Disney+ offers a growing library of content for the HDR (or High Dynamic Range) standard, including HDR10. You can find the video formats supported by the title you want to watch in the DETAILS tab on the title overview for each movie or series.
It’s automatic: Disney+ will automatically detect the capabilities of your system and play the content in HDR10, if it’s available.
To run HDR10 content, you'll need an HDR10-compatible device, TV, or display, and a high-speed Internet connection (25 MBs or higher recommended).
Please note these additional recommendations:
To enjoy the highest-quality Disney+ experience: All components should support high-bandwidth digital content, including HDMI cables. Additionally, all components, from the streaming device to the display, along with any intermediate AVR or soundbar, must support HDR10. For 4K Ultra HD and HDR content, external displays should support HDCP 2.2. Consult with the device manufacturer for capabilities of your specific device(s).
Note: Older audio and video components can impact quality and possibly prevent playback entirely.
