When displaying content with High Dynamic Range, or HDR, a compatible Roku TV switches into a special HDR mode to achieve the expanded range of contrast and color that creates a more immersive picture. To watch movies, videos or TV shows in this special HDR mode, the title must be available in one of two HDR formats – HDR10 or Dolby Vision™.
When content is in the HDR10 format, all Roku TVs capable of displaying HDR content will switch into the special HDR mode. However, when content is in the Dolby Vision format, only Roku TVs that support Dolby Vision will switch into the special HDR mode. Review the online specifications for the manufacturer of your Roku TV to determine if your model supports only the HDR10 format, or both the HDR10 and Dolby Vision format.
The amount of HDR10 and Dolby Vision content is increasing, but the majority of titles available on streaming services and discs are still limited to Standard Dynamic Range, or SDR, which does not have the enhanced contrast and color information needed to drive the special HDR mode.
What is required to view HDR10 or Dolby Vision content in HDR?
In addition to a Roku TV that can display HDR content, the source from where you plan to watch HDR content must be set up correctly.
- Streaming channels
If you want to watch HDR movies, videos or TV shows on a streaming channel such as YouTube or VUDU, review the requirements for streaming HDR content on your Roku TV. Resources are also available if you need help during general setup of your Roku TV.
- External devices
If you plan to play HDR content from an external device such as an HDR-capable Blu-ray™ player or game console, review the steps for setting up an HDR device with your Roku TV.
The HDMI mode on your Roku TV is set to Auto by default which should correctly detect the capabilities of your external device. However, if for some reason the HDR content from your Blu-ray player or game console is not displayed in HDR, try changing the HDMI mode to HDMI 2.0.
- Roku Media Player
If you wish to use Roku Media Player to view HDR content on your Roku TV, the HDR10 or Dolby Vision formatted content must be stored on a USB drive connected to your Roku TV. Review the guide for using Roku Media Player and the list of supported file types.
Does my Roku TV display all content in HDR?
No. Any content you wish to view in HDR must be available in either the HDR10 or Dolby Vision format depending on which formats your Roku TV supports. These HDR formats specifically provide information for processing the picture with expanded contrast and color range. Movies, videos and TV shows that are in SDR only contain standard contrast and color range information and will not appear in HDR.
How do I know when my Roku TV is displaying an HDR picture?
When you watch HDR10 or Dolby Vision content, your Roku TV detects the correct format and displays an HDR or Dolby Vision logo in the upper right corner of the screen as seen below.
The logo will remain for several seconds after the title starts playing, but you can also find the logo in the Options menu anytime during playback. To check for this, press the Star button on your Roku TV remote and scroll up or down to find the Picture mode setting where the HDR or Dolby Vision logo will appear.
How do picture modes work with an HDR picture?
In addition to the standard picture modes available during playback of SDR content, your Roku TV has tailored picture modes specifically tuned to optimize the image for HDR10 content, or when supported, Dolby Vision content. To see a list of your choices, learn more about using picture modes on your Roku TV.
How do I find HDR movies and TV shows to stream?
In addition to looking for an HDR or Dolby Vision logo while browsing titles within a streaming channel, you can browse the HDR or Dolby Vision row on the 4K Spotlight channel on your Roku TV to find HDR movies and TV shows.
