let the display burn-in for a 100 hours before trying to do/calibrate critical work. The CCFL tubes will mellow out a bit.
I understand that the CCFL tubes may "mellow" after some number of hours of use, but I don't understand why you can't get a reasonably close calibration before that (and then not be surprised if the monitor drifts from that initial calibration as the tubes "mellow").
I just got a new NEC PA 241W with the Spectraview II software and NEC branded calibration puck. I plugged the monitor in and calibrated it and the screen has a greenish color cast. I spent a couple of hours researching this issue on the web and found this thread (which I had read previously) and made all the suggested tweaks to the software suggested by Jeff Schewe. I did another calibration and the monitor still has a greenish cast.
Previously, I was using an Eizo CG21 calibrated with ColorEyes DisplayPro and a DPT-94 and it looked great compared to the new PA 241W. I uninstalled ColorEyes DisplayPro just to make sure there would be no conflict with the Spectraview II software.
I know I shouldn't expect two different monitors using two different software packages and two different calibration instruments to look the same, but the thing is that whites in my prints printed on my Epson 4900 through Imageprint using IP profiles look white on the print and they looked white on my Eizo, but when I look at the printed image in Photoshop on my new PA 241W, the whites have a greenish tint (after making J. Schewe's suggested tweaks to the Spectraview software and recalibrating). There's no way I can do accurate color correction using this monitor.
BTW, I just checked and the white I'm referring to in my image has RGB values of 240,240,239 in Photoshop, but looks green on my monitor.
It just doesn't seem to me that this problem is going to slowly go away by itself after I let the monitor burn in for 100 hours.
Any help would be appreciated.
