Male Type Figure 3-2. Male Type 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.
