4K (60p or 120p) picture from an external device is not displaying normally on an Android TV

To view 4K content on your television properly, it's important to know the video signal type (24p, 30p, 60p or 120p) and the bandwidth format (Enhanced format (up to 18Gbps) or Enhanced format (18Gbps or above)) capability of the HDMI® inputs on your TV. To find the input video signal information and the HDMI cable requirements for your TV, refer to the What functions are supported on each of the HDMI terminals? article. You can then acquire the proper HDMI cable to connect your devices and set the HDMI input to the proper signal input selection.

Follow these steps depending on your model:

1. Open the Settings screen.
   • Using the Quick Settings button (For models released in 2019 or later)
     1. On the remote control, press the (Quick Settings) button.
     2. Select Settings.
   • Using the HOME button
     1. On the remote control, press the HOME button.
     2. Select Settings
2. Open the HDMI signal format settings.
   • Select Channels & Inputs → External Inputs → HDMI signal format.
   • Select Watching TV → External Inputs → HDMI signal format.
   • Select TV → External Inputs → HDMI signal format.
3. Set to Enhanced format, Enhanced format (Dolby Vision), Enhanced format (4K120, 8K) or Enhanced format (8K), depending on your TV model.

If the signal is in enhanced format, picture or sound from external devices that do not support 4K may not be output normally. In such cases, change HDMI signal format to Standard format or switch the HDMI cable to an input for signals in standard format.
