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 red panel and
adjust until the red lines coincide with the green lines. Than continue
with the blue panel until the blue lines coincide with the green lines.
Follow the next procedure to adjust the LCD panels.

displayed screw on the screen, the line on the screen moves in the
direction of the straight arrow.
