oi i have an imac20", some six months old, that, logged in as the normal user, has really bad color contrasting, i.e. the greys are almost white. i've tried fiddling with all the monitor/color settings and played tons with the calibration tool to no avail. figured the screen was shot but then before escalating to support i logged in with the admin-account and alas, it's all perfect there. so it seenms a user-specific issue, comparing the settings didn't bring up anything, both users are running with the default calibration. any ideas anybody what to do? ah, the standard user that has the issue has been imported via setup utility (called migration tool i think)...maybe that could be the root of it? thank you.
