•
Vertical Amplitude (VA)
Align the vertical amplitude so
that the complete test pattern is visible.
•
Vertical S-Correction (SC)
Align the vertical linearity,
meaning that vertical interval of a grid pattern must be
equal over the entire screen height.
•
Vertical Shift (VSH)
Align the vertical centring so that the
test pattern is located vertically in the middle. Repeat the
'vertical amplitude' alignment if necessary.
•
Service blanking (SBL)
Switch the blanking of the lower
half of the screen ON or OFF (to be used in combination
with the vertical slope alignment).
