ERROR_GRAPHICS_DEPENDABLE_CHILD_STATUS
Locate the failing graphics boundary: graphics dependable child status
ERROR_GRAPHICS_DEPENDABLE_CHILD_STATUS (0x4026243C) belongs to the graphics info layer. It marks the driver marked its child presence result as reliable for the current detection cycle, rather than a generic rendering failure. The object that owns the decision is authoritative display-child presence report.
Evidence that makes the result actionable
| Capture item | Why it matters |
|---|---|
| Rejected condition | the driver marked its child presence result as reliable for the current detection cycle |
| What to capture | child UID, detection mechanism, timestamp, connector state and whether the result came from interrupt or poll |
| Current graph state | WDDM kernel/miniport callback and the transient object state carried by that callback |
| Supporting trace | kernel graphics ETW, callback name, child or allocation identifiers, PnP state and the first returned NTSTATUS/HRESULT |
| Object identity | authoritative display-child presence report |
A controlled comparison
- Capture the failing state. Record child UID, detection mechanism, timestamp, connector state and whether the result came from interrupt or poll.
- Compare one detection cycle with stable connector evidence against a deliberately indeterminate cycle.
The comparison with ERROR_GRAPHICS_UNKNOWN_CHILD_STATUS is especially useful: ERROR_GRAPHICS_UNKNOWN_CHILD_STATUS says the current presence answer cannot be relied upon.
Correction and proof
Use the result to update topology while retaining normal hot-plug invalidation rules.
- debug-layer, ETW or driver diagnostics no longer report the rejected authoritative display-child presence report contract during the same scenario.
