MultiMonitorTool is a small tool that allows you to do some actions related to working with multiple monitors. With MultiMonitorTool, you can disable/enable monitors, set the primary monitor, save and load the configuration of all monitors, and move windows from one monitor to another. You can do these actions from the user interface or from command-line, without displaying user interface. MultiMonitorTool also provides a preview window, which allows you to watch a preview of every monitor on your system.

System Requirements and Limitations

  • This utility works on any version of Windows, starting from Windows XP and up to Windows 10. Both 32-bit and x64 systems are supported.
  • This utility is only useful if your desktop is extended to multiple monitors. If you have multiple monitors that display the same content, then MultiMonitorTool is useless for you.

Versions History

  • Version 1.85
    • When making changes from command-line ( /enable, /disable, and so on...) MultiMonitorTool now loads all monitors to the internal list that is used to delect the specified monitor, including monitors detected as 'Duplicate' and 'Disconnected'. In previous versions, MultiMonitorTool failed to find the monitor if it was detected as Duplicate/Disconnected.
    • Made a small change that hopefully will fix incorrect MonitorID problem on some systems.
    • When duplicate monitors are detected and 'Show Duplicate Monitors' is turned off, MultiMonitorTool now takes the first monitor item instead of the second one.
    • Added 'Disconnected' column.
  • Version 1.83
    • Added 'Show Duplicate Monitors' option. On version 1.80, a bug that caused MultiMonitorTool to display the same monitor more than once was fixed, but it seems that on some systems, this bug fix may cause MultiMonitorTool to ignore a second monitor. So if you don't see all monitors on your system, you should try to turn on the 'Show Duplicate Monitors' option...
  • Version 1.82
    • You can now specify the Monitor ID value in all command-line options (/disable, /enable, /switch, and so on), for example:
      MultiMonitorTool.exe /enable "MONITOR\GSM59A4\{4d36e96e-e325-11ce-bfc1-08002be10318}\0012"
  • Version 1.81
    • Added 'Show Disconnected Monitors' option.
  • Version 1.80
    • Fixed bug: In some monitor configurations, MultiMonitorTool displayed the same monitor more than once.
    • The monitor ID of every monitor is now saved into the monitors configuration file.
    • Added 'Use Monitor ID In Load Config' option, If you turn it on, MultiMonitorTool will use the monitor ID to detect the correct monitors when you load a monitors configuration file.
  • Version 1.75
    • Added new columns: Monitor ID, Monitor Key, Monitor String, Monitor Name, Monitor Serial Number. (The values of 'Monitor Name' and 'Monitor Serial Number' columns are taken from the EDID data of the monitor)
    • Fixed bug: The Left-Top column displayed the coodinates as top-left instead of left-top.
  • Version 1.72
    • Fixed bug: MultiMonitorTool failed to remember the last size/position of the main window and the monitor preview window if they were not located in the primary monitor.
  • Version 1.71:
    • Fixed MultiMonitorTool to avoid from moving to another monitor the secondary taskbar (Shell_SecondaryTrayWnd class) of Windows 8.
  • Version 1.70:
    • Added option to set the update rate of the monitor preview window (the default rate is 1000 milliseconds) in the Advanced Options window (Ctrl+O).

    • Added 'Always On Top' option for the preview window.
  • Version 1.63:

Using MultiMonitorTool

MultiMonitorTool doesn't require any installation process or additional dll files. In order to start using it, simply run the executable file - MultiMonitorTool.exe

The main window of MultiMonitorTool contains 2 panes: The upper pane displays the list of all monitors detected on your system. When you select a monitor in the upper pane, the lower pane displays the details of all visible windows on the selected monitor.

You can select one or more monitors in the upper pane, and then use the following options: Disable Selected Monitors (Ctrl+F6), Enable Selected Monitors (Ctrl+F7), Disable/Enable Switch (Ctrl+F8), or Set As Primary Monitor (Ctrl+F9)
You can also select one or more Windows in the lower pane, and then use the 'Move Window To Next Monitor' and 'Move Window To Primary Monitor' options in order to easily move Windows from one monitor to the other.

Save/Load Monitors Configuration

MultiMonitorTool allows you to save the current configuration of all monitors on your system, including the screen resolution, colors depth, and monitor position of every monitor, by using the 'Save Monitors Configuration' option (Ctrl+Shift+S).
You can restore back the saved monitors configuration by using the 'Load Monitors Configuration' option (Ctrl+Shift+L).
You can also save/load the monitors configuration from command-line, by using the /SaveConfig and /LoadConfig command-line options.

Preview Window

The preview window shows you a preview of the monitor you select in the upper pane. It might be useful if non-primary monitors are turned off and you want to view the windows displayed in the other monitors. In order to enable/disable the monitor preview window, simply press F2. You can also resize the preview window to any size you like.

Command-Line Options

You can use the following command-line options to change the monitor configuration or to move windows automatically without displaying any user interface.
The <Monitor> parameter in all command-line options may contain the following values:
  • Primary - Specifies that you want to do the action on the primary monitor.
  • Monitor Name, as it appears in the 'Name' column, for example: \\.\DISPLAY1 , \\.\DISPLAY2, \\.\DISPLAY3
  • Monitor Number - The number that appears in the monitor name. (1 for \\.\DISPLAY1, 2 for \\.\DISPLAY2, and so on...)
  • Monitor ID, as it appears in the 'Monitor ID' column, for example: MONITOR\GSM59A4\{4d36e96e-e325-11ce-bfc1-08002be10318}\0008

/disable <Monitors> Disables the specified monitors. You can specify a single monitor or multiple monitors.
MultiMonitorTool.exe /disable 1
MultiMonitorTool.exe /disable \\.\DISPLAY3
MultiMonitorTool.exe /disable 1 2 3

MultiMonitorTool.exe /enable 3
MultiMonitorTool.exe /enable \\.\DISPLAY1
MultiMonitorTool.exe /enable 3 2
/switch <Monitors> Switches the specified monitors between enabled and disabled state.
MultiMonitorTool.exe /switch 3
MultiMonitorTool.exe /switch \\.\DISPLAY1
MultiMonitorTool.exe /switch \\.\DISPLAY2 \\.\DISPLAY3
/setmax <Monitors> Set the maximum resolution on the specified monitors.
MultiMonitorTool.exe /setmax 3
MultiMonitorTool.exe /setmax \\.\DISPLAY2 \\.\DISPLAY3

/SetPrimary <Monitor> Set the primary monitor.
MultiMonitorTool.exe /SetPrimary 2
MultiMonitorTool.exe /SetPrimary \\.\DISPLAY2
/SetNextPrimary Set the next available monitor as the primary monitor. For example, if you have a system with 3 monitors and the first monitor is the primary, running this command will set the second monitor as the primary. running this command again will set the third monitor as the primary. And... running this command again will set (again) the first monitor as the primary.
/PreviewOnly <Monitor> {x} {y} {width} {height} Allows you to run MultiMonitorTool in monitor preview only mode. In this mode, only the monitor preview window is displayed.
You must specify the monitor name to display in the preview window. Optionally, you can also specify the position and size to set the preview window.

MultiMonitorTool.exe /PreviewOnly \\.\DISPLAY1 10 10 300 200
/SaveConfig <Filename> Saves the current configuration of all your monitors into the specified filename, including the screen resolution, colors depth, and monitor position.
You can load the saved configuration back into the system by using the /LoadConfig command-line option.
MultiMonitorTool.exe /SaveConfig "c:\temp\monitors1.cfg"
/LoadConfig <Filename> Loads the monitors configuration that you previouly saved with /SaveConfig
MultiMonitorTool.exe /LoadConfig "c:\temp\monitors1.cfg"

/MoveWindow <To Monitor> Process <Process Name>
/MoveWindow <To Monitor> Title <Title Text>
/MoveWindow <To Monitor> Class <Window Class>
