BNC Connectors
BNC connectors are used with coaxial cable for
improved signal transmission. Better signal
transmission becomes critical at high frequencies,
such as those required for 1280 x 1024 resolution.
Most video boards that operate at 1280 x 1024
resolution recommend using coaxial cable with
BNC connectors. The 5 BNC connectors on the
rear of the monitor can accept Red, Green and
Blue video. Composite sync can be applied
separately, or combined with the Green video
signal (commonly referred to as "composite
sync-on green"). If composite sync-on green is
used, then only 3 of the 5 BNC connectors are
used. The connectors are labeled accordingly.
