Visualizing: HDCP 2.2: The Secret Cause of Black Screens
HDCP (High-bandwidth Digital Content Protection) is a 'handshake' between your device and your TV. If they don't agree, you get a black screen or a 'HDCP Error'.
HDCP 2.2 vs 1.4
HDCP 2.2 is required for 4K HDR content. If you use an old HDMI 1.4 switch or a cheap non-certified splitter, it will break the chain, and your streaming app will downgrade to 1080p or fail entirely.
