Adobe Gamma is a free, visually-based monitor calibration program that is installed automatically when Photoshop is installed on Windows computers. Adobe Gamma can interfere with monitor calibration software.

When you use an X-Rite (Monaco or Gretag included) application for creating display profiles, you should remove the Adobe Gamma Loader shortcut from the Startup program group on your system.

Proceed as follows:

This does not remove the Adobe Gamma Loader program or the Adobe Gamma Control Panel and is quite safe. When you create a display profile with your Monaco software, a shortcut to MonacoGamma.exe will be placed in the "Startup" program group so your profile will load properly.

Warning: Do not resave a display profile created by Monaco software with the Adobe Gamma Control Panel.  The Adobe Gamma Control Panel can alter your display profile if you load and save the profile within it. If your display profile is listed as the default under "Display Properties" - "Settings" - "Advanced" - "Color Management" and (if it) is being loaded by Monaco Gamma at startup, Adobe applications will recognize and use your display profile correctly.
