A method and network are described for correcting vertical non-linearity and mis-convergence in a color television projection system. The correction method includes adjusting the height of the projected image so that proper convergence is attained at either the top or at the bottom of the image, and so that the opposite end of the image is stretched. The stretched end of the image is compressed to proper size and proper convergence by shunting current away from each of three vertical deflection yokes included in the projection system.
