Aspect ratio - choosing the correct matching factor
Today’s picture sources deliver pictures with widely varying formats and aspect
ratios. In many cases the format delivered by the source device does not match
the geometry of your video monitor. The video signals coming from the source
must therefore be adjusted to suit the geometry of your monitor (4:3 or 16:9).
Different conversion factors are required for this according to the source signal
and the monitor. The table printed below is intended to help you establish the
most suitable conversion factor (no conversion, -33V, +33V, etc.) for each
combination of source signal (see ”Video signal format” columns) and monitor.
The illustrations in the table show the picture formats produced by each
combination.
