Instance Property


The current maximum color component value for the screen.


var maximumExtendedDynamicRangeColorComponentValue: CGFloat { get }


If no content on screen provides extended dynamic range (EDR) values, the value of this property is 1.0. If any content onscreen has requested EDR, the value may be greater than 1.0, depending on the capabilities of the display hardware and other conditions. Only rendering contexts that support EDR can use values greater than 1.0.

When the value changes, didChangeScreenParametersNotification is posted.
