A video mirror system for a vehicle includes an interior rearview mirror assembly with an electrochromic reflective element having a front portion and a rear portion generally opposite the front portion. The reflective element has an electrochromic medium disposed between a first substrate and a second substrate and has a transflective third-surface mirror reflector. A video display is disposed to the rear of the reflective element and emits light when actuated that passes through the transflective mirror reflector.
