Equipped with a typical side-and-rear input panel layout, the 47LG90 provides a total of four HDMI ports (one side), two component video inputs, VGA, and an RF input. Unusual for HDTVs, the 47LG90′s audio outputs include both optical and coaxial digital connections. Rarer still was the TV’s ability to pass 5.1 Dolby Digital audio from all connected sources to a compatible A/V receiver—the Samsung LN46A850′s optical audio output would pass multi-channel audio only from programming received via its broadcast TV tuner. The 47LG90 also features a serial control port for use with home theater automation products, and a side-mounted USB port is compatible with flash storage devices containing MP3 and JPEG multimedia files.

First off, it’s worth noting that each of the three sets use a technology colloquially called “local dimming,” where the individual LEDs behind the screen can be dimmed or turned off as needed. It’s this technology that adds some weight to each company’s claim of a 1,000,000:1 contrast ratio (a nice round number, no?) When part of the screen goes dark and another is bright, standard fluorescent LCD backlights must rely on the LCD panel itself to block out the light and create dark areas. The result is the less-than-stellar black-level performance for which many LCDs have been noted.

LG’s 2008 line of TVs include a unique invisible speaker system, tuned by renowned audio expert, Mr. Mark Levinson. Speakers are embedded in strategic spots behind the front cabinet and use minute vibrations to turn the entire front bezel into the speaker system. The result is a clean, polished look, and enhanced audio by increasing the “sweet spot”, giving a wider and richer sound field.
Clear Voice Technology automatically enhances and amplifies the sound of human voice frequency range to help keep dialogue audible when background noise swells.
