77-inch OLED Smart TV for home entertainment

The Samsung S90FA series delivers a 77-inch OLED panel with 4K resolution and a 120 Hz native refresh rate. AI-driven upscaling uses 128 neural networks to sharpen lower-resolution sources. Dolby Atmos and a 2.1 speaker configuration provide immersive sound for films, sports and streaming.

Screen cleaner and extended coverage included

A 6.8 oz 200 ml spray cleaner is bundled for safe maintenance of the OLED surface. An Amber protection plan adds one year to the standard manufacturer warranty, covering the set for residential use only. Both accessories arrive in the same carton as the television.

Graphite Black chassis

The graphite black cabinet houses four HDMI inputs, Ethernet, Wi-Fi 5 and Bluetooth for flexible connectivity. VESA mounting points allow wall installation, while the included SolarCell remote charges via indoor light. The 120 Hz panel supports motion-enhanced gaming up to 144 Hz through compatible sources.

Questions about this item

Will the 2.1 speaker setup or the 6.8oz screen cleaner need periodic replacement?

The 2.1 speakers are built into the panel and do not require scheduled replacement; the 6.8oz cleaner is a one-time supply you replenish only when empty.

What limit appears first during extended 120Hz or 144Hz gaming sessions?

The panel runs at a fixed 120Hz native refresh rate with Motion Xcelerator support up to 144Hz, so the hard ceiling is the 120Hz hardware limit.

How much heat or fan noise does the 128-network NQ4 AI Gen3 Processor generate after hours of use?

The TV uses passive cooling with no internal fan, so operation stays silent; warmth stays within normal OLED panel levels during all-day viewing.
