How to build WDDM driver vidpn RRS feed

  • Question

  • I am writing WDDM filter driver for creating virtual displays.

    I support the virtual child device and video source associated paths in the DxgkDdiIsSupportedVidPn function, such as Paths(source->target):(0 <-> 0), (1 <-> 4),

    DxgkDdiEnumVidPnCofuncModality function specifies the target ID = 4, other target IDs are omitted, in Here I add source mode and target mode to this ID=4 path.

    I can see multiple monitors in Desktop Properties → Resolution, but I can't modify the resolution of the monitor and extend the desktop, this monitor Can't save display settings error?
