(k) Select 6550°K on the OSD Menu and set the color coordinates in x=0.313, y=0.329 at the
maximum contrast control and center brightness control
(l) Check if a full white pattern is over 30Ft/L.
6. Static Convergence Adjustment
(a) Apply a magenta cross hatch pattern on display.
(b) Adjust the focus from the best over all focus on the display.
Also adjust the brightness to the desired condition.
(c) Vertical red and blue lines are converged by varying the angles between the two tabs of the 4-pole
magnets.
(d) Horizontal red and blue lines are converged by varying the tabs together and keeping the angle
between them constant.
(e) Apply a yellow cross hatch pattern on the display.
(f) Vertical green and red lines are converged by barying the angle between the two tabs of the 6-pole
magnets.
(g) Horizontal green and red lines are converged by varying the tabs together and keeping the angle
between them constant.
