Overview

The LG 70UN7370PUC brings big-screen 4K UHD entertainment to your living room with a 70-inch LED display powered by LG's Quad Core Processor 4K. This processor handles upscaling, noise reduction, and color mapping to deliver a clean, detailed picture from both native 4K and lower-resolution sources. Active HDR support with HDR10 and HLG formats means the TV dynamically adjusts brightness, contrast, and color on a scene-by-scene basis, pulling more detail from highlights and shadows than standard dynamic range content allows.

Where this TV truly stands out is its smart ecosystem integration. Running LG's webOS, it provides fast access to streaming services with a clean, user-friendly interface. The included Magic Remote adds voice commands and motion-based point-and-click navigation, making it far more intuitive than a traditional remote. Built-in Alexa and Google Assistant let you control the TV and compatible smart home devices by voice, while Apple AirPlay 2 and HomeKit support make it a natural fit for Apple households. Connectivity includes Wi-Fi, Bluetooth, Ethernet, USB, and multiple HDMI inputs, covering virtually any source device you need to connect.
