DisplayConfigVideoSignalInfoVerticalSyncFreqDivider Field

The ratio of the VSync rate of a monitor that displays through a Miracast connected session to the VSync rate of the Miracast sink.

To avoid visual artifacts, the VSync rate of the display monitor that's connected to the Miracast sink must be an integer multiple of the VSync rate of the Miracast sink.

The display miniport driver reports the latter rate to the operating system as the refresh rate of the desktop present path.

The operating system fails any attempt by the driver to add a target mode that results in a Miracast target having a VSync rate below 23.9 Hz.

For a non-Miracast target, the driver should set VerticalSyncFreqDivider to zero.

Supported starting with Windows 8.1.
