Overview

The LG 42LH50 is a 42-inch Full HD LCD television that combines 1920x1080 resolution with LG's TruMotion 120Hz technology to deliver a clear, smooth picture. The 70,000:1 contrast ratio helps produce well-defined dark scenes, and the Intelligent Sensor feature automatically adjusts brightness and picture settings based on ambient room lighting, reducing the need for manual calibration. Four HDMI inputs make it easy to connect a range of devices—game consoles, media players, Blu-ray drives—without constantly swapping cables.

The TV includes LG's NetCast Entertainment Access, which provides built-in internet streaming capability directly from the remote. Audio is handled by an Invisible Speaker System with SRS TruSurround XT processing, designed to produce a wider soundstage from the slim cabinet. The built-in ATSC/NTSC/Clear QAM tuner allows for over-the-air and unencrypted cable reception without additional hardware. While this is an older model and its smart features may be limited compared to current platforms, the core display quality and connectivity still serve well as a secondary display or budget option.
