Vertical
•
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).
•
Vertical Shift (VSH).
Align the vertical centering so that the test pattern is located
vertically in the middle. Repeat the 'vertical amplitude' alignment if necessary.
•
Vertical slope (VS).
Align the vertical center of the picture to the vertical center 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 Zoom (VX, if present).
The vertical zoom is added in for the purpose of
development. It helps the designer to set proper values for the movie expand or
movie(16x9) compress. Default value is “25”.
•
V60 (Delta VAM for 60Hz, if present).
Align straight vertical lines if NTSC system
(60 Hz) is used i.s.o. PAL (50 Hz). Default value is “-2”.
In the next table, you will find the GEOMETRY default values for the different sets.
