Fine-tune the calibration of your display
You can fine-tune the current calibration of your display by adjusting the white point and luminance to more precisely match your own in-house display calibration target. You can fine-tune the calibration of Pro Display XDR, no matter which reference mode you’re using.
To change these preferences, choose Apple menu > System Preferences, click Displays , click Display Settings, click Presets, then click Fine-Tune Calibration.
If Fine-Tune Calibration is dimmed and you’re using a supported Mac, you may need to change the reference mode your display is using. If you’re using a custom reference mode, select Limit Luminance to Full Screen Capability to enable fine-tuning.
White Point (x)
The x chromaticity coordinate as described in the CIE 1931 xyY colour space when measuring a white image.
White Point (y)
The y chromaticity coordinate as described in the CIE 1931 xyY colour space when measuring a white image.
The Y value (luminance) as described in the CIE 1931 xyY colour space when measuring a white image.
Enter an optional description.
Removes an existing fine-tuning and switches the display back to the current calibrated state.
You can also measure the calibration of your display and perform in-field recalibration. See the Apple Support article Measuring and calibrating Apple Pro Display XDR.
