The Samsung QN65QN70HAFXZA is a 65-inch Neo QLED 4K Smart TV designed to deliver premium Mini LED picture performance, AI-enhanced processing, vibrant Quantum Dot color, and advanced smart entertainment features. Part of Samsung’s 2026 Neo QLED lineup, the QN70H series combines Quantum Mini LED backlighting with Samsung Vision AI and the NQ4 AI Processor to create a brighter, more immersive 4K viewing experience for movies, sports, gaming, and streaming.
