You need something like this:
<https://www.instructables.com/How-to-Bypassing-HDCP/#:~:text=Step%201:%20Method%201:%20Buy%20a%20HDMI,watch%20content%20and%20HDCP%20error%20is%20gone!>
HDCP stands for High-bandwidth Digital Content Protection. It's a
digital copy protection technology developed by Intel to prevent
unauthorized copying of digital audio and video content as it travels
across connections like HDMI, DVI, and DisplayPort.
Purpose and Function:
Copy Protection:
HDCP encrypts the digital content stream to make it difficult to
copy or record without proper decryption.
Security Measures:
It also verifies that the receiving device is authorized to play
the content, preventing unauthorized access.
HDMI, DVI, and DisplayPort:
HDCP is a key component of these digital interfaces to protect
content during transmission.
Why HDCP Matters:
Preventing Piracy:
HDCP is designed to combat piracy by preventing illegal recording
and distribution of copyrighted content.
Streaming and Content Protection:
HDCP is crucial for streaming services like Netflix and Hulu, protecting
their content during transmission to your devices.
4K and Beyond:
HDCP 2.2 and later versions are essential for supporting the higher
bandwidth requirements of 4K and 8K content.
HDCP Errors:
Compliancy Issues:
HDCP errors can occur when devices or cables are not HDCP
compliant, leading to issues like black screens or video playback failure.
Troubleshooting:
To fix HDCP errors, you may need to ensure all devices and cables in
your setup are HDCP compliant, or try different HDMI ports or cables.
Bypassing HDCP (Caution):
While it's possible to bypass HDCP, doing so is not recommended and may
violate copyright laws.
