Chris Cox Nov 23, 2011 3:26 PM (in response to coinup001)WIndows 7 doesn't really have automatic color correction - it just provides information and calculations for applications to use.
When you calibrated, Windows set the video card LUT to correct the white point and gamma curve to your desired settings. And the calibration program saved a profile describing that calibration and how your display produces color. Then applications can use that profile to correct document colors to your display colorspace (but not all do).

twenty_one Nov 24, 2011 3:09 AM (in response to coinup001)Same principle. It seems to me everything is working as it should.
"Monitor calibration" is actually two things: calibration and profiling. Calibration is just a basic correction to bring the monitor in compliance with a few parameters such as temperature, gamma, neutral color balance. But it doesn't do anything about how the monitor actually reproduces color - it cannot change the position of the RGB primaries in three-dimensional color space for instance. This is particularly visible with a wide gamut monitor such as the Eizo.
In short, calibration is not color management.
Color management comes with the second part, profiling. The calibration software makes a monitor profile describing how the monitor behaves, in detail, in its calibrated state. Whether the calibration is achieved via video LUT or monitor LUT doesn't matter (but monitor LUT is usually more accurate).
A color managed application such as Photoshop then converts on the fly to that monitor profile, taking into account gamut and everything else. But Explorer is not color managed, so it just sends the RGB data straight to the (calibrated) monitor unchanged. But it doesn't compensate for the full profile.
Put it another way: Calibration takes you some of the way, and the profile fills in the rest.

CSS Simon Nov 24, 2011 3:28 PM (in response to twenty_one)But don't use Windows 7 calibration. The i1 software does calibration (and profiling also), and it does the calibration much better than W7 calibration (which is done by eye, rather than by colorimeter). Once you've calibrated and profiled with the i1, don't do W7 calibration as well, which will nullify the i1 calibration.
