Zusammenfassung:	A method for reducing reflection when operating a head-up display of a motor vehicle. The head-up display includes a covering disk element and a dimming element for dimming a deflected light beam of ambient light. A control device determines a light beam path of the deflected light beam, determines a current position and orientation of the dimming element, and determines a region to be kept free of the deflected light beam around the eye point of a user. Based on this, the control device determines whether the deflected light beam passes through the area to be kept free. If so, the control device generates a control signal for adjusting a position of the dimming element to dim the deflected light beam with an adjustment device, and the adjustment device adjusts the position of the dimming element depending on the control signal.
