My new 2690wuxi2 has been up and running for two days, and I absolutely love it. Either I had no idea my Apple Cinema Display was that bad, or had aged that much, even with regular calibration, or the technology has obviously improved that much. Regardless, my library of 1Ds Mark III photos looks like I bought a Phase back. Suddenly my stored sharpness settings for many files are too sharp when viewed on the 2690, compared to the old ACD. The NEC is at the factory default of 26.3% sharpness, which seems reasonable for text and photos, but now how do I determine how much is too much sharpness for the other viewers in the world who are not fortunate enough to have such a wonderful display for viewing? Do people run two or three systems in order to check? I do have a Dell laptop I could cross check with, but that is time consuming. Would I over-sharpen on the 2690 and assume ~90% of viewers are using a inferior display technology? How do you manage?
