Monitor calibration and default hardware white point

I am trying to generate a color profile for my monitor using the Adobe Gamma that comes with Photoshop (I have version 7). I have already spent a lot more time on this than I intended — searching the Internet for tutorials and resources on the subject, and I just want to generate a general-purpose color profile; e.g., my needs aren’t specific to print, web, video, etc.

I have downloaded canned ICM profiles for my monitor targeted at 5000, 6500, and 9300K. Most resources seem to indicate that a color temperature of 6500K is desirable for most purposes. However, the default hardware color temperature that my monitor is set to is 9300K. Am I supposed to change my *monitor* temperature to 6500K in addition to the software settings? Because when I do, the screen looks awfully dark and yellow — not at all what I am used to. And I would assume that the factory defaults would be a closer baseline to what is most comfortable to the eye.

But anyway, could someone please tell me if this is the correct procedure to calibrating the monitor through Adobe Gamma for 6500K:

1.) Change my monitor from the default setting to 6500K
2.) Load the 6500K canned ICM in Adobe Gamma as the starting point
3.) Calibrate from there

When doing so, I noticed several strange things:
1) The phosphors are listed as "custom" but I am almost positive it is Triniton, and 2) the Gamma value is listed as custom instead of "Windows Default" with a value of 2.50. 3) The hardware white point is listed at 5000K. Oddly, I repeated the same steps using the default 9300K monitor setting and 9300K ICM, and the values are the same.

FWIW, the monitor I have is a 21 inch CRT, IBM 6558 P202; it’s manufactured by Sony from what I’ve read.

Any help would be much appreciated. I am really new to color management and right now I don’t have much time to invest in learning, but would like to at least generate at least a *reasonably* optimized color profile that is better than not nothing, which is what I have now.

Thank you.

leave it that way – (if it’s original profile for your monitor)

and 2) the Gamma value is listed as custom instead of "Windows Default" with a value of 2.50.

? set to windows default – 2.20

3) The hardware white point is listed at

set to 6500

AFAIK
