Sharpness
As its name implies, sharpness is used to adjust the sharpness control on a display. If sharpness is set too
high, then single pixel black or white lines on a grey
background will appear to have a halo.
The top left of this screen (labels do not appear on the
actual pattern) has a 1 pixel black cross and nearby single
pixel white lines. Wider lines can be used to see the effect of
sharpness control on larger video structures.
