ERROR_GRAPHICS_INVALID_COLORBASIS
Why this is not a generic GPU failure: graphics invalid colorbasis
ERROR_GRAPHICS_INVALID_COLORBASIS, value 0xC026233E, is produced by vidpn when the mode or path uses an unrecognized or incompatible color-space basis. The investigation should stay attached to VidPN color basis and to the exact generation in which it was obtained.
The smallest evidence set
| Capture item | Why it matters |
|---|---|
| Object identity | VidPN color basis |
| Rejected condition | the mode or path uses an unrecognized or incompatible color-space basis |
| What to capture | color-basis enum, pixel format, target signal mode, HDR/colorimetry state and driver support |
| Current graph state | VidPN, topology, source and target mode sets, and the present path connecting them |
| Supporting trace | source and target IDs, topology generation, path descriptors, pinned modes, mode-set handles and monitor timing data |
A/B test for the exact condition
- Replace only the color basis with one enumerated for the same format and target.
The comparison with ERROR_GRAPHICS_INVALID_PIXELFORMAT is especially useful: ERROR_GRAPHICS_INVALID_PIXELFORMAT is about storage representation rather than color-space semantics.
Safe remediation
Choose color basis from the cofunctional modality rather than copying it across outputs.
- debug-layer, ETW or driver diagnostics no longer report the rejected VidPN color basis contract during the same scenario.
