NOW has launched a long-awaited new add-on that unlocks 4K Ultra HD resolution with HDR and Dolby Atmos. Dubbed Ultra Boost, this optional extra costs £9 per month — or an extra £108 over the course of a year. It builds on the Boost add-on, launched over a decade ago, that improves picture quality up to 1080p HD and adds support for Dolby Digital 5.1 surround sound. Subscribing to Boost allows two people to watch using the same login, while Ultra Boost increases that to three people.
