The Samsung QN90F is a 4K mini-LED TV with a 120Hz native refresh rate. It can display high dynamic range ( HDR) content in HDR10, HDR10+, and hybrid log gamma (HLG), though Samsung continues to eschew Dolby Vision support. It has an ATSC 1.0 tuner for over-the-air broadcasts, but no ATSC 3.0 tuner for 1080p and 4K OTA broadcasts.

Like the QN900D, the new-and-improved QN990F 8K Neo QLED leverages Samsung's NQ8 Gen3 processor for all things picture performance, upscaling, and the like. The QN990F will also share in its predecessor's matte-finish anti-glare coating, which works well in toning down glare if you watch TV in a more ambient-lit environment.

For gamers and sports lovers, the QN990F feature Samsung’s Motion Xcelerator 240Hz and AI Motion Enhancer Pro for enhanced motion clarity. Dedicated upward-firing speakers power Dolby Atmos immersive sound, while Object Tracking Sound Pro provides audio that follows the on-screen action for enhanced audio realism.
