Techniques to customize a user interface for different displays are described. An apparatus such as an electronic device with a processing system may implement a custom user interface system that when executed by a processor is operative to adapt a user interface view of an application for presentation by one or more displays. The custom user interface system may comprise, among other elements, a user interface adaptation component operative to receive as input a user interface view of the application for presentation on a first display and an adaptation parameter, and modify the user interface view for presentation on a second display based on the adaptation parameter. A presentation component is operative to present the customized user interface view on the second display. Other embodiments are described and claimed.
