Vertical:
• Vertical slope (VSL) Align the vertical centre of the picture
to the vertical centre of the CRT. This is the first of the
vertical alignments to perform. For an easy alignment, set
SBL to ON.
• Vertical Amplitude (VAM) Align the vertical amplitude so
that the complete test pattern is visible.
• Vertical S-Correction (VSC) Align the vertical linearity,
meaning that vertical intervals 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).
• H60 Align straight horizontal lines if NTSC input (60 Hz) is
used i.s.o. PAL (50 Hz).
• V60 Align straight vertical lines if NTSC input (60 Hz) is
used i.s.o. PAL (50 Hz).
