1. A computer-implemented method, comprising:
receiving, by a mobile device, an indication of a display resolution of a remote display that is connected to an infotainment system;
determining, by the mobile device, that at least one of the display resolution of the remote display and an aspect ratio of a pixel of the remote display differs from a supported resolution of the mobile device and a supported aspect ratio of a pixel of the mobile device;
rendering, by the mobile device, a frame for display on the remote display display, the rendering comprising:
determining a dimension of a resolution for the frame, the determining the dimension being based on a product of: i) a dimension of the display resolution of the remote display multiplied by ii) a dimension of the aspect ratio of the pixel of the remote display, and
selecting a portion of the frame, the portion being in the supported resolution of the mobile device, the selecting being based on the dimension of the resolution for the frame and on the display resolution of the remote display, wherein the portion substantially maximizes an area of an image in the frame; and
