Query all monitors on a computer?

Hi,

I'm trying to figure out how to determine how many and what size monitors are connected to a computer running remotely at home, preferably using PowerShell at this moment. Following a Hey Scripting Guys blog post I've hit upon two approaches using wim32, wim32_VideoController and Wim32_DesktopMonitor. These are nice but they don't list all monitors on a system. Almost all of my users have two monitors at home.

Here's the simple script I'm using:
Get-WmiObject -Class "win32_videocontroller" -Namespace "root\CIMV2" -ComputerName $CompName
Get-WmiObject -Class "win32_desktopmonitor" -ComputerName $CompName

I can deduce the size of the monitor from the screen height/width or horizontal/vertical resolution depending which win32 class I am running.

My problem is that it is only returning information on 1 of the 2 monitors.

Any thoughts on how to get it to return all of the monitors attached to the system? Or, is there a better way to get this information that I haven't seen yet?

Thanks in advance!

Hi，

This command will return all the monitors for you

 Get-CimInstance -Namespace root\wmi -ClassName WmiMonitorBasicDisplayParams
