In addition, some 4K Ultra HD TVs and some Roku streaming players support a feature called HDR (High Dynamic Range) for a wider range of colors and brightness. Roku players that support HDR, use the HDR10 standard. You can use the Roku device comparison chart to determine which other players support HDR.
HDMI 2.0 and HDCP 2.2
To successfully stream 4K HDR content, all devices connected to your compatible Roku device must support HDMI 2.0 and HDCP 2.2. This includes your TV, an AVR or sound bar, and any other devices connected in between. If even one device does not support HDMI 2.0 and HDCP 2.2, then the 4K HDR movie or TV show will not appear in HDR and can only be viewed in a lower resolution, such as 720p or 1080p.
HDCP 2.2 is a copy and content protection standard required by the TV and movie industry. Some 4K HDR TVs may only support HDCP 2.2 on a single HDMI input. Learn what to look for when trying to identify an HDMI input that supports HDCP 2.2.
Configuring your TV for HDR
Your 4K HDR TV must be configured correctly to display HDR content. Many TVs that support HDR do not enable HDR by default. Below are the settings for enabling HDR on some of the most common TVs. For other TVs, please refer to the documentation or online user guide. Note that the HDR settings on some TVs are specific to each HDMI input. Please make sure to change the settings specific to the HDMI input to which your Roku player will be connected.
- Samsung HDR TVs: Menu > Picture > Picture Options > HDMI UHD Color > On > Restart
- LG HDR TVs: Home > HDMI > Settings > Advanced > Picture > HDMI ULTRA DEEP COLOR > On > Restart
- Sony HDR TVs: Home > Settings > External inputs > HDMI signal format > HDMI [select the Roku player input] > Enhanced mode (TV will reboot)
After the connections are made, power on your Roku player and complete Guided Setup using instructions from the appropriate article on the Setup page.
