Applications:
Center Cross is ideal to center TV monitors and TV screens and alignment of picture
height/picture width. Furthermore, it is used to check the deflection linearity and the pin-
cushion correction. Overcan indications allow precise adjustment of the wanted picture
size. Blurred shown vertical lines point to a bad frequency response and multiple lines
may be the result of reflections.
