STATUS_GRAPHICS_OPM_ALL_HDCP_HARDWARE_ALREADY_IN_USE
All HDCP-capable output-protection hardware is already in use
STATUS_GRAPHICS_OPM_ALL_HDCP_HARDWARE_ALREADY_IN_USE is a Windows NTSTATUS value from the graphics/display facility. In this group, the status is tied to protected video output, OPM/COPP compatibility, PVP certificate validation, output-protection hardware, or the monitor configuration path.
OPM can enable protection levels such as HDCP for protected video outputs. This status means the request reached a path that understands HDCP, but the hardware resource needed to apply it is already reserved by other protected outputs or sessions.
The failure is resource contention, not proof that HDCP is unsupported. Multi-monitor, clone, dock, MST, and simultaneous protected-playback scenarios can all matter. Check which protected outputs are already active and whether the display miniport driver has a limited number of HDCP engines or sessions.
What to check
- Enumerate active protected outputs and current HDCP protection levels.
- Test with other displays disabled to separate capability from resource exhaustion.
- Correlate with clone/MST/dock topology and concurrent DRM playback sessions.
