C Linearity
The C Linearity function corrects for gradual non-linearity between the top
and bottom or left and right sides of the display image. Examples are shown
below. In the first example the top of the image increases in vertical size
while the bottom decreases in vertical size. In the second example the right
side of the image increases in horizontal size while the left side decreases in
horizontal size.
Select C Linearity from the Geometry menu.
It is best to have a screen full of characters
displayed. Or use one of the internal test
patterns available by pressing . If there is
a vertical non-linearity, press
or until
the characters at the top, middle, and bottom of the screen have the same
vertical size. If there is a horizontal non-linearity, press
or until
the characters at the left, middle, and right of the screen have the same
horizontal size.
S Linearity
The S Linearity function corrects for vertical and horizontal non-linearities
which extend from the center of the display to the top and bottom or left

left and right characters are much smaller in size than the center characters.
