ERROR_GRAPHICS_OPM_DRIVER_INTERNAL_ERROR
Why this is not a generic GPU failure: graphics opm driver internal error
Windows reports ERROR_GRAPHICS_OPM_DRIVER_INTERNAL_ERROR (0xC026251E) at the opm checkpoint. Here, the signed OPM request reached the driver and the driver reported an unexpected internal failure. That narrows the first investigation to display-miniport OPM implementation instead of the entire GPU stack.
Output protection is a policy-enforcement path. A fallback must respect the content policy; disabling HDCP or ignoring a signed-request failure is not a valid repair.
The smallest evidence set
| Capture item | Why it matters |
|---|---|
| Rejected condition | the signed OPM request reached the driver and the driver reported an unexpected internal failure |
| What to capture | adapter/driver version, output connector, OPM command, sequence number, protection level and kernel diagnostics |
| Current graph state | OPM protected-output session, signed request and display-miniport response |
| Supporting trace | output certificate, OPM semantics, sequence number, command GUID, protection level and connector status |
| Object identity | display-miniport OPM implementation |
A/B test for the exact condition
- Capture the failing state. Record adapter/driver version, output connector, OPM command, sequence number, protection level and kernel diagnostics.
- Repeat the same request on another output or driver version without changing the signed request fields.
The comparison with ERROR_GRAPHICS_OPM_INTERNAL_ERROR is especially useful: ERROR_GRAPHICS_OPM_INTERNAL_ERROR does not specifically attribute the fault to the driver.
Safe remediation
Update or correct the display driver and fall back according to content policy; do not bypass required output protection.
- debug-layer, ETW or driver diagnostics no longer report the rejected display-miniport OPM implementation contract during the same scenario.
