_DXGKMDT_DPCP_PROTECTION_LEVEL enumeration

Description

The DXGKMDT_OPM_DPCP_PROTECTION_LEVEL enumeration indicates the protection levels for a protected output that supports DisplayPort Content Protection (DPCP).

Constants

`DXGKMDT_OPM_DPCP_OFF`

Indicates that DPCP does not protect the output's signal.

`DXGKMDT_OPM_DPCP_ON`

Indicates that DPCP protects the output's signal.

`DXGKMDT_OPM_DPCP_FORCE_ULONG`

Forces this enumeration to compile to 32 bits in size. Without this value, some compilers would allow this enumeration to compile to a size other than 32 bits. You should not use this value.

Remarks

DPCP protects digital video signals from DisplayPort output connectors. For more information about DisplayPort, see the DisplayPort article.
