ERROR_GRAPHICS_MCA_INTERNAL_ERROR
Why this is not a generic GPU failure: graphics mca internal error
ERROR_GRAPHICS_MCA_INTERNAL_ERROR (0xC0262588) belongs to the monitor layer. It marks the MCA/DDC-CI layer failed internally while communicating with or interpreting the physical monitor, rather than a generic rendering failure. The object that owns the decision is Monitor Configuration API transaction.
The smallest evidence set
| Capture item | Why it matters |
|---|---|
| What to capture | physical-monitor handle, HMONITOR, VCP operation, monitor description, transport error and display-change events |
| Current graph state | HMONITOR-to-physical-monitor enumeration and DDC/CI transaction |
| Supporting trace | physical-monitor handle generation, monitor description, VCP feature, DDC/CI exchange and display-change timestamp |
| Object identity | Monitor Configuration API transaction |
| Rejected condition | the MCA/DDC-CI layer failed internally while communicating with or interpreting the physical monitor |
A/B test for the exact condition
- Reacquire the physical monitor handle and issue a read-only capability query.
The comparison with ERROR_GRAPHICS_DDCCI_INVALID_DATA is especially useful: ERROR_GRAPHICS_DDCCI_INVALID_DATA identifies malformed monitor protocol data more specifically.
Safe remediation
Re-enumerate the monitor and separate transport failure from unsupported VCP features.
- debug-layer, ETW or driver diagnostics no longer report the rejected Monitor Configuration API transaction contract during the same scenario.
