Caution: Casting test patterns from an Android screen to a Chromecast converts grayscale levels accurately, but does not provide bit-accurate color patterns. Most other Android devices, such as the Nexus player and HDMI adapters seem to convert all test patterns accurately.

 

  1. Connect the Chromecast device to the desired TV HDMI input.
  2. Turn off "Power Saving Mode" on your Android device. Power Saving Mode can limit the processing power of your device, which might affect the performance of the Cast Screen feature.
  3. Connect your Android device to the same Wi-Fi network as your Chromecast or TV with built-in Chromecast.
  4. Open the Google Home app.
  5. In the top-left corner of the app's Home screen, tap Menu > Cast Screen / audio > Cast Screen / audio.
  6. Select your Chromecast or TV with built-in Chromecast.
