Get Screen resolution using WMI/powershell in Windows 7

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


BitsPerPixel : 32
Bounds       : {X=0,Y=0,Width=1280,Height=800}
DeviceName   : \\.\DISPLAY1
Primary      : True
WorkingArea  : {X=0,Y=0,Width=1280,Height=770}

BitsPerPixel : 32
Bounds       : {X=1280,Y=0,Width=1920,Height=1200}
DeviceName   : \\.\DISPLAY2
Primary      : False
WorkingArea  : {X=1280,Y=0,Width=1920,Height=1170}

You can grab this from the Win32_VideoController WMI class. The VideoModeDescription property includes the screen resolution and the color depth.

(Get-WmiObject -Class Win32_VideoController).VideoModeDescription;
