It appears that the officially promoted VESA way of setting up internal
monitor LUTs takes too long. Now many manufactureres use USB instead. 
Indeed a standardised path for getting these calibration information would 
be highly desireable. Manually reading OSD is not so nice.

That remembers me on the MCCS (VESA Monitor Control Command Set), which 
I would like to see supported inside libXcm. Might be a GSoC project idea.
