If the Dolby Vision is not working on your Fire TV, then this is the right place to get the required information in detail. Although there might be different reasons behind its bad performance, you can fix them by following some procedures. 

Because of its wide range of colors and 4K resolution, it provides an outstanding viewing experience. However, you may face any of the following issues at some models:

  • Television image appears tinted, the colors are too much brighter, or does not display video
  • The Dolby Vision fails to work on the 4K television
  • Having some audio issues such as audio drops, the audio/video out of sync, noise, etc. 

To study more about how you can make it work on your TV perfectly, read this post and learn a few tricks to deal with its most common issues.

Enable Your Television To Support Dolby Vision

Your TV must be capable of displaying HDR10 or Dolby Vision at 60Hz (50Hz in Europe) to set display automatically. 

Many 4K models offer display at 30Hz (25Hz in Europe), but you can enable Match Dynamic Range in three steps: 

  • Open Settings
  • Tap on Display and Sounds 
  • Choose the Audio/Video Diagnostics  

Dolby Vision is an improved form of HDR available on the latest TV models to let viewers enjoy the most accurate color and contrast details. Many models automatically enable it after checking the capabilities of HDMI connection, but you can also set it manually at any time. 

Take a look at this article if you would like to learn more about Dolby Vision.

Use Correct HDMI Input and Settings

For 4K video quality, you might need to use a different HDMI input according to your television. For instance, some models solely support HDR on either HDMI Input 2 or HDMI Input 3 on some televisions. Therefore, check the user guide to find out which inputs are compatible with 4K and HDR.

It may also be necessary to enable HDR10 or Dolby Vision in the video or HDMI settings on your television along with the correct HDMI input. If there is no such choice with the same name, search for Ultra, Deep, and enhanced video or color options.

Use Appropriate HDMI Cable

An appropriate HDMI cable compatible with HDR10 and Dolby Vision is necessary to match these formats. In this regard, use the HDMI cables that include the Compatible Dolby Vision mark as they can work with a wide range of 4k televisions.

If there is some issue with the HDMI cable, a message will pop up on the screen of your TV that says that the HDMI cable is unable to maintain a stable connection for some reason. You can solve this issue by reconnecting your HDMI cable. Just go to Settings, choose Video and Audio, and then run a test run for two minutes by clicking on the Check HDMI Connection.

If you still encounter connection problems, try this HDMI Cable compatible with the Dolby Vision.

Verify All Other Components

You may be facing issues because a few components, such as a soundbar, HDMI switch, or an audio-video receiver, play on your TV after removing them. You can check the following things if the problem does not appear after the direct connection:

Sound Bar or Receiver

In case you are using the audio-video receiver or the soundbar, you should be checking the settings, connections, capabilities, and the following aspects:

  • Ensure that all the HDMI cables you use are compatible with your TV and Dolby Vision too.
  • Check if your receiver can display 4K and higher video or not. Furthermore, you will need to ensure that your HDMI inputs support HDMI 2.0/HDCP 2.2 and 4K signals.
  • A firmware update is usually necessary for adding HDR10 or Dolby Vision support on some receivers.
  • Once updated, enable Enhanced HDMI in Settings to update video settings on your receiver. 

Now, let’s take a look at additional HDMI accessories.

Additional HDMI Accessories

You may be getting poor HDMI signals due to connecting your television with other accessories, including HDMI splitters, boxes, etc. If the issue resolved after removing them, check their details provided by the manufacturer to determine whether they support Dolby Vision, HDR, or 4K videos or not. 

When connecting your TV with the Audio/Video Receiver or the soundbar, use cables that are capable enough to run the Dolby Vision or HDR formats. It might be convenient for some folks to rely on their existing ordinary choices, but a slight difference would affect the entire quality. An incompatible accessory will ruin your viewing experience, so buy the products that support Dolby Vision. 

Conclusion

It was a quick guide to let you get enough information to make the Dolby Vision work on your TV without any issue. If you still fail, then check whether your current model supports it or not. Never forget that many brands that are famous for offering high-tech devices do not implement Dolby Vision. 

The User Guide of your TV can further help you know about the capabilities and other information to get the real benefits of Dolby Vision.
