Key Features of the LG 100QNED86T 100" 4K Smart TV

QNED Color technology delivers a vibrant and accurate palette that makes scenes look more lifelike. Combined with Advanced Local Dimming, the TV manages contrast carefully so bright highlights stay bright and dark areas retain detail rather than washing out.

At the center sits the α8 AI Processor 4K. This processor handles picture and sound optimization automatically, adjusting for different types of content. AI Super Upscaling improves lower-resolution sources in real time, while AI Picture Pro and AI Sound Pro refine both image and audio according to the room and the viewer’s preferences.

The native 120Hz refresh rate supports smooth motion, which is useful for sports and games. Gaming features include FreeSync compatibility, Variable Refresh Rate (VRR), Auto Low Latency Mode (ALLM), and a dedicated Game Optimizer. HDR10 and HLG support, along with FILMMAKER Mode, help preserve the intended look of movies.

webOS 24 provides a clean smart interface with profile options, voice control via the Magic Remote, and regular updates through the webOS Re:New Program. Connectivity includes four HDMI ports that support 4K 120Hz, eARC, VRR, and ALLM, plus dual USB, Wi-Fi 5, Bluetooth 5.1, and Ethernet.

Audio is handled by a 20W 2.0-channel down-firing system enhanced by α8 AI Sound Pro, which can create a virtual 9.1.2 up-mix effect. Clear Voice Pro and AI Acoustic Tuning further improve dialogue clarity and room adaptation.
