While the most common fix is a bad HDMI cable, there are other causes and fixes.
What is an HDCP Error Detected 020?
HDCP (High-bandwidth Digital Content Protection) is a digital copy protection scheme created to stop the copying of videos and audio.
The Roku HDCP Error Detected 020 occurs when HDCP content cannot be played from your device due to these restrictions.
The most common cause of an HDCP Error is a bad HDMI cable or TV resolution set to high.

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