Woah!  I'll have to test this out, that's an impressive number.

Bart is right though, CRTs have different power consumption 
characteristics than LCDs.  In fact, on an LCD showing all white pixels 
can actually consume less power than showing all black, since to 
display all black, maximum current has to be applied to the LCD itself 
to block the backlight.  An all white display lets the LCD "relax" and 
not block any backlight light.

Thanks for the suggestion.
