Description
Gamma Control is a Mac OS X application that gives you the possibility to adjust the gamma correction curve of the screen. Use the application to calibrate the screen for new ambiant conditions without having to use the ColorSync Calibration Assistant. You can save your multiple settings in documents and retrieve them when needed. The settings you change are not saved into the current ColorSync profile and are restored when you quit Gamma Control.
Version 3.0 brings a rethought user interface and corrects many bugs present in previous versions. See version history for below for details.
Requirements
Mac OS X 10.2.8 or later.
Known issues
When another application has changed the gamma curve of the screen, default gamma settings resets when it closes. This happend with most screen savers. You will need to click again on Gamma Control’s icon in the dock to reactivate the effect. To work around this problem, you may tell Gamma Control to continuously reapply the correction from the preferences, which will reapply gamma correction each 8 seconds.

Version History
Gamma Control 3.0.3
- Fixed a problem where Gamma Control was unusable under Mac OS X 10.3.9.
Gamma Control 3.0.2
- Fixed a problem where Gamma Control would crash at startup when running on Mac OS X 10.2.8.
Gamma Control 3.0.1
Corrected a bug where it failed to update the gamma settings after a text field was edited, and where some text fields would not accept values in the correct range.
Native support for Mac OS X on Intel processors.
Gamma Control 3.0
User interface
- Added text fields to edit correction values.
- Added color names — red, green, blue — over each slider; before that you had to guess or experiment to find them.
- Replaced the simple mode with an option to show or hide color targets.
- Better VoiceOver support.
Problems have been solved with the option “Affected Screens: Screen touching control window” which should now work as expected.
In previous version, this option worked correctly only when all screens where side-by-side and had the same vertical size (in pixel).
(I would have corrected this before, only until this month I hadn’t a second screen to test Gamma Control on .)
A new preference setting allow the gamma correction to be reapplied continuously.
This should help keeping the gamma correction stable when another application or a screen saver reinitialize it. When this happens, Gamma Control should now reapply in the next 8 seconds.
