  • 4K HDR processor X1™
    Our powerful processor uses advanced algorithms to cut noise and boost detail. With an even clearer 4K signal, everything you watch is closer to 4K resolution, full of lifelike color and contrast.
    Our TVs with a wide color gamut and unique TRILUMINOS PRO™ algorithm can detect color from saturation, hue, and brightness to reproduce natural shades in every detail. You’ll enjoy colors that are closer to those seen in the real world.
  • Object-based HDR remaster
    With an Object-based HDR remaster, the color in individual objects on-screen is analyzed and the contrast adjusted, unlike most TVs where contrast is only adjusted along one black-to-white contrast curve. Because objects are remastered individually, this TV can reproduce greater depth, textures, and more realistic pictures.
  • 4K X-Reality™ PRO
    See glorious 4K pictures, rich with real-world detail and texture, exclusively powered by our 4K HDR processor X1™. Images filmed in 2K and even Full HD is upscaled close to 4K resolution by 4K X-Reality™ PRO using a unique 4K database.
