Convergence Adjustment
Convergence adjustments affect both the horizontal and vertical lines of the setup
pattern. These adjustments are performed on the red image while superimposed on
the green image and then on the blue image while superimposed on the green
image.
Start with the coarse convergence adjustments and finalize with the fine conver-
gence adjustment.
The screen area is divided into 25 areas.
Coarse Convergence Adjustments
Highlight ‘Red on Green’ under the coarse convergence item and press ENTER.
The coarse convergence menu will be displayed.
The following items are possible:
* Horizontal sides: adjust the vertical lines, within a certain area, on both sides
without influencing the lines on the middle of the image.
* Vertical corners: adjust the horizontal lines in the four corners, within a certain
area, without influencing the middle of the image.
Repeat for ‘blue on green’
Horizontal sides

coarse adjustment of the red or blue vertical lines in ZONE 3 and 5 simultaneous-
ly.
Hint
* Look to the outside edges of the image and adjust until the red or the blue verti-
cal lines are on the green lines or as close as possible to the green lines.
* During these adjustments, the horizontal convergence adjustments in ZONES 2,
3, 4, and 5 will be set to midposition (barscale 50)
