Your SHIELD TV supports 4K Ultra HD (3840 x 2160p) resolution content with HDR10 or Dolby Vision, from many apps.
To ensure that your SHIELD TV is optimized for 4K video output, keep your device updated with the latest system software.
Watching 4K content from SHIELD TV requires a 4K display with HDMI 2.0 and HDCP 2.2 support. Make sure SHIELD TV is connected to an HDMI input that supports HDCP 2.2. Consult your 4K display's user guide to find the correct HDMI port to plug SHIELD TV for watching 4K content.
Consider using the HDMI-UHD port for 4K support. Some TVs by default have UHD input disabled in TV settings, so please make sure that UHD is enabled in the settings for your TV for this input.
Your SHIELD will automatically set to a HDR10 capable display mode when detected.
If you own a Dolby Vision compatible display at 4K resolutions with 60Hz refresh rate, enable Dolby Vision by selecting Settings > Device Preferences > Display & Sound > Dolby Vision
If you are unable to enable “Dolby Vision”, your HDMI cables may be the issue. Try replacing them with higher quality cables and try again.
If your TV supports 4K Dolby Vision at lower refresh rates, you can change your display mode at Settings > Device Preferences > Display & Sound > Advanced display settings > Custom display mode and select any mode labelled “Dolby Vision Ready”.
| Warning: | Selecting lower refresh rate display modes will cause home screen and app navigation to appear slow. |
Some HDR TVs do not have HDR output enabled by default for HDMI. To enable HDR output from SHIELD, refer to your TV owner's manual. Here are the settings for some of the common TVs:
