I don?t suppose the Eizo CG243 will be more « stable » than your current NEC display. So, use the exact same approach. / Roger From: argyllcms-bounce@xxxxxxxxxxxxx [mailto:argyllcms-bounce@xxxxxxxxxxxxx] On Behalf Of János, Tóth F. Sent: 4 octobre 2010 16:42 To: argyllcms@xxxxxxxxxxxxx Subject: [argyllcms] Re: ColorMunki measurement drift I made a little test with my colormunki today. I started with a cold instrument (I stored it on room temperature which is about 21 celsius now) and I finished when I found that it is acclimatsed on the display.

It was powered up all day (in both times) and I waited for the acclimatization as well (in both times). My ColorMunki shows the usual behavior when it warms up: decreasing luminance, increasing color temperature. On the other hand, the acclimatized instrument shows a little drift on the display side as well. I think I can live with it. But... what about a display like the EIZO CG243w? Would I use my colormunki on it if I have one? (Yes, because I want to set up a hardware profile which is different from the factory setups, just like now with the Dell U2410, but if I would use it on the "standard way" like the most users...)
