Setting-Up RGB/CGA Video Monitors

“Why is an RGB monitor better than a composite monitor”? This question has been asked over and over again. In simple terms – a composite signal from a computer has every video element that RGB signals have. They are: Red, Blue, & Green video signals, Horizontal or Composite sync and Vertical sync signals which are combined in one video line. An RGB output has separate signal lines for each one of these elements and for that reason provide a sharper video image on the monitor crt.
