Convergence adjustment of the LCD panels.
Every LCD panel has 6 adjustment screws. By turning these screws
you change the relative position of the panels and converge the
image.
Always start with the adjustment of the green panel. When the green
image is correctly focused, it will later on be used as the reference
image to converge the red and blue image.
Next alignments have to be done :
You have to adjust the green panel until the indicated lines on the
screen are focused (sharp lines). Continue with the blue panel and
adjust until the blue lines coincide with the green lines. Than continue
with the red panel until the red lines coincide with the green lines.
Follow the next procedure to adjust the LCD panels.

The pattern shows lines of one pixel.
Near six lines on the displayed pattern, a screw is drawn with a
number next to it (e.g. if displayed in green = corresponding with the
screws and numbers on the green LCD panel).
When turning a screw in the direction marked by the arrow above the
displayed screw on the screen, the line on the screen moves in the
direction of the straight arrow.
