Samsung S90F 55" 16:9 120Hz 4K HDR OLED Smart TV

The Samsung QN55S90FAFXZA is a 55 inch smart TV that uses an OLED panel and delivers native 4K resolution. Each pixel produces its own light, so black levels stay true and contrast remains high, while color accuracy meets the Pantone standard.

Inside, the NQ4 AI Gen3 processor examines every frame in real time, upscales lower resolution sources to near 4K clarity, and fine tunes both picture and audio according to what is on screen. Whether you stream a classic film, tune in to live sports, or watch user generated content, the processor presents a sharp, balanced image.

For gamers, the native 120 hertz panel supports variable refresh rates up to 144 hertz through FreeSync Premium Pro. Fast on-screen action stays clear and input lag remains low. Auto Low Latency Mode engages as soon as a console or PC connects, and the four HDMI ports provide bandwidth for high frame rate play, eARC for a soundbar, and simple cable management.

Sound comes from a built in 40 watt system arranged in a 2.1 channel layout. Dolby Atmos processing and Object Tracking Sound Lite create a wide, directional audio field, so a plane flying overhead on screen seems to move above you in the room. If you prefer an external speaker setup, eARC sends uncompressed audio to your receiver with a single cable.

The TV runs on the Tizen operating system. A quick, tile based interface brings together major streaming services, Samsung TV Plus with more than 2,700 free channels, and a dashboard for connected devices. Built in Alexa, Bixby, and Google Assistant support let you search for content or adjust settings with voice commands. Because the set includes a SmartThings hub, it can also act as the center of a smart home, so you can dim compatible lights, check the thermostat, or view a doorbell camera directly on the screen.

Wi Fi 5 and Bluetooth 5.3 handle wireless connectivity, making it easy to pair headphones for late night viewing or to mirror a phone without cords. A simple stand fits most media furniture, yet the slim chassis also mounts flush to the wall with a VESA bracket.

From a city apartment living room to a dedicated gaming den, the Samsung QN55S90FAFXZA offers picture accuracy, responsive performance, and smart features that adapt to many entertainment setups without complicated calibration.
