6 Alignments and Adjustments
Switch the monitor on and warm it up for 15 minutes.
Display a crosshatch pattern on the screen.
Convergence errors should not exceed the values listed below.

As shown in Figures 6-11 the two CRTs used in
SyncMaster 17GLi monitors use the following
magnet configurations:

Use the following steps to correct any static
misconvergence:
1. Locate the pair of four-pole magnet rings.
2.
Unlock the rings and rotate the individual
rings (change the spacing between tabs) to
converge the vertical red and blue lines.
3.
Rotate the pair of rings (maintaining the
spacing between tabs) to converge the
horizontal red and blue lines.
4,
After completing the red and blue center
convergence adjustment, locate the pair of 6-
pole magnet rings.
5.
Rotate the individual rings (change the
spacing between tabs) to converge the vertical
red and blue (magenta) and green lines.
6.
Rotate the pair of rings (maintaining the
spacing between tabs) to converge the
horizontal red and blue (magenta) and green
lines. Don't rotate the 2-pole magnet because it
is for purity adjustments.
7. Mark the correct position for the magnets and
apply a small line of glue to hold the magnets
in place. Lock the rings in place.
