What is UHD Dimming in Samsung H Series TV?
The term "Dimming" gets used frequently in LED LCD marketing. It's one of the few such terms that can actually denote improved picture quality.
UHD Dimming precisely scans an incredible amount of zones across the entire image and adjusts brightness to deliver deeper darks and brighter whites. It virtually eliminates the "halo" effect and image distortion, so you’ll enjoy a crystal clear picture.
