I am using the following script to get screen resolution in Windows using WMI. The script works fine when the computer is in landscape mode but returns incorrect values when in portrait mode. Works properly in XP and did not try in Vista. Can anyone confirm this is bug in Windows 7 WMI.
strComputer = "."
Set objWMIService = GetObject("winmgmts:\\" & strComputer & "\root\CIMV2")
Set colItems = objWMIService.ExecQuery( _
"SELECT * FROM Win32_DesktopMonitor",,48)
For Each objItem in colItems
Wscript.Echo "-----------------------------------"
Wscript.Echo "Win32_DesktopMonitor instance"
Wscript.Echo "-----------------------------------"
Wscript.Echo "ScreenHeight: " & objItem.ScreenHeight
Wscript.Echo "ScreenWidth: " & objItem.ScreenWidth
Next
For the record, the PowerShell code is:
Get-WmiObject -Class Win32_DesktopMonitor | Select-Object ScreenWidth,ScreenHeight
I get the same values in Landscape or in Portrait mode.
UPDATE:
In a multi monitor environment you can get the info for all monitors with:
PS> Add-Type -AssemblyName System.Windows.Forms
PS> [System.Windows.Forms.Screen]::AllScreens
