Your projection TV has three color
projection tubes-one for red, one for
green, and one for blue. When mixed
together in the proper proportion, the
output of these three color tubes can
produce many colors. To produce
these colors, however, the beams
must be precisely aligned over each
other so that the colors can be mixed.
The process of aligning these picture
beams is called setting the
“convergence”.
Over a period of time, the picture
tubes can drift out of alignment due
to normal bumps and vibrations or
moving the TV. If you move your
TV or if, after a time, you notice
colored rings or halos around objects
in the picture, you may want to
converge (align) the colors.

To simplify convergence, an
screen menu is provided that allows
you to display a test pattern of four
lines on the screen. Properly
converged, the lines appear
white-which is actually a
combination of the outputs of the
three color tubes. The position of the
green lines is stationary. The
positions of the red and blue lines are
adjustable. When properly adjusted,
the red and blue lines should lie
directly over the green lines to
produce single white lines.
