What Common Both Can Do?

  • Display Technology: Both televisions use OLED display technology, which allows each pixel to emit its own light independently. This results in exceptional contrast control and eliminates the need for a traditional backlight.
  • Resolution: Each model features a native 4K resolution, delivering sharp detail and clarity across movies, TV shows, and streaming content. This resolution ensures compatibility with modern content standards.
  • Self-Emissive Pixels: Both TVs rely on self-emissive pixels that can turn on and off individually. This enables precise light control and prevents light bleed across dark scenes.
  • Perfect Black Levels: Each model can produce true black by completely shutting off individual pixels. This enhances depth and realism, especially in dark scenes.
  • Infinite Contrast Ratio: Both displays achieve an effectively infinite contrast ratio due to OLED pixel control. This improves visual separation between bright highlights and deep shadows.
  • HDR Support: Both TVs support high dynamic range content, allowing for improved brightness range and color depth compared to standard dynamic range video.
  • HDR Formats: HDR10 and HLG are supported on both models, ensuring compatibility with broadcast HDR content and most streaming platforms.
