Using a sophisticated algorithm, the LG processes picture quality elements including brightness, contrast, color, sharpness and white balance. The result is a picture optimized for it's surroundings, more pleasing to watch and which can also save up to 50% in power consumption.The AV Mode optimizes the picture into Cinema, Sports, and game Mode according to the video and audio content. The viewer has the ability to quickly choose the correct mode for the picture they are viewing.Automatically enhances and amplifies the sound of human voice frequency range to help keep dialog audible when background noise swells.This TV contains the detailed calibrations necessary for professional certification by the Imaging Science Foundation. The resulting ISF "day" and "night" modes will then be accessible by the user to experience the best their LG HDTV has to offer.

Screen size: This flat-panel LCD television has a 42” screen, measured diagonally from corner to corner. This screen size is perfect for viewing from 5.9’ to 11.8’ away.

Resolution: A 1080p resolution means that this television has 1080 rows of pixels vertically. The more pixels a TV has, the clearer the images it can produce. The p stands for progressive scan, which means the TV refreshes every row of pixels during each cycle to produce smoother motion and sharper picture than interlaced scan.

QAM tuner: The QAM tuner gives this TV the capability to receive free in-the-clear digital programming.

Aspect ratio: A width to height pixel ratio of 16:9 means this TV has a widescreen aspect ratio, which accurately recreates the dimensions in which HD programming and many feature films are shot.

TruSurround XT also lifts dialogue out of the chaos of sound and provides deep bass.
