UHD Alliance Bows ‘Mobile HDR Premium’ Logo for Smartphones, Tablets, Laptops

Smartphones, tablets and laptops with 10-bit depths that can reproduce 90 percent of digital cinema’s P3 color space and have peak luminance of 540 nits can qualify for the UHD Alliance’s new “Mobile HDR Premium” certification logo, the group said Tuesday at the Mobile World Congress in Barcelona. Qualified mobile devices also must have resolutions of 60 pixels per degree to earn the logo, the alliance said. A Samsung Galaxy S7 smartphone with a 5.7-inch screen and 2560×1440 resolution qualifies when viewed from a distance of seven inches, according to an online Nvidia screen density calculator. An iPad Pro with a 10-inch screen and 2048×1536 when viewed from 13 inches also would qualify, as would a 1080p Lenovo Flex 4 laptop with a 14-inch screen viewed from 21 inches. Licensing of the Mobile HDR Premium logo will start April 1, the alliance said. “Portable devices are a primary mode of video consumption and the category itself is a key component of the rapidly expanding Ultra HD ecosystem,” said President Hanno Basse in a statement.
