    Tool to control display brightness by command line?

    The control panel has a nice slider bar for controlling the screen/display brightness, but I have a need to adjust it via a command line statement. Is there a way to do this in Windows or a utility that can do it for me?

    Basically, I am looking for a solution that would allow me to set brightness to 90% or 30% (examples) in a command script. The computer will be unattended and I cannot foresee what power plan might be in place.

    Solutions? Thanks in advance.

    Soho I don't know if this will be of any help - I don't understand it fully myself and I would be doing some back ups before I tried any of it.

    Can I force a greater screen brightness from Windows Command Prompt - Super User
