Changing Screen Brightness/Colour/Contrast RRS feed

  • Question

  • Hi,

    Please can anyuone tell me how to get and change the contrast/colour/brightness settings from the windows display properties dialog in C++/MFC.

    At present I'm using SetDeviceGammaRamp() where I can see the brightness changing, however, when I then manually check what values are set by going to Display Properties->Settings->Advanced->Color this resets it to the default state.

    TIA

  • Changing the monitor properties is completly hardware specific, there is no standard API for that. If you have some sort of SDK (may be provided by the monitor manufacturers) then you can do it.
