"MyCANAL has detected an HDCP compatibility problem" means the app cannot complete a secure playback check. You may see a CANAL+ black screen, hear sound without video, or get the error on only one device, even when no HDMI cable is connected.
This guide helps you identify whether the myCANAL HDCP error comes from the app, the service, or the source-to-display connection. It then walks through five targeted fixes before covering a separate offline option for content you are authorized to access.
Understanding the myCANAL HDCP Compatibility Problem
The myCANAL HDCP compatibility problem does not automatically mean your TV or HDMI cable is defective. HDCP succeeds only when the source, output port, cable, every intermediary device, input port, and display complete a compatible handshake. One incompatible link can cause an error, a blank screen, or an SD quality downgrade.
Use the visible symptom as the first diagnostic clue. The table below can help narrow the problem before you replace any hardware.
| Visible symptom | Likely failing link | First isolation test | Next check |
|---|---|---|---|
| Black screen with audio | HDMI handshake | Reconnect both cable ends | Try another TV input |
| Purple or blank screen | Port or intermediary | Connect source to display | Remove soundbar or receiver |
| Playback forced to SD | Version mismatch | Check another compatible port | Verify the full device chain |
| Failure only in the app | App or account environment | Try a supported browser | Check updates, region, and VPN |
| External-display-only failure | Adapter or display chain | Use the internal display | Test a direct connection |
Phones, Tablets, and Macs Without HDMI
A myCANAL HDCP message can appear on a Mac with no external display, as well as on an iPhone or Samsung phone or tablet. On a Mac, compare the CANAL+ app with a supported browser, update the app and macOS, and check the region, VPN, and proxy settings before buying HDMI hardware.
- App-only playback failure: On a Mac, compare the CANAL+ app with a supported browser. If playback works in one but not the other, focus on the affected app or browser rather than the display hardware.
- Outdated myCANAL app: Old software can result in unwanted issues and glitches. Update the CANAL+ app and the device operating system, then restart the affected app.
- Mirroring or capture activity: Temporarily stop screen sharing, Miracast, or capture-device activity and test playback directly on the device. If you use AirPlay or Google Cast, confirm that both devices and the CANAL+ app meet the current supported-version requirements before treating casting itself as the cause.
- Temporary software glitches: App data or cache buildup can affect playback and streaming. Close the app completely, restart the device, and try another authorized CANAL+ title.
- Region, VPN, or proxy conflicts: A VPN or proxy can change how the service detects the connection or account region. Disable it temporarily and retry from the account's supported region.
If the error appears only on an external display, move to the connected-display checks below. If it also appears on the phone, tablet, or Mac's internal screen, continue with app, browser, operating-system, region, VPN, and proxy checks.
Apple TV and Connected Displays
An Apple TV HDCP error can come from any link between the player and display, including the HDMI port, cable, soundbar, AV receiver, switch, splitter, adapter, projector, capture device, or KVM. Test the Apple TV directly with the TV or display before assuming either endpoint needs replacement.
Before buying a new cable or display, run the full cold-reset sequence in Step 2 with the Apple TV connected directly to the display.
If the direct connection works, reconnect intermediary devices one at a time to identify the failing link. If it does not, test another compatible HDMI input and a cable rated for the required video bandwidth.
After testing the HDMI connection, force-close and reopen the CANAL+ app, then update both tvOS and the app. If the black screen continues, open the CANAL+ video-quality settings and temporarily disable Low-Latency Streaming. For HDR-related failures, also test the HDR option in the app's Expert Settings.
Fix the myCANAL HDCP Problem Step by Step
Work through the following checks in order to isolate and fix the myCANAL HDCP error:
Step 1: Simplify the HDMI Chain
Disconnect soundbars, AV receivers, HDMI switches, splitters, adapters, capture devices, and KVMs. Connect the source directly to the TV, monitor, or projector with one HDMI cable. If CANAL+ plays through that direct connection, reconnect each intermediary one at a time to identify the failing link.
Step 2: Run a Full Cold Reset
- Shut down the display, source device, and any intermediary devices.
- Unplug each device from power and disconnect the HDMI cable at both ends.
- Wait at least 60 seconds.
- Reconnect the source directly to the display.
- Turn on the display first, then power on the source and reopen the CANAL+ app.
Step 3: Verify HDCP Across Every Device
Check the source device, video output, HDMI cable, every intermediary device, TV input, and display for mutually compatible HDCP support. For 4K-UHD playback on Apple TV, CANAL+ specifies an HDCP 2.2-compatible TV and HDMI cable. Requirements may differ for lower resolutions, but every active link must still complete a compatible handshake.
Step 4: Disable VPN or Screen Mirroring
Disable any VPN or proxy and retry from a region supported by the account. As a separate isolation test, stop active screen sharing, Miracast, or capture-device software and play the title directly on the device. If you use AirPlay or Google Cast, verify the supported devices, operating-system versions, and CANAL+ app version before testing the casting connection again.
Step 5: Isolate the Service or Device
Compare the CANAL+ app with a supported browser, then test another CANAL+ title that your account can access. Next, try another streaming service on the same hardware before swapping the cable, source, or display. Do not replace hardware yet if the error is limited to the CANAL+ app, one browser, or one title while another streaming service works on the same setup. That pattern points first to an app, browser, account, region, or title-specific playback issue.
Offline Viewing When Streaming Still Fails
Start with the official CANAL+ app's download feature when a Download option is available for your plan, title, and device. For broader context on CANAL+ streaming and offline options, check which official features are available before choosing a desktop workflow.
KeepStreams for myCANAL provides a separate desktop workflow; it does not repair an HDCP connection. Available for Windows and macOS. For supported titles, it can save MP4 or MKV files at available resolutions up to 4K, with selectable audio and subtitle options, batch downloads, automatic downloads, and metadata. Available quality, HDR, codec, audio, and subtitle options depend on the title and current compatibility. The free trial allows up to three full video downloads within 30 days for this module.
For a USB-based setup, the practical benefit is file compatibility rather than an HDCP fix. You can move downloaded myCANAL videos to a USB drive for playback on a compatible personal device.
Download and install KeepStreams from the official KeepStreams website before starting the desktop workflow below.

myCANAL HDCP Questions
Q1. Can a projector or adapter cause the myCANAL HDCP error?
A1. Yes. A projector, adapter, switch, splitter, AV receiver, soundbar, capture device, or KVM can interrupt the HDCP handshake. Connect the source directly to the display first, then reconnect intermediary devices one at a time.
Q2. Which HDMI cable should I use for an HDCP connection?
A2. Use an HDMI cable rated for the video bandwidth required by your setup. The source, output port, cable, intermediary devices, TV input, and display must also support a compatible HDCP version.
Q3. Can I turn off HDCP to stop the myCANAL error?
A3. CANAL+ does not provide a supported setting for disabling HDCP. Restore a compatible source-to-display connection by checking the source, cable, ports, intermediary devices, and display instead.
Q4. Why does myCANAL fail when other streaming apps work?
A4. Compare the CANAL+ app with a supported browser, then test another CANAL+ title your account is authorized to access. If the error remains limited to CANAL+ or one title, while another streaming service works on the same hardware, focus on the app, browser, account region, VPN, proxy, or title-specific playback path before replacing hardware.
Conclusion
Start with app and browser checks when the error also appears on the device's internal screen. For Apple TV or an external display, test a direct HDMI connection, complete a cold restart, and verify every active device in the HDCP chain before replacing hardware.
If streaming still fails after the connection and service checks, KeepStreams for myCANAL offers a separate desktop workflow for supported content you are authorized to access. It saves local MP4 or MKV files for personal offline viewing on Windows or macOS.
