Create custom reference modes for Apple Pro Display XDR on Mac

On your Mac, you can create custom reference modes for your Apple Pro Display XDR. You can tailor these modes for your specific workflow needs by setting color gamut, white point, luminance, and transfer function options.

Note: Reference modes are intended to be used in controlled viewing conditions typically found in professional content production environments. Using a mode in the incorrect viewing condition or with the wrong media type may produce unsatisfactory results.

To change these preferences (available only when you’re using an Apple Pro Display XDR), choose Apple menu > System Preferences, click Displays, click Presets, click Customize, then click the Add button .

Option				Description
Preset Name				Enter a name for the custom reference mode.
Description				Enter a description for the custom reference mode.
Color Gamut				The primary colors used in the reference mode to define the gamut. P3: The wide color P3 primaries used by modern displays and digital cinema projectors. Rec.709/sRGB: The color primaries used for HDTV, the web, and typical computer displays. EBU/PAL: The color primaries used by standard definition TV per the EBU Tech 3213 specification. SMPTE-C/NTSC: The color primaries used by standard definition TV per the SMPTE-C standard.
White Point				Selects the reference mode’s white point target for the display. D65: The CIE Standard Illuminant D65 white point typically used by most displays and in video-related workflows. DCI: The white point defined by the Digital Cinema System Specification. D50: The CIE Standard Illuminant D50 white point typically used in most printing-related workflows. Custom: Use the x and y fields to specify a custom white point.
SDR Transfer Function				The reference mode’s gamma response when receiving standard-dynamic range content. BT.1886 Annex 1: The EOTF used for HDTV production per the ITU-R BT.1886 recommendation. sRGB ICC V2: The piecewise gamma used by sRGB per the IEC 61966-2-1:1999 standard. Pure Power: Enter an exponent to define a pure power gamma function.
Apply System Gamma Boost				Tells macOS to increase the gamma by the specified amount. This may be used to provide either the contrast implied by asymmetrical media encoding and decoding transfer functions found in some media standards, or a contrast boost required when the actual display brightness to surround ratio is higher than that specified in the standard.
Enable PQ for HDR Content				Allows the display to receive HDR content using the PQ transfer function instead of gamma.
Maximum Luminance				Sets the maximum brightness of the display in nits.
Limit Luminance to Full Screen Capability				Restricts maximum luminance to 1000 nits, which the display can sustain full-screen in normal operating conditions.
Backlight Optimization				Prefer Color: Optimizes the display’s 2D backlighting system for the color reproduction of small objects on dark backgrounds over blooming minimization. Prefer Contrast: The default setting. Optimizes the display’s 2D backlighting system for the general minimization of blooming effects.
