5 Convergence adjustment
About convergence
Even though the purpose of the 21XLP -2 Light Probe is to measure and calibrate
colors, the software furnished with it allows you to get full control of the DDA cx3r-
rection system of your Brilliance 201CS display, including the digital convergence
correction section.
As already discussed in Chapter 1, the DDA correction system works by dividing the
screen into a 16x16 matrix and with the ability of controlling the beam position for
each of the resulting 256 areas. By using the
Convergence option of the 21XLP -
2 application software, you can refine by yourself the convergence virtually at any
point of the screen and then save your adjustment in the monitor memory.
As a matter of fact, convergence of your monitor has been already set for the best
performances in our factory and should not require any further adjustment, being a
parameter that normally does not show drifts due to picture tube aging.
However, you can check the performances of your monitor by activating the
Test
pattern option, available from the Convergence pop up menu of the 21XLP -2
application.
NÖTE: Convergence check should be performed only after 30 min. monitor ‘warm

First, a Red-Green-Blue crosshatch pattern will be displayed; if you click the OK but­
ton in the small dialog box then a White crosshatch will be displayed. Click OK again
and the last pattern, a Magenta (red + blue) crosshatch, will appear.
All of them are suitable for evaluating the convergence of your display; if you notice
some areas where performance could be improved, then proceed with the conver­
gence adjustment.
