Excellent picture

The flagship Samsung S9 comes as a 77-inch OLED TV with a slim body just 4.5 cm thick (without the stand). The self-emissive organic LED screen delivers reference-level contrast, a wide color gamut, and great visibility from any angle, making it an excellent choice for movies and sports, including when friends are over. Even out of the box, the TV offers accurate color reproduction, confirmed by Pantone certification.

Image processing is handled by the NQ4 AI Gen2 processor: it sharpens lower-resolution content, applies AI algorithms, and enables Samsung’s signature technologies—Real Depth Enhancer and Dynamic Black EQ.

For gamers and sound lovers

The Samsung QE-77S90D is great for gaming: the refresh rate ranges from 100 Hz (by default) up to 144 Hz (with Motion Xcelerator). There’s HDMI 2.1, support for AMD FreeSync Premium, and a Game Bar with advanced settings, including a 21:9 or 32:9 screen format.

Sound comes from a 40 W speaker system with a subwoofer and Dolby Atmos support. Q-Symphony lets you easily sync the TV with a Samsung soundbar for even more immersive audio.

A multimedia hub and smart home center

The TV runs on Tizen—a fast, convenient platform with a wide selection of apps. The remote with a microphone supports voice control, and its built-in battery can charge from a solar panel. The model integrates not only with the Samsung SmartThings ecosystem, but also with other smart homes thanks to the Matter standard and a built-in Zigbee / Thread module. You can connect via Wi‑Fi as well as specialized protocols.

The Samsung QE-77S90D is a cutting-edge OLED TV with a big screen that’s equally great for movies, gaming, and multimedia.
