A video mirror system for a vehicle comprises an interior electrochromic rearview mirror assembly having a reflective element that has a front portion that faces generally towards the driver of the vehicle when the interior rearview mirror assembly is mounted in the vehicle and that has a rear portion that is generally opposite the front portion. The reflective element comprises a transflective mirror reflector that preferably is at least about 15 percent transmitting to visible light incident at the rear portion of the reflective element, and that preferably is at least about 60 percent reflective to visible light incident at the front portion. A video display screen is disposed to the rear of the reflective element and emits light when actuated that passes through the reflective element to be visible to a driver of the vehicle.
