Big-screen high-definition television just got better-looking and more affordable. Toshiba's 51-inch widescreen, HD-ready 51H84 uses a host of Toshiba-exclusive technologies to make the most of your high-end digital and analog source components. The 51H84's exclusive PowerFocus HD lens system was designed specifically for HDTV programming. Most lens systems cannot faithfully reproduce a high-definition signal. PowerFocus HD uses six elements and a quality color-correction system to produce an image that is up to 65 percent sharper than an image produced by standard lens systems. The PowerFocus HD's higher beam current and finer beam spot provide a 30 percent increase in sharpness and a 10 percent increase in brightness over standard CRTs. Toshiba's four-element PowerFocus HC lenses offer 50 percent higher contrast than comparable 5-element lenses, giving you clear, deep, three-dimensional images.
The set's TheaterFine HD super fine-pitch screen uses a .52 mm design to reduce the space between lines on the lenticular screen, thereby sharpening the image. And since not everything you watch will be high-definition in origin (wouldn't that be nice), CrystalScan HDSC upconverts all video signals (including 480i/p) to 1080i HD. This significantly reduces jagged-line artifacts for a smoother, more natural image. (Selectable 540p, for those who want a progressive-scan image from a progressive-scan source, is available through the onscreen menu.) CableClear DNR+ Digital Noise Reduction circuitry--selectable by input--optimizes poor NTSC signals from antenna or cable by eliminating video noise (snow).
Meanwhile, DFine high-speed velocity-scan modulation improves the definition at picture edges, creating sharper images by slowing the CRT (cathode-ray tube) beam's horizontal scanning during demanding work--say, when rendering transitions from light to dark parts of an image--and speeding it up when scanning easily rendered sections, like broad dark areas.
A 3D Y/C (4 MB, 10-bit) digital comb filter with Vertical Contour Correction processes RF and composite-video signals for a sharp, clean picture. This advanced filter significantly reduces detail noise, seen as shimmering or flicker, in complex or intricate scenes. The TouchFocus digital convergence system (which creates perfect corner-to-corner focus at the press of a button) and AccuFocus 56-point manual convergence system let you choose the best calibration method for your system.
The 51H84 is loaded with connections of all stripes, including a HDMI (High-Definition Multimedia Interface) HDTV input, which gives you a pure, uncompressed video connection with your DTV receiver or set-top box (not included). HDMI supports standard-definition (SD), enhanced definition (ED), or high-definition (HD) video, plus multi-channel digital audio--all using a single cable. It transmits all ATSC HDTV standards and supports up to 8-channel digital audio, with bandwidth to spare to accommodate future enhancements and requirements.
For audio, the 51H84 offers SRS WOW, combining SRS 3D (which creates a wide three-dimensional sound field), TruBass (which boosts bass frequency perception for dramatic low-frequency effects), and Focus (which raises the perceived sound image vertically to clarify voices) to greatly enhance your home-theater sound.
The set's cabinet offers lifting handles for ease of delivery and installation.
