            SHARPNESS

You should set the sharpness of
your CRT to a value that shows
clean black and gray transitions,
with no white ghosting in between.

On most modern displays, the
#Ysharpness#Y control is an
edge-enhancement control, and
most probably should be set to
zero, or in the middle.

In some #YPVM#Y/#YBVM#Y displays
this is also referred to as
#Yaperture#Y.
