What should I do if I see a “HDCP Error Detected” message or a purple screen?


If your Roku® streaming player detects that the HDMI® link with your TV or audio/video receiver (AVR) does not support the copy and content protection technology known as HDCP, it may display a “HDCP Error Detected” message with error code 020, or it may display a purple screen.

Aside from a TV or AVR that does not support HDCP, this issue may also be the result of another problem such as a faulty HDMI cable or HDMI connector. This article explains how to troubleshoot and resolve the issue when an HDCP error is detected when using your Roku player.

What is HDCP?

HDCP is the copy and content protection standard used by the movie and TV industry. Copy protection/content protection has been around for a long time, and in its early stages was what prevented you from copying commercial VHS tapes. The latest copy protection technology is called HDCP (High-bandwidth Digital Copy Protection), and it is used on HDMI connections for digital devices like Blu-ray™ players, cable boxes and Roku streaming devices.

If you are streaming 4K or 4K HDR content on these devices, a newer version of the copy protection technology, known as HDCP 2.2, is required. Learn more about HDCP 2.2 and why it is important to playing 4K or 4K HDR content.

To resolve the "HDCP Error Detected" issue, try these steps: 

  1. If you are trying to stream 4K Ultra HD content when you see the purple screen, review the instructions for setting up your Roku player for 4K. Go to the next step if you continue to see a "HDCP Error Detected" message or a purple screen.
  2. On both your Roku player and your TV or AVR, unplug each end of the HDMI cable.
  3. Power off your TV and unplug its power cord.
  4. Remove the power cord from your Roku player.
  5. Reconnect both ends of the HDMI cable, making sure each connector is attached firmly and securely.
  6. Reconnect the power cord to your TV and your Roku player and wait for both devices to power on (you may also need to press the power button on your TV remote). 
  7. Try viewing the video again.

If the above did not resolve your issue, try these additional suggestions:

  • Try a different HDMI input on your TV.
  • Try using a different HDMI cable (less than 6 feet if available), just to make sure the cable you are currently using does not have any defects.
  • If you are using an HDMI switch or AVR, try connecting the Roku player directly to the TV.
  • Try another TV, if possible.
  • If you are using a computer monitor, try using a TV, if possible.
  • Try using different Display Settings on your Roku player. You can find these settings under Settings > Display type.
  • If this is the first time you are seeing the "HDCP Error Detected" message or purple screen after setting up your Roku player, ensure that your TV and/or AVR supports HDCP. Contact your equipment manufacturer for more information.
