About 4K, HDR, HDR10+ and Dolby Vision on your Apple TV 4K

Find out how to set up your Apple TV 4K for the best 4K, HDR, HDR10+ or Dolby Vision experience.

Apple TV 4K is built to take full advantage of 4K HDR so that you can enjoy TV in the highest quality ever. Apple TV 4K supports the following 4K display formats:

  • 4K Dolby Vision: used for 4K TVs that support Dolby Vision HDR to display video dynamically, on a scene-by-scene basis and with an even more accurate range of colour, contrast and luminance than standard HDR.
  • 4K HDR10+: used for 4K TVs that support HDR10+ to display video dynamically, on a scene-by-scene basis and with an even more accurate range of colour, contrast and luminance than standard HDR.*
  • 4K High Dynamic Range (HDR): used for 4K TVs that support HDR to display video with a broader and more accurate range of colour, contrast and luminance than SDR.
  • 4K Standard Dynamic Range (SDR): used for 4K TVs that don’t support HDR, HDR10+ or Dolby Vision to display a standard range of colour, contrast and luminance. 

* HDR10+ is a supported format only on Apple TV 4K (3rd generation).

Get the best picture

Apple TV 4K is designed to provide the best viewing experience based on the capabilities of your 4K TV. In some situations, you may experience issues or need to check your configuration manually. These issues may include:

  • The image on your TV is tinted, the colour is too bright or it has intermittent or no video.
  • You're seeing intermittent static, snow or sparkles on the screen.
  • Unable to use HDR or Dolby Vision on a supported TV.
  • You're experiencing audio issues, such as audio drops, noise or audio/video that is out of sync.

If you're experiencing any of these issues, make sure your Apple TV is running the latest version of tvOS. Then follow the steps below.

Make sure your TV supports HDR10, HDR10+ or Dolby Vision

In order for Apple TV 4K to automatically set your display format to HDR10, HDR10+ or Dolby Vision, your TV must be able to display HDR10, HDR10+ or Dolby Vision at 60 Hz (50 Hz in Europe). Apple TV 4K can display these formats at 30 Hz (25 Hz in Europe), but you’ll need to enable Match Dynamic Range in Settings > Video and Audio > Match Content. If you aren’t sure which formats your TV supports, check the user manual for your TV.

Use the correct HDMI input and settings

Depending on your TV, you may need to use a different HDMI input on your TV for high-quality 4K or HDR video. For example, some TVs only support HDR on HDMI input 2 or HDMI input 3. Check the user manual for your TV to identify which inputs support 4K and HDR.

In addition to using the correct HDMI input, you may need to enable HDR10, HDR10+ or Dolby Vision in the video or HDMI settings on your TV. In some cases, the setting may not refer directly to HDR10, HDR10+ or Dolby Vision. Examples include Ultra, Deep or Enhanced video or colour.

Check your HDMI cable

If there’s an issue with your HDMI cable, you may see a message on your TV that says your HDMI cable may be having trouble maintaining a stable connection. If your Apple TV 4K is connected to a 4K compatible TV, you can run a two-minute test to check your HDMI cable connection. Go to Settings > Video and Audio and select Check HDMI Connection.

4K video, especially HDR10, HDR10+ and Dolby Vision, requires an HDMI cable compatible with these formats. Apple recommends HDMI cables that have the Compatible Dolby Vision mark because they've been tested with Apple TV 4K and a wide range of TVs. An example is the Belkin Ultra High Speed HDMI Cable.

If you are still experiencing issues with your HDMI cable connection, check all your connections and make sure your HDMI cable has the label "Compatible Dolby Vision".

Check other components

If you're using other components, such as an audio video receiver, HDMI switch or sound bar, temporarily connect your Apple TV 4K directly to your TV. If the issue doesn’t occur when its connected to your TV directly, check the following:

Receiver or sound bar

If you’re using an audio video receiver or sound bar, you should check its capabilities, connections and settings, as well as the following:

  • Verify that your receiver is capable of displaying 4K and higher video, and that you’re using HDMI inputs that support 4K and HDMI 2.1.
  • Receivers that support HDR10, HDR10+ or Dolby Vision often require a firmware update to add this support.
  • Check the video and HDMI settings on your receiver after updating, as you may need to enable enhanced HDMI in settings.
  • Make sure all the HDMI cables connecting your Apple TV 4K to your TV and receiver are compatible with 4K and HDR video.

Other HDMI accessories

HDMI switch boxes, HDMI splitters or other accessories that connect your Apple TV 4K to your TV may interfere with the HDMI signal. If the issue has been resolved after removing these accessories, check with the manufacturer to determine whether they support 4K and HDR video.
