Examples

The following PowerShell example retrieves the serial number of multiple monitors.


gwmi WmiMonitorID -Namespace root\wmi | ForEach-Object {($_.UserFriendlyName -notmatch 0 | foreach {[char]$_}) -join ""; ($_.SerialNumberID -notmatch 0 | foreach {[char]$_}) -join ""}


The following VBScript code also retrieves monitor ID information from a system.


Option Explicit

Dim strComputer, objWMIService, colItems, objItem

strComputer = "MyComputer"

Set objWMIService = GetObject("winmgmts:" _ 
  & "{impersonationLevel=impersonate,authenticationLevel=Pkt}!\\" _ 
  & strComputer & "\root\wmi") 

Set colItems = objWMIService.ExecQuery _
  ("SELECT * FROM WMIMonitorID")

For Each objItem In colItems
  Wscript.Echo objItem.InstanceName
Next
