HDCP licensing protects high-value movies, TV shows, and audio

Why hdcp causes errors on your hdtv and how to fix it

High-bandwidth Digital Content Protection is a security feature developed by Intel Corporation that requires the use of HDCP-certified products to receive an HDCP-encrypted digital signal.

It works by encrypting a digital signal with a key that requires authentication from both the transmitting and receiving products. If authentication fails, the signal fails.

Purpose of HDCP

The Digital Content Protection LLC, the Intel subsidiary organization that licenses HDCP, describes its purpose as to license technologies to protect high-value digital movies, TV shows, and audio from unauthorized access or copying. The use of HDCP-compliant cables and devices to transmit HDCP-encoded data, in theory, is designed to prohibit the duplication or re-recording of encrypted media by unauthorized devices.

Why hdcp causes errors on your hdtv and how to fix it

Put differently: Years ago, people purchased two video cassette recorders, then chained them in series. You’d play a VHS tape, but the signal from that VCR fed a second VCR with a blank tape set to record. That second VCR then fed the TV, so that you could watch and copy movies simultaneously without difficulty or detection. The use of HDCP devices and cables now precludes this behavior unless you take extraordinary steps to acquire or modify devices to strip the HDCP encoding from a stream.

The most recent HDCP version is 2.3, which was released in February 2018. Many products on the market have a previous HDCP version, which is fine because HDCP is compatible across versions.

Digital Content With HDCP

Sony Pictures Entertainment Inc., The Walt Disney Company, and Warner Bros. were early adopters of HDCP encryption technology.

It’s not easy to pinpoint which content has HDCP protection, but it could be encrypted in any form of Blu-ray disc, DVD rental, cable or satellite service, or pay-per-view programming.

The DCP has licensed hundreds of manufacturers as adopters of HDCP.

How to Troubleshoot HDMI Connection Problems

Connecting HDCP

HDCP is relevant when you use a digital HDMI or DVI cable. If every product using these cables supports HDCP, then you shouldn’t encounter any problems. HDCP is designed to prevent theft of digital content, which is another way of saying illicit recording. As a result, the HDCP standard limits how many components you can connect. Most people won’t mind, but some applications (for example, feeding a bank of TVs at a sports bar) present difficulties.

If all the products used are HDCP-certified, the consumer won’t notice anything. The problem occurs when one of the products isn’t HDCP-certified. A key aspect of HDCP is that it isn’t required by law to be compatible with every interface. It’s a voluntary licensing relationship between the DCP and various companies.

Still, it’s a shock to the consumer who connects a Blu-ray disc player to an HDTV with an HDMI cable only to see no signal. The solution to this situation is to either use component cables instead of HDMI or to replace the TV. That’s not the agreement most consumers thought they agreed to when they bought an HDTV that is not HDCP licensed.

HDCP Products

Products with HDCP fall into three buckets—sources, sinks, and repeaters:

  • Sources are products where the HDCP signal originates. They are the A point in an A-to-B-to-C order of events. Products in this category include DVRs, set-top boxes, digital tuners, Blu-ray players, and DVD recorders.
  • Sinks are products that receive the HDCP signal and display it somewhere. They are the C point in an A-to-B-to-C order of events. Products in this category include TVs and digital projectors.
  • Repeaters are products that receive the HDCP signal from a source and send it to the sink. They are the B point in an A-to-B-to-C order of events. Products in this category include repeaters, splitters, switchers, AV receivers, and wireless transmitters.

For the curious consumer who wants to verify whether a product has HDCP, the DCP publishes a list of approved products on its website.

What Does an HDCP Error Mean?

No firmware upgrade can turn a non-HDCP input into an HDCP-compliant one. If you recently bought an HDTV, you might get an HDCP error when connecting a Blu-ray disc player to your TV via an HDMI cable. In this case, you’d have to choose between using a non-digital cable or buying a new HDTV or Blu-ray player.

What Is HDMI?

HDCP is a purely digital technology that relies on DVI and HDMI cables. That’s why you’ll often see acronyms like DVI/HDCP and HDMI/HDCP. HDMI stands for High-Definition Multimedia Interface. It’s a digital interface that allows your HDTV to render the best uncompressed digital picture possible. HDMI has tremendous support from the motion picture industry. Some of the heavyweights in the consumer electronics industry like Hitachi, Matsushita, Philips, Silicon Image, Sony, Thomson, and Toshiba helped create it.

What Is DVI?

Created by the Digital Display Working Group, DVI stands for Digital Visual Interface. It is an older digital interface that has all but been replaced by HDMI in televisions. There are two significant advantages of HDMI over DVI:

  1. HDMI sends the audio and video signal in one cable. DVI only transfers video, so a separate audio cable is necessary.
  2. HDMI is significantly faster than DVI.

HDCP HDTV Buying Advice

Many recently manufactured TVs are HDCP compliant; however, if you buy an older set, you may not be able to watch movies, play games, or watch Netflix. Regardless of whether your HDTV uses HDMI or DVI, verify that it has at least one input with HDCP support before making a purchase. Not every port on the TV will be HDCP compliant, so read the user manual before you start connecting cables to your TV.

Why hdcp causes errors on your hdtv and how to fix it

At any given point, a large selection of recent movies show up on torrent sites, many of which haven’t even been released yet. For anyone who downloaded, streamed, or torrented these yet-to-be-seen-in-theaters selections, you might have noticed one common theme among all of them: they were stuck at DVD quality.

This is no mistake, of course. But it’s the result of a problem that has plagued Hollywood since the days of Napster: how is it possible that movies make it onto illegal networks before they’re showing at the local movie theater, and why is it still happening in 2016?

The Formats

When pirates upload movies to the Internet, they’ll mark them in one of a few different formats. First, there’s the obvious pick: “CAM”. Short for “camera”, this tag implies that the movie had been recorded by a camera, snuck into the theater and set up during either a very late-night or early-morning showing where the perpetrator is unlikely to be caught.

These are generally the worst quality of the different options as the sound is poor, people can make noise in the theater that interrupts viewing, and getting a perfect 1:1 framing on a shot is basically impossible when you’re trying to take a video on the down-low.

Why hdcp causes errors on your hdtv and how to fix it

Next there’s telesync, which for all intents and purposes is just another cam rip with slightly better audio (usually piped in from theaters that feature auxiliary jacks in the seats for the hearing impaired).

Some movies, however, carry the tag of “DVDSCR”. As you might guess from the acronym, this stands for a “DVD screener”, which is from a DVD copy of the movie sent to film critics, journalists, producers, and other film industry insiders ahead of the Academy’s annual show. Take, for example, this year’s holiday movies, which include the David O’ Russel biopic Joy and Quentin Tarantino’s latest The Hateful Eight. Both were found being distributed on the major torrent sites well before their official release date.

If a studio is pressing the release of a movie right up against the deadline of when the Oscar votes need to come in, often they’ll release their screeners weeks, sometimes even months ahead of the release in order to give judges enough time to deliberate over the quality of any given film.

How Screeners Leak

This is the underlying problem with the screener system. Despite all their noise about employing some of the “latest developments in anti-piracy technology”, the MPAA continues to mail out physical DVD screeners as soon as it comes time for the Oscar/Golden Globe judges to decide a movie’s worth for themselves.

On average, a film will be distributed to anywhere from a dozen to thousands of individual people and media outlets through physical snail mail on a watermarked DVD. But even with all the DRM capabilities in the world, the MPAA maintains that simply watermarking a DVD screener is enough to keep it from being pirated. These are either unseen bits of code in the DVD file itself that can trace where it’s been since being ripped, or even a visual watermark that appears periodically throughout the film indicating whose office the screener originally came from.

A good example of this is back in 2013 when a copy of The Secret Life of Walter Mitty leaked online with the watermark “Property of Ellen Degeneres” splashed across the screen, suggesting that the copy must have come from someone in her show’s production staff. Upon investigation, the MPAA learned that this watermark had actually been added by the hackers themselves in an effort to throw authorities off their scent, a tactic which looks to have worked just as intended.

Until the MPAA and the studios can get their own system straight of who’s leaking what and where, it’s unlikely that these wave of Oscar-voter destined DVDs will be staying off the web anytime soon.

The Problem With Piracy

It’s no secret that even though Hollywood posted its biggest take on record this year (a whopping $11.1 billion thanks to the release of Star Wars), these booming numbers are only propped up by the rapidly inflated cost of an individual ticket.

In fact, the actual number of tickets sold globally (despite rising attendance in emerging markets like China) has plummeted continuously since 1996, and every day theater owners and movie makers alike are being forced to come up with increasingly inventive ways to convince consumers to leave their living rooms and make the trek to their sticky, soda-soaked seats.

Why hdcp causes errors on your hdtv and how to fix it

And although this drop can be partly attributed to the increase in quality we’ve seen in our home theater setups, it’s also because since 1996, the availability of movies uploaded illegally online has exploded, making it easier than ever for anyone with an Internet connection to not only forego buying a ticket, but actually skirt around having to pay anything at all.

When a screener leaks online while a movie is out (or worse yet, before it’s even legally available), this makes it all too tempting for people who wouldn’t normally torrent to seek out different avenues of seeing a film.

Why hdcp causes errors on your hdtv and how to fix it

Andy Baio from has been keeping a detailed spreadsheet of all the major Oscar winners in the past twelve years to track this trend, complete with the date the movie premiered paired with when its screener was leaked online. As you can see, some movies will leak online months ahead of their premiere date, all because the studios and Oscar voters (a large percentage of whom are over the age of 60) can’t be bothered to adapt to any sort of technology that was released past 2005.

If movie studios or the MPAA want to cut down on their losses due to piracy, they’re going to need to rethink the DVD screener system from the ground up. Some industry analysts have proposed that instead of sending these DVDs out into the wild with the hope that everyone keeps their scouts honor, simply hold private screenings for the movies over a personalized stream, possibly in a way that allows the studio to monitor the video output for any signs of ripping or DRM violations.

This way, instead of wantonly distributing the film on DVDs that can be easily stripped of their protections in a matter of minutes, the streams are opened and closed on a controlled channel between the studio and the viewing participant alone. All a voter would need to do is let the studio know when they intend on watching a copy, and a representative (this is what interns were made for, right?) stays with the movie from the opening credits until the last bell is rung. This removes the possibility that a DVD could be stolen from someone’s office and ensures that only a select audience gains access to a film before it’s released in theaters.

No matter what the studio system eventually adopts, it’s obvious that if they want to keep their movies where they belong (in theaters until the Blu-Ray release), they’re going to have to start getting a bit more inventive with the ways they try and woo the Academy to whip up another Oscar in their favor.

Your Roku Stick HDCP unauthorized content disabled and you’re looking for a quick solution?

You have come to the right post!

We have dug deep to find and provide the most efficient solution to the Roku stick unauthorized content issue.

Now, let’s learn what are the most effective methods of troubleshooting your issue.

One of the most efficient approaches in cases like this is to ensure the functionality of the cables within your Roku stick.

If this doesn’t work, try with an alternate HDMI cable or plug the old one into another slot. Also, ensure that your device is directly connected to your TV to avoid possible interference.

Without further ado, let’s see the possible causes of this issue and hopefully learn how to resolve yours.

Why Is HDCP Unauthorized Content Disabled Roku?

Before troubleshooting your issue, it would be appropriate to learn what might interfere with the authorization of your Roku content.

Most of the time, if some of your Roku content is unauthorized, a purple screen might appear.

The purple screen issues might be due to an inappropriate HDMI connection, so take a look at that.

Then make sure that you’re not using any power dividers.

It is recommended to plug the power cable directly into the wall outlet, without anything in-between.

Here are some of the possible causes:

  • Faulty HDMI cable
  • Faulty HDCP cable
  • Power issues
  • TV port issue

Let’s see which of these issues applies to your configuration.

How To Fix HDCP Unauthorized Content Disabled Roku Stick?

The methods below are designed to tighten the circle of possible issues until you find the cause if followed in numerical order.

We recommend checking if your content is authorized after applying each method, to save as much time as possible.

Method #1 Use HDMI Cable

In case you’re not using an HDMI cable on your Roku device and TV, make sure to get one because Roku compatibility addressing some TV models aligns with HDMI.

Of course, you can always check the compatibility of your Roku when it comes down to using an alternate cable, to see what other people say.

When you are installing the HDMI cable on Roku, ensure that all the wirings are plugged all the way in to avoid the purple screen issue.

Keep in mind that if your Roku isn’t working well with the HDCP cable, it might be due to the incompatibility of your device.


Older Roku devices are well-known to only work properly with an HDMI cable, so if you are still experiencing troubles, make sure to try with HDMI.

If using HDMI did not help, let’s try with a different slot.

Method #2 Change HDMI Port

Another thing you can try is to change the HDMI port your cable is plugged into.

This way you will be able to evade any malfunctions within the port and hopefully resolve your issues.

All you have to do is simply unplug the HDMI cable from your Roku device and choose a different port.

This will exclude the possibility of a faulty HDMI port and tighten the circle of possible causes even further.

When you change the HDMI port, you will have to select a different source on your TV.

In other words, if your HDMI cable was plugged into port 1 until now, make sure to check what is the current port and select the corresponding source on your TV.

Still HDCP unauthorized content disabled on Roku streaming stick?

Well, with our next methods we will take the troubleshooting one step further so pay close attention.

Method #3 Power Cycle Roku & TV

A power cycle is a key method addressing power-related issues and it is highly likely to resolve the unauthorized content issue.

Roku users admit that after a firm restart of their devices any temporarily unauthorized content issues seems to disappear, so we figured it is worth trying.

Here is how to perform a power cycle on your Roku and hopefully get rid of the issue:

  1. Turn off both of your devices (Roku and TV.
  2. Unplug the power cable and HDMI of your Roku and TV.
  3. Wait for around 3-5 minutes.
  4. Plug the cables back in.
  5. Turn on your Roku.
  6. Check if the issue is still there.

If you still cannot view the content due to its incompatibility, you might have to consider grabbing a new HDCP cable for your Roku.

Such issues are always related to either the HDMI cable or the HDCP cable you are using, so be aware of that as you proceed further in this post.

Method #4 Use Direct Connection

Another thing that could interfere with your Roku streaming stick’s workability is devices that transmit the connection to your TV.

In other words, we recommend bypassing any transceivers or stereo equipment, as they could also prevent you from viewing the corresponding content.

All you have to do is to connect your Roku streaming stick device directly to your TV.

This way you will be able to determine where the issue is coming from and know what to do if the method doesn’t work.

We recommend disconnecting all devices connected to your TV, connecting only the Roku device, and performing a power cycle.

Roku Stick HDCP Unauthorized Content Disabled Issue Still There…

If none of the methods we have talked about so far didn’t seem to resolve your situation, you might have to contact the support team of Roku for further assistance associated with the issue.

At this point, we guess that the issue comes from the HDCP connection and buying a new cable might get the issue solved.

Where To Purchase New HDCP Cable?

You can find the HDCP cables online for prices starting from $12.

We recommend grabbing a cable shorter than 5 meters for best performance and intermediate level regarding the price.

We assume that you’re familiar with how to connect so the only thing left to do is buying it.

If you have any concerns that the issue might not be coming from the cable, we recommend contacting the support team first to conclude for sure.

Don’t forget to mention everything you’ve done in this post to save yours and us as their time.


We recommend testing your HDMI cable as well on a separate machine to identify if it is working properly.

Bottom Line

We hope that now you know how to troubleshoot Roku stick HDCP unauthorized content disabled and that you’ve learned something new.

After all, the issue could be because of a faulty cable where a replacement would be necessary.

With the advent of affordable HD contents and higher requirements on video playback quality, more and more consumers are switching to purchase, rent, and view movies and TV shows in 720p and 1080p from the iTunes Store (learn to use iTunes Video Converter). But there is a hitch. The HD contents from iTunes Store have a companion HDCP system that sometimes leaves authorized Windows consumers receiving alert messages like:
“This movie cannot be played because it requires Windows 7 and a display that supports HDCP.”
“This movie cannot be played in HD.”
“This movie cannot be played in HD on this display.”
“To play this movie in HD, you must have a PC with a built-in display or have it connected to a display that supports HDCP.”
“To play this movie in HD, you must move the entire window onto a built-in display or a display that supports HDCP.”
“To play this movie in HD, your PC must have Windows 7 and a built-in display or a display that supports HDCP.”

Why unable to play HD video content that requires HDCP? Apple notes that “In order to purchase, rent, and view HD content from the iTunes Store on your computer, you need to have the latest version of iTunes installed, you can download the latest version here. In addition, you will need to have components that support HDCP (High-bandwidth Digital Content Protection) installed on your computer.” In this article, we’ll review what is HDCP, how does it work and how to fix HDCP compatibility issues.

Many video and audio playing devices have the HDCP specification in them. While not all computers are HDCP compatible, some computer manufacturers have turned to HDCP to ensure additional protective measures are in place. Computers fitted with Windows Vista, for example, typically have the HDCP specification. The HDCP spec can be found in some digital video interfaces (DVIs) – a video interface standard found in display devices such as flat panel LCDs. HDCP can also be found in many monitors, game consoles, Blu-ray players that have high-definition multimedia interfaces (HDMI) as well as monitors and home theater systems that have DisplayPort interfaces.

How does HDCP work?
A simple answer is that an HDCP session will result in the exchange of keys between the source and display device. The source device will query the display to make sure that the equipment is HDCP compliant before video is shown. The source device sends a ping to the display device, much like a submarine might do. If the display device doesn’t return the ping to the source device within that period of time then the signal stops.

Let’s say you want to watch a high definition DVD on your HDTV. You connect a Blu-ray disc player to the HDTV with a HDMI cable. The instant you start playing the HDCP-encrypted disc is when the authentication process begins. In this scenario, the source device is the Blu-ray player. The HDTV is the display device. If your television is HDCP-compliant then you would see the movie. If it isn’t then you would either get blank screen or an error message.
Why hdcp causes errors on your hdtv and how to fix it

What this essentially means is that if you use HDMI or DVI cables then you must have HDCP-compatible components in order to see HDCP-encrypted content.

How to fix HDCP compatibility issues?
The only way to fix HDCP compatibility issues is to either replace the product that doesn’t have HDCP with one that does or stop using the HDMI or DVI cable. Since HDCP is digital-only, it doesn’t affect non-digital cables like RF coaxial, RCA, component, s-video, etc.
Why hdcp causes errors on your hdtv and how to fix it

Certified products clearly claim their HDCP compatibility (HDCP Ready), or with the HD Ready stamp.
Why hdcp causes errors on your hdtv and how to fix it

What we would like to see developed is a type of dongle or plug that you can stick into your HDMI port that is nothing more than a HDMI/HDCP or DVI/HDCP converter. That could keep all non-HDCP televisions and devices useful with Blu-ray and other HD digital media.

A quick Google search and it’s easy to understand why many Roku users struggle with the HDCP error. It appears as a warning message on a black screen or as a notification on a purple screen. But why does this message appear and how can you fix it?

Why hdcp causes errors on your hdtv and how to fix it

The following article will help you understand HDCP and offer tried and tested methods to get your streaming gadget up and running. Without much further ado, let’s dive right in.

HDCP Error Disambiguated

HDCP stands for High-bandwidth Digital Content Protection. Developed by intel, this is a common protection standard used by most TV and movie companies.

If you remember the old days when it was impossible to make a copy of some VHS tapes, the HDCP is pretty much the same thing for digital media. It works with HDMI connections and applies to all streaming devices, cable boxes, as well as Blu-ray players.

The important thing is that HDCP 2.2 is necessary to stream in 4K, but more on that later.

Why Does HDCP Error Appear?

The HDCP error appears for two reasons (and can also show up as an error code 020). First, the error occurs if the content you’re trying to stream doesn’t support content-protection technology.

Why hdcp causes errors on your hdtv and how to fix it

The streaming gadget figures out your HDMI link isn’t HDCP compliant and displays the message. On the other hand, the error might pop up if you’re using a faulty HDMI connector or cable. Therefore, you should start by inspecting the cable or the connector.

Chances are you have a spare HDMI lying around your home, so unplug the existing one and reconnect with the new cable. The Roku should automatically pick up the switch and remove the error message.

Fixing the HDCP Unauthorized Issue

When trying to stream Ultra HD 4K content, a purple HDCP screen might appear. In this case, you should inspect the Roku settings for 4K streaming.

Why hdcp causes errors on your hdtv and how to fix it

You need an HDMI 2.0 input that has support for HDCP 2.2. An internet connection that supports Ultra HD streams is also necessary. As a rule, 25 Mbps download or higher should be enough for high definition streaming.

As for HDCP 2.2, all connected devices need to support it. This includes your TV, AVR, soundbar, etc. Otherwise, you won’t be able to stream 4K content and the maximum resolution might not exceed 1080p.

Tip: If you have an older smart TV with multiple HDMI inputs, one of them usually supports HDCP 2.2. Refer to the TV’s manual to determine which input you should use.

Repairing the HDCP Error

A black screen signaling at the HDCP error may occur more often and it’s not linked to high-definition streaming. A simple unplugging and plugging of the cables can help you revive the device. These are the steps to take.

Step 1

Start by unplugging the HDMI cable from all the devices. This goes for the Roku player, AVR, and/or your smart TV. And yes, you need to unplug both ends of the cable.

Step 2

Turn off your Roku and unplug its power cord (both ends again), then repeat with your TV. Now, you can reconnect the HDMI cable and don’t forget to check if the connection is secure and firm.

Step 3

Plug the power cord back in (both your TV and Roku) and be patent until the devices fully boot up. Afterward, try playing the same video again and there shouldn’t be any error message.

Note: The unplugging and plugging action give your Roku a kind of a hardware restart. Doing the software restart doesn’t help because the system still remembers the error and is likely to display it again after the Roku boots up.

Other Fixes

As indicated, one of the quickest and easiest ways to troubleshoot the HDCP error is to use a new HDMI cable. But your options don’t stop at that.

When using an AVR or HDMI switch, you can try to connect your Roku directly to the smart TV. If this doesn’t help, check if the Roku and the connection or cables work on another TV. Should this fail to yield results, hook up Roku to your monitor and play the problematic stream.

The same trick applies the other way around. Remove the Roku from your monitor (if it’s your primary streaming screen) and connect it to the smart TV. Plus, you can also play around with the Display Settings.

Navigate to Settings from Roku’s home screen and choose Display Type. Select different types to find the one that won’t display the error message.

This method might take some trial and error. But once you find the right Display Type, the HDCP error message shouldn’t appear again. Of course, this applies until you switch to another TV or monitor.

Error-Free Roku

Disconnecting everything from the Roku and your TV can be a drag, but it’s the only way to repair the error. The bottom line is that you need HDCP compliant, HDMI inputs and use them as a rule when choosing a smart TV or monitor.

A DHCP error means the server on your network that provides an Internet Protocol address for devices isn’t able to assign your computer an IP address. Because the DHCP setting can break the internet connection, the error can appear in many forms, but the end result is that you can’t access the internet.

Instructions in this article apply to all Windows 10 PCs.

Why hdcp causes errors on your hdtv and how to fix it

Causes of DHCP Errors

Two things can cause a DHCP error. One is the configuration on the computer or device that allows a DHCP server to assign it an IP. The other is the configuration of the DHCP server.

DHCP errors occur when the DHCP server or router on a network cannot automatically adjust the device’s IP address to join the network. This results in a network connection error when you access the internet with a web browser.

What makes DHCP errors so difficult to troubleshoot is that the error message doesn’t always include any mention of DHCP.

How to Fix DHCP Errors

Try these steps until the DHCP error is resolved:

Run the Windows Network Troubleshooter. The easiest way to fix internet connection issues is by letting Windows automatically fix the internet settings. Right-click the network connection icon in the Windows taskbar and select Troubleshoot problems. The network troubleshooter identifies any settings that may cause an internet connection problem. If the DHCP settings caused the error, select Apply this fix to apply any suggested changes.

Why hdcp causes errors on your hdtv and how to fix it

Check the DHCP adapter settings. The DHCP server or router on the network should automatically assign the computer an IP address by default. Still, this option can be disabled, so look in the network adapter settings to make sure it’s enabled.

Check the DHCP router settings. On a home network, DHCP settings in the router manage the IP addresses of devices on the network. Verify that the DHCP beginning and ending addresses match the gateway address.

Contact IT support. On a typical corporate network, a DNS server manages the IP address of devices on the network. All DHCP settings are managed by an IT department. When you have network connection issues, contact your IT help desk.

I am getting the HDCP error message when using You Tube.Only started happening since latest upgrade. I have tried doing your suggested fix. That does not work.

Try this: Go to Settings -> System -> Advanced System Settings -> Advanced Display Settings -> Auto-adjust display refresh rate if it’s set to Enabled, set it to Disabled, Then go to HDR subsampling and set it to 4:2:0 That worked for me, your results may vary.

None of the suggestions posted here corrected my HDCP error . . . so I went back to the original error screen and more carefully read the instructions, which turned out to correct the error.

Here is what I did which made it work:

1) Unplug the power cord to the TV.

2) Unplug the power cord to the Roku

3) Unscrew both ends of the HDMI cable to the TV and to the Roku device.

4) Wait 10 minutes

5) Screw in both ends of the HDMI cable to the TV and the Roku Device.

6) Plug the TV power cable back into the electrical source and turn ON the TV

7) Plug the Roku power cable back into the electrical source and wait for Roku to start up again.

So what is the reason for this? I believe somewhere between the TV powering, the Roku powering, and the HDMI connections are both ends produced a corrupted signal causing the error. But instead of isolating which part of the chain was corrupt, the instructions required a complete shutdown and manual disconnect of all hard wired connections.

Just before I used the above successful instructions, I chose to go through the agonizing (but perhaps required) process of reformatting my Roku as if it were new out of the box. That required me to reinstall it and clone in all of my 280 channels from another Roku I have in the house so as not to lose my channel selections. But that took an hour of downloading, followed by a software update and restart. When this failed to rid me of the Error screen, then I following the seven (7) power unplug and cable disconnect steps listed above and the Error screen no longer appeared.

SO perhaps sometimes to the solution is in front of our eyes with a closer more careful reading of the instructions on the error page.

At this current time, no Cisco video endpoint is able to display local HDCP content or transmit HDCP content.

Sometimes the use of an HDMI splitter between the content source and the codec can overcome these issues.

This has been asked a couple of times before in the forums – see this thread as an example.

Technically, YES, the SX20 is compatible with HDCP as far as the actual specification goes, ie when the SX20 detects HDCP protected content, it will refuse to display or transmit it.

But, that’s probably the opposite of what you’re trying to achieve. You would need to put some other device in between the content source and the endpoint. As per my response in the other thread, here’s a good article on the issue: Why HDCP Causes Errors on Your HDTV, and How to Fix It and it also shows an example device that can do what you are likely wanting to do.
