Samsung S90D 77" 16:9 144Hz 4K HDR OLED Smart TV

The Samsung QN77S90DAFXZA is a 77 inch OLED Smart TV that brings native 4K UHD resolution, lifelike HDR10 Plus highlights, and a smooth 144 Hz refresh rate into your living room. It is a clear match for film lovers who want rich contrast, gamers who need rapid response, and anyone who streams shows or sports and expects every detail to stay sharp.

At the heart of the set, the NQ4 AI Gen2 processor analyzes incoming video, upscales lower resolutions to 4K, and tunes brightness and color in real time based on both the scene and the lighting in your room. Because the panel is PANTONE validated, colors remain faithful to creative intent, whether you are watching a new release or revisiting a classic.

Sound is handled by a built-in 2.1 channel system that delivers 40 watts of power. Dolby Atmos support and Object Tracking Sound Lite create a sense of dimensional audio, letting dialogue and effects feel anchored to the action on screen. Most viewers will find this setup satisfying on its own, and those who want more can connect a soundbar through HDMI eARC without fuss.

Four HDMI 2.1 ports allow consoles and media players to run at up to 144 Hz while keeping features such as variable refresh rate and automatic low-latency mode active. Wi-Fi 6E and Bluetooth 5.2 bring fast wireless connectivity for streaming, pairing headphones, or adding a wireless rear speaker kit.

The TV runs on Samsung Tizen OS, which places popular apps, Samsung TV Plus live channels, and the Gaming Hub on a single home screen. Alexa is built in for voice searches, hands-free control, and smart-home commands, so you can dim the lights or check the weather without reaching for another device.
