Gamma Control lets you quickly adjust the gamma correction curve of your Mac’s display. Use it to calibrate the screen for new ambiant conditions without having to go to the ColorSync Calibration Assistant in System Preferences.

Gamma Control can also be used to simulate the effect of various screen calibrations on pictures and videos. You can save your gamma settings in documents and reopen them as needed to reproduce various conditions over and over.

You can easily toggle on or off the application of Gamma Control’s settings to the screen through a hotkey or by clicking on its dock icon.

The changes you make in Gamma Control are not permanent and the default gamma correction curve will be restored when you quit.

Gamma Control is used by designers and photographers to improve the reliability of the colors on their screen. Other professionals adopted it to match the screen color temperature with the lighting on film sets, for when a screen is put in front of the camera.


- Hold on the shift key while dragging the red, green, or blue slider to move all three together.

- Calibrate one screen at a time by setting the Affected Screens setting in Gamma Control’s preferences to “Screens touching control window”.


Release Notes:

• Fixed an issue where some preferences would not work in the English version of the app.
• Added saving and opening setting files in the menu under the app icon when put in the menu bar.

Very useful both with internal and external monitors - I've used this app for many years and now am glad to be able to purchase and support the author. Great utlity for adjusting the gamma on your screen and generally brightening up video, games, etc.. If you are constantly frustrated by the lack of any brightness controls in iTunes or quicktime player then you will want to pick this up to help brighten up your videos and make them even more enjoyable.

This is an AWESOME app! - please make it so i can use the Up and Down arrow keys to adjust my Red Green and Blue values while my cursor is in the corresponding field. That would be even MORE AWESOME!

Review by FliinS

Well done but some bugs may bother - This app changes the monitor's Gamma perfectly but can't work with icc well enough. When connecting external monitor to Macbook: icc setting on built-in monitor (Color LCD) will be ignored (shift to RGB) even when I made no change to Gamma Control for the built-in monitor. This bug can be temporary solved by keep the System Setting app open in background but icc will be ignored again when an app quit (quitting almost any app can cause this). Please fix this bug quickly !
