Why Protected Content Shows Black Screen
Understanding HDCP copy protection and why Netflix, Blu-ray, and some content can't be captured. Legal workarounds and alternatives.
The Problem
When playing Netflix, Blu-ray movies, or certain streaming content, your capture shows a black screen even though source displays correctly on TV.
The Solution
This is HDCP (High-bandwidth Digital Content Protection) - intentional copy protection. Content cannot be captured by design. Use HDCP-compliant sources or record different content.
Step-by-Step Instructions
Understand: HDCP is copyright protection mandated by content owners
Magewell devices correctly implement HDCP - they won't capture protected content
Protected content includes: Netflix, Disney+, Amazon Prime Video, Blu-ray discs, iTunes movies
Non-protected content works fine: Your own videos, gameplay, cameras, presentations
For gameplay capture: Enable 'Allow Game Capture' in console settings (PS5/Xbox)
For screen recording: Use software screen capture (OBS Display Capture) instead of HDMI
For movie reviews: Use non-DRM sources or screen-recorded clips (fair use considerations)
HDCP strippers/splitters are available but may violate DMCA in some jurisdictions
Legal solution: Contact content owner for permission and non-HDCP sources
Pro Tips
- This is not a device defect - all compliant capture devices behave this way
- Gaming consoles allow gameplay capture but protect streaming apps (Netflix on PS5)
- PC screen capture bypasses HDCP as it captures before HDCP encryption
- Cameras and local video files have no HDCP - capture freely
- HDCP only affects HDMI - analog inputs (Component) and SDI don't have HDCP
