77" OLED Smart TV for Home Cinema

The Samsung S85FA series delivers a 77-inch OLED panel with 4K resolution and a 120Hz refresh rate. Its self-lit pixels produce deep contrast and vibrant colour without a backlight. The NQ4 AI Gen2 processor uses 20 neural networks to upscale content to 4K and optimise sound. This 2025 model runs the Tizen smart platform with multiple voice assistants built in.

Connectivity and Placement in a Living Room

Four HDMI inputs and two USB-A ports accommodate consoles, streamers and external drives. Wi-Fi 5 and Ethernet give flexible network options, while Bluetooth pairs headphones or speakers. The Graphite Black contour design suits wall mounting via VESA or a tabletop stand. Q-Symphony Pro synchronises the TV speakers with a compatible Samsung soundbar for a wider front stage.

Thermals, Noise and Power in Daily Use

OLED technology emits light per pixel, so no backlight cooling fan is required and the panel runs silently. The Eco Sensor adjusts brightness to ambient light, reducing power draw during darker scenes. Auto Power Saving and Auto Power Off further limit consumption when the TV is idle. The included SolarCell remote recharges from indoor light, eliminating disposable batteries.

Questions about this item

What is the 120 Hz refresh-rate limit during extended gaming sessions?

Motion Xcelerator 120Hz keeps motion smooth at the full 120 Hz refresh rate for fast-paced content.

How much heat and fan noise does the 77" OLED panel produce after hours of use?

OLED pixels emit their own light without a backlight, so the panel runs cooler and silently compared with traditional LED designs.

Which devices or cables must I already own to use the four HDMI inputs?

Any 4K source with an HDMI cable — game console, streaming box, or Blu-ray player — will connect directly to the four HDMI ports.
