X-Rite Eye-One Display Profiling at PMA 2008

I use there program with a nec lcd screen calibrator... Program works great.. love it when I calibrate more then 1 moniter dual moniters once calibrated look so nice..

CIEDE2000 is just an color difference measurement unit, like delta E in Lab. All color difference measurements or better all attemptsto fulfil any color difference standard is useless unless you have calibrated/profiled your output devices (monitors, printers or scanners).

Whats is more important DE2000 results or profiling?
