SAMSUNG QN48S90F 48 inch OLED 4K Smart TV (2025)

48 inch OLED Smart TV

The Samsung QN48S90F is a 48 inch 4K OLED television built for viewers who want deep contrast and AI-enhanced picture quality in a living-room or bedroom setup. It runs the 2025 S90F platform with the NQ4 AI Gen3 processor and Vision AI features for streaming, gaming and live sports. Buyers who need a larger screen diagonal or a higher peak-brightness panel for bright-room HDR will not find those capabilities here.

128 neural network upscaling and 144Hz motion

The NQ4 AI Gen3 processor uses 128 neural networks to upscale all sources to 4K resolution through 4K AI Upscaling Pro. OLED HDR+ and Auto HDR Remastering expand contrast and colour, validated by Pantone. Motion Xcelerator 144Hz supports variable refresh rate gaming at 4K 144Hz, while AI Motion Enhancer Pro reduces blur on fast-moving objects. Content mastered above 4K or at refresh rates beyond 144Hz cannot be displayed natively.

Object Tracking Sound Lite with Dolby Atmos

Object Tracking Sound Lite and Dolby Atmos create a virtual surround stage that follows on-screen action without external speakers. The AI processor optimises audio in real time for dialogue clarity and spatial effects. Users who require discrete multi-channel output or high-wattage built-in amplification for large rooms will need a separate sound system.
