The M41EHN tube is fitted with a rotation control coil. The tilt adjustment in this monitor allows an additional
control of the bottom line (Tilt respectively NS trapezium).
Front of screen performance is further enhanced by means of a brightness-uniformity circuit which can be
switched on/off via I
