Overview

The LG 37LH40 is a 37-inch LCD HDTV that delivers Full HD 1920x1080 resolution, providing sharp detail and vibrant color across its screen. One of its key features is TruMotion 120Hz technology, which processes images at 120 frames per second to virtually eliminate motion blur — a notable advantage when watching sports, action films, or playing games. The set also includes Intelligent Sensor Technology, which reads the ambient light and color temperature of your room and automatically adjusts the picture for optimal viewing without requiring manual tweaking.

Connectivity is a strong point with four HDMI inputs, giving you plenty of room to hook up gaming consoles, media players, and other devices simultaneously. The Invisible Speaker System, paired with SRS TruSurround XT audio processing, delivers surprisingly full sound from a sleek, hidden speaker design. Additional features include Picture Wizard for guided image calibration, Clear Voice II for enhanced dialogue clarity, and ISFccc readiness for professional-grade calibration. With Energy Star compliance and a glossy black finish, the 37LH40 is a functional, well-equipped HDTV suited for bedrooms, offices, or smaller living spaces.
