What is Dolby Vision?

By Mike Atherton 08 Mar 2018

Most of us know Dolby for great sound, rather than vision. They’ve been at the forefront of audio technology for the last 50 years and they’re now bringing all that experience into the video arena.

Dolby has taken everything they know about creating the perfect cinema experience and come up with Dolby Vision, which actually builds on existing HDR technology. HDR stands for High Dynamic Range and gives you a much wider range of colours, with a higher contrast ratio. This means you’ll get a picture that’s much closer to real life - take a look at our ‘What is HDR?’ article to find out more.

The thing to bear in mind is that content needs to be made using HDR to be able to watch it on a TV that comes with HDR included, and the amount of available HDR content is growing fast.

How does Dolby Vision work?


HDR sends data to your TV telling it how to display the movie, or programme you’re watching, so you see it exactly as the director intended. What Dolby Vision does is add an extra layer to the HDR data that’s sent to your TV which means your TV can now be told how to display each individual scene. This is great for content creators because it gives them much more control over how their movies are displayed, and it’s great for the rest of us because we get to watch our favourite TV shows and movies in more detail than ever.

You don’t need to spend a fortune to get a Dolby Vision HDR TV either, with TVs like this 43” LG Ultra HD TV coming in at just £359.

Take a look at our full range of TVs with Dolby Vision here.

Hopefully, that’s everything you need to know about Dolby Vision. If you need help with anything else, you can contact one of our Team Knowhow experts here.
