Even though it is recommended that you calibrate using an external objective measuring device
(colorimeter for emissive color measurements), we provide a way to calibrate your monitor using your
own eyesight if you don't have an external measuring device.
In MacOS X, Apple built-in Display Calibrator Assistant enables you to get a good color casts
from your monitor and to obtain a reasonable solution for your work environment.
Follow these instructions:
1. System Preferences > Displays:
Ensure Colors is set to Millions.
•
Set the Brightness slider to your preferred value (the Apple default is approximately
•
60%, although a slightly brighter level might be necessary on aging displays).
2. Color tab:
Display Profiles: the calibration utility automatically selects by default the current
•
display profile.
3. Calibrate button: select Expert Mode.
4. Native Gamma of the Display:
Adjust the Brightness left slider vertically until the apple symbol fades into the patterned
•
frames. Move the right slider until the shape is neutral compared to its background. You
may need to readjust the left hand brightness slider a little more after this step.
The next four steps are basically a repeat of the first but affect other parts of the gamma
•
curve. You should follow the instructions given by Apple in the dialogs.
5. Target Gamma: the monitor gamma should be entered in the panel, either Macintosh default
(1.8) or Windows default (2.2).
6. Target White Point: check the box labeled Use native white point.
7. The final steps require that you give the display profile a name and the new display profile will be
crated and saved into the appropriate folder for use by the system.
