Board index » Windows Vista » Color Management: Vista won't hold a custom ICC profile

Windows Vista32
I have an HP Pavilion dv2000 laptop running Vista. I used a Spyer2Pro to

calibrate my monitor and use the accompanying ColorVision program to load the

resultant ICC custom profile as the default color profile via the Vista

startup routine. The profile loads fine, and the color switches to the

custom profile. After two or three minutes, however, the colors switch back

to the uncalibrated Vista default profile. Only a reboot will load the

custom profile again. Any ideas? HP was no help. Thanks in advance.

Hi Globetrotter



This appears to be a common problem with Vista and ICCs - possibly a bug.

The ICC will load, but then the Gamma Look-Up Table will be reset following

a number of different actions. See for example:



neosmart.net/blog/2007/windows-vistas-gamma-table-bug/" >neosmart.net/blog/2007/windows-vistas-gamma-table-bug/



As far as I know, there is no bug number and no hotfix yet. Note that it may

be highly dependent on your graphics card hardware and driver, as well as

the Windows-supplied colour profile functions (unconfirmed).



As suggested in the above blog, running the DisplayProfile utility may be a

workaround.



The Colour team at Microsoft have a blog site here:

blogs.msdn.com/color_blog/default.aspx." >blogs.msdn.com/color_blog/default.aspx. You may be able to contact

them directly to see if they know about the problem or the solution.



Good luck with it,
