What is Dolby Vision and do I need it?

Dolby Vision has the potential to improve consumers' viewing experience by constantly optimising the way their TVs deliver HDR pictures – just as the rival HDR10+ format does. It also gives content producers more control over how their HDR programming appears on TVs.

4K (Ultra HD) is a high-density pixel resolution that provides greater detail in video images. HDR10 and Dolby Vision are color and dynamic range enhancements that provide a more realistic representation of content. Many devices that support HDR10 or Dolby Vision also support 4K.

And while Dolby Vision is currently capable of producing a better image quality, there are no TVs that could take full advantage of what it provides as opposed to HDR10. However, Dolby Vision does offer a better picture quality, mainly due to its dynamic metadata.

The key with Dolby Vision is that it requires specific equipment and training in order to master the content. This further ensures that the content was mastered correctly. This gives Dolby Vision a leg up on the competition and makes it worth the extra cost.

What to do it the HDMI connection only supports 1080p Dolby Vision. If your TV supports Dolby Vision but not at 4K resolution, you will see the following message. In this case, your TV is only capable of displaying 4K Dolby Vision at 30fps which is not supported by Netflix and other streaming channels.

The main difference between Dolby Vision and HDR10 is the colour depth and brightness the content and equipment is capable of achieving. Dolby Vision content is mastered up to 12-bit colour depth, compared to HDR10's 10-bit (which is where HDR10 gets its name from).

HDR10 is a compalient format and HDR400 only means the lowest requirement for HDR format illumiation. They are not comparable.

Dolby Vision is a set of technologies developed by Dolby Laboratories for high dynamic range (HDR) video.

To find 4K HDR content on Netflix, you need a 4K TV and/or a 4K HDR capable device that supports Netflix. For the best picture quality, devices need to be compatible with HDR10 or Dolby Vision HDR, especially the latter as Netflix produces a fair chunk of its original programming in 4K Dolby Vision HDR.

HDR10+ works differently than HDR10. It sends dynamic metadata, which allow TVs to set up colour and brightness levels frame-by-frame. This makes the picture look realistic. HDR10 aims to produce 1000 nits of peak brightness, whereas HDR 10+ supports up to 4000 nits.

Dolby Vision IQ, announced in 2020, is an upgrade that works with specific hardware. It requires built-in sensors to read how much ambient light is present, adjusting the video you're watching accordingly.

High Dynamic Range (HDR) is very awesome, that much isn't in doubt. But it's also still very much in the early stages when it comes to content, and importantly, the devices that support it. There are a number of TVs that support HDR, but you're unlikely to be using one as a PC monitor.

Samsung TVs do not support Dolby Vision, due to additional manufacturing costs and additional license fees. However, depending on the Samsung TV model it may support its own processing system and hardware HDR10+, without the need for Dolby Vision.

As a general rule, all 4K TVs currently on the market and going forward should support HDR10. This means your TV will be compatible with the most widely available 4K Blu-ray discs, 4K players and 4K streaming content – and it should offer a far better picture than a 4K TV without any HDR.

Samsung has shown no sign of relenting in 2022 and including Dolby Vision support in its TVs.

You don't get a movie in Dolby Vision, but if your television has HDR10 you get the movie in basic High Dynamic Range — if it's got neither, then you get it with a standard dynamic range.

Yes, Dolby Vision encoded content will display HDR on a TV with HDR10. Of course, you would need a TV that supports DV to see the improved picture quality DV provides.
