Yes, why change.....
I use SpyderPro3 and their puck. It was great until I got the NEC PA241-BK. I had been using a HP LP2065m prior. Calibration produced a pink cast. I changed the video card (for other reasons), seemed to help but still annoying. One thing I discovered, trying 2 other software calibration software, is that SP3 can;t read luminance levels, properly. Not a big deal since one sets the luminance/brightness to taste or to match prints.
The past 2 days I have tried CEDP and BasICColor with the SP3 puck. The first gave me a better calibration but still not perfect, to my eyes. I was intrigued by BC's ability to calibrate using the NEC's internal LUT, which CEDP and SP3 could not do. At the end of all of this, I am buying BasICColor.
SP3Pro3 just doesn't seem to be able to properly calibrate the NEC PA241_BK.
I don;t know if it is the puck or software but, whichever software I use, the black point seems to be higher than it should be. Not a big deal. We are splitting hairs here.
