Uncover the detail with 4K HDR

A High Dynamic Range (HDR)-compatible TV will change the way you look at TV. Combined with 4K Ultra HD resolution, HDR video content delivers exceptional detail, color and contrast, with a far wider range of brightness than other video formats. The result is the most lifelike picture TVs have ever been able to create, with brilliant highlights and fine detail.

Rediscover every detail with 4K X-Reality™ PRO

Discover a thrilling world of extraordinary clarity. Every single pixel is enhanced beautifully by our most powerful 4K picture processing technology ever. Individual parts of each scene are analyzed and matched with a special image database that independently addresses texture, contrast, color, and edges. The difference is clear with supremely lifelike detail, whatever you're watching.

Made to listen: ClearAudio+

Make your listening as lifelike as your viewing. ClearAudio+ fine-tunes TV sound for an immersive experience that seems to surround you. Hear music, dialog, and surround effects with greater clarity and separation, whatever you're watching.

DSEE restores detail to your digital music

Low-resolution Internet video, catch-up TV and other heavily compressed audio files don’t always sound so great. A large amount of information gets thrown away when digital audio is compressed. With Digital Sound Enhancement Engine (DSEE) technology, lost frequency components (especially high frequencies) are restored for natural sound with a more spacious feel.

Motionflow™ XR keeps the action smooth

Enjoy smooth and sharp details even in fast-moving sequences with Motionflow™ XR. This innovative technology creates and inserts extra frames between the original ones. It compares key visual factors on successive frames, then calculates the split second of missing action in the sequences. Some models also include black-frame insertion for a blur-free and truly cinematic look.

Clear Phase for smooth, balanced frequencies

BRAVIA® uses a powerful computer model to analyze and compensate for inaccuracies in speaker response. It does this by "sampling" the speaker frequency with higher precision. This information is fed back to cancel out any peaks or dips in the speaker’s natural response — resulting in pure, natural audio with smooth, even reproduction of all frequencies.

Great entertainment wirelessly with built-in Wi-Fi

Link up easily to your home network. With built-in Wi-Fi, you’re free to go online and browse movies, enjoy video channels like YouTube™ and access services such as on-demand TV. Best of all, you can stream entertainment from your wireless home network and the Internet without the clutter of cables.

Cinematic S-Force Front Surround

Enjoy an immersive soundstage that pulls you into the heart of the action. S-Force Front Surround mimics the way the brain correlates sound sources to create proper volume, time lag, and sound wave spectrum — using only left and right speaker channels. By naturally emulating three-dimensional sound fields, you’ll enjoy rich, high-fidelity audio across a wider listening area.
