Netflix has launched support for high dynamic range streaming content, starting with the first season of “Marco Polo.” Fans of the original series who have HDR-supported TVs will be treated to vibrant visuals, including “much higher brightness levels and a greater range between dark and light,” explains PCWorld. “Subscribers will need Netflix’s 4K Ultra HD plan,” and the company “recommends Internet speeds of at least 25 Mbps per second.” While “Daredevil” will also get HDR in the future, Netflix has yet to announce additional series to do the same. LG, Samsung, Sharp, Sony and Vizio are among the TV manufacturers shipping HDR-supported sets.
