I don't know, since I don't use videocard utilities... (for the  
reasons previously explained)

The utility is probably lowering your luminance in the video LUTs,  
which we need to control to manage your color. Due to this becoming a  
more common situation, we plan to offer control of the luminance in  
this manner in our software, in a future update, so that users can  
have their cake (or luminance control), and eat it too (or calibrate  
it too...)

Guidelines are to set to defaults. If you find that too exaggerated a  
starting point, then adjust down before calibration; that will reduce  
what we have to do.

What "management" do your displays require? Typically there is nothing  
needed that doesn't happen at the OS level (arrangement, mirroring off  
etc...), plus color management.
