In order to represent an item of three-dimensional graphical information on a display device, in particular of a vehicle, a method calculates a first item of two-dimensional graphical information for at least one first area of the display device from the three-dimensional information using a graphics processor, The display device represents the three-dimensional information in a two-dimensional manner. A second item of two-dimensional graphical information is calculated for at least one second area of the display device from the three-dimensional information using a universal processor. The second area is part of the first area. The method checks whether the first and second items of two-dimensional graphical information have a degree of correspondence which is higher than a threshold value, and outputs the first item of two-dimensional information on the display device if the first and second items of two-dimensional graphical information have a degree of correspondence which is higher than the threshold value.
