77-Inch OLED Smart TV with Surge Protection

The Samsung S90FA series delivers a 77-inch OLED panel at 4K resolution with a 120Hz native refresh rate. It is built for viewers who want self-emissive contrast and AI-enhanced upscaling in a large-screen format. The bundle includes an Austere 5S-PS4-US1 surge protector with PureFiltration technology.

4K Resolution and 144Hz Motion Headroom

The 3840 x 2160 panel handles native 4K content and upscales lower-resolution sources through the NQ4 AI Gen3 Processor with 128 neural networks. Motion Xcelerator supports up to 144Hz for compatible gaming signals, while the 2.1 speaker configuration with Dolby Atmos and OTS Lite covers everyday audio without external speakers.

Thermals Noise and Power Protection

OLED pixels emit their own light, eliminating backlight bleed and reducing panel heat compared to traditional LED designs. The included Austere unit provides 3000J surge protection, flameless MOV safeguards and overcurrent protection across four outlets plus a 20W USB-C Power Delivery port and Omniport USB charging.

Wireless Connectivity and Smart Platform

Wi-Fi 5 and Bluetooth connect the TV to networks and peripherals while the Tizen OS streams apps and supports Samsung Health. Four HDMI inputs and two USB-A ports accommodate consoles, media players and storage. The Eco Sensor and Auto Power Saving modes reduce electricity draw during idle periods.
