SetMonitorBrightness() return true when scalar firmware not support brightness adjustment? RRS feed

  • 问题

  • Hi,

    I am developing a brightness control application on AllInOne computer with windows 8. The scalar firmware don't support adjust brightness by DDC/CI, but when I call SetMonitorBrightness(), it always return TRUE.  What I need to know is, in what conditions, SetMonitorBrightness() will return TRUE. MSDN didn't describe this clearly. it just said "If the function succeeds, the return value is TRUE. If the function fails, the return value is FALSE ".

    Does somebody know detailed information about this problem? please give me your great help.

    Thanks in advance for  helpfull answer.
