Richer, more natural pictures – with Dolby Vision and HDR10+

Dolby Vision and HDR10+ supply frame-by-frame metadata to dynamically adjust brightness and contrast, expanding the range of visible detail. Dolby Atmos handles object-based audio, placing sound elements around the room for a more immersive soundtrack.

More lifelike highlights and deeper shadow detail improve film and series viewing. Atmos creates a cinema-like soundstage when paired with compatible sound systems.

Smoother 4K playback in crowded homes – thanks to Wi‑Fi 6 support

Wi‑Fi 6 reduces wireless congestion on networks with many connected devices, handling simultaneous streams more efficiently. Improved airtime management and lower latency help prevent buffering during high-demand periods.

Stable 4K streams are more likely even when smartphones and laptops are active. Fewer interruptions keep family viewing sessions uninterrupted.

Convenient hands-free control – with Alexa Voice Remote

Voice commands allow content search, playback control and smart home actions using Alexa. The remote also includes preset app buttons and direct TV power and volume control.

Finding shows and adjusting playback works without navigating menus manually. Smart home tasks like dimming compatible lights become part of the viewing routine.
