Abstract
An arrangement that compensates for a tendency in a raster width of a display screen of a video display or television to increase when a variation in a beam current occurs, decreases an amplitude of a deflection current to decrease in a nonlinear manner as a function of an increase in the beam current. At a low beam current, a given increase in the beam current produces a decrease in the amplitude of the deflection current that is substantially greater than caused by the same increase at a high beam current.
