I don?t suppose the Eizo CG243 will be more « stable » than your current NEC
display. So, use the exact same approach.

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.

The daylight color temperature started from ~6350 and ended up at ~6650K


I measured these on my display which I calibrated yesterday (the target was

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...)
