Monitor Brightness RRS feed

  • Question


  • I want to control the monitor brightness using APIs. I tried using IOCTLs and WMI interface which is exposed in Vista.

    IOCTLs- IOCTL_VIDEO_SET_DISPLAY_BRIGHTNESS
    WMI - WmiMonitorBrightness and WmiMonitorBrightnessMethods

    But looks like WmiMonitorBrightnessMethods.GetInstances() always return null
    OR
    CreateFile with \\.\LCD always return FIle Not found.

    I tried it on desktops and mobility systems (laptops) but has same issues. Any ideas on how to solve this problem?
