Devices, systems, and methods are presented for shutting down the 3D effect of active shutter 3D glasses by synchronizing the transparency of the lenses with respect to each other when the 3D glasses have been rotated beyond a threshold angle. The threshold angle can be pre-set through a user-selectable switch. Transitioning from an alternating shutter mode to a synchronized shutter mode can include a fade in which the duty cycles of the lens are adjusted. Direct measurement techniques for measuring the differential roll angle between the lenses and left and right eye images on a display are disclosed.
