Wonder why you can only get Dolby Vision's high dynamic range video on a limited number of devices? It's because you've needed specialized hardware -- if a device wasn't designed with Vision in mind, you're out of luck. Expect to see it in many more places before long, though. Dolby tells Forbes that Vision is now available in pure software form, enabling its take on HDR for any reasonably capable device. In theory, your console, media hub or TV can get Vision support through an update. It could also lower the cost of including Vision by avoiding the cost of dedicated components.
