What is Monitor (Technology) definition/concept/elaboration

Monitor is a device where users can communicate with their computer by receiving data. It has gone through several stages since its birth, evolution , continuously offering new improvements, until reaching the modern LED technology of today.

A computer is basically a data processing center operated by a user; this relationship necessarily involves means of input and output of information , that is, the interfaces, the monitor being a means of transmitting information that can be assimilated by the user. Prior to the appearance of the monitor, this communication it happened through several lights and later through telex. It wasn’t until the seventies that monitors began to appear through IBM’s innovative vision. Thus, came the single-color cathode ray tube monitors with the mere ability to show text and then give way to color monitors and the ability to show graphics. Linked to these improvements were developed graphics cards, capable of expressing the graphics on the device, starting with CGA and passing through EGA, VGA and SVGA.

The monitors also vary in the possibility of size offered to the market, as well as in relation to their appearance. A monitor’s size is measured from one of its vertices and its aspect ratio is between height and width.

Another important point when considering a monitor is the maximum resolution it can offer and the way it has to display the subpixels. In the latter case, it is worth noting that each pixel is formed by subpixels of three different colors: green, blue and red; depending on the monitor, they are arranged in different ways: triangles or lines.

In addition to pixels, other technical aspects to consider when talking about a monitor are: the response time or latency, which measures the time it takes a pixel to go from an active state to an inactive one; the dot size, which is no more than the space between two single-pixel phosphors and reveals the sharpness of a monitor; the usable area or area used for the image; the angle of view, from where you can see the image without being blurred or blurry; and finally luminosity.

It is expected that monitors will continue to evolve in the future and be able to show improvements from the past as a result of the constant innovation process experienced.
