How To Get Info Of All Monitors With Python On Windows?

I need a way to get the manufacturer name and the data string of all the connected monitors in Windows and with Python. My final goal is a function that returns this for example: [

Solution 1:

This can be done by executing PowerShell command from your python script. To discover multi-monitor configuration information on your computer you use powershell Get-WmiObject win32_desktopmonitor command. Command output looks like this:

__GENUS                     :2__CLASS                     :Win32_DesktopMonitor__SUPERCLASS                :CIM_DesktopMonitor__DYNASTY                   :CIM_ManagedSystemElement__RELPATH                   :Win32_DesktopMonitor.DeviceID="DesktopMonitor1"__PROPERTY_COUNT            :28__DERIVATION                : {CIM_DesktopMonitor, CIM_Display, CIM_UserDevice,
                               CIM_LogicalDevice...}
__SERVER                    :SQUALL__NAMESPACE                 :root\cimv2__PATH                      :\\SQUALL\root\cimv2:Win32_DesktopMonitor.DeviceID="DesktopMonitor1"Availability                :3Bandwidth                   :Caption                     :LGIPS237(Analog)ConfigManagerErrorCode      :0ConfigManagerUserConfig     :FalseCreationClassName           :Win32_DesktopMonitorDescription                 :LGIPS237(Analog)DeviceID                    :DesktopMonitor1DisplayType                 :ErrorCleared                :ErrorDescription            :InstallDate                 :IsLocked                    :LastErrorCode               :MonitorManufacturer         :LGMonitorType                 :LGIPS237(Analog)Name                        :LGIPS237(Analog)PixelsPerXLogicalInch       :96PixelsPerYLogicalInch       :96PNPDeviceID                 :DISPLAY\GSM587D\5&2494DFB6&0&UID1048848PowerManagementCapabilities :PowerManagementSupported    :ScreenHeight                :1080ScreenWidth                 :1920Status                      :OKStatusInfo                  :SystemCreationClassName     :Win32_ComputerSystemSystemName                  :SQUALL

We need to get section Name, so use regex. The final code is:

import subprocess
import re

proc = subprocess.Popen(['powershell', 'Get-WmiObject win32_desktopmonitor;'], stdout=subprocess.PIPE)
res = proc.communicate()
monitors = re.findall('(?s)\r\nName\s+:\s(.*?)\r\n', res[0].decode("utf-8"))
print(monitors)

The result is:

['LG IPS237(Analog)']
