Specifications
NQ4 AI Gen2 Processor
Powered by 20 neural networks, the NQ4 AI Gen2 Processor makes the movies, shows, games and sports you love look even better — upscaling lower-resolution sources toward beautiful 4K and optimizing the sound to match, so every kind of content gets a lift the moment it hits the screen.
Quantum Matrix Technology Slim
This innovative lighting technology precisely controls a dense field of proprietary Quantum Mini LEDs to unlock detail across the picture. Every scene arrives with sharp, accurate contrast — whether the moment is hidden in deep shadow or lit by bold, bright highlights.
4K AI Upscaling
Watch shows, movies and games in captivating 4K. The advanced AI processor upscales your content using 20 AI neural networks, delivering sharp, smooth picture quality no matter what you're watching or where it came from.
Neo Quantum HDR
See every moment come to life with more clarity, bolder brights and inky blacks. The NQ4 AI Gen2 processor analyzes each scene and dynamically enhances brightness for deeper contrast, and with HDR10+ each scene is tone-mapped for optimal contrast and richer detail.
Motion Xcelerator 144Hz
Play games and watch sports with exceptional motion clarity and minimal lag or blur. Dynamic refresh technology supports VRR gaming up to 4K 144Hz, so visuals stay crisp and ultra-smooth through all the non-stop action.
FreeSync Premium Pro
Built on AMD FreeSync core technology to cut stutter and screen tearing, FreeSync Premium Pro delivers a true HDR gaming experience while keeping latency low for effortlessly smooth, responsive gameplay.
Object Tracking Sound Lite & Q-Symphony
A virtual top channel places sound in space and moves it with the action on screen, pulling you into the middle of every scene. Pair a Samsung soundbar and Q-Symphony plays the TV and soundbar speakers together for a fuller, more enveloping soundstage. Soundbar sold separately.
Endless Free Content with One UI Tizen
