title: Is it possible to add display panel brightness support to an existing Windows display driver?
body: <p>So, keep the stock driver, but add some other driver plus Windows register configuration that tells Windows how to do brightness at the hardware level?</p>
  
  <p>Is that even possible within Windows? Or does it need to be built into the graphics driver itself?</p>
  
  <p>(I'm specifically asking about Intel's "Legacy Backlight Brightness (LBB) I/O Register". Which works on a lot of Intel GPUs.)</p>
  
  <p>For reference, I'm not really grokking all the jargon: <a href="http://msdn.microsoft.com/en-us/library/windows/hardware/ff569755(v=vs.85).aspx" rel="nofollow">http://msdn.microsoft.com/en-us/library/windows/hardware/ff569755(v=vs.85).aspx</a></p>
