You usually don't calibrate a monitor (and most LCDs have no calibration options), you're profiling the monitor. The difference is that calibrating implies that you're adjusting the actual output to fit a certain spec (my understanding is that some CRT monitors could be calibrated because you could adjust the individual colour guns, LCDs only give you brightness control so you can't adjust the RGB output). Profiling involves sending RGB values to the monitor and measuring what colour (in LAB colour) the monitor actually displays. Then with colour management, it's able to convert the RGB values from the colour space you're using into LAB colours, and then use the monitor profile to determine what RGB value needs to be sent to the monitor to create that LAB value on the display.
Por eso los CRT no han sido desplazados aún totalmente y quién tenga un Barco lo atesorará como algo sagrado y quién quiera estar cerca de eso (cerca) tendrá que comprarse un Eizo ColorEdge CG221 o un Nec SpectraView Reference.
