A vehicle rearview mirror system includes an electrochromic transflective reflective element, an ambient light sensor operable to sense ambient light, a glare light sensor operable to sense glare light and a control circuit that is responsive to light detection by at least one of the ambient and glare light sensors and that establishes a reflectance level of the reflective element. The mirror system includes a display element disposed behind the transflective reflective element and operable to display information through the mirror reflector of the reflective element and viewable through the mirror reflector by a driver of the vehicle when the display element is displaying information, and substantially non-viewable by the driver of the vehicle when the display element is not displaying information. The system includes a display intensity control for adjusting display intensity responsive to light detection by at least one of the glare light sensor and ambient light sensor.
