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.
