I wanted to be able to obtain information on a monitor attached to a
Windows 10 desktop system, including the manufacturer,
model number, serial number, and date of manufacture, from a
command-line
interface (CLI). One way to do that is by using
PowerShell, which
Microsoft provides as part of its Windows operating system. You can open
a PowerShell window on a Microsoft Windows 10 system by typing
PowerShell in the "Type here to search" field at the bottom
of the Windows display. You should see the Windows PowerShell app listed as
an option you can click on to open a PowerShell window. If you type
gwmi WmiMonitorID -Namespace root\wmi at the prompt and hit
enter, you will see information similar to the following output displayed.
PS C:\> gwmi WmiMonitorID -Namespace root\wmi __GENUS : 2 __CLASS : WmiMonitorID __SUPERCLASS : MSMonitorClass __DYNASTY : MSMonitorClass __RELPATH : WmiMonitorID.InstanceName="DISPLAY\\HPN360C\\5&2c03a83e&0&UID262_0" __PROPERTY_COUNT : 9 __DERIVATION : {MSMonitorClass} __SERVER : YTTERBIUM __NAMESPACE : root\wmi __PATH : \\YTTERBIUM\root\wmi:WmiMonitorID.InstanceName="DISPLAY\\HPN360C\\5&2c03a83e&0&UID262_0" Active : True InstanceName : DISPLAY\HPN360C\5&2c03a83e&0&UID262_0 ManufacturerName : {72, 80, 78, 0...} ProductCodeID : {51, 54, 48, 67...} SerialNumberID : {67, 78, 75, 48...} UserFriendlyName : {72, 80, 32, 51...} UserFriendlyNameLength : 13 WeekOfManufacture : 12 YearOfManufacture : 2020 PSComputerName : YTTERBIUM PS C:\>
In the above output, you can see that the name of the manufacturer, product code id, serial number, etc. are displayed as a sequence of number, i.e., in a format that is not readily human-interpretable. The following PowerShell script, which is a modified version of one provided by Nicholas Bundy at Get monitor Manufacturer, Model, and serial number, will reformat that information to a format more readily understandable. You can save the code as a .ps1 script file or you can just copy and paste it into a PowerShell window and then hit Enter to see the output.
function Decode {
If ($args[0] -is [System.Array]) {
[System.Text.Encoding]::ASCII.GetString($args[0])
}
Else {
"Not Found"
}
}
ForEach ($Monitor in Get-WmiObject WmiMonitorID -Namespace root\wmi) {
$Manufacturer = Decode $Monitor.ManufacturerName -notmatch 0
$Name = Decode $Monitor.UserFriendlyName -notmatch 0
$Serial = Decode $Monitor.SerialNumberID -notmatch 0
$ManufactureWeek = (Get-WmiObject WmiMonitorID -Namespace root\wmi).WeekofManufacture
$ManufactureYear = (Get-WmiObject WmiMonitorID -Namespace root\wmi).YearOfManufacture
echo "Manufacturer: $Manufacturer`nName: $Name`nSerial Number: $Serial"
echo "Week of Manufacture: $ManufactureWeek"
echo "Year of Manufacture: $ManufactureYear"
}
In the above code, a
backtick
character followed by an "n" produces a new line in the output. You could
also put output on a new line by using additional echo commands.
Or if you prefer to have the output all on one line, you could replace
the instances of `n with a comma followed by a space.
If you paste the above code into a PowerShell window and then hit Enter, you should see results similar to those below.
PS C:\> function Decode { >> If ($args[0] -is [System.Array]) { >> [System.Text.Encoding]::ASCII.GetString($args[0]) >> } >> Else { >> "Not Found" >> } >> } PS C:\> PS C:\> ForEach ($Monitor in Get-WmiObject WmiMonitorID -Namespace root\wmi) { >> $Manufacturer = Decode $Monitor.ManufacturerName -notmatch 0 >> $Name = Decode $Monitor.UserFriendlyName -notmatch 0 >> $Serial = Decode $Monitor.SerialNumberID -notmatch 0 >> $ManufactureWeek = (Get-WmiObject WmiMonitorID -Namespace root\wmi).WeekofManufacture >> $ManufactureYear = (Get-WmiObject WmiMonitorID -Namespace root\wmi).YearOfManufacture >> >> echo "Manufacturer: $Manufacturer`nName: $Name`nSerial Number: $Serial" >> echo "Week of Manufacture: $ManufactureWeek" >> echo "Year of Manufacture: $ManufactureYear" >> } Manufacturer: HPN Name: HP 32 QHD Serial Number: CNK0121RH2 Week of Manufacture: 12 Year of Manufacture: 2020 PS C:\>
If you just want the week and year of manufacture of the monitor, you can use the commands shown below.
PS C:\> (Get-WmiObject WmiMonitorID -Namespace root\wmi).WeekofManufacture 12 PS C:\> (Get-WmiObject WmiMonitorID -Namespace root\wmi).YearofManufacture 2020 PS C:\>
The "12" in the output for week of manufacture indicates the monitor was manufactured in March of 2020, which matched the label on the bottom of the HP QHD 32" monitor on which the commands above were run.
