There's one LUT in the monitor that's set by the screen controls 
and another in the video card that's set by the calibration data 
from the display's ICC profile. Some high-end displays allow 
loading the monitor LUT with the calibration data from the 
computer but AFAIK that's only possible with proprietary 
software in Windows or MacOS.
