Causes and Fixes of a Roku HDCP Error Detected 020

  1. Check HDMI Cable Connection

  2. Be sure the HDMI cable is plugged in good since a bad connection can cause issues.

    Both sides of the connection can be removed and reinserted to be sure the connection is good.

  3. Replace the HDMI Cable

  4. If the cable has gone bad it can cause issues.

    Replacing the HDMI cable with a known good cable will help to eliminate it as a possible cause.

  5. Disable Auto Adjust Display Refresh Rate

  6. Some Roku devices have an option to Adjust Display Refresh Rate which can be disabled.

    Not all Roku devices have this option, but if yours does, it may solve the problem by disabling it.

    Settings –> System –> Advanced system settings –> Advanced Display Settings.

    If the option is available, disable it and see if the problem clears.

  7. Set Display Type Lower or Auto

  8. Some Roku devices have an option for Display Type, which can be set to auto or a lower resolution.

    Not all Roku devices have a Display Type option, but if yours does, it may solve the problem by disabling it.

    From settings, go to display type and set it to auto or set it to a lower resolution, such as 720p/1080p.

  9. Use a Different HDMI Input Port

  10. Examine the HDMI ports on both the TV and the Roku device.

    The HDMI port may be having an issue, and using another port may help solve the problem.

    For example, if you are using an HDMI 1 port, using HDMI 2 is a quick test to see if the port is not working correctly.

  11. Test Roku on Another TV

  12. If you have another TV to swap out, it can help test if the error is caused by a bad or failing unit.

    If possible, using the Roku on a separate TV will eliminate the TV as the problem.
