High-bandwidth Digital Content Protection (HDCP) was released in the mid-2000s, contemporaneous with the Apple Cinema Display line of external monitors:
- 23", 30" Apple Cinema Display
- 24", 27" Apple LED Cinema Display
- Apple Thunderbolt Display
Did any of the above monitors support HDCP?
Can a connected macOS system display be queried to determine if it supports HDCP?
This is relevant as many of the adapters needed to connect these monitors to a modern USB-C / Thunderbolt Mac have "HDCP on" and "HDCP off" versions of the same adapter. Which should be used?
How can you determine if an Apple external monitor supports HDCP?
