Systems, devices and methods are described including receiving a policy from a secure storage device, where the policy may be used to implement collaborative rendering of image content. The image content may include multiple portions of image content. The policy may be used to determining rendering assignments for multiple mobile devices where the assignments may specify that a mobile device is to render one content portion while another mobile device is to render another content portion. The rendering assignments may be provided to the mobile devices and rendered output corresponding to the different content portions may be received from the mobile devices. The rendered output may then be assembled into one or more image frames and wirelessly communicated to a remote display.
