedded in TV broadcasts, the V-Chip lets parents decide the programming to which their children have access. Blocked program material is accessible only by entering a 4-digit code that parents create. HDTV broadcasts and DVDs offer more detail and better color than analog broadcasts, and it takes a high-resolution display to deliver all that picture information.
