9. Raster position adjustment (static convergence)
Adjustment preparation
(1) Position adjustment — This will move an entire color.
Use this adjustment to match colors at the center of the screen. (Active video center from external signal and
physical screen center should now match from phase adj. 8.)
(2) Use the buttons below to switch color to adjust.
"100" - Green (Set green first then move red and blue to match green.)
"O" - Red
"FLASHBACK" - Blue
Adjustment procedure
(1) Press the B button. Extra horizontal lines appear to confirm position mode.
(2) Use the cursor buttons to adjust position.
(3) Press B again to exit raster position mode.
Notes: (1) Other functions cannot be accessed when in raster position adjustment mode. Press B and confirm extra
horizontal lines disappear to exit raster position mode.
(2) Press ENTER to switch between all colors displayed or adjustment color and Green only.
10. Convergence point adjustment (dynamic convergence)
Adjustment preparation
(1) Select color to adjust.
"100" - Green
"O" - Red
"FLASHBACK" - Blue
(2) Use 4,6,2 and 5 to move the cursor position (dotted lines).
(3) Use cursor buttons to move the convergence point.
(4) Three adjustment modes are available:
1. (3x3) Press "100" 5 times
2. (7x5) Press "O" 5 times
3. (13x9) Press "FLASHBACK" 5 times
For touch-up, only the (13x9) mode is necessary. This will adjust every
cross-hatch intersection point on the screen.
For complete adjustment, start with (3x3) mode. This will adjust center
point and eight edge points only, but will greatly reduce adjustment
time. Then use (7x5) mode, and finally (13x9) mode to finish
convergence.
If "S" distortion appears between cross-hatch lines repeat (7x5) mode
to change calculation process while adjusting to remove distortion,
then return to (13x9) mode to finish touch-up convergence.
