The Sony BRAVIA 8 is a 77-inch 4K OLED TV built around over 8 million self-lit pixels, with Sony's XR Contrast Booster and XR Triluminos Pro processing for deep blacks and rich color. Its standout trick is the screen-as-speaker design, which produces sound that seems to come from the picture itself. It supports Dolby Vision, Dolby Atmos, IMAX Enhanced and HDMI 2.1 with 4K/120 for consoles. It suits movie lovers and PS5 or Xbox owners who want cinematic picture and immersive sound in one set, and it competes with other premium OLEDs on processing and built-in audio rather than on brightness alone.

Owners of Sony's OLED sets generally praise the deep blacks, accurate color and the screen-speaker audio, and console players value the 4K/120 support. Common complaints center on brightness in sunlit rooms and the size and weight of the largest panels.
The Sony BRAVIA 8 is a 77-inch 4K OLED smart TV with a slim design. Its over 8 million self-lit pixels are enhanced by XR Contrast Booster 15 for deep blacks and bright highlights. XR Triluminos Pro widens the range of colors, and the XR Processor adjusts color, contrast and clarity in real time.
The screen works as the speaker. Acoustic Surface Audio+ uses actuators behind the panel to turn the whole screen into a speaker, so sound follows the action on screen. Voice Zoom 3 keeps dialog clear. The TV supports Dolby Atmos, DTS:X and 3D Surround Upscaling.
It runs Google TV, which brings streaming apps together in one interface, and includes Google Assistant. Netflix, Prime Video, Disney+, YouTube, the Apple TV app and Crunchyroll are among the supported apps. You can stream from Apple devices with AirPlay 2 and from Android devices with Chromecast built-in. Kids Profiles let parents restrict streaming services, limit watching time and set a bedtime.
