ERROR_GRAPHICS_NO_VIDPNMGR
What Windows rejected: graphics no vidpnmgr
The useful interpretation of ERROR_GRAPHICS_NO_VIDPNMGR (0xC0262335) starts at the vidpn boundary: the selected adapter does not expose a VidPN manager for the requested operation. In practical terms, inspect adapter display-mode manager availability before changing application-wide graphics settings.
Diagnostic discriminator: Microsoft describes this condition as “Display adapter in question does not have an associated VidPN manager.” Use that exact state to separate the value from nearby results in the same subsystem.
Build a useful diagnostic record
| Capture item | Why it matters |
|---|---|
| Rejected condition | the selected adapter does not expose a VidPN manager for the requested operation |
| What to capture | adapter LUID, driver model, render-only flag, output enumeration and DMM interface acquisition result |
| 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 |
| Object identity | adapter display-mode manager availability |
Separate state from capability
- Capture the failing state. Record adapter LUID, driver model, render-only flag, output enumeration and DMM interface acquisition result.
- Repeat against a display-capable adapter and a render-only adapter.
The comparison with ERROR_GRAPHICS_NO_ACTIVE_VIDPN is especially useful: ERROR_GRAPHICS_NO_ACTIVE_VIDPN means a manager exists but has no active topology.
Verify the repaired path
Select an adapter with display outputs or avoid mode-management calls on render-only devices.
- debug-layer, ETW or driver diagnostics no longer report the rejected adapter display-mode manager availability contract during the same scenario.
