Misha - If the monitor allows you to adjust brightness, contrast and individual RGB balance then you can calibrate it. Gets even better if you can adjust RGB gain and bias, but that's not majorly important. I guess biggest thing would be the angle of view. Does the image color, brightness and contrast change depending on your viewing angle? Most of the current monitor calibration hardware works with both CRT and LCD. From what I've read, new LCD displays are usable for photo processing, but you have to calibrate them correctly - something about backlight intensity has to be set right, but I don't remember what.
