"The dramatic improvement of screens in battery operated devices, coupled with the emergence of 4K and 4K with HDR streaming offerings through services such as Amazon, Netflix and others, makes it possible for consumers to get a much richer and more immersive experience on their computers, tablets and smartphones," said UHDA President, Hanno Basse.
