I'm a vision engineer.
For a project I use a computer with an Intel 82915G controller, integrated on the mother-board.
For technical matters, I had to set, by software,the level (brightness) of the VGA signal produced by the 82915G controller.
This is possible with the Control Panel (Display/Property/Graphic adapter/Colors ...), so I think it should be accessible from my software (written in Microsoft C++).
Do you know a simple access, from software, to that specific VGA controller setting ?
Thanks for your answer.
