History of Monitor
A long time has passed since the first computer monitors were introduced. Way back when these units were first introduced, they were available in monochrome only and most of the computer monitors used to have a bright green display on a jet black background. These were known as monochrome monitors and they did not use to have high quality displays. The displays that we see on the monitors are caused by the electrons directed on a phosphor coating on the screen by the cathode gun of the picture tube.
To put it simply, the computer monitor comprises of a display device along with the circuitry required to form a display using the signals sent by an external source. The computer monitor receives the signals sent by the CPU of the PC and displays the same on the surface of the monitor. In the old days, the computer monitors were available in just one size, 14 inches. As times passed on the developers of computer monitors saw the problems that the end users were facing due to the onscreen resolution and also the quality of display.
Apart from these problems the old computer monitors were not smart enough to display smooth pictures, in fact the first generation computer were not designed to display images since there were no applications at that time that could output images. Charts and pie images came far later on. Most of the work required during those days were linear in nature and used to be displayed using a series of fine lines. Even a circle was constituted of fine straight lines and if one has access to old computer monitors, they will see the circle as a jagged image. Even the CPU’s available during that time were simple ad did not have the capacity to do the amount of number crunching that is required for displaying graphic images.
As the CPU’s became more and more powerful, so did the programs running on them and hence the demand for better quality computer monitors kept increasing. Keeping graphics in mind the first color
