Your Guide to Buying a Computer Monitor on eBay

Computers have undoubtedly become one of the most integral parts of modern society. Whether one is using the device for work purposes, for research, or for simple personal enjoyment, the capabilities that a computer provides a person are boundless. Computers have essentially created an entirely new world for society, within which a person can find access to virtually any information and the answers to numerous questions. However, computers and their components can be extremely difficult to work with, as they are complex pieces of technology. This can make the process of finding the proper computer monitor for a person confusing and even frustrating. The long list of specifics that must be considered before purchasing a computer monitor can be tiring to look through in detail, although this should still be done prior to buying the monitor.

As a large, diverse marketplace, eBay carries a broad selection of computer accessories, including computer monitors . Although the search may seem daunting, by examining a few essential features of a computer monitor, such as screen size, resolution, panel type, backlights, and connections, any shopper can narrow down his or her choices to find the perfect monitor.

Screen Size

The screen size of a computer monitor is one of the device's most defining factors. There are a wide range of sizes to choose from, ranging from small sizes to wide or tall screens, but some sizes are more popular than others. Many consumers have a tendency to think that the larger the screen size, the better the monitor, but this is not always true. Screen size simply depends on a buyer's preference. Screen sizes are typically measured in terms of the diagonal length of the screen, from corner to corner.

15-Inch to 17-Inch Screens

Computer monitor sizes either at or between 15 inches and 17 inches are typically considered to be the smallest sizes on the market. Because the pricing of computer monitors usually directly correlates with the size of the monitor, smaller monitors tend to be cheaper, and the price can be expected to increase with size. Therefore, the biggest advantage of 15-inch and 17-inch computer monitors is their small price tags. Additionally, these smaller screens do not take up much space on a desktop or table, which makes them ideal for buyers who have limited space. However, their small size can make usage more inefficient and less enjoyable. The functions of smaller computer monitors are often restricted by the limited screen size, and this can end up creating less value for the money spent on the screen.

19-Inch to 20-Inch Screens

The typical next step up in computer monitor sizes is a 19-inch or 20-inch screen. These sizes are often considered to be more standard these days, and there are a plethora of options available from a wide number of brands, including Apple and Dell. Although the price does go up with the addition of a few inches of space, those inches do create a significant difference in usage quality. These sizes offer a good amount of screen space for functions like editing photos and working on multiple documents at once. However, the monitors are not so large that they take up absurd amounts of space in a person's work area.

21-Inch to 24-Inch Screens

The next increase in screen size comes with a steep price increase. However, the display on a 21-inch or a 24-inch screen creates a much more enjoyable viewing experience while in use. These sizes are particularly useful for people who plan to use their computers for gaming, watching movies, and other multimedia functions.

27-Inch Screens

There are very few computer monitor brands that create screens that exceed a 27-inch screen. These monitors require a significant amount of space on a desk or table, along with some deep pockets, as the prices for these monitors can be quite high. These monitors are ideal for users who plan to spend very large amounts of time working on a computer throughout the day. Also, some buyers replace an HDTV altogether by purchasing a large computer monitor, in which case, the largest sizes available are the best options.


Most computer monitors employ a liquid crystal display, otherwise known as LCD. LCD computer monitors use a special type of liquid crystal to create the images that are seen on the computer screen. Essentially, the microscopic crystals determine whether light gets through from the computer's backlight or if it is shut out. These variations of light let the screen's individual pixels express their specific colours. LCD monitors are also considered to be energy efficient, as they use very little energy to power the screen, despite how bright the screen may be.


The resolution of a computer monitor refers to the number of pixels that make up the images that are shown on the screen. Resolution typically varies with screen size, so smaller screens often have smaller pixel resolutions. However, some high-quality monitors may have higher resolutions on smaller screens, so resolution depends on the specific characteristics of the monitor. Resolution is typically measured as the width by the height, referring to the number of pixels in the width and the height of the screen. The higher the resolution, the higher the number of images and text that can fit on the computer's screen.

The resolution that is considered to produce the sharpest and most refined images on a computer screen is the monitor's native resolution, and this should be noted in the instruction manual. Higher resolutions may be of importance to users who plan to use the computer monitor for long periods of time and also for people who frequently use their computers for high-quality photo editing. The following table includes a list of the native resolutions most commonly associated with different screen sizes.

Screen Size

Native Resolution

19 inches        

1440 by 900 pixels

21 inches        

1600 by 900 pixels

24 inches        

1920 by 1080 pixels

27 inches

2560 by 1440 pixels

Most types of monitors can operate at more than one resolution, although this depends on the manufacturer and the monitor quality. A computer monitor's instruction manual should list its available resolutions.

Panel Types

Yet another factor that goes into the decision of which computer monitor to buy is what type of panel the monitor employs. A computer monitor's panel type is indicative of how the computer's different abilities, such as reproduction of colour and responsiveness, function.

Twisted Nematic (TN) Panels

The TN panel type for computer monitors is considered to be one of the most common panels on the market. For many buyers, TN panels are an ideal choice because they are very inexpensive to manufacture, which allows for significantly lower prices. TN panels also have fast response times, which makes them an ideal choice for gamers or other users who are in need of high speeds when using their monitors. The brightness of most TN panels is also considered to be quite high.

However, TN panels have a significant drawback in that they have a narrow viewing angle. This means that when the screen is looked at from different angles, the colours of the screen become distorted. Thus, in order to see the proper colouring, the screen can only be viewed from certain angles.

Vertical Alignment (VA) Panels

In comparison to TN panels, there are both advantages and drawbacks to using a VA panel. Contrary to TN panels, VA types have increased viewing angles, and the brightness levels are much higher. However, the response times of VA panels are slower than those of TN panels. The colour reproduction of VA panels is decent in comparison to TN panels, but VA panels do not have the best colour reproduction on the market, and they also may have much higher price tags.

In-Plane Switching (IPS) Panels

IPS panels are often considered to be of the highest quality when it comes to computer monitor panel types. IPS panels have wide viewing angles with minimal colour and image distortion. They also have high calibre colour reproduction. Some of the newest types of IPS panels originally had some lag in terms of response times, but those functions have been improved over time. Prices for IPS panels are usually the highest on the market, which can be expected given their functionality, but as manufacturers improve their methods for creating the panels, the prices are slowly decreasing.

How to Buy Computer Monitors on eBay

Although computer monitors are some of the most purchased pieces of technology on the market today, there are a wide range of factors that go into deciding exactly which computer monitor is appropriate for a user's needs. Many of these factors are not concepts that are generally known by the average person, and navigating these options can be difficult for shoppers. However, shopping for computer monitors on eBay can take some of the pain out of this shopping process.

Once the specifics of the computer monitor have been chosen, a shopper can move directly to the main search bar on eBay ' s homepage. By entering all the necessary information, he or she can begin to efficiently search for the perfect computer monitor. Even if all of the specifics have not been chosen, the buyer can utilise the filter options provided by eBay to focus a search.

Communicate with the Seller

Given the amount of money that can easily be spent on a computer monitor, it is of the utmost importance for a buyer to feel confident about a purchase. eBay eliminates the possibility of confusion about a product by giving buyers the option to directly communicate with the seller via the "Ask a question" button on all product pages.


Computers are one of the most innovative and prized pieces of technology that have come into use in modern society. The capabilities that they provide to users, from high-tech scientists and engineers to average citizens, make computers a necessity in modern times. Many of the enjoyable experiences that come from using a computer for work or for simple pleasure are directly related to the functionality of the computer's monitor. A wide range of factors go into choosing a computer monitor, and the combination of each of these factors can make or a break a user's experience with a particular computer. Not everyone's needs are exactly the same, and different specs work best for different types of users. A buyer must have some basic knowledge of the different specs in order to choose an appropriate computer monitor.

Although considering all the possibilities may seem daunting, eBay makes shopping for a computer monitor simple and headache-free. The task of understanding a computer monitor is not as difficult as it may seem. By learning about screen sizes, panel types, backlights, and resolutions, any user can successfully find the perfect computer monitor for his or her needs.
