If you’re experiencing HDCP errors on your television, there are a few things you can do to fix them. First, make sure that your TV is up to date with the latest firmware. If it’s not, you can update it by going to the TV’s website and downloading the latest version. Second, make sure that your HDCP settings are correct. If they’re not, you may be experiencing problems with HDCP compliance. Third, try changing your HDMI cables. If that doesn’t work, then you may need to replace your TV altogether. Finally, if all of these solutions don’t work and you still experience HDCP errors, then you may need to get a new television or upgrade your firmware.
HDCP is an anti-piracy protocol built right into the HDMI cable standard, but it doesn’t actually work very well, and breaks the viewing experience. Read on as we explain how HDCP works, why it breaks your TV, and how you can fix it.
What Is HDCP?
HDCP (High-bandwidth Digital Content Protection) is a form of Digital Rights Management (DRM). DRM protocols are designed to protect content creators and distributors against piracy. Different companies and industries use different protocols, but the basic premise is the same: DRM locks purchases you make to you and your devices. When you buy a movie on iTunes and can only play it on devices with your account, you’re experiencing DRM.
Content creators and distributors should be afforded some protection, since it’s expensive to create and distribute content. The trouble is that DRM typically makes life more difficult for honest paying consumers—and in many cases outright breaks the experience—while not really doing much to deter piracy. This is the kind of trouble we run into with games that require authorization servers to run; if the company goes under so does the authorization server and suddenly the game won’t run.
In the case of the HDMI standard and digital video, the HDCP DRM standard causes an unfortunate number of headaches for regular old consumers just trying to enjoy their televisions and engage in other legitimate activities.
HDCP was developed by Intel and is used not just with HDMI, but with a variety of digital video standards like DisplayPort and Digital Visual Interface (DVI). It provides for an encrypted connection between a content outputting device (like a Blu-ray player, cable box, or streaming device) on one end and a receiving device (like an HDTV or audio-video receiver) on the other end.

Where HDCP Breaks Down
Although HDCP’s underlying encryption and protocols are sophisticated and outside the scope of this article, the basic premise of how it works is quite simple. There is a licensing body that issues licenses for HDCP devices. Each HDCP-compliant device, like your Blu-ray player or Xbox, has a license and the ability to talk to the receiving device on the other end of the HDMI cable.
The outputting device says “Hey display! Are you HDCP compliant? Here is my license, show me your license!” The display (or other HDCP compliant device) returns with “Why yes, I am legit! Here is my license!” When that process works, it happens within a thousandth of a second and you, the consumer, never even notice. You power on your Blu-ray player or DVR, it makes nice with your HDTV, and you live a happy life never knowing what HDCP even is.
Unfortunately, however, there are a host of situations where HDCP gets in the way of consumers doing perfectly legal things with their devices and content. If any device in the chain is not HDCP compliant, the video stream will fail.
For example, if you have an older HDTV set that is not HDCP compliant then you cannot watch any HDCP compliant content on it. If you plug in your HDCP-compliant device to a non-compliant device, you’ll either see a blank screen or an error message like “ERROR: NON-HDCP OUTPUT,” “HDCP unauthorised,” or simply “HDCP ERROR.”
Want to turn that old monitor with integrated speakers into a cheap little video box with a Chromecast? Sorry, there’s a very good chance that old monitor (despite having an HDMI port) is not HDCP compliant. You won’t be streaming anything to it unless you want to dedicate a whole computer to the project.
Want to record your video game sessions or stream them live? It’s hit or miss. Console makers have gotten better about recognizing that players want to record and stream their content, but HDCP is still problematic. The Sony Playstation lineup is a perfect example of this problem. While Sony did release an update in 2014 for the PlayStation 4 that unlocked HDCP while actually playing the game, they can’t provide the same update for the PlayStation 3 because the HDCP output is locked at the chip level in the PS3. Their only advice is to buy a capture device that supports component cables and use those instead of HDMI.

There’s nothing illegal or unethical about hooking a Blu-ray player up to an old TV, trying to recycle an old computer monitor into a little Chromecast-powered streaming station, recording and streaming your video game play, or trying to capture menus and screen shots to write tutorials and guides, but thanks to a flawed DRM protocol anyone who wants to any or all of those things is left in the dark.
How to Fix Your HDCP Problem
Absolutely no one should have to buy a new television set, upgrade their perfectly fine audio-video receiver, or otherwise spend significant piles of money to solve a problem that shouldn’t exist in the first place. Unfortunately, the only official way to comply with HDCP is to buy an HDCP-compliant device.
The most absurd thing about the HDCP protection scheme is that there is no HDCP-compliant way to circumvent it for legitimate use cases. There are zero methods endorsed or supported by the agency in charge of HDCP that help consumers in any way if they have older equipment or a legitimate non-piracy need to interact with an HDCP-compliant device.
To add further insult to injury, the HDCP standard has been compromised for years now. Manufacturers continue to pay for licenses and include HDCP in their products not because it’s actually helping to stop piracy, but because they don’t want with the licensing agency and the anti-piracy lobby. So what can you do to deal with the outdated and now compromised mess that is HDCP?
Short of buying a new television or giving up on your video game project the only way to deal with your HDCP compliance problem is to buy a cheap HDMI splitter that ignores HDCP requests.
We really wish we were kidding, but that’s the secret media center ingredient that has helped thousands of consumers and the very same secret ingredient that we use here at How-To Geek when we need to take screenshots of an on-screen menu to showcase a product we’re reviewing.
To use the splitter, simply put it between the output and display device. For example, say you have a simple setup where you just want to plug a Chromecast into an old monitor. Instead, you’d plug the Chromecast into the input on your HDMI splitter, and then use an HDMI cable to connect the output on the splitter to your display. If you have a new audio-video receiver that doesn’t play nice with your old HDTV, plug all your HDMI devices into the receiver and then place the HDMI splitter between the receiver and the display.
Here’s what our attempts at capturing good screenshots for our tutorials looked like before dealing with the HDCP problem.
You can see how such a screenshot would be pretty useless for our purposes; nobody wants to see what the menu of a device they’re considering purchasing looks like with a big ugly error message across the back. In this example, even though we’re using a capture tool, you’re seeing exactly what a home user with a non-HDCP-compliant HDTV would see: the non HDCP-protected part of the video (the menu bar and pause button) is passed through, but the actual content is removed.
Here’s what the exact same screenshot looks like, but with the signal passed through the splitter to strip away the HDCP nonsense.
You can imagine, given our love for clever and thoughtful solutions to the problems that plague people, how absurd we find it that the solution to a problem which shouldn’t even exist is “buy an out-of-spec device that ignores the faulty protocol.” Nonetheless, that’s exactly the situation consumers find themselves in and thankfully, whether through poor or intentional design, there are products out there that get new media players talking to old HDTVs.
