Key Features of the Samsung 77 Inch S90F
OLED Picture Quality with Self-Illuminating Pixels
The Samsung S90F features OLED display technology with over 8 million self-illuminating pixels. Each pixel emits its own light, allowing the TV to achieve true black levels, vibrant colors, and precise brightness control without traditional backlighting.
This results in superior contrast, deeper shadows, and vivid detail that enhances everything from cinematic films to live sports broadcasts.
OLED HDR for Dynamic Brightness and Color
The S90F supports OLED HDR and HDR10+, improving brightness, contrast, and color depth scene by scene. This ensures that bright highlights appear more realistic while darker scenes retain clear shadow detail.
The improved dynamic range makes the TV ideal for watching HDR movies, nature documentaries, and premium streaming content.
NQ4 AI Gen2 Processor with Intelligent 4K Upscaling
At the core of the Samsung S90F is the NQ4 AI Gen2 Processor, which uses multiple neural networks to analyze images and optimize picture quality in real time.
Samsung’s AI 4K Upscaling improves lower-resolution content by enhancing detail, reducing noise, and sharpening textures so that HD and Full HD content appears closer to native 4K resolution.
Immersive Audio Experience
The Samsung S90F supports Dolby Atmos and features a powerful 2.1 channel 40W audio system designed to deliver rich, room-filling sound.
Samsung’s Q-Symphony technology allows compatible Samsung soundbars to work together with the TV speakers rather than replacing them, creating a wider and more immersive soundstage.
This combination provides clear dialogue, enhanced effects, and balanced sound performance for movies, sports, and gaming.
