The invention relates to a combined instrument display device for installation in a motor vehicle, and a drive device with which the position of the display device relative to the vehicle can be modified so as to allow for glare-free reading. The position of the display device is modified automatically by an installed electronic circuit that controls the drive device subject to defined parameters. The parameters may be measuring values of light sensors and/or motion sensors mounted on the vehicle and/or values that are determined by an evaluation unit using a database.
