Dolby vision not working

Hi there Srivyshnav,

If Dolby Vision is not working as expected, first ensure all the requirements are met here:

Here's what you need to watch the highest-quality video available

• Video content with a high-quality version that you purchased or rented.

• A device capable of playing high-quality video content:

• See Mac models that support HDR video.

• Refer to the tech specs for your iPhone, iPad, or Apple TV, or your smart TV or streaming device to see if it supports playing 4K, HDR, or Dolby Vision videos.

• The latest versions of iOS or iPadOS, macOS, or tvOS.

• An Internet connection fast enough to watch high-quality content.

If you buy or rent a movie from the Apple TV app, you can stream it on the device that you bought it on and any of your other devices, as long as you're signed in to all of your devices with the same Apple ID. Learn what to do if you can't stream movies or TV shows. Your iPhone, iPad, iPod touch, Mac, PC, or Apple TV automatically play the best quality of video available for the device and your Internet connection.

If you purchase or rent a standard definition (SD) video, you can't play higher-quality versions.

If you see a message that your device might not be able to play 1080p (HD) or 4K videos

When you buy or rent a movie or TV show from the Apple TV app, the device that you're using might warn you that it can't play 1080p (HD) or 4K video content. Instead, your device automatically plays the highest-quality version of that video that it can. Your other Apple devices will play the higher-quality version if they're compatible.

Check the quality of your previous purchases

If you previously bought an HD movie from the Apple TV app, you might have access to the 4K, HDR, Dolby Vision, or Dolby Atmos enhancements on a compatible device. If your purchase doesn't have a high-quality version now, it might be added later.

To check the video quality, tap or click a movie in your library. Look at the top of the page for  ,  ,  , or .

Check your Internet connection

To stream high-quality video formats, you need a fast Internet connection. Apple recommends a minimum speed of 25 Mbps for 4K streaming. If your Internet connection isn't fast enough, your Apple devices automatically switch the video quality to a lower-quality version.

You can download a copy of an HD movie to your iPhone, iPad, iPod touch, Mac, or PC, but you can't download a 4K version. You might be able to download Dolby Vision and HDR versions to your iOS, iPadOS, and macOS devices.

If not all these requirements are met, then you would not be able to view content in Dolby Vision.

Cheers!
