Was trying to calibrate a 24" aluminum iMac last night and had all kinds of problems. Tried it using both Easy and Advanced modes and nothing seemed to help. Even though I would enter in "Native White Point" the color temperature at the end would always be between 7200 and 7700. Also set it for a target of 6500 and it would still come up high until my last attempt.

Problem was that I still could not use the profile because even though I had the gamut set for 2.2 it would give me higher gamuts ranging from 2.4 to 2.7 which made everything look really strange.

Was doing this in a totally dark room at night so there was no issue with different color temperature light shining on the screen. Anybody have a clue to what is going on?

Is this the glossy screen?

Yes.

I should note that it has been successfully profiled before but it has been several months so was just doing a new one in case of any drift.

Craig,

I guess when you say gamut, you mean gamma? Is luminance set to 140?

Scotti

Yes, I meant gamma. Since it looked so bad I went back to the "Calibrate" function in System Preferences but have the Luminance set to around 140.

I guess the monitor is ok then. Must be something else.

Hi Craig,

did you get my email?

Yes John, still trying to troubleshoot.
