A stellar 3D Y/C (4 MB, 10-bit) digital comb filter with Vertical Contour Correction provides accurate processing of RF and composite-video signals for a sharp, clean picture. This high-end filter significantly reduces detail noise, seen as shimmering or flickering, in complex or intricately detailed scenes.

The set's HDMI (High-Definition Multimedia Interface) input allows a direct digital connection with a DTV set-top box or receiver. HDMI is a lossless, uncompressed, all-digital audio/video interface to link any audio/video source (such as a set-top box, DVD player, or AV receiver) with your TV or monitor. 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.

DFine high-speed velocity-scan modulation improves contrast and overall picture sharpness by changing the speed of the electron beam as it transitions between bright and dark areas of the picture. Further, the TouchFocus automatic digital convergence system creates perfect corner-to-corner focus at the press of a button. (Manual override adjustments are available.)

For audio, the 46H84 offers SRS WOW, combining SRS 3D (which creates a wide, three-dimensional sound field), TruBass (which boosts bass-frequency perception for more dramatic low-frequency effects), and Focus (which raises the sound image vertically to create clearer voices)--enhancing sound quality through the set's own two speakers (which are powered by five watts per channel).

Built-in lifting handles greatly simplify positioning and, if necessary, repositioning.
