A mobile computing device comprising a processor and a memory, the memory comprising at least one module comprising computer readable instructions which when executed by said processor causes said mobile computing device to perform the following operations comprising: establish a paired connection with at least one target screen via at least one of a wired and wireless communication interface, wherein the target screen is a screen that is not integral to said mobile computing device; transmit at least video information generated by at least one of an application executing on said mobile computing device and an operating system, OS, executing on said mobile computing device to said target screen over at least said paired connection; wherein said mobile computing device lacks an integral display; characterized in that: said at least one module further comprises a device pairing module having computer readable pairing instructions which when executed by said processor cause said mobile computing device to establish said paired connection at least by the performance of pairing operations comprising: causing said mobile computing device to transmit a request message to the target screen, the request message configured to cause the target screen to transmit an identifier and a connection key to said mobile computing device in response to receipt of the connection key by the target screen as an input; and causing said mobile computing device to determine the identity of the target screen from at least said identifier, to validate the connection key against a local copy of the key and to terminate the pairing operations if validation of the connection key fails; said at least one module further comprises an access control module having access instructions which when executed cause said mobile computing device to perform access management operations comprising transmitting an access token to the paired target screen, wherein the access token specifies a degree of access to resources of the computing device available to the paired target screen. establish a paired connection with at least one target screen via at least one of a wired and wireless communication interface, wherein the target screen is a screen that is not integral to said mobile computing device;
