Abstract: The circuit is for compensating the corner distortion of frame caused by widely varying vertical frequency by adjusting range of vertical frequency. The circuit comprises a first unit for filtering and integrating the vertical output generated by a vertical deflection IC (IC1), a second unit for varying resister value of a variable register according to the varying amount of vertical frequency to eliminate the distortion, and a third unit for overlapping the varying amount of horizontal frequency and the vertical frequency wave form by a current control to compensate the side pin cushion.
