Overview

The LG 50UM7300AUE is a 50-inch 4K Ultra HD LED smart TV that brings together sharp resolution, HDR support, and a full-featured smart platform in a mid-range package. With four times the pixel count of Full HD, the 4K display renders fine details and textures with clarity, while LG's 4K Upscaler enhances lower-resolution content to approach native 4K quality. Active HDR technology supports both HDR10 and HLG formats, applying advanced tone mapping on a scene-by-scene basis to optimize brightness, contrast, and color for each moment of content. TruMotion 120 processing works on top of the 60Hz native panel to reduce motion blur during fast-paced scenes, making sports broadcasts and action sequences appear smoother and more defined.

LG's webOS smart platform provides a clean, responsive interface for accessing popular streaming services, and the LG Channel Plus app opens up more than 70 free premium Internet channels. Built-in Wi-Fi and Bluetooth connectivity allow for wireless streaming and easy pairing with headphones, soundbars, and other Bluetooth-enabled devices. The included remote supports voice commands for searching content, controlling playback, and managing compatible smart home devices like lights and thermostats — no separate voice assistant hardware is required. On the connectivity front, three HDMI inputs and two USB ports accommodate a range of peripherals including gaming consoles, Blu-ray players, and external storage drives, making the 50UM7300AUE a versatile hub for home entertainment.
