    turn monitor off


    How to turn monitor off imediatelly after pc boot up so it's not On for 20 minutes after pc boots up.
    I don't want to change power settings because for the rest of the time it should be like it is in settings it turns off after 20 minutes of inactivity.
    I tried nircmd and powsershell but it doesn't work with task scheduler at windows startup.

    Hi, how do you do that?

    Well, I tried a scheduled task
    turn monitor off-1.png

    and that worked on my laptop.

    As for a desktop- well, sorry, don't have one..

    Just a thought - might you need a delay?

    Hello Blisk,

    If you like, you could use the tutorial below to add a "Turn off display" context menu to make it easy to manually turn off the display on demand.

    Turn Off Display cascading context menu - Add in Windows

    Otherwise, you should be able to have the command run at startup either by using a shortcut or .bat file in your Startup folder or task created to run at startup or log in.

    Thank you for your suggestions.
    But the problem is when I run nircmd with user" system" it doesn't work. I can't do that with admin rights in task scheduler.
    I also tested with startup and didn't manage to work, I will check those links and try again.
    I also tested that on laptop.

    Make sure you test whatever you are trying independently of the task scheduler first.

    E.g. if it's a command line, try it at a command prompt.

    Then if ok, in the task scheduler, and try rt clicking the task, click run.

    In what way is your user 'system'?

    You do not have the authority to do things as "system". And you don't need it for this job anyway.
    You do not even need Admin rights.
    Just run this command as I do almost every day.
    Code:
    NirCmd.exe monitor off
    You will need to put in the full path to where you have stored NirCmd. My full command is
    Code:
    C:\Tools\External\NirSoft\NirCmd\x64\NirCmd.exe monitor off

    Using the Trigger logon instead of Startup can often be more successful.
    In this case I think either would do.

    Thank you Try3
    The point is that monitor is off until user start to use computer. I can do that only when computer starts option, after login than is no point to do thatturn monitor off-2021-03-25-14_37_57-window.png

    Try setting the task to run at logon and to run with the highest privileges.

    I tried all and nothing works. I really need this. Is there really no way to turn monitor off when computer start and show login page?

    I am not at all sure what you have tried.

    1 Did you try putting a shortcut in your startup folder containing the NirCmd I described in post #6?
    C:\ProgramData\Microsoft\Windows\Start Menu\Programs\Startup
    - And you should test that shortcut now [even though your are logged in to Windows 10] to make sure you have written the shortcut correctly.

    2 Did you try running that command from Task scheduler with these settings?
    - Trigger - Startup
    - General tab entries: your own username, Run whether user is logged on or not
    - Not using the System user
    - Not using Run with highest privileges
    - And you should test that task now [even though you are logged in to Windows 10] to make sure you have written the task correctly.
    - To test it - run Task scheduler, select the task then right-click & select Run.

    If neither of these work then I think you will not find a solution other than not turning the computer on until you need it. Why do you turn it on earlier than that?
