Abstract
Size control circuitry allows the selection of a number of different combinations of raster heights and widths for a video display apparatus. A raster size selection signal is decoded to determine one of a number of possible height and width combinations. The height is determined by varying the vertical size feedback signal to the vertical deflection circuits. The raster width is determined by varying the operation of a side pincushion correcting diode modulator circuit.
