4.3.9. Centering (Red and Blue)
Red and blue are now centered horizontally and vertically to match green
as closely as possible.
To Center Red and Blue:
1. Use the H
IDE KEY
to unhide R. Verify that R and G are both on the
screen with B hidden.
2. Access C
ENTERING
from the G
EOMETRY MENU
.
3. Toggle the RGB
KEY
to select R.
4. Use the arrow keys and center red to overlay the green as closely as
possible. If there is an error between the red and green lines, use the
arrow keys to adjust red. Differences between the sides or top and
bottom errors will be split. Balancing this error makes it easier to
perform convergence later. Strictly matching the center may cause a
larger error on one side than the other making convergence harder.
5. Toggle the RGB
KEY
to select B.
6. Use the H
IDE KEY
to unhide B. All three (3) colors should now be on
the screen. This step can also be performed with only B and G on
screen.

and Red lines.

and hide B. Be sure that R and G are both on the
screen with B hidden.

closely as possible. If there is an error between the Red and Green
lines, adjust Red to split the error difference between the sides or top
and bottom.
