Adjusting the convergence
NOTE: before you attempt to adjust the convergence, your system needs to be ‘war­
med up’. Do not calibrate the display unless it has been operating for at least 30 min.
NOTE: every time you run the 21XLP -2 application, the program will be searching
for the Light Probe unit. For this reason, even if the Light Probe will not be used
during convergence adjustment it must remain connected to the system.____________ __
STEP 1
From the 21XLP -2 application window, select Execute calibration from the
Convergence pop up menu. A dialog box will appear indicating saving present
values, while the program is saving the current monitor configuration.
STEP 2
Global convergence adjustment.
NOTE: Global convergence is provided tor screen center adjustment. It you do not
notice convergence errors in this area, just click OK to proceed with next step.
A Red-Blue crosshatch pattern will be displayed at the center of the screen, together
with a dialog box where all the adjustment options for this step are listed.
Two options are available, for both the horizontal and vertical lines of the crosshat­
ch:
(Hor/Ver) R,B
This option adjusts the relative position of the Red and Blue beams so that they can
converge each other. In most cases, once you have assured the convergence of
Red and Blue beams, the convergence with the Green beam is automatically achie­
ved since, due to the gun design, this beam is the central one.
However, due to small gun imperfections, in some cases even if the RB convergen­
ce is adjusted, the Green beam can still be resolved as a single color. If that is the
case, you may use the next adjustment option.
(Hor/Ver) G,M
This option adjusts the position of the Green beam with respect to the position of
the Red and Blue beams together (the combination of which generates the Magenta
