A:Answer Hi Chase! The QN800A & QN900A both include features such as: Neo Quantum Processor 8K with 8K AI Upscaling, Quantum Matrix Technology Pro with Mini LED Backlighting, Motion Xcelerator Turbo+, Freesync Premium Pro, Ultra Viewing Angle, Expert Calibration, Active Voice Amplifier, Q-Symphony (when paired with a compatible Q-Series Soundbar), and many more.
The QN800A features Quantum HDR 32X, 70 Watt 4.2.2 Channel sound, and the Infinity One Design – a thin display at just 15mm and a boundless screen design enhancement that minimizes the bezel of the TV. When stepping up to the QN900A, you will gain Quantum HDR 48X (Quantum HDR 64X on 75” & 85”), 80 Watt 6.2.2 Channel sound, as well as a more immersive viewing experience with the Infinity Screen – a 99% screen to body ratio, leaving virtually no bezel on the TV, resulting in a truly immersive 8K experience. ^Gina
