Description
This is still another version of a crosshatch pattern
that may be called for by some manufacturers’
test procedures. The primary version consists of
an 8 by 8 white crosshatch on a black background.
A white rectangular patch is added in the center.
The secondary version inverts the image to black
lines and box on a white background.
Purpose
This is a general purpose test image that can be
used to check and adjust video scan linearity and
geometry and color convergence. The large white
rectangle also allows for checking a display’s high
voltage regulation. This is done by observing the
vertical lines at the left and right edges of the
image. They should be fairly straight and not pull
in the area of the white rectangle.
