Powershell：如何获取登录用户的主屏幕分辨率？

I am looking for an easy to implement or more elegant solution to the ugly one i mentioned.

Our current scenario is this:

We have more than 80 tablet computers (running Windows 10) in our network that run under the same user ( DefaultUser ). In order to verify that the display settings are correctly set, we would like to use a powershell script to automatically check the used resolution remotely with a support user account.

So far, we know how to get the primary screen resolution for the user under which the script gets executed (which is rather easy):

  // get primary screen width
  Add-Type -AssemblyName System.Windows.Forms
  [System.Windows.Forms.Screen]::PrimaryScreen.Bounds.Width   // height accordingly

In case we execute this script on one of the tablets using the support account, we get the primary screen resolution for the support account user - but not for the desired user DefaultUser .

How can we get the resolution for the DefaultUser ?

The only solution that easily comes to my mind is a rather ugly thing: Using the windows task scheduler i could create a task that executes the script (under the defaultUser) to get the screen resolution and write the result(s) into a file that can be accessed by the support user account. But i am looking for something more elegant.

Answer 1

You may be able to use CIM or WMI to get from point a to b.

CIM_VideoController is the class that would contain the resolution.

Using PowerShell Core:

Get-CimInstance CIM_VideoController | Select SystemName, CurrentHorizontalResolution, CurrentVerticalResolution

Using Windows PowerShell:

Get-WmiObject Win32_VideoController | Select SystemName, CurrentHorizontalResolution, CurrentVerticalResolution

You should be able to open the proper ports to use either of these options remotely (though you could also probably get away with using Invoke-Command to run them, as long as you use CredSSP or Kerberos Delegation to take the 2nd hop problem into account).
