MONITOR PATTERNS TEST
MONITOR PATTERNS SUB MENU SCREEN
NOTE: This game uses a medium resolution monitor. The increased resolution means that more video
information is displayed on the screen than with standard resolution monitors. Use of an industrial-grade
degaussing coil is recommended before any corrections to monitor adjustments are attempted.
The Monitor Patterns routine provides test screens to verify monitor performance or make adjustments. To
begin the tests, use the operator control switches to choose Monitor Patterns Menu from the
Diagnostics Menu screen and press TEST to activate the sub-menu. Select a test from the sub-menu
and press TEST to activate it. Press TEST once again to return to the Monitor Patterns sub menu.
Color Bars fills the screen with shades of colors to verify red, green, blue and white level dynamic
adjustments. Each color bar should appear sharp, clear, and distinct from bars on either side.
There are 31 levels of intensity displayed in each of the color bars. Incorrect adjustment can cause detail
to be missing at the top or bottom of a color bar. Set the monitor controls so that the maximum number of
levels is visible in every bar.
The Color Bars screen helps to adjust the monitor brightness and contrast.
Cross Hatch fills the screen with a grid and a series of dots. The grid and the dots should be completely
white, with no fringes or parallel images. The lines should be straight and the dots round.
Consult the service literature from the manufacturer of the monitor for more detail on these adjustments.
The Crosshatch Patterns assist in verifying the monitor convergence, linearity, and dynamic focus.

MONITOR PATTERNS TEST (continued from previous page)
Red, Blue, and Green Color Screen tests fill the screen with 100% of the chosen color at normal
intensity. Each screen should be absolutely uniform from top to bottom and side to side. No retrace lines
or noise should be visible.
The Color Screen tests can verify monitor intensity, black level, blanking and color purity.
Color Screens may not hold their uniformity if the monitor degaussing circuit is defective.
White, Black, 50% Gray, and 25% Gray Screens fill the screen with black, gray or white at various
intensities. The screens should be uniform with no color tints or distortion. No retrace lines or noise should
be visible.
If any of the tests shows a need for adjustment, use the proper controls on the Video Monitor.
