Methods and systems for an electro-optic filter that operates in two modes-a homogeneous mode and a heterogeneous mode are disclosed in the invention. The homogeneous mode maintains a relatively homogeneous shading/attenuation range across specified viewing angles in both the vertical and horizontal directions. The heterogeneous mode provides for relatively homogeneous shading/attenuation range across specified viewing angles in the horizontal direction but allows for gradual and a more varying (e.g., wider) range of shading/attenuation changes across the specified viewing angles in the vertical direction, e.g., as compared to the horizontal direction.
