What's inside ClickMonitorDDC

  1. Overview of ClickMonitorDDC 7.2

    master

    ClickMonitorDDC is a Windows utility (compatible with Windows 7, 8, and 10) used to adjust monitor brightness, contrast, and other hardware settings via the DDC/CI protocol or laptop LCD controls.

    Key features include:

    • Taskbar Control: Adjust values using notification icons or the mouse wheel over them.
    • Command Line Interface: Create powerful automation via batch files, popup menus, or shortcuts.
    • Automation: Execute commands at specific times, via hotkeys, or automatically when certain programs enter fullscreen.
    • Multi-Monitor Support: Target specific monitors using names, models, serial numbers, or numbers.

  2. Advanced VCP control (Use with caution)

    master

    ClickMonitorDDC provides access to VCP-codes defined by MCCS (VESA Monitor Control Command Set). While the software provides high-level arguments for common tasks, you can use setVCP and getVCP for direct hardware control.

    Warning: Using setVCP or getVCP can potentially harm your monitor in rare cases. It is recommended to use the standard arguments (like b, c, etc.) instead.

    • getVCP <vcp_code>: Shows actual and maximum value in a messagebox.
    • get_VCP <vcp_code>: Returns the current VCP code value as the system errorlevel.
    • setVCP <vcp_code> <value>: Sets the monitor to a specific value.
    • setVCP <vcp_code> <+/-><value>: Adjusts the current value by the specified amount.

    Example:

    • setVCP 0x10 50 is equivalent to b 50.
    • setVCP 0x10 + 10 is equivalent to b + 10.
    getVCP 0x12
get_VCP 0x12
setVCP 0x10 50
setVCP 0x10 + 10

  3. Target a specific monitor in command lines

    master

    When working with multiple monitors, you can prepend a monitor identifier to your command to ensure the arguments apply to the correct display. You can use:

    • monitorname
    • modelname
    • serialnumber
    • monitornumber (Note: position-based numbering is not recommended as Windows may change positions).
    • A self-defined monitor name.

    Important: When using monitorname, modelname, or serialnumber, omit spaces (e.g., use HPw2207 instead of HP w2207) or wrap the name in quotes (e.g., "HP w2207").

    Example: PL2779Q b 36 sets brightness to 36 for the monitor named PL2779Q.

    PL2779Q b 36 HPA34T c - 5

  4. Configure auto-run command lines by time

    master

    You can define up to 8 specific times in the Settings (Timer, Transfer, Limits) section to automatically execute command lines.

    • Commands are executed one-time per day when the time condition is met.
    • If you boot your computer after a scheduled time has passed, ClickMonitorDDC will execute the nearest past time-command once.
    • To force a command to run again, restart ClickMonitorDDC or enter/leave the settings window.

    Example schedule:

    07:00 AM b 30
08:00 AM b 40
09:00 AM b 50
07:30 PM b 40
08:20 PM b 30
08:40 PM b 20

  5. Use the toggle feature for profiles

    master

    The t argument allows you to toggle between two different monitor states using a single command or hotkey. This is useful for switching between a 'work' profile and a 'gaming' or 'movie' profile.

    Example: t b 0 c 0 t b 100 c 100

    • First execution: Sets brightness 0, contrast 0.
    • Second execution: Sets brightness 100, contrast 100.
    • Third execution: Returns to the first state.
    t b 0 c 0 t b 100 c 100

  6. Reference: ClickMonitorDDC command-line arguments

    master

    Use the following arguments to control monitor hardware and system settings via the CLI.
