Interfaces presentations on displays

An example non-transitory computer-readable storage medium comprises instructions that, when executed by a processing resource of a computing device, cause the processing resource to present an interface of an application on a first display of the computing device. The instructions further cause the processing resource to, in response to receiving a selection of a boundary that defines a portion of the interface, present the portion on a second display of the computing device. 一种示例非暂时性计算机可读存储介质，包括指令，当由计算设备的处理资源执行时，该指令使处理资源在计算设备的第一显示器上呈现应用的界面。该指令进一步使处理资源响应于接收对限定界面的一部分的边界的选择，在计算设备的第二显示器上呈现该部分。
