Delete content from variable in Powershell

Question

My problem is, how can I delete some content from a variable? I just want to get the coordinates of my screens.

So I can get the content with $screen1 = Get-WmiObject win32_desktopmonitor but I don't know how to get rid of the rest of the content I don't need.

Here is the output:

DeviceID            : DesktopMonitor1
DisplayType         : 
MonitorManufacturer : 
Name                : Standardmonitor
ScreenHeight        : 
ScreenWidth         : 

DeviceID            : DesktopMonitor2
DisplayType         : 
MonitorManufacturer : 
Name                : Standardmonitor
ScreenHeight        : 1200
ScreenWidth         : 1920

DeviceID            : DesktopMonitor3
DisplayType         : 
MonitorManufacturer : (Standardmonitortypen)
Name                : PnP-Monitor (Standard)
ScreenHeight        : 1200
ScreenWidth         : 1920

I just need the screen height and width of DesktopMonitor2 and the other one I would save in a new variable.

I need this to open two browser screens in kiosk mode on different screens. Can anybody help me?

I didn't notice that you're using an old version of Windows PowerShell.
_{(I recommend you to update to the latest version of Windows PowersShell 5.1 or even better: PowerShell Core usingGet-CimInstance)}

Anyways, for PowerShell 3.0, you should be able to do this:

$Screens = Get-WmiObject win32_desktopmonitor
$Screen2 = $Screens | Where-Object { $_.DeviceID -eq DesktopMonitor2 }
$Width2 = $Screen2.ScreenWidth
$Height2 = $Screen2.ScreenHeight
