Well, if the XL20 is used in "Calibration" mode (or in "sRGB" or "AdobeRGB" or 
"Emulation" mode), you won't have a problem with the meaning of the controls 
any more, since in these four operating modes, all controls are locked and you 
can't change them anyway :-)

[and the setup of these four presets (-> target luminance, white point, gamma, 
or emulated profile) is to be done with NCE, not via the OSD menu]
