Apple TV 4K micro-console is geared to deliver the best 4K HDR experience to let users the highest quality of TV. There are several 4K display formats supported by Apple TV 4K:
- SDR, or 4K Standard Dynamic Range – meant for 4K televisions without HDR10 or Dolby Vision support.
- HDR, or 4K High Dynamic Range – meant for 4K televisions with HDR support rendering videos with a wider color range and luminance.
- 4K Dolby Vision – meant for 4K televisions with Dolby Vision HDR support rendering videos with a wider color range and luminance adapted for your TV.
How Identify the Display Format Supported by Your Apple TV 4K?
The first time you hook up your Apple TV 4K to a 4K television with Dolby Vision or HDR10 support, you will be offered to perform a brief display test.
Use the on-screen prompts to check if the picture is clear. If the test fails, Apple TV 4K will go back to the previously used configuration.
To verify the currently used Apple TV 4K video mode, access Settings → Video and Audio. Next, select a display format.
How to Get the Finest Picture?
If you experience issues with the picture quality on your Apple TV 4K, check your configuration. Also, ensure that you have the latest version of tvOS installed on your Apple TV, and follow these steps:
- Check if your television has HDR10 or Dolby Vision support.
The television used with Apple TV 4K has to display Dolby Vision or HDR10 at 60Hz (in Europe – 50Hz). If the television capabilities are limited to 30Hz (in Europe – 25Hz), enable Match Dynamic Range. Go to Apple TV 4K Settings → Video and Audio → Match Content. To verify the formats supported by a specific television, see the user guide.
- Check if the HDMI input and configuration are correct.
To learn the type and configuration of the HDMI input on your television, see its user guide. Depending on the television model, the used HDMI inputs may differ. Also, see if you can switch on the HDR10 or Dolby Vision in the video or HDMI settings on a given television. In specific cases, the settings wording may look like Ultra, Enhanced, or Deep video or color.
- Perform television software updates.
If you have picture quality related issues, see if your television has the latest software version. The majority of 4K televisions and receivers can get software updates via Ethernet or Wi-Fi network. See the television’s user manual for reference.
- Check the HDMI cable compatibility.
Dolby Vision and HDR10 video formats require a compatible HDMI cable. HDMI cables with Compatible Dolby Vision indication are compatible with Apple TV 4K and a vast selection of televisions (for instance, Belkin Ultra High Speed HDMI Cable).
- Check HDMI accessories and other components.
In case you have other components (an audio HDMI switch, video receiver or sound bar) plugged into your Apple TV 4K, disconnect all of them. Connect the Apple TV 4K console to your television to see if the problem persists. If it doesn’t check the Receiver or sound bar settings. Also, check the settings and capabilities of all extra components.
If you’re using HDMI accessories like switch boxes or splitters, they might hinder the HDMI signal. Try to unplug the above devices to see if the problem stays. Also, consult with the manufacturer to see if they have the support of 4K and HDR video.
How to Enable the Frame Rate and Dynamic Range Matching?
Apple TV 4K can switch the display format to match the initial dynamic range and frame rate of the video content in tvOS 11.2 and later. It is possible to dynamically improve the output quality without using the highest capability of a given television.
To activate this Apple TV 4K feature, access Settings → Video and Audio → Match Content, and select one of the following:
- Match Dynamic Range: Enable to match the Apple TV 4K output to the initial dynamic range of the viewed video.
- Match Frame Rate: Enable to match the Apple TV 4K refresh rate to the initial frame rate of the viewed video. Note: this applies to 24fps film-based content as well as international content.
