As I understand it the 'blooming' merely means that the LCD transistors are no 
longer being driven.  FYI I see this whenever my LCD is powered off by DPMS, 
it turns off the backlight first, but if I hold my LCD at the right angle to 
the ambient light I see the decay of the charge that held the LCD pixels at a 
particular colour over the next few seconds.  It is not harmful, and I don't 
believe whatever failure mode the old CRT monitors suffered from exists any 
more in an LCD monitor.

I'm also of a mind that the "your CRT will blow up if incorrectly driven" 
thing is more urban myth than fact, although I'm sure there are pathological 
cases in ancient history.  If anyone has any direct experience with trouble 
from "overclocking" your CRT or LCD monitor it'd be interesting to hear it.
