How to identify actual used display with Powershell

Question

Hi,

I have a PowerShell script with a GUI in a multi monitor environment. When moving the GUI Window from one screen to another, is there any possibility to check on which screen the window is (in order to reset the resolution of the GUI Window according to screen resolution/size). I have identified all screens with their resolution, but I cannot identify on which screen the window is programmatically...

Cheers, Linus

Hello Linus,

Thank you for your question and for reaching out with your question today.

I have used the following code in the past to identify the monitors within my multi monitor setup:

function GetMonitorSerial () {
        $Monitor =(Get-WmiObject -NameSpace root\wmi -Class wmiMonitorID -EA 0 | ForEach-Object {
            $([System.Text.Encoding]::Ascii.GetString($($_.SerialNumberID)))
        })

        $MON0 = $Monitor[0]
        $MON1 = $Monitor[1]
    $MON2 = $Monitor[2]
    $MON3 = $Monitor[3]
        Write-Host "Monitor #0: " $MON0
        Write-Host "Monitor #1: " $MON1
    Write-Host "Monitor #2: " $MON2
    Write-Host "Monitor #3: " $MON3
    }

    GetMonitorSerial
