For Roger's WMI provider, you're going to want the ,key field defined. I checked, and it is pnpid. replace your sms_def.mof edit with this one:
[ SMS_Report (TRUE),
SMS_Group_Name ("MonitorDetails"),
SMS_Class_ID ("RogerZander|DisplayMonitorDetails|1.0") ]
class Win32_MonitorDetails : SMS_Class_Template
{
[SMS_Report (True), key ] string PnPID;
[SMS_Report (True) ] string SerialNumber;
[SMS_Report (True) ] string Model;
[SMS_Report (True) ] string MonitorID;
};
I am, of course, assuming that you've confirmed the pre-requisite of the minimum .net Framework version, and you've installed Roger Zanders' WMI Monitor Details .exe on your clients.
