Ultra Clear Panel

  • The Samsung Ultra Clear Panel absorbs ambient light, reduces reflections and lets the picture come to life. It displays deeper blacks and enhanced contrast for crystal clarity, without glare, so you can see clearly and enjoy more detail.

UHD Upscaling

  • UHD Upscaling delivers the complete UHD picture experience with a proprietary process including signal analysis, noise reduction, UHD upscaling and detail enhancement to seamlessly upconvert SD, HD or full HD content to near UHD-level picture quality.

UHD Dimming

  • UHD Dimming precisely scans an incredible amount of zones across the entire image and adjusts brightness to deliver deeper darks and brighter whites. It virtually eliminates the "halo" effect and image distortion, so you’ll enjoy a crystal clear picture.

Quad Core

  • This powerful processor speeds up your Smart Hub experience. It gives you a faster browsing experience and enables you to switch between apps, stream content and multi-task faster. Plus, your TV will turn on 4x faster with Instant On.
