IVMRMonitorConfig9 interface

The IVMRMonitorConfig9 interface is implemented by the Video Mixing Renderer Filter 9 (VMR-9). Applications use this interface to determine the capabilities of the display devices on the system and to control which device is used to display the output. For example, if the system contains a hardware DVD decoder and the VMR is rendering the output from that decoder, then on a multi-monitor system, an application must use this interface to specify the display device that is connected to the decoder.

The VMR-9 supports a maximum of 16 display devices.


The IVMRMonitorConfig9 interface has these methods.

Method Description
IVMRMonitorConfig9::GetAvailableMonitors The GetAvailableMonitors method retrieves information about the monitors currently available on the system.
IVMRMonitorConfig9::GetDefaultMonitor The GetDefaultMonitor method retrieves the default monitor that all future instances of the VMR will use for video playback.
IVMRMonitorConfig9::GetMonitor The GetMonitor method retrieves the monitor that this instance of the VMR is using for video playback.
IVMRMonitorConfig9::SetDefaultMonitor The SetDefaultMonitor method specifies the default monitor that all future instances of the VMR should use for video playback.
IVMRMonitorConfig9::SetMonitor On a multi-monitor system, the SetMonitor method specifies the monitor that the VMR should use when it creates the Direct3D device.
