DisplayKit is a framework that wraps around CoreGraphics in order to provide a Cocoa "native" interface to display capturing, resolution switching and gamma fading. DisplayKit may also be used to retrieve a list of all connected displays and get the individual attributes of each, such as color depth, screen width and height, and the corresponding CoreGraphics display ID, among others.
Version 1.0.1 fixes a bug in the example app and incorporates new shell script build phases to streamline building and usage of the framework.
