21 Different Types of Computer Monitors


There are many types of computer monitors on the market today. From LED monitors and LCD models to the outdated CRT monitors and today’s technology that has provided us with plasma panel monitors, Quantum dot (QLED) display monitors, and OLED Display monitors, you have plenty to choose from.

Most people in today’s world of technology use computer monitors daily at work, at home, and at school. Monitors are available in an array of designs, shapes, colors, and sizes. About a year ago, I was in the market for a new monitor. The monitor I had been using I had purchased more than a decade before but it finally stopped working. I was really sad because it was huge and I loved it.

As a reporter and freelance writer, I use my computer on a daily basis for many hours per day so it was important for me to find another great monitor that I really enjoyed using. I looked up all the different styles and types of monitors but the main selling point for me was the size. I made the decision that I wanted a 27” monitor although even larger ones are available.

That one seemed to be the perfect size for me and is the same size as the one I had for all those years that had finally stopped working. Although the one I had was an HP brand computer monitor model, this time I decided upon a Dell brand and it is working out really well. If you are also in the market for a new monitor or just want to learn more about them, this article is for you.

The History of Computer Monitors

Computer monitors have been around for about 70 years, beginning with the invention of touch screen technology by E. A. Johnson in 1965, although it did not really catch on at that time. In 1973 the Xerox Alto computer was released on March 1, 1973, which came with the first computer monitor. This particular monitor featured CRT technology and sported a monochrome display.

In 1975, George Samuel Hurst created the first resistive touch screen display but it was not actually produced and put into use until 1982. We have all heard of, and possibly used if you are old enough, a McIntosh Computer which was developed by Apple. The first model was produced in 1976 when the Apple I and Sol-20 computers hit the market. These were the first computers to feature a built-in video output port which allowed for a computer monitor or video screen.

In 1977, James P. Mitchell unveiled LED display technology but LED monitors did not become available for purchase to the average consumer for three more decades. Also in 1977, the Apple II, was produced and provided the first color display on a CRT monitor.

By  1987, the first VGA monitor, the IBM 8513, was released and in 1989, the SVGA standard for computer displays was officially defined by VESA. In the mid to late 1980s, color CRT monitors could produce a 1024 x 768 resolution display and about 1995, one of the very first LCD monitors became available for desktop computers. One of the first models on the market for purchase was the Eizo L66, which was manufactured and released by Eizo Nanao Technologies.

In 1997, IBM, along with Apple, and Viewsonic, began to develop color LCD monitors that offered comparable or even better quality and resolution than the CRT monitors. In 1998, the Apple Studio Display was one of the earliest and affordable color LCD monitors for desktop computers.

In 2003, LCD monitors became more popular than CRT monitors for the first time and by 2007, LCD monitors consistently outsold CRT monitors. At that time, they became the most popular type of computer monitor to purchase and use for millions of people.

Jeff Han offered up the very first interface-free, touch-based computer monitor in 2006, and in 2009, NEC became one of the first companies to manufacture LED monitors for desktop computers. Their first one was called the MultiSync EA222WM and was released in late 2009. By 2010, several companies, including AMD and Intel, began to phase out their support for VGA.

Touch screen LCD monitors began to become a more affordable option for the average consumer in 2017 with prices for 20 to 22-inch touch screen monitors dropping below $500.

In today’s world of technology, LCD monitors, many of them many widescreen models, are common throughout the PC industry.  Because the prices have dropped so much, many people are using dual-monitor setups.

From LED monitors and LCD models to the outdated CRT monitors and today’s technology that has provided us with plasma panel monitors, Quantum dot (QLED) display monitors, and OLED Display monitors, you have plenty to choose from which can be confusing and time-consuming to research. We have made it more simple for you by creating the information and list all in one place so your computer monitor shopping experience can be easier than mine was a year ago.

I am happy with the monitor that I chose and I hope that you will also find the monitor that works best for you, your needs, and your preferences. Not only is my monitor large but I was also able to obtain a widescreen version which I am really enjoying and use on a daily basis. Whether you want to use your monitor for your home office, at your business, for your college classes, zoom meetings for work, or for your kids’ school projects, there is a monitor for you out there.

Also, if you are a gamer or if you create videos for online sites, such as YouTube and Twitch, and have the need for several monitors, there are many versions to choose from including dual monitors.


There are five types of computer monitors and below is a list with options of each type.

CRT (cathode ray tube) Monitors

These monitors use CRT technology to produce the picture on the screen and are more commonly used for creating television screens. These monitors use a stream of intense high-energy electrons that then forms the images on a fluorescent screen. In essence, a  cathode ray tube is a vacuum tube that contains an electron gun at one end and a fluorescent screen at the other end.

CRT monitors are still being used in some organizations and companies but most offices have quit using them because they’re bulky, heavy, and expensive to replace when they breakdown. This type of monitor will eventually be completely phased out.

You can no longer purchase CRT monitors at online stores or brick and mortar ones that are brand new. You can find one sometimes at a garage sale, thrift store, or flea market but otherwise, it is very hard to locate one. If you have a CRT monitor you want to sell, you probably can sell it but you’re not going to get much money out of it because they are not worth much money. The LCD computer monitors replaced CRT monitors over a decade ago so most people just pitch them in the trash when they are retiring their old systems and equipment and swapping it all out for brand new.

LCD (liquid crystal display) Monitors

This is a very popular type of computer model in today’s world. It is compact and lightweight and does not consume as much energy as CRT monitors. It can even run on batteries which makes them also great for laptop models along with desktop. The image is transmitted by these monitors are clear and have very little flicker. The disadvantages include a relatively high price tag, image quality that is not always consistent if you view it from different angles, and the monitor resolution is not always constant which can reduce the performance level.

LED (light-emitting diodes) Monitors

The latest type of computer monitor, the LED monitor is the latest type of monitor to hit the market and are most often used today by consumers. This type of monitor features a flat panel or slightly curved displays which make use of light-emitting diodes for back-lighting, instead of cold cathode fluorescent (CCFL) backlighting used in LCDs.

These monitors use a lot less electricity than the CRT and LCD monitors so they are considered more environmentally friendly. They also produce images with higher contrast and are more durable than the other two types of monitors. They feature a thin design which makes them convenient to place on your desk and they do not produce as much heat as the other types of monitors do while they are running which is great in the summertime if you do not have air conditioning in your office, or not very good air conditioning, which is a bonus.

One of the drawbacks is that they can be a little more pricey, especially if you’re going for one of the more high-end monitors that are on the market today that feature a curved display.

Plasma Display Panel Monitors

This type of monitor uses small cells of charged gases to create the image on the screen and these cells can be likened to the fluorescent light bulbs we use in our homes and offices. Each plasma cell creates its own illumination.

This eliminates the need for a separate backlight and gives PDP monitors strong contrast but this type of monitor is normally heavier than the LCD monitors. Plasma screens also use more electricity than LED and LCD monitors which means they are not as environmentally friendly and are more susceptible to “burned in” images if the monitor is left on for extended periods of time.

Five FAQs about computer monitors:

Is IPS better than LED?

Televisions with LED-backlit features use less power and provide, generally, a brighter picture. In-Plane Switching (IPS) technology is simply another type of LCD TV technology and provides more accuracy in the images while producing the picture and have more vivid color from more narrow viewing angles.

What is the most common type of monitor?

Liquid Crystal Display (LCD) units are the most common kind. They are utilized with mobile devices as well as desktop computer monitors and laptops. They have many advantages, such as high energy efficiency, better brightness, better lighting, and they have a thin, flat design that is very convenient for most people because they take up less desk space.

What are the two basic categories of monitors?

The two basic types of monitor technologies that are available to consumers are CRT monitors and LCD monitors. There are big differences between LCD and CRT, and while LCD technology has advanced to the point where its viewing quality is comparable to CRTs, many people today still choose to purchase a CRT monitor.

The only drawback is CRT monitors are extremely hard to find and are not really produced any longer. They can be found at places like flea markets, garage sales, and in places, such as eBay, online garage sale sites, and thrift stores.

Do monitors have memory?

Yes, as a matter of fact, they do. Many modern monitors do have memory in them but this type of memory is not used for the same information that’s handled in the computer itself. The monitor’s memory is simply used to control the monitor’s behavior and does not affect the computer at all.

What is a monitor called?

Most often, computer monitors are known simply as your monitor but sometimes they were referred to as your computer screen or a visual display unit (VDU).
