maximumPotentialExtendedDynamicRangeColorComponentValue
The maximum possible color component value for the screen when it’s in extended dynamic range (EDR) mode.
Declaration
var maximumPotentialExtendedDynamicRangeColorComponentValue: CGFloat { get }Discussion
The value of this property is determined when you create the NSScreen object, and doesn’t change afterwards. If this property is greater than 1.0, the screen supports EDR values. If the screen doesn’t support EDR values, the value is 1.0.
The actual maximum value might be lower than this property’s value, and can change dynamically, depending on the capabilities of the display hardware and other conditions. See maximumExtendedDynamicRangeColorComponentValue.
