MONITOR TESTS MENU
COLOR BARS fills the screen with colored stripes. Use the Color Bars screen to help you to optimize red,
green, blue level adjustments. You can also use color bars during monitor brightness and contrast
adjustments. Each color bar should appear sharp, clear, and distinct from bars on either side. Press the
ABORT button two times to change the color of the screen border. Press REVERSE to exit.
CONVERGENCE
tests fill the screen with a grid and a series of dots. Use the Convergence Tests while
adjusting monitor convergence, linearity, and dynamic focus. The convergence grid and the dots should
be all one color. Look for fringes or parallel images, which shouldn’t appear. Color fringes in the center
grid or dots indicates a need for static convergence. Color fringes at the edges of the screen indicates a
need for dynamic convergence.
the lines should be straight and the dots round. Curved lines may
indicate a need for side pincushion adjustments. Press the ABORT button two times to change the color
of the screen grid lines. Press REVERSE to exit.
PURITY
tests fill the screen with 100% of the chosen color at normal intensity. Use the Purity Tests while
adjusting color purity. You can also use purity screens to check black level, intensity, blanking and
degaussing. Each screen should be absolutely uniform from top to bottom and side to side. No retrace
lines, color contamination or noise should be visible. Color screens contaminated with other colors
indicate a need for degaussing or purity magnet adjustment. Press the ABORT button eight times to
change the color of the screen. Press REVERSE to exit.
RECTANGLES
tests display solid color boxes over a contrasting background screen. Use the Rectangles
Tests while adjusting vertical height, horizontal width and raster linearity. Each rectangle should be
centered, with all four sides visible. The sides of the background shouldn’t be visible. Press the ABORT
button twice to change the color of the screen. Press REVERSE to exit.
If any test reveals a need for adjustment, use the proper knobs on the Monitor Remote Controls board.
