NextScheme's command-line arguments

NextScheme*.exe [] [-Help] [-?] [/?] [?] [-Next] [-Economy] [-Typical] [-Performance] [-GetBrightness] [-SetBrightness "<UniqueString>" [level] <Value>]

  • [] - Equals to -Next
  • -Help, -?, /?, ? - Show help
  • -Next - Switches to next power scheme (including custom ones)
  • -Economy - Switch to «Power saver» scheme, if available
  • -Typical - Switch to «Balanced» scheme, if available
  • -Performance - Switch to «High performance» scheme, if available
  • -GetBrightness - Returns monitor list for which brightness control is enabled in Battery Mode.
    Response format:
    • <N>. <Name>: "<UniqueString>"
      • Levels: <Level>:<Brightness>, ..., <Level>:<Brightness>
      • Current level: <CurrentLevel>
    • <N> - Monitor's index (unsorted)
    • <Name> - Monitor's name as shown in «Control the brightness monitors» menu
    • <UniqueString> - Monitor's unique string enclosed in double-quotes
      Example of external monitor: "Dell U2312HM (Digital - DVI); T=1; LI=0; PI=0".
      Example of internal monitor: "DISPLAY\LGD0290\4&205f4e7&0&UID67568640_0; T=0"
    • <Level>:<Brightness> - Brightness levels with corresponding values.
      Example: Levels: 0:0, 1:10, 2:20, 3:30, 4:40, 5:50, 6:60, 7:70, 8:80, 9:90, 10:100.
      Monitors do not support brightness values between the levels, so it is recommended to use levels to set brightness
    • <CurrentLevel> - Current brightness level
  • -SetBrightness - Sets brightness level for monitor, which has brightness control enabled in Battery Mode.
    Syntax:
    • -SetBrightness "<UniqueString>" [level] <Value>
    • "<UniqueString>" - Monitor's unique string enclosed in double-quotes
      It should be taken from -GetBrightness output
    • [level] - If defined, the value is interpreted as brightness level, otherwise as brightness value
    • <Value> - Brightness level or value

    Example: set internal monitor brightness to level 3
    NextScheme64.exe -SetBrightness "DISPLAY\LGD0290\4&205f4e7&0&UID67568640_0; T=0" level 3

    Example: set external monitor brightness to 30%
    NextScheme64.exe -SetBrightness "Dell U2312HM (Digital - DVI); T=1; LI=0; PI=0" 30
