What Are Monitors And It’s Types – Everything You Need To Know In 2022
Monitors are a critical component of a computer system. There are many different monitors available for consumers to purchase.
But the three main categories are:
- CRT
- LCD
- LED
You can find many variations of each type of monitor.
In the early days of computing, most people used CRT monitors, which were heavy and bulky.
These days, the most popular monitor is an LCD Monitor.

There are different types of LCD monitors which can be categorized based on their functionality or size.
The smallest LCD monitors are called “portable,” They often have an 8-inch screen size.
For example, before purchasing an LCD monitor:
It is important to know size, resolution, contrast ratio, brightness level, price point- all these factors can help you decide which monitor is best for you.
Three Main Types Of Monitors
The monitor is the focal point of every computer and is a vital part of any setup.
To create a smooth and easy user experience, your monitor must be set up to fit your needs.
Here are some different categories for monitors that will help you find the perfect one.
1. CRT Monitors

In the modern era of technology, many people enjoy a faster and more advanced computing experience.
Advances in computer hardware and software afford these experiences.
CRT stands for “Cathode Ray Tube,” an older technology.
CRT monitors have been out of production for being outdated, making it difficult to find these models.
This trend has made CRT monitors (Cathode Ray Tube) an outdated piece of equipment that is no longer necessary.
However, some applications still need a CRT monitor, such as projecting on a screen for a conference or lecture.
They’re better at handling static images, such as PowerPoint slides with graphs and charts.
How Do CRT Monitors Work?
In the early 1900s, cathode ray tubes (CRTs) began to be used for large and small screen televisions.
A CRT consists of a vacuum tube that contains an electron gun at one end, a fluorescent screen that emits light at the other end.
A set of magnetic coils and electrostatic lenses to control the electron beam as it travels between the two ends.
The electron gun is powered by the flow of electricity from a power supply.
2. LCD Monitors

There are many types of monitors, with the LCD monitor being one of the most popular.
They can range in size and resolution and come in various brands. A wide variety of factors go into making a good monitor.
LCD monitors are becoming increasingly popular amongst consumers due to their demand.
It has become a more affordable option for PC users looking for bigger screens and lower prices.
However, these monitors do not have drawbacks, such as having less color depth than LED screens.
This type is typically known for its sleek design, making them great for desktop computers.
However, they serve a variety of purposes besides the home.
One of the most common places to find LCD monitors is in places with high-priority security, such as banks and airports.
These large displays provide customers easy access to flight schedules, banking information, and even food items.
They are also used in museums to broadcast tour information or help visitors better experience the art that is on display.
How Do LCD Monitors Work?
LCD monitors function by passing a current through a liquid with a pair of electrodes.
When the current passes, the liquid’s molecules change shape and reflect light from their surface.
This reflection creates an image inside the monitor with a backlight for illumination.
The images are created by pixels, which is how LCD monitors produce color.
Unlike traditional CRT monitors, LCD monitors don’t have any toxic gas or radiation produced by CRTs.
3. LED Monitors

Over the last decade, LED monitors have become more popular in today’s day and age.
They are becoming more affordable for manufacturers while still retaining high-quality image capabilities.
LEDs also provide power savings for consumers by using less electricity than traditional monitors.
Recently, these monitors have been gaining traction among consumers.
They offer a variety of significant advantages over traditional LCD and CRT screens.
One of the biggest benefits is that they use less power than traditional screens.
For example, the LG 34UM95 monitor only uses a maximum of 60 watts on normal user settings, while LCD monitors can use upwards of 100 watts or more!
This helps laptop owners reduce their battery life on extended trips where outlets might be hard to come by.
How Do LED Monitors Work?
LED monitors work by using light-emitting diodes to display images. This type of monitor does not have a fluorescent screen.
They use an array of LEDs capable of emitting light in very specific wavelengths.
The pixels are then configured in a matrix capable of displaying each pixel in the desired color.
Conclusion
A monitor is a device that displays information from a computer or other electronic device.
There are different monitors for specific uses, such as a CRT monitor, an LCD monitor, and an LED screen.
While many different types of monitors are available on the market.
They all serve the same basic function: to display the information coming from your computer or other electronic devices.
The type of monitor you purchase will depend on what you plan to use it for.
