The History of The Monitor
The begining of the computer monitor
Then came the IBM'S CRT
In 1981, IBM introduced the first PC, also known as a "three-piece computer" because the monitor, keyboard and cpu were separate, rather than earlier computer terminals, which combined the monitor and keyboard. With the PC's introduction came the Colour Graphics Adapter (CGA) from IBM, allowing for four colours. The CGA allowed 320 x 200 resolution. By 1984, IBM introduced the Enhanced Graphics Adapter permitting 16 colours and a 640 x 350-pixel display.
