Overview

The LG 47LD520 is a 47-inch class LCD HDTV built around a 1920x1080 Full HD panel that delivers solid picture quality for everyday viewing. Its standout feature is TruMotion 120Hz processing, which smooths out motion artifacts during fast-paced content — a noticeable benefit when watching sports, action films, or gaming. The 100,000:1 dynamic contrast ratio enables the TV to produce deep blacks and bright highlights, while the Intelligent Sensor reads ambient light in the room and automatically adjusts picture settings to maintain optimal image quality without manual tweaking.

Connectivity includes three HDMI 1.3 inputs, component and composite video inputs, and a USB port for media playback, giving you flexibility to connect multiple source devices. The built-in 20-watt audio system features a 2-way, 4-speaker configuration with Dolby Digital decoding and LG's Infinite Sound surround processing, producing fuller sound than many flat-panel TVs manage on their own. With built-in ATSC, NTSC, and Clear QAM tuners, the 47LD520 can receive over-the-air and unencrypted cable signals directly. While it lacks smart TV features and LED backlighting found in newer models, the 47LD520 delivers dependable 1080p performance at a large screen size for those who use external streaming devices or simply want a reliable broadcast and movie-watching display.
