Hi Nick,
The QN70H comes with a power cable. If you plan to connect external devices such as a soundbar, game console, or cable box, you'll need an HDMI cable for those connections.
Processing & Picture: Both use Quantum Mini LED technology with Samsung Vision AI and 4K AI upscaling, but the QN90F steps up to the NQ4 AI Gen3 Processor with 4K AI Upscaling Pro, adds Glare Free, Auto HDR Remastering Pro, and enhanced HDR for brighter, more refined picture quality. Motion: The QN70H supports Motion Xcelerator with DLG 120Hz (55" and larger), while the QN90F increases to Motion Xcelerator 165Hz with AI Motion Enhancer Pro. Audio: The QN70H features Object Tracking Sound Lite (2CH / 20W), while the QN90F upgrades to Object Tracking Sound+ with Dolby Atmos, higher output, and more immersive audio. Design: The QN70H features an AirSlim design with an adjustable stand, while the QN90F steps up to a NeoSlim design with a Glare Free display. Smart: Both include Samsung Vision AI features with similar functionality, while the QN90F adds a few extra AI conveniences such as Click to Search, Universal Gestures/Quick Control, ConnecTime, and Screen Vitals.
