Hi - We current use Windows XP with no hope of changing anytime soon. This makes color managing our monitors difficult because XP requires admin privledges to write a profile and to apply a profile. (These are two separate actions.) Our security policies do not allow users adlmin rights making color management very difficult. But many of our QA workstations have Eizo or LaCie monitors which allow monitor calibration via the monitor internal LUT rather than the video card LUT. I wonder if either monitor stores current calibration data internally? Apparently the LaCie monitor does because after admin calibration I find no file in the profile directory yet our tests show the monitor is deplaying colors correctly. The Eizo software stores a very small .icm file in the C:\WINDOWS\system32\spool\drivers\color directory, but it doesn't appear to contain full LUT data. So my questions for only Eizo and LaCie monitors calibrated using Eico and LaCie programs and spectros are: Is calibration data stored in the monitor internally? If so, is this sufficient? What advantage is gained through an .icc profile? Thanks, Barry F.
