Adjusting the image convergence
Alter the red, green, and blue formatters to overlap the lines to form pure white lines throughout the
image.
•
To shift the panels up and down, adjust the vertical screw.
•
To shift the panels left and right, adjust the horizontal screw.
•
To change the angle of the panel, adjust the twist screw.
The red and green formatters are identical in physical layout and adjuster function. The blue formatter
board differs slightly in physical layout, but the adjustment functions are the same.
Typically the blue image component can be used as the fixed reference, so no adjustment is required.
However if needed, you can adjust the blue image component but you must remove the side panel.
The recommended normal convergence adjustments are from green to blue and red to green.
