The Samsung OLED 4K S90F Smart TV is an OLED TV model from Samsung's 2025 product line, aimed at users who want to upgrade their home entertainment, sports, gaming, and viewing experience. The S90F series is positioned by Samsung with a 4K OLED screen, Samsung Vision AI platform, NQ4 AI Gen3 Processor , 4K AI Upscaling Pro technology , OLED HDR+ , and a refresh rate of up to 144Hz .

Modern, slim design, suitable for high-end living spaces.

The Samsung S90F impresses with its minimalist design, thin bezels, and sleek center stand. This style allows the TV to easily blend into various spaces such as living rooms, bedrooms, home entertainment rooms, or modern apartments.

The strength of the Samsung OLED 4K S90F Smart TV's design lies in the feeling of a 'screen that stands out from the bezel'. When watching movies or playing games, users can focus on the content instead of being distracted by the TV bezel.

The 4K OLED display delivers deep blacks and impressive contrast.

One of the reasons the Samsung OLED 4K S90F Smart TV is attracting attention is its OLED screen technology. With self-illuminating pixels, the TV is capable of reproducing deep blacks, high contrast, and images with greater depth than many conventional LED TVs.

Samsung states that the S90F uses OLED HDR+ technology , in which the processor analyzes each frame to optimize brightness and contrast, resulting in clearer detail in both bright and dark areas.

NQ4 Gen3 AI Processor: Smarter Image Enhancement

The Samsung OLED 4K S90F Smart TV is equipped with the NQ4 3.0 AI processor with 128 intelligent networks . According to Samsung Vietnam, this processor supports image and sound enhancement, and helps content from OTT platforms, live sports, or games achieve better display quality on the 4K screen.

4K AI Upscaling Pro technology helps recognize content and upscale its resolution to near 4K, which is especially useful when users watch online videos, older movies, or content with quality lower than 4K.

Refresh rate up to 144Hz: a major advantage for gamers.

For gamers, the Samsung S90F is a very worthwhile option. The TV supports Motion Xcelerator 144Hz , delivering smoother motion when playing fast-paced games. Samsung notes that 4K 144Hz quality is only available with PC games that support this specification and require a compatible graphics card.

A high refresh rate helps reduce motion blur, screen tearing, and lag during fast-paced action. This is a big plus for those who frequently play racing, shooting, sports, or open-world games.

Immersive Dolby Atmos sound

Beyond just focusing on image quality, the Samsung OLED 4K S90F Smart TV also supports Dolby Atmos . According to Samsung, the speaker system combined with Dolby Atmos creates a multi-dimensional surround sound experience, providing a more immersive feeling when watching action movies, sports, or entertainment programs.

For a better experience, users can combine the TV with a Samsung soundbar that supports Dolby Atmos, especially in a large living room or dedicated entertainment space.

Smart TV platform, easy to use.
