Working from home has become a permanent fixture for many people, so selecting the finest computer monitors is more crucial than ever. Meanwhile, many PC components remain in limited supply, making a screen update one of the simplest and most dramatic improvements you can make to your gaming setup right now.

The greatest computer displays in several categories are listed in our post today, as well as all the information you need to know about screens.

Type of Computer monitors

1. CRT (cathode ray tube) monitors

These monitors use CRT technology, which was most frequently employed in the production of television displays. A stream of concentrated high-energy electrons is utilized in these monitors to generate pictures on a fluorescent screen. A cathode-ray tube is essentially a vacuum tube with an electron gun on one end and a fluorescent screen on the other.

While CRT monitors may still be found in certain businesses, many have ceased using them since they are heavy, big, and expensive to repair if they fail. While these monitors are still in use, it would be a good idea to replace them with cheaper, lighter, and more dependable displays.

CRT has been and is still being praised for its realistic image quality, great contrast ratio, and all the great memories of the era when the Internet was invented.

2. LCD (liquid crystal display) monitors

The LCD employs one of the most cutting-edge technologies accessible nowadays. A layer of color or monochrome pixels is often positioned schematically between a couple of transparent electrodes and two polarizing filters. The optical effect is achieved by polarizing the light in different quantities and allowing it to flow through the liquid crystal layer. There are two popular types of LCD technology available: active matrix TFT technology and passive matrix technology, which should be described below:

  • TFT produces higher-quality images and it is more secure and dependable. 
  • The passive matrix, on the other hand, has a sluggish reaction time and is rapidly becoming obsolete.

One of the benefits of LCD displays is their small size, which makes them lightweight. They also use less electricity than CRT displays and can be powered by batteries, making them suitable for laptops.

These displays deliver images that are not geometrically deformed and have low flicker. 

However, this sort of display has certain drawbacks, including a relatively high price, image quality that varies when viewed from different angles, and a monitor resolution that is not always consistent, meaning that any changes might result in decreased performance.

3. LED (light-emitting diodes) monitors

LED monitors are the most recent variety of displays on the market. These are flat panel or slightly curved displays that employ light-emitting diodes for backlighting rather than the cold cathode fluorescent (CCFL) backlighting used in LCDs. LED displays are believed to consume considerably less electricity than CRT and LCD monitors and are far more ecologically friendly.

LED displays offer the benefits of producing pictures with better contrast, having a lower environmental effect when discarded, being more durable than CRT or LCD monitors, and having a very small design. They also don't generate a lot of heat when jogging. The main disadvantage is that they might be more expensive, particularly for high-end monitors such as the newly launched curved displays.

4. OLED (Organic Light-Emitting Diodes) monitors

OLED monitors are flat computer displays that use OLED (Organic Light Emitting Diodes) pixels rather than liquid crystal filled units. OLED technology, unlike LCD (Liquid Crystal Display) technology, does not require illumination to work. When current runs between a cathode and an anode, an emissive layer of organic molecules (e.g., polyaniline, green in the diagram) sandwiched between these electrodes can become lit.

To do this, a layer known as conductive layer made up of organic plastic molecules such as polyfluorene, lies between the emissive layer and the anode. Because the anode is positively charged, it attracts electrons from the conductive layer, leaving the conductive layer with a positive charge that attracts electrons from the emissive layer. In a process known as electrophosphorescence, light is released as a by-product. 

To the commercial world, OLED has been complimented for its thin size, its energy usage and its image quality. In fact, brands are now studying for the thinnest ever display of the best ever color accuracy with even a transparent screen made with OLED technology.

Buying Guide

1. Resolution and Screen Type

Today, the finest displays are still LCD monitors that employ LED technology to create a thin product that saves energy while delivering optimal backlighting. We've been waiting for years for OLED technology to make the leap to PC displays; it's now happening, thanks to companies like LG, although the technology is still very uncommon.

However, one element of PC displays that you must consider is resolution. While 1080p was previously the gold standard, it is now simply the starting point. If you're willing to spend a bit more, there are a few more alternatives to consider, particularly if you want to increase screen area or gaming graphics. However, resolution is not the be-all and end-all of display characteristics. In fact, having too high resolution on a small screen may be aggravating since it reduces all pictures and requires you to magnify everything to read it.

  • 1080p (Full HD): If you want acceptable clarity but want to save money or focus on other, more essential qualities, 1080p is the way to go – as long as the monitor you're buying isn't too big. 1080p is best suited to 21-inch to 24-inch monitors. These monitors provide excellent image quality, and now that they compete with 4K, the costs are rock-bottom. If you wish to go larger than 24 inches, you should consider at least 2,560 x 1,440 resolution, and maybe 4K.
  • 1440p (Quad HD): Despite being the often-forgotten stepchild in the growing marriage of consumers and 4K, 1440p is still the recommended resolution for gamers, since it delivers a considerable boost in visuals over 1080p while without overtaxing your graphics card. It's also considerably less expensive if you want extra features like high refresh rates. It is also known colloquially as Quad HD/QHD.
  • 4K/Ultra HD (UHD): The industry is most eager to push customers toward 4K resolution. With 3,840 x 2,160 pixels, it seems far more detailed than 1080p, and costs have dropped significantly in recent years. To operate a system at this resolution, gamers will require a strong graphics card, and finding inexpensive monitors with complete suites of frame synching support or high-refresh rates is still challenging. However, whether you're streaming or utilizing UHD Blu-rays, there's enough 4K video to enjoy.
  • 5K: This resolution grabbed news when it appeared on Apple's iMac, but it's still far from mainstream even years later. The Dell UP2715K is a beautiful display, but we would suggest several high-end 4K monitors before it because there isn't much of a difference between them.
  • 8K: Some 8K displays are also available, most notably Dell's 8K Ultrasharp. There is no need for a monitor with such a high resolution, although they are accessible for those with the means if resolution is the most essential factor.
  • 16K: While 8K is still a dream for gaming monitors, people are starting to think about the next generation of monitors with 16K screens. When 16K is available, a single monitor would contain the same amount of pixels that a combination of 144 HD monitors do, and the experience is expected to be super surreal.

2. Aspect ratio

The screen's aspect displays pictures in (length compared to height). 16:9 is a popular format and your best bet. It works with a wide range of content and is ideal for movies and games. Some high-end displays prefer to stretch things out with ratios like 21:9, although this is better suited to odd work conditions or intensive gaming. 

Another popular size, 16:10, allows for a somewhat additional vertical room for viewing several open documents or photos. 3:2 aspect ratio is becoming more popular in laptops for improved online viewing, although it is uncommon on stand-alone screens.

3. Brightness

These days, high-end displays have a brightness of 300 to 350 cd/m2. Extra lighting may be beneficial if you operate in a well-lit environment or near wide windows. Too much brightness, on the other hand, is a recipe for eye strain. As long as your monitor's brightness choices exceed 250 cd/m2, you're fine to go. However, if you want one with HDR support, the higher the peak brightness, the better to take advantage of that technology.

4. HDR

High dynamic range, or HDR, is a relatively new addition to the PC display market that may have a significant influence on graphics. However, most PC displays lack the brightness required to really benefit from it, and even the finest ones don't look as beautiful as they could. Keep in mind that there are other HDR versions to consider, such as HDR10+ for more sophisticated material.

5. Refresh rate

The refresh rate of a monitor is measured in hertz (Hz) and indicates how frequently the image on your screen is updated. While most screens support up to 60Hz, some now provide significantly greater refresh rates. 

This can result in better desktop motions and support for higher frame rates in games, 

which can make a huge impact in fast-paced games by lowering input latency. The 120Hz to 144Hz range is a good starting point, but you might go for the quickest displays available, which offer up to 240Hz. So make sure you have a powerful graphics card to support it.

6. Response time

The response time of a monitor determines how rapidly the display’s picture changes. A quick response time is ideal for fast-paced action videos, twitchy games, and other related activities. Response times are measured in milliseconds, with the finest displays capable of switching pixels in a matter of milliseconds, although not everyone requires such quick responses.

This section also has to tell apart two confusing concepts when it comes to time, response time and the refresh rate. Take a look:

  • Response time is the real world time measured in milliseconds of the duration between the point the signal is received and the point the full image is displayed to the users. All the process of receiving signals and displaying the pixels is called a cycle.
  • Refresh rate is measured in Hz, demonstrating the number of times (or cycles) the monitor does the work we mentioned above. Receiving phase and displaying phase would be repeated by the monitor hundreds of times in just a single second. Refresh rate doesn’t just depend on the capability of the monitor but the capability of the processors as well as the cables.

In reality, people care more about the refresh rate than the response time. However, a high refresh rate combined with a super long response time would result in a not-much-better monitor than a normal one.

7. Contrast ratio

Contrast ratios show the difference between how white and dark a monitor screen can become. Higher contrast ratios are a positive indicator since they indicate that colors will be more distinct. However, there are various measures for contrast ratios, and claimed specs aren't always trustworthy, so take everything with a grain of salt.

For traditional LCD screens, the contrast ratio can be as high as 100,000,000:1, but for LED and OLED screens, due to the fact that pixels are turned off when not used, the contrast ratio is n : 0, which goes towards infinity.

8. Viewing angle

The viewing angle of a monitor isn't as crucial as it is for a TV screen, but if you prefer to watch shows on your computer with a group of friends, strive for a bigger viewing angle so people on the sides can see easily. Anything above 170 degrees is considered excellent news in this case.


However, wide viewing angles also pose a new threat for situations when you don’t want outsiders to view your screen and steal your information. Therefore, you need to thoroughly think about this.

Famous Brands

1. LG 

LG makes excellent ultrawides. They also sell 5K displays if you want to melt your graphics card into a puddle. LG has developed a unique software to assist you in splitting your screen. LG's premium UltraWide displays engage you in a variety of activities, including content production and gaming. You can see a panoramic perspective made possible by the extra wide 21:9 IPS display for real color fidelity at broad angles. You can also multitask more easily, rapidly move between programs, and enjoy a complete, unobstructed view.

LG is obviously one of the top brands in the monitor market. They offer monitors with sizes from 21 inches up to 49 inches in the customer section. LG monitors are packed with IPS panels, curved LCD panels, NVIDIA G-SYNC and AMD FreeSync technology in various size forms. However, to guarantee the quality, the prices could be a little higher than other affordable brands.

2. Samsung 

Samsung specializes in curved displays ranging from mid-range to high-end, as well as QLED HDR ultra-high-end products. Be wary of their lack of a stated dead pixel policy; it's simply bring it in and we'll see. It's worth noting that they may make design sacrifices even on high-end items like the 34-inch 1440p 100Hz VA screen. Samsung also provides unique software to assist you in splitting your screen.

Samsung does not give much attention to the gaming section, but they try to focus more on the office section, where they can sell a lot more products than to gamers. With their exceptional customer support centers, they’re proud to be the businesses’ greatest partner.

3. ASUS 

Asus primarily manufactures gaming monitors. ASUS has long been a leader in revolutionary technology, having introduced the world's first consumer gaming display at 144Hz in 2012 and 1440p resolution Nvidia G-Sync displays just two years later. The business has managed to push towards 360Hz, 4K HDR with 144Hz, and increase screen size up to 65 inches while maintaining a 120Hz refresh rate by 2021.

ASUS ROG, ASUS TUF, and ASUS Nitro are gaming lineups that none of the gamer community members isn’t familiar with. ASUS monitors have been made to work seamlessly with their gaming equipment, including laptops, graphics cards, or even phones.

Asus doesn’t seem to care much about the curved screen range. Instead, they tend to develop new technologies with higher refresh rates, lower response times, and better energy usage.

4. Dell 

Top-tier UltraSharp displays are built with cutting-edge design and technology for maximum performance. The UltraSharp PremierColor series is intended for creators and includes tools for color sensitive jobs. These low-cost monitors are designed to tackle everyday difficulties and help you stay on budget. They are designed specifically for world-class collaboration at your workstation and in any meeting place.

Dell monitors are intended for offices and working from homes. Dell monitors are often designed with thin bezels, high quality images, and most importantly, durability. It is nearly everyone in this world that knows that Dell products are very hard to break and made to last. 

Dell monitors range from a few hundred dollars to under $1000, which falls into the affordable range. Therefore, if you’re on a limited budget, Dell should be a great candidate.

5. Acer 

The Acer curved zero-frame display with Full HD resolution provides amazing performance. The stunning 1920 x 1080 resolution brings crisp, true-to-life colors to life, letting you enjoy High-Definition entertainment in the comfort of your own home. The wide view angle technology allows you to share what's on your screen with friends and family since colors remain accurate regardless of viewing angle. 

The incredible 100,000,000:1 contrast ratio and quick reaction time ensure that your games, work, and movies go smoothly and appear spectacular. With Adaptive-Sync Technology, the game's frame rate is set by your graphics card rather than the monitor's predetermined refresh rate, offering you a serious gaming experience.


1. How do I choose a good monitor?

Advice on Purchasing an External Monitor for Your Laptop

  • Size of the screen. The problem about computer displays is that they come in a variety of sizes.
  • Resolution
  • LED display, either ultrawide or basic
  • Speakers
  • Height may be adjusted
  • Connectivity and ports
  • Creating your second screen
  • Benefits of a dual-screen setup

2. What size computer monitor should I buy?

Most users will be quite content with a screen size ranging from 24 to 30 inches. They allow you to take advantage of contemporary resolutions and color clarity, and they also allow you to have a couple of different web pages open at the same time without the need for two monitors, which is useful for many professionals.

3. Should I get a 24 or 27-inch monitor?

A 24-inch monitor is appropriate for normal desktop areas with low resolution requirements. The 27-inch monitor is popular for playing high-resolution games and having larger vistas on the screen. It all depends on your room, money, and gaming needs.

4. Can I use a TV as a computer monitor?

To utilize your TV as a computer display, just connect them with an HDMI or DP connection. Then, you have to ensure that your TV is connected to the correct input/source and that your computer's resolution is the same as your TV's. Then, using the cable, connect your computer to your television.

5. Is a 32 inch monitor too big for work?

If you plan on sitting near the display while playing, 32 inches will be too large. A large desk and enough space between you and the display are required for the optimal experience. Otherwise, you will feel stretched and your neck will hurt from having to shift your head around so much.


That has been all you need to know about computer monitors and the best brands that sell it. At the end of the article, we hope you can choose for yourselves the best monitors that fit your needs, your budget, and your workplace design. Thank you for reading the article, and so long for now!
