How They Came To Be
Today's monitors have a long history, spanning from the first personal computer to today's big-screen LCD. Along the way, innovations enabled growth of PCs as well as industries, such as computer gaming. Current LCD computer monitors now outnumber the original CRT screen. Screens now displaying millions of colors for complex graphics began with just two for basic text.
The video display terminal, or VDT, marked the early days of computer monitors. These VDTs included a screen and attached keyboard linked to a larger computer by a serial connection. Because VDTs required a connection to a larger computer, they were often referred to as "dumb terminals." Dumb terminals displayed text only in two colours, usually black and green. The Apple II and first game machines began using a television CRT.
