Velocity-scan modulation improves the definition at this set's 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. The GB-4308's 2D Y/C four-line comb filter further enhances resolution by removing blurred edges between colors and reducing dot crawl (tiny, moving dots of color along a sharp color separation in a vertical line, as in a depiction of a character's striped T-shirt).

In the audio department, BBE sound simulates surround sound through two channels, either the set's or an external pair. When listening through external speakers, you can still control the volume right from the remote control after connecting the set's variable audio outputs to an amp or receiver. The set offers two component-video inputs (one for standard component-video, one for progressive-scan), two S-video inputs, one RF input (compatible with antennas and older VCRs), two rear AV inputs, and one set of front AV inputs.
