Calling powershell function in batch script - powershell

Question

Hoping someone can point me in the right direction. Have a working remote PC info scanning tool that collects computer name, serial number and model. Been trying to get the monitor info added for so time and found this Powershell script and have been trying to get intergraded without success.
Powershell function;
$Monitors = Get-WmiObject WmiMonitorID -Namespace root\wmi
$LogFile = ".\MonInfo.csv"
function Decode {
If ($args[0] -is [System.Array]) {
[System.Text.Encoding]::ASCII.GetString($args[0])
}
Else {
"Not Found"
}
}
ForEach ($Monitor in $Monitors) {
$Manufacturer = Decode $Monitor.ManufacturerName -notmatch 0
$Name = Decode $Monitor.UserFriendlyName -notmatch 0
$Serial = Decode $Monitor.SerialNumberID -notmatch 0
echo $Manufacturer, $Name, $Serial" >> $LogFile
}
Here's the network scan batch script I been using. (Basic info scan via ping and get info from remoter systems via WMI)

I have also tried calling for the .ps1 yet the variables are always empty and the corp network requires Powershell scripts to have sign cert to run by them selves.

Long time ago I wrote the script to get monitor serial number from registry.
It takes only first monitor value. But you can change this script or convert to Powershell. Anyway you can see script logic: get EDID-number, then parse it.
#for /f %%i in ('#wmic path win32_desktopmonitor get pnpdeviceid ^|#find "DISPLAY"') do #set val="HKLM\SYSTEM\CurrentControlSet\Enum\%%i\Device Parameters"
#reg query %val% /v EDID>NUL
#if %errorlevel% GTR 0 #echo BAD EDID&EXIT
#for /f "skip=2 tokens=1,2,3*" %%a in ('#reg query %val% /v EDID') do #set edid=%%c
#set /A Y=%edid:~34,1%*16+%edid:~35,1%+1990
#echo.Manufactured: %Y%
#set id=%edid:000000FC00=#%
#for /f "tokens=1,2* delims=#" %%a in ("%id%") do #set id=%%b
#set id=%id:~0,22%
#setlocal enableextensions enabledelayedexpansion
#echo off
#for /L %%i in (0,2,20) do (
#set p=!id:~%%i,2!
#if !p!==0A #goto nxt
#set m=!m!0x!p!
)
#echo on
:nxt
#forfiles /p %windir%\system32 /m shell32.dll /c "cmd /c #echo.Model : !m!"
#endlocal
#set edid=%edid:000000FF00=#%
#for /f "tokens=1,2* delims=#" %%a in ("%edid%") do #set id=%%b
#set id=%id:~0,20%
#setlocal enableextensions enabledelayedexpansion
#for /L %%i in (0,2,18) do #set sn=!sn!0x!id:~%%i,2!
#forfiles /p %windir%\system32 /m shell32.dll /c "cmd /c #echo.S.N. : !sn!"
#endlocal
