What does HRESULT 0xC026234F (ERROR_GRAPHICS_INVALID_COPYPROTECTION_TYPE) mean?

ERROR_GRAPHICS_INVALID_COPYPROTECTION_TYPE

Interpret the result in its owning layer: graphics invalid copyprotection type

The useful interpretation of ERROR_GRAPHICS_INVALID_COPYPROTECTION_TYPE (0xC026234F) starts at the vidpn boundary: the requested copy-protection type is invalid for the present path descriptor. In practical terms, inspect VidPN path copy-protection selection before changing application-wide graphics settings.

Keep VidPN metadata separate from OPM negotiation

The copy-protection field in a present path must be a recognized type; it is not a shortcut for forcing HDCP, ACP or another OPM protection level. Record the connector, content classification, requested path field and the actual OPM capability result. In the A/B test, submit a documented neutral or supported path value and negotiate protection through the protected-output interface separately. This prevents a malformed enum from being misdiagnosed as an HDCP hardware failure.

ERROR_GRAPHICS_INVALID_COPYPROTECTION_TYPE: VidPN handles and subobjects are generation-bound. For ERROR_GRAPHICS_INVALID_COPYPROTECTION_TYPE, A monitor hot-plug, docking action, session switch or mode commit can invalidate an otherwise well-formed cached object. For ERROR_GRAPHICS_INVALID_COPYPROTECTION_TYPE, the built-in one-line message identifies the immediate result; diagnosis also needs the producing API, object ownership and the display generation current at the time.

Capture before recreating objects

For ERROR_GRAPHICS_INVALID_COPYPROTECTION_TYPE, preserve the unsigned HRESULT, symbolic name, first failing API and timestamp in one record. If cleanup later fails too, keep that secondary result separately from ERROR_GRAPHICS_INVALID_COPYPROTECTION_TYPE.

Reproduce one variable at a time

1. Freeze the ERROR_GRAPHICS_INVALID_COPYPROTECTION_TYPE generation. Record protection enum, connector, content type, OPM capability and target mode. Before diagnosing ERROR_GRAPHICS_INVALID_COPYPROTECTION_TYPE, do not resize, hot-plug, recreate or release the object under examination.
2. Run the narrow ERROR_GRAPHICS_INVALID_COPYPROTECTION_TYPE comparison. remove the invalid type or select one reported for the output. During the ERROR_GRAPHICS_INVALID_COPYPROTECTION_TYPE comparison, keep every driver, monitor, resource format and unrelated policy unchanged.
3. Observe the layer after ERROR_GRAPHICS_INVALID_COPYPROTECTION_TYPE. For ERROR_GRAPHICS_INVALID_COPYPROTECTION_TYPE, if the exact check passes, record the next HRESULT or visible outcome. A different downstream result shows that the ERROR_GRAPHICS_INVALID_COPYPROTECTION_TYPE boundary was crossed.
4. Repeat ERROR_GRAPHICS_INVALID_COPYPROTECTION_TYPE through a lifecycle transition. For ERROR_GRAPHICS_INVALID_COPYPROTECTION_TYPE, exercise one relevant resize, mode switch, device recreation, hot-plug or session change and confirm that this result does not reuse stale handles.

The comparison with ERROR_GRAPHICS_OPM_NOT_SUPPORTED is especially useful: ERROR_GRAPHICS_OPM_NOT_SUPPORTED indicates the output protection subsystem is unavailable. For ERROR_GRAPHICS_INVALID_COPYPROTECTION_TYPE, recording both names prevents a broad “graphics error” label from merging distinct ownership, capability and lifetime problems.

Recovery contract

Negotiate output protection through OPM and keep VidPN metadata within documented enums. Repair of ERROR_GRAPHICS_INVALID_COPYPROTECTION_TYPE is complete only when the original call succeeds or returns its documented nonfatal status and the same lifetime test remains correct after a second display transition.

• The ERROR_GRAPHICS_INVALID_COPYPROTECTION_TYPE trace identifies one producing API and one current graphics object, rather than only the final UI symptom.
• The passing run changes exactly the condition described for ERROR_GRAPHICS_INVALID_COPYPROTECTION_TYPE; unrelated adapter, monitor and application state remains unchanged.
• For ERROR_GRAPHICS_INVALID_COPYPROTECTION_TYPE, debug-layer, ETW or driver diagnostics no longer report the rejected VidPN path copy-protection selection contract during the same scenario.
• The application handles recurrence of ERROR_GRAPHICS_INVALID_COPYPROTECTION_TYPE without an unbounded retry loop, leaked resource, duplicate composition target or stale topology handle.

Implementation notes for ERROR_GRAPHICS_INVALID_COPYPROTECTION_TYPE

For ERROR_GRAPHICS_INVALID_COPYPROTECTION_TYPE, log source and target IDs, topology generation, path descriptors, pinned modes, mode-set handles and monitor timing data. When the ERROR_GRAPHICS_INVALID_COPYPROTECTION_TYPE path returns a count, size, status flag or replacement object, retain it even on a nonfatal result because it can direct the next call.

A production fallback for ERROR_GRAPHICS_INVALID_COPYPROTECTION_TYPE should be explicit: pause rendering, re-enumerate, rebuild one cache entry, recreate a device, or decline a protected path only when this layer calls for that action. Reinstalling every display component, deleting all caches or forcing a resolution change is not an evidence-based fix for ERROR_GRAPHICS_INVALID_COPYPROTECTION_TYPE.
