    I just got a new Mac attached to my LCD. By default the colors are very, very dark. After a calibration it looks perfect. However the Login screen still looks like it did previously.

    How do I apply the calibration to the Login screen?

    AFAIK, you can't. Custom calibrations are associated with users. But does it really matter?

    It's supposed to be like that?

    I have noticed if you have a custom calibration the login screen goes to default and full brightness before you log in and after you log out. It goes back to "normal" and the screen brightness adjusts automatically once you've logged in.

    A little annoying, but no biggy.

    The brightness is full no doubt... but the gamma is set so low that it looks horrible. Kinda like your TV if the color is set at the max. It almost looks like there is such an over abundance of color and black that it darkens everything.

    I guess my LCD is just not happy with the settings.

    Have you tried adjusting the LCD's settings? My Sony LCD has options to choose things like gamma settings, brightness, contrast, etc. Perhaps adjusting your monitor's default gamma will make things better during the login process. (Mac default gamma is 1.8; Windows is 2.2. So, if your monitor is miscalibrated, it could appear too light or too dark prior to the calibration kicking in.)

    What kind of a mac did you get? At work we got a mini and the DVI VGA adapter was faulty so the colours were all screwed up. Replaced the adapter and everything was fine. Are you using an adapter for your computer-monitor connection?

    I got the mini for my kitchen desk. It is using the adapter. I will check out the monitor settings to see if it is using a different gamma. Teh LCD was previously used on a Windows 2000 PC. So maybe it auto configured for that computer.

    I'll let you know what happens.
