Bundle contents

This package pairs a 77-inch 4K OLED Smart TV with a 3.1-channel soundbar and subwoofer. The television delivers self-emissive pixels for deep contrast and runs on the NQ4 AI Gen3 Processor with 128 neural networks. The included audio system adds Dolby Audio support and a dedicated subwoofer for low-frequency impact. Together they form a single-box home-cinema upgrade.

Who this suits and who it does not

The set fits buyers who want a large OLED screen and an integrated soundbar without separate component research. It serves streaming, gaming at 120 Hz, and live sports with AI upscaling and Motion Xcelerator 144 Hz support. Households needing more than four HDMI inputs or a higher-channel surround system should look at alternative configurations. The TV’s 2.1 built-in speakers are supplemented but not replaced by the bar.

Capacity and headroom

The 3840 x 2160 panel at 120 Hz (up to 144 Hz) handles 4K HDR content and fast-motion gaming with headroom for variable refresh rates. OLED HDR+ and Auto HDR Remastering expand dynamic range within the panel’s peak brightness limits. The 3.1-channel bar covers front, centre and bass duties; rooms requiring rear-channel immersion or object-based height audio will exceed its native capability.

Questions about this item

Does the TV need an external aerial or satellite box to show Freeview channels?

The S90FA has a built-in V-Chip tuner for over-the-air broadcasts, so an aerial cable is sufficient; no separate set-top box is required.

Will the HW-B630F 3.1ch soundbar work with the TV's eARC port for Dolby Atmos pass-through?

The bundle includes the HW-B550F 2.1ch soundbar with Dolby Audio, not the 3.1ch model, and connects via HDMI eARC for simplified audio return.

How can I confirm the panel is running at 120 Hz after connecting a games console?

Open the TV's Game Bar overlay or Motion Xcelerator settings; both report the active refresh rate, which should read 120 Hz for compatible sources.
