ERROR_GRAPHICS_INCONSISTENT_DEVICE_LINK_STATE
Why this is not a generic GPU failure: graphics inconsistent device link state
ERROR_GRAPHICS_INCONSISTENT_DEVICE_LINK_STATE, value 0xC0262436, is produced by linked when members of the linked set are in incompatible PnP or power states. The investigation should stay attached to linked-adapter PnP/power consistency and to the exact generation in which it was obtained.
This result: Linked-adapter failures are ordered PnP and power problems. Restarting only the lead member can make the state less consistent and hide the first failing chain device. 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.
The smallest evidence set
| Capture item | Why it matters for it |
|---|---|
| Rejected boundary | members of the linked set are in incompatible PnP or power states |
| Decisive capture | member-by-member PnP and Dx states, transition history, surprise-removal and driver versions |
| Current graph state | lead adapter, chain members and their PnP/power transitions |
| Supporting trace | device-instance IDs, lead/chain role, PnP problem codes, Dx states and start/power IRP ordering |
| Object identity | linked-adapter PnP/power consistency |
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 this result.
A/B test for the exact condition
- Freeze the result generation. Record member-by-member PnP and Dx states, transition history, surprise-removal and driver versions. Before diagnosing this result, do not resize, hot-plug, recreate or release the object under examination.
- Run the narrow this result comparison. bring all members to one known state and repeat the operation. During the result comparison, keep every driver, monitor, resource format and unrelated policy unchanged.
- Observe the layer after it. for it, if the exact check passes, record the next HRESULT or visible outcome. A different downstream result shows that the boundary was crossed.
- Repeat it through a lifecycle transition. for it, exercise one relevant resize, mode switch, device recreation, hot-plug or session change and confirm that it does not reuse stale handles.
The comparison with ERROR_GRAPHICS_ADAPTER_CHAIN_NOT_READY is especially useful: ERROR_GRAPHICS_ADAPTER_CHAIN_NOT_READY is an aggregate readiness result without the explicit state mismatch. Recording both names prevents a broad “graphics error” label from merging distinct ownership, capability and lifetime problems.
Safe remediation
Repair transition synchronization and tear down the chain on member removal. Repair of it 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 result 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 it; unrelated adapter, monitor and application state remains unchanged.
- debug-layer, ETW or driver diagnostics no longer report the rejected linked-adapter PnP/power consistency contract during the same scenario.
- The application handles recurrence of it without an unbounded retry loop, leaked resource, duplicate composition target or stale topology handle.
Implementation notes
Log device-instance IDs, lead/chain role, PnP problem codes, Dx states and start/power IRP ordering. When the 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 it 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 it.
