Alpha 7 AI Processor Meets Nano Detail Enhancement
The LG Nano 4K UHD AI NU84 Smart TV 2026 delivers a refined 4K viewing experience powered by advanced AI image processing and Nano Detail Enhancer technology. This high-precision display architecture reproduces deeper contrast, sharper textures, and more realistic color accuracy, while HDR10 Pro with Dynamic Tone Mapping optimizes brightness and shadow detail frame by frame across different types of content.
The Alpha 7 AI Processor 4K Gen9 intelligently analyzes and upscales content toward near-4K quality through 4K Super Upscaling, refining picture quality whether streaming, watching sports, or gaming. Running on webOS 26 with AI Hub, the NU84 brings personalized recommendations, voice control, and multi-AI search powered by Google Gemini and Microsoft Copilot, all protected by LG Shield Security.
Gaming features include VRR, ALLM, HGiG Mode, and Game Optimizer for smoother gameplay, while a 2.0-channel 20W speaker system with AI Sound Pro and Clear Voice Pro delivers clear, well-rounded audio. Connectivity covers Wi-Fi 5, Bluetooth 5.3, 3 HDMI ports (with eARC and ALLM), USB, and Ethernet, all wrapped in a modern Linear Flow Design.
