3-2. CONVERGENCE
Preparation:
•Before starting, perform FOCUS, V. LIN and V. SIZE adjustments.
•Set BRIGHTNESS control to minimum.
•Input dot pattern.
(1)Vertical and Horizontal Static Convergence
1.Adjust V. STAT magnet to converge red, green and blue dots in the center of the screen. (Vertical movement)

Tilt the V. STAT magnet and adjust static convergence to open or close the V. STAT magnet.
2.When the V. STAT magnet is moved in the direction of arrow a and b, red, green, and blue dots move as shown below:

Operation of BMC (Hexapole) Magnet
The respective dot positions resulting from moving each magnet interact, so perform adjustment while tracking.
Use the VSTAT tabs to adjust the red, green, and blue dots so they line up at the center of the screen (move the dots in a horizontal direction.)
