ERROR_GRAPHICS_VIDPN_MODALITY_NOT_SUPPORTED

ERROR_GRAPHICS_VIDPN_MODALITY_NOT_SUPPORTED (0xC0262306) means the requested VidPN modality is not supported. The chosen pinned source and target modes cannot operate together as one functional display configuration.

What to check

  • Check the complete source, target, refresh-rate, and resolution combination rather than validating each mode in isolation.
  • For driver development, enumerate cofunctional modes and keep pinned modes compatible with all affected paths.
  • For end users, simplify the display arrangement or choose modes known to be supported by all displays in a clone configuration.

Useful command

dxdiag /t "%USERPROFILE%\Desktop\dxdiag.txt"
