Are you using a Roku device and seeing an HDCP error all of a sudden? Have you connected your older HDTV with your Roku device by using the HDMI cable and are unable to play the video (Interlink here with the “HBO won’t work on Roku” page when published)? Well, you are in luck as we’ll explain why your Roku device is not working and what steps you can take to solve this issue.

The HDMI cable has a built-in anti-piracy protocol standard, However, this protocol has a poor track record for privacy protection and only contributes to breaking the user viewing experience.

This article will guide you on why the HDCP error occurs with the HDMI connections and how you can fix the error by resetting the HDCP protocol or bypassing the HDCP error.

Why Is My Roku HDMI Not working?

Your Roku HDMI might not be working with your TV due to the following reasons.

  • HDMI cable does not have a firm connection to the TV set or the Roku device
  • You are not using the certified 8K 48 Gbps HDMI cable that is compliant with the HDCP protocol
  • You don’t have a 4K HDMI input port on your TV
  • The auto-adjust display refresh rate(Interlink here with Roku 020 article) is enabled
  • HDMI port on the TV or the Roku device is damaged
  • HDMI cable is damaged or needs to be replaced

How Do I Bypass HDCP Error?

If you want to see HDCP content through a Roku device on a non-HDCP TV, you can do it by the following methods.

Buy A Splitter

The first method to bypass HDCP error is to buy and use a splitter. The splitter will strip the HDCP protocol from the non-HDCP devices. You will need an additional HDMI cable for this method to work.

  • First, connect the Roku device to the HDMI splitter with the HDMI cable
  • Now use the second HDMI cable to connect the splitter to your TV
  • Restart both the devices and verify if the HDCP error is gone

Use An Analogue Cable

The second option is to use an analog cable but the image quality will be compromised a little. To do this:

  • Connect the analog cable instead of the HDMI cable to your Roku device
  • Connect the other end of the analog cable to your TV
  • Restart both devices and enjoy HDCP content

How Do You Fix This Display That Does Not Support HDCP?

It can be very frustrating to see the “Display does not support HDCP” error on your TV while trying to watch your favourite program through the Roku device. The error can pop up due to numerous reasons. However, you can fix the issue by implementing the following general troubleshooting methods.

Check All Your Devices

A faulty HDMI cable can generate an HDCP error. Therefore, you need to check whether the HDMI cable is working properly or not. Simply insert the HDMI cable into another device. If the cable is malfunctioning, buy another one and connect it to your Roku device and your TV to fix the error.

Check Your Roku Device

If there is a technical issue with your Roku box because of some damage, it won’t react to the HDCP command through the HDMI cable. If this is the case, contact Roku support to fix your Roku device or to get a new one.

Inspect Your TV

Sometimes, any damage to your TV set can initiate the HDCP display error. Therefore, check any signs of physical damage to the TV set and if all seems okay, rule out TV software issues.

To do this, go to your TV manufacturer website and type in your TV model number into the search box and hit Enter. Next, click on Downloads and then download and install the latest software for your TV set.

Finally, restart both Roku and your TV set and see if that method fixes the HDCP display error.

How Do I Reset HDCP?

If the above method fails to fix the Roku HDCP error that happens all of a sudden on your TV set, you may need to reset the HDCP protocol. To do this, perform a power cycle on your TV and the source device.

  • Power off both the Roku device (Or restart Roku from the Main Menu) and the TV set from the main wall socket
  • Wait for 10 seconds and disconnect the HDMI cable from both devices
  • Now wait another few seconds and reconnect the HDMI cable
  • Turn on your Roku device and TV from the main wall socket

This procedure will initiate a fresh HDMI and HDCP handshake authentication process that can fix the HDCP display support error.


We hope that by now you have fixed the common Roku HDCP error that pops up all of a sudden and displays error text such as the “Display does not support HDCP error” while playing content through your TV set. If the error persists, remember to use the HDCP complaint cable or buy a display that supports the latest HDCP protocol. Good Luck!
