This is a crosshatch pattern that may be called for by some manufacturers' test
procedures. The primary version (shown below) consists of an 8x8 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.
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.
Used with HDCP feature. For more information, see Chapter 13,
