The reason consumer TV manufacturers are promoting HDR/4K when very little content exists is the same reason they’ve been selling 4K sets and 3DTVs before that: they need to make money. “We want to speed up the TV replacement cycle, especially with the addition of HDR,” said Peter Fannon, vice president of corporate and governmental affairs for Panasonic.
