An HDCP error on screen means your source device (Blu-ray player, streaming stick, console) and your TV or monitor failed the copy-protection handshake that protects HD content. The fix is usually a cable reseat, power cycle, or version mismatch check.
- All devices in the chain are HDCP-compliant and share the same version (e.g., HDCP 2.2 for 4K)
- You use a certified high-speed HDMI cable plugged into the correct port
- Firmware is up to date on both source and display
- A non-compliant splitter, switch, or capture card sits between the source and display
- HDCP versions mismatch — for example, a 4K source requires HDCP 2.2 but the TV only supports HDCP 1.4
- The cable is loose, faulty, or the devices were powered on in the wrong order
What Is HDCP and Why Does It Block Your Screen?
HDCP (High-bandwidth Digital Content Protection) is a digital handshake that runs every time you connect a source to a display over HDMI, DisplayPort, or DVI. If every device in the chain can’t confirm it’s compliant, the signal is blocked entirely — you see a black screen or an explicit HDCP error message. Netflix, Disney+, Blu-ray, and most 4K streaming apps all require it.

Common Causes at a Glance
| Setup | Works? | Need | Note |
|---|---|---|---|
| 4K source → HDCP 2.2 TV | Yes | HDCP 2.2 cable + port | Use the TV’s HDCP 2.2 labeled port |
| 4K source → HDCP 1.4 TV | No | HDCP 2.2 display | Version mismatch blocks 4K content |
| Source → non-compliant splitter → TV | No | HDCP-compliant splitter | Any weak link breaks the chain |
| Source → capture card → monitor | No | HDCP-stripped path or licensed card | Most capture cards strip HDCP |
How to Fix an HDCP Error
- Reseat the cable. Unplug both ends of the HDMI cable and plug them back in firmly.
- Power cycle in order. Turn off everything, power on the display first, then the source device.
- Try a different HDMI port. Some TV ports are HDCP 2.2 certified — check your TV manual for which ones.
- Remove intermediary devices. Plug directly from source to display and bypass any switch, splitter, or AV receiver temporarily.
- Update firmware. Check for updates on both your streaming device and your TV — HDCP bugs are patched regularly.
- Replace the cable. A worn or cheap cable can fail the handshake even if it passes lower-resolution signals.
USB-C and HDCP Errors
If you’re connecting via USB-C to HDMI — common with laptops and phones — the same HDCP rules apply. Check out our guide on why USB-C to HDMI stops working if you’re hitting errors through an adapter. Also worth reading: whether your USB-C port can connect to HDMI at all, since not every USB-C port carries video.
Bottom line: An HDCP error on screen is almost always caused by a version mismatch, a non-compliant device in the chain, or a loose cable. Start with a full power cycle and direct connection — most errors clear within minutes. If the problem persists, identify which device breaks the HDCP chain and replace or upgrade it.
