Switching the video input source of a monitor can often be a cumbersome process. This task typically requires manual interaction with the monitor's buttons or on-screen display menus. However, if you are looking for a command-line interface (CLI) solution in Windows to change the video source input without the need for third-party applications, you're in the right place.
Understanding the Problem
Many users need to switch between multiple input sources on their monitors for various reasons, such as connecting different devices or using virtual machines. While most users rely on the physical buttons on their monitors, being able to do this through the command line can simplify workflows, especially for advanced users and developers.
The challenge arises from the fact that Windows does not natively support monitor input switching through CLI commands. Here's the original statement of the problem:
"How to switch monitor video source input by CLI in Windows without third party apps?"
Exploring CLI Options in Windows
While Windows itself does not provide a built-in command to change the video input source of monitors, you can leverage the Windows Management Instrumentation (WMI) and PowerShell scripts to communicate with your hardware. However, this may require some configuration.
Example PowerShell Script
You can use the following PowerShell script as a starting point to check connected displays. Please note that changing input sources via CLI may not work on all monitors and configurations.
Get-WmiObject -Namespace root\wmi -Class WmiMonitorBasicDisplayParams
This command retrieves basic display parameters, such as the name and resolution of the monitors connected to your system. Unfortunately, this won't switch inputs, but it provides useful information about your setup.
Using DisplaySwitch.exe
Another built-in utility you can use is DisplaySwitch.exe. This utility allows you to control your display settings to some extent:
-
Duplicate: Displays the same desktop on all connected monitors.
DisplaySwitch.exe /clone -
Extend: Extends your desktop across all connected monitors.
DisplaySwitch.exe /extend -
Second Screen Only: Turns off the primary display and uses only the second screen.
DisplaySwitch.exe /external
These commands won't change the input source but may help in managing display outputs in some scenarios.
Limitations and Considerations
-
Manufacturer-Specific Solutions: Many monitors have manufacturer-specific software that allows for more direct control over inputs. Check your monitor's user manual for potential CLI options.
-
Administrative Rights: Some commands and scripts may require administrative rights to execute properly. Ensure that you run PowerShell or Command Prompt as an administrator when attempting to switch configurations.
-
Hardware Dependencies: Not all hardware configurations will support input switching via software due to how inputs are managed at the hardware level.
Conclusion
While Windows doesn't provide a direct command for switching monitor video source inputs through the command line, utilizing PowerShell and DisplaySwitch.exe can help manage connected displays to a certain extent. If you're looking for advanced management capabilities, exploring manufacturer-specific software or considering a more programmable solution might be necessary.
