title: Windows: How to change monitor's backlight brightness
body: <p>Ever since I've been using an external monitor with my laptop, when I need to change the backlight brightness I have to press the monitor's buttons to navigate through its menu and adjust the brightness.<br>
  That is really a pain. It's too many button presses! When I was using my laptop's integrated monitor, that was as simple as presing the <code>Fn</code> key plus a combination.</p>
  
  <p>Probably some of you might think it is not possible to change that programmatically. I thought that too. But I've just found a control (a GUI control) in my video card configuration that does exactly that.<br>
  So, that proves it is possible to change this programmatically.</p>
  
  <p>But I can't find any tool or utility that does that. All what I've found are tools that adjust gamma, brightness and contrast. But backlight brightness is a different thing.</p>
  
  <p>Does any of you know how to adjust that damn thing programmatically in Windows?</p>
