None
The miniport driver returns an array of VIDEO_MODE_INFORMATION structures in the VRP OutputBuffer.
If the miniport driver successfully returns the available modes, it sets the Information member of the STATUS_BLOCK structure to (sizeof(VIDEO_MODE_INFORMATION) * NumberOfSupportedModes); otherwise, the miniport driver sets this member to zero.
