Abstract
A vehicle-mounted terminal and a method for obtaining a resolution of a screen of a handheld terminal are disclosed. The method includes establishing a connection between a handheld terminal having a second screen and a vehicle-mounted terminal having a first screen, mapping a display of the second screen onto the first screen, obtaining a first coordinate difference between two coordinate points on the second screen and a second coordinate difference between two mapped points on the first screen that correspond to the two coordinate points respectively, and obtaining a resolution of the second screen using the relationship that a ratio of the first coordinate difference to the second coordinate difference is equal to a ratio of a mapped resolution of the second screen mapped onto the first screen to the resolution of the second screen, wherein the mapped resolution of the second screen mapped onto the first screen is a first resolution and the resolution of the second screen is a second resolution.
