Smart never looked so good. The KS8000 4K SUHD TV features Quantum Dot Color technology, which covers you in our most superior picture yet, immersing you in whatever you’re watching. While HDR 1000 High Dynamic Range uses revolutionary technology to bring out details you’ve never seen in every foreground and background, Peak Illuminator Pro makes shades of every color pop. Plus, its Motion Rate 240 puts you on the pulse of every action sequence, while its flat, virtually bezel-less 360 design exudes elegance from every angle. If that’s not enough, we’ve enhanced its Smart Capabilities with the latest innovations and auto-sensing universal control, so it's insides are as extraordinary as its outsides.
