This crosshatch screen adjusts width and height, static convergence and purity, brightness and focus.
Width and Height
Adjust height and width of the crosshatch pattern until the grid fills the screen. Keep
all the lines visible, though. If part of the grid goes off the screen, then the game image will, too.
Static Convergence and Purity
All lines in the crosshatch pattern must be white. Else, there is a
convergence or purity problem. Slight color tinges at the extreme edges of the screen are okay.
Brightness
Ensure the bars are a fairly strong white.
Focus
Bars with fuzzy edges indicate a focus problem. Adjust the focus control for best sharpness.

Color Screens
These are solid, one-color images that help adjust color drive controls for proper intensity. The screens
are black, white, red, green and blue. Press the Start button to cycle through the screens. The white
screen helps adjust brightness and color output balance.
