STATUS_GRAPHICS_INVALID_MONITOR_SOURCEMODESET
The mode-set container is invalid, not merely one mode
STATUS_GRAPHICS_INVALID_MONITOR_SOURCEMODESET applies to the VidPN object that contains monitor source modes for a target. A monitor source mode set is separate from the adapter source mode set and target mode set; it represents signal formats supported by the external display connected to that target.
Diagnose object provenance and lifetime first. A set can be stale after a topology change, associated with the wrong target, or obtained from an incompatible operation. Reusing a handle or structure from an earlier VidPN can produce this status even when the individual modes would otherwise be valid.
What to check
- Log the VidPN handle, target ID, current topology generation, acquisition call, and release point.
- Acquire a fresh monitor source mode set for the current target rather than editing a retained one.
- Separate an invalid set from an invalid mode within a valid set and from an empty intersection with adapter capabilities.
