The RASTER patterns consist of 8 full field color patterns at 100% amplitude. The colors
displayed are: White, Yellow, Cyan, Green, Magenta, Red, Blue, and Black.
RASTER patterns are useful for checking color purity and uniformity. Color purity problems
are often caused by the magnetization of some parts inside a CRT display device. This often
results in areas of color on the white raster pattern. Use the three primary color raster patterns
(Red, Green, and Blue) to check for missing and defective pixels on a LCD monitor. Missing
and defective pixels are common problems on this type of display devices.
The Red, Green, and Blue raster patterns are valuable for adjusting the three separate guns
that generate these three primary colors inside a display monitor. A full field display of each
of the eight individual color RASTER patterns also simplifies the analysis of hue and
saturation problems.
