Calibrating your monitor doesn't mean it renders color correctly. It means that it renders it according to certain standards. Well, obviously, but it's better than nothing. -- W . | ,. w , "Some people are alive only because \|/ \|/ it is illegal to kill them."

Your Spyder will not give accurate results on narrow spectrum devices like LED backlit displays, or even some LCDs with CCFLs or DLP and LCOS displays. It depends greatly on the relation of the filters in your colorimeter to the filters in the display, and the spectrum of the source. To accurately measure many of the newer displays like the LED lit and the new laser based DLP sets, you really need a spectrophotometer with very fine resolution, preferably in the 1 nM range. Tristimulus colorimeters like the spyder and all of the Sencore probes are rapidly becoming less useful. Leonard |
