ERROR_GRAPHICS_NO_DISPLAY_MODE_MANAGEMENT_SUPPORT

What Windows rejected: graphics no display mode management support

The useful interpretation of ERROR_GRAPHICS_NO_DISPLAY_MODE_MANAGEMENT_SUPPORT (0xC0262341) starts at the vidpn boundary: the adapter or driver path cannot provide the interface required to manipulate VidPN modes. In practical terms, inspect display mode management interface before changing application-wide graphics settings.

Diagnostic discriminator: Microsoft describes this condition as “Failed to acquire display mode management interface.” Use that exact state to separate the value from nearby results in the same subsystem.

What to captureadapter type, WDDM version, output count, DMM acquisition call and driver feature support

Separate state from capability

  1. Capture the failing state. Record adapter type, WDDM version, output count, DMM acquisition call and driver feature support.
  2. Compare the operation on a display-capable WDDM adapter and a render-only or unsupported adapter.

The comparison with ERROR_GRAPHICS_NO_VIDPNMGR is especially useful: ERROR_GRAPHICS_NO_VIDPNMGR means the associated manager object is absent.

Verify the repaired path

Gate mode-management code on adapter capability and use supported system configuration APIs.

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