Abstract: A rearview mirror assembly for a vehicle includes an electro-optic mirror element that reflects images from the rear of the vehicle, wherein the reflected images may be dimmed in response to a detection of glare from trailing vehicle; a display positioned behind the mirror element for displaying images of a rearward scene; a user input for receiving user adjustment of an extent to which the mirror element is to be dimmed to reduce glare from trailing vehicles; and a processor coupled to the mirror element and the user input for adjusting the extent to which the mirror element is dimmed in response to user adjustment via the user input. Wherein, when user adjustment is made via the user input, the processor causes simulated images of vehicle headlights to be displayed on the display where the simulated images are dimmed to a level selected by the user.
