macOS Catalina manages HDR monitors and televisions

The update to macOS 10.15.4 offers a new option in the "Monitor" section of the System Preferences. If you connect a monitor or an HDR TV, the option to select the item "Extended dynamic range" appears in the Preferences. HDR support is not practically limited to the contents of the TV application but extends to the whole system.

The term HDR, we remember it, stands for High Dynamic Range and refers to the possibility of displaying a richer range of colors, brighter whites and very deep blacks (dynamic range) compared to the Standard Dynamic Range (SDR). Some monitors and some TVs support this mode.

In the macOS 10.15.4 release notes, Apple explains that the update "includes HDR (High Dynamic Range) Output support for HDR10 compatible third-party monitors and TVs connected with DisplayPort or HDMI."

To take advantage of HDR displays or TVs, you need cables and adapters compatible with the HDMI 2.0a / 2.0b / 2.1 standard. We can confirm operation with a latest generation Mac mini connected directly to an LG TV that supports the HDR-10 standard, although frankly we have not noticed great differences with and without the High Dynamic Range option enabled.

Even the XDR Pro Displays now support custom reference modes that can be adapted to the specific needs of workflows by selecting from various options for color gamut, white point, luminance and transfer function.
