To enumerate the screens that intersect a clipping region, call the EnumDisplayMonitorsfunction. This function returns the HMONITORhandle for each screen, which you can use when calling the GetMonitorInfofunction.

To enumerate all the screens covered by the virtual screen, call EnumDisplayMonitorswith the hdcand lprcClipparameters set to NULL. The following code example shows how to enumerate all the screens covered by the virtual screen.

Copy Code 
EnumDisplayMonitors(NULL, NULL, MyInfoEnumProc, 0);
