The profiles are being properly recognized and used, but the video card is
not being automatically flashed with the correct LUTs for the screens. Log-in,
Start-up, or reselection of the profiles, as you noted, will reflash the video
card and correct this situation. So will activating the appropriate monitor
calibration software, such as OptiCAL. Since OS X runs applications so
effectively in the background, I can simply leave OptiCAL running, even when I
don't
have a calibrator attached, and bring the application up to use the
"Calibration
Enabled" checkbox to flash the video card more quickly and conveniently
than any other work around that I've found.
Please note that hot connecting monitors, as you describe, is not
recommended... if you follow the rules and shutdown before connecting, then
this problem
will not occur.
