What is a Monitor? How to choose the best one?

We have already discussed what is a computer? And the monitor is a part of the computer.

In the olden days, computers don’t have monitors. But now, whenever you see a desktop computer, there must be a monitor. Laptops are coming with inbuilt monitors.

First, you need to know the meaning of a monitor.

What is Monitor?

A Monitor is nothing but a display to a computer. We can give input, see the work progress, and we get the output in a digital format. If we don’t get the required output, we can change the input on the screen to get the result that we need. Without a monitor, the computer is incomplete.

Who invented the Monitor?

Karl Ferdinand Braun, a German scientist, invented the monitor in 1897. It is a type of Cathode Ray Tube with a fluorescent screen. This type of monitor is only used in Industries, military, and scientific applications only. The common people are too far to use this monitor because of many reasons like high cost, lack of awareness, low production, etc.

But the computer was invented in 1822. So, it took seven and a half decades to assemble the parts of the computer.

In the olden days, monitors have very limited features like math calculations, sending and receiving messages.

The monitor can weigh up to 5 KG or even more. So, it is not possible to shift frequently. With time, technology also upgraded.

Types of Monitors :

There are different monitors. Based on the purpose of using, we can select the perfect one for our work. My suggestion is to use up-to-date monitors. They have the latest version of ports and so the work experience is great. These are the top 5 different monitors. Let’s see them one by one because you only choose the best after you know them.

  1. Cathode Ray Tube (CRT)
  2. Liquid Crystal Display (LCD)
  3. Light-Emitting Diode (LED)
  4. Plasma Display
  5. OLED Display

Cathode Ray Tube (CRT) :

The Cathode Ray Tube is one of the old techniques used in monitors. But we can still find this type of monitors in Government offices and some other rare places. The first display doesn’t provide many colors. They developed technology and brings the High-Resolution CRT display.

To make the CRT display like a color display, we need to connect the antenna terminals. After several changes, in 1981, IBM introduced a Color Graphic Adapter that displays four colors with a resolution of 320*200 pixels. In the 1980s, the CRT display capable to give ultra HD (1024*768) resolution.

The major drawback with the CRT display is, they consume more space. And the weight is unbearable.

Liquid Crystal Display (LCD) :

We can simply say that LCDs are the competitors to CRT displays. In the 1990s, LED displays are widely used in computers and laptops. High Dynamic Range enabled in LCD monitors to improve color accuracy. Widescreen monitors became very popular in late 2000. Still, we are using LCD monitors because of these prominent features.

  • Auto power-saving enabled in LCDs
  • HDR display
  • Low cost compared to other displays

But when compared between CRT and LCD, LCDs costs high because of quality features.

Light-Emitting Diode (LED) :

The LED displays have semiconductor PN junction diodes. LED displays don’t have fluorescent lamps as their back-light like LCDs. Instead of that, LED displays have LED backlights.

The LEDs consume less power compared to LCDs and CRT displays. And yet they are more costly than the other two types.

Plasma Display :

A plasma display has small cells to create an image. So, they don’t need any special backlight for illuminance. The first 32-inch display is a plasma display.

They are more costly than LCD, LED, and CRT displays.

Organic Light-Emitting Diode Display (OLED):

An OLED display is the present generation display. It is also called an organic electroluminescent (Organic EL) diode. It doesn’t need any back-light separately.

They are coming with high visual clarity with ultra power-saving mode. Because of these reasons, the cost of OLED screens is high in the market. We can find the high refresh rate monitors in this type.

Monitor Ports :

A monitor port is a place where we can put the cable. Each port has a unique feature. We can not insert a port cable to another port on the monitor. Only like ports can have the function (like or unlike). If we want to put one port cable to another port on the monitor, we must use the adapters in the situation.

A monitor must have different ports. A good monitor has multiple up-to-date ports.

This is my LCD monitor (Dell U2412Mc). It has the best feature ‘auto power-saving’. I like this feature because If I have any work to do outside, I let the system be ON and be itself.

I previously set my display to enter the power saving mode after 5 minutes of inactivity. So, I don’t need to worry about my PC power wastage.

In the image, you can see the different ports of my monitor. And these are the listed ports.

  • HDMI Port
  • Display Port
  • VGA Port
  • DVI Port
  • Ethernet Port
  • USB Type-A

Uses of Monitor :

While coming to uses, we live in a digital era. I think the name ‘digital era’ came after we using digital monitors or displays only. We have a lot of uses with digital monitors. I place the best uses down here.

  • We read and gain knowledge with the help of monitors.
  • We can see whatever happening on the corners of the planet or space too.
  • Watching movies, videos, programs, etc, gives entertainment.
  • For gamers, a monitor is the most favorite thing on a computer (Used for awesome gameplay).
  • By using the internet, we can virtually contact our friends and relatives. And for business meetings also, it is helpful.

Conclusion :

The monitors are compulsory to the present generation of computers. But in the future, they may be optional or replaced with the upcoming technology.

If you are reading this on your desktop PC, comment below the best feature of your monitor.

I hope you find this article informative. Share it with your friends.
