Using C# or C++ how can you change a computer monitor's color and brightness settings?
<p>How to change computers colour settings and screen brightness?</p>

<p>I'm creating an application and part of it I want to be able to click a button to change the screen brightness of your monitor.  I also want to be able to change the colour settings so I can flick from colour to black and white/grey scale.</p>

<p>I was originally going to use .NET but I really don't think that's possible at all.</p>

<p>I can't work out how to actually change a computers settings.  Can anyone help?</p>
