DXGI_DDI_ERR_UNSUPPORTED

Interpret the result in its owning layer: ddi err unsupported

The useful interpretation of DXGI_DDI_ERR_UNSUPPORTED (0x887B0002) starts at the dxgi error boundary: the driver rejected a requested resource description or operation it does not implement. In practical terms, inspect user-mode display driver resource contract before changing application-wide graphics settings.

Capture before recreating objects

Capture itemWhy it matters
Supporting traceDXGI debug messages, adapter LUID, driver version, device-removal reason where applicable and the exact API parameters
Object identityuser-mode display driver resource contract
Rejected conditionthe driver rejected a requested resource description or operation it does not implement
What to captureresource dimension, format, bind and misc flags, feature level, format-support queries and DDI version
Current graph stateDXGI factory, adapter, device, resource or cache session

Reproduce one variable at a time

  1. Capture the failing state. Record resource dimension, format, bind and misc flags, feature level, format-support queries and DDI version.
  2. Reduce the resource description to a documented supported combination and reintroduce one flag at a time.

The comparison with DXGI_ERROR_UNSUPPORTED is especially useful: DXGI_ERROR_UNSUPPORTED is the public runtime result and can also cover broader platform limitations.

Recovery contract

Gate creation on capability queries and provide a compatible fallback format or usage.

  • debug-layer, ETW or driver diagnostics no longer report the rejected user-mode display driver resource contract during the same scenario.
