This bundle pairs a 77-inch OLED 4K Smart TV with a 3.1-channel soundbar and subwoofer. The TV uses an NQ4 AI Gen2 Processor with 20 neural networks to upscale content to 4K. It runs the Tizen smart platform with multiple voice assistants. The soundbar adds Dolby Audio and a dedicated centre channel for clearer dialogue.

The 120Hz panel with Motion Xcelerator 120Hz keeps fast motion smooth during sport and gaming. OLED HDR delivers per-pixel contrast without a backlight. Anti-reflection coating and Ultra Viewing Angle preserve colour and brightness when viewed off-centre. Active Voice Amplifier Pro and Adaptive Sound Pro adjust audio in real time to room noise.

HDMI eARC and wireless setup

Four HDMI inputs support eARC for lossless audio passthrough to the soundbar. The soundbar connects wirelessly to the TV via Q-Symphony Pro for synchronised output. Bluetooth and Wi-Fi 5 handle streaming and 360 Audio from mobile devices. The included SolarCell remote charges from light to reduce battery changes.

Questions about this item

How much heat does the 77" OLED panel generate when running at 120Hz for extended periods?

The S85F OLED panel is designed for continuous 120Hz operation; its graphite-black chassis and contour design dissipate heat passively without an internal fan, so surface temperatures stay low during all-day viewing.

Which existing audio connections must I already have to use the 3.1ch soundbar with this TV?

Connect the HW-B630F via the TV's HDMI eARC port (one of the four HDMI inputs) or use the optical audio output; the soundbar also pairs wirelessly over Bluetooth if you prefer a cable-free link.

Will the TV's Tizen smart platform and HDMI 2.1 ports work with my older 1080p Blu-ray player and game console?

Yes — the four HDMI inputs accept legacy 1080p sources, the NQ4 AI Gen2 processor upscales them to 4K using 20 neural networks, and Tizen recognises older HDMI-CEC devices for unified remote control.
