I ran the Windows 7 color calibration tool, but it won't stick. Sure enough, after calibration color will be changed for a while, but sooner or later, mostly sooner, it reverts back to the default, which makes white look like pi** yellow. I located the Windows 7 color management settings and profiles, which I find hugely confusing and, for the casual user, completely unnecessary. All I want is to tame the yellow tint of the panel, but it always reverts back at some point, even before a reboot, which wipes the settings for sure. Has anyone else had trouble with this? I have a suspicion the Windows 7 color management may be competing with the Intel display driver, which also has color adjustment options in it. Those won't stick either. I reduced green contrast; which workd initially, but after Windows 7 color calibration it still says green contrast is reduced when it's not. As soon as you move the slider a fraction them, bam, the Intel settings are re-applied, but they just won't reliably stick thereafter.

On a side note, the panel is so poor that you can't accurately reduce green anyway. When you do, because of the slightly different viewing angle between the top and bottom of the display, the top looks too red, while the bottom looks still too green. What you really need is a color gradient adjustment tool to compensate for this panel, which would take out more green from the bottom of the display than the top. I don't suppose anyone ever heard of such a thing - at the display driver / color management level?

The Intel calibration settings and Windows colour management settings do seem to conflict with each other. Modifying any Intel setting causes the Intel profile to take over until the Windows 7 calibrator is re-run. What sucks about the Intel one is that the gamma doesn't go below 1, which is the major problem for me.

My solution has been to prevent all Intel graphics programs from starting using MSCONFIG, and avoiding messing with the Intel graphics control panel altogether. This lets me keep my Windows 7 calibrated profile as the one it always uses.
