How To Choose The Best Gaming Monitor Under $ 150 - Here's Buyer's Guide 2022
Choosing a gaming monitor suitable for a gamer is not easy, there are so many models on the market, starting from the cheapest ranges up to the TOP of the range.
Each screen has different characteristics, for example, a gaming monitor has completely different technical specifications compared to a monitor intended for office or graphic use.
In this guide, we will explain which features to aim for to help you choose.
So here's what you need to take into account to choose the best gaming monitor.

The size of the screen is important, as you have to calculate the space available before aiming at a large monitor.
If the desk on which you are going to place the monitor is not very large and you buy a 27 inch, you will have a problem regarding the sharpness of the image, as with the same pixels, the images are much larger.
So, if you don't have a space problem and are looking for a large gaming monitor, a nice 27-inch may be suitable.
While if you have any problem with spaces, a 23 or 24 inch is ideal for you.
You must take into account in this choice, that it is not so much the space needed to the right and left of your screen, but the distance from your eyes. It won't do you any good to have a giant monitor if you have it stuck to your face.
Another problem you can face by playing too closely on a large monitor is that of risking eyestrain, which will cause you headaches and insomnia in the first place.
In gaming monitors it is not only the screen size that matters, another important thing is in fact the resolution.
There are 3 main types of resolution:
- Full HD monitors: Usually they are the best on the quality/price ratio. They have a resolution of 1920 x 1080p (pixels), and it is the current standard.
- 2k monitors: This type of monitor uses a resolution of 2560 x 1440 pixels, and more than for gaming, they are usually recommended for graphic use.
- 4K or Ultra HD monitors: It is the highest resolution you can currently find on the market, they have a resolution of 3840 × 2160p. To make the most of all this you need a powerful PC, otherwise, your graphics processor will not be able to guarantee you a good gaming experience, the suggested sizes range from 28 inches upwards.
Most of the displays currently on the market are liquid crystal (LCD), with LED backlighting, but be careful, not all are the same, in fact, they are divided into three main categories:
- The monitor TN: The most suitable for gaming saw the low response times that have (up to 1 ms) and because of their quality/price ratio.
- The monitor IPS: This type of panel is more appropriate instead for graphics or areas where it is important to the quality of the colors, better than other types such as TN or VA, while the reaction time is usually higher.
- VA monitors: More suitable for use for work, as they have response times and colors that are not as good as the other panels, however, they are equipped with a good viewing angle and better contrast.
A very important factor for a gaming monitor is precisely the response time, or the ability of a single-pixel to change color starting from gray to color and returning to the starting gray.
This factor is one of the main evaluation factors for a gaming monitor. A competitive, high-level player usually stays on 1 - 2 ms, but for an untrained eye, even one with 5 ms makes no difference.

The best interface to use with the gaming monitor is the DisplayPort, as it guarantees you excellent transmission of the 144Hz video signal.
Otherwise, you can choose DVI which, however, carries only the video signal and not the audio one, or alternatively you can always use the HDMI interface, very popular on consoles.
With version 2.0, HDMI has reached very high refresh rates, obviously, both the cable, your video card, and your monitor must be able to support this interface.
The brightness of a gaming monitor is a very important factor to evaluate, as it allows you to be able to have good visual quality even when there is a lot of light in your room.
The standard brightness is 250 cd / m 2 but you could also go to a 300 cd / m 2 , but be careful because a high brightness can cause damage and discomfort to the eyes.
Note: However, remember that if your screen supports high brightness, you can always lower it, but not the other way around.
A high contrast, on the other hand, allows you to see well especially in low-light games, such as thrillers or horror games.
For very clear games, set during the day, for example, such as MMORPG or RPG, there is nothing better than a low contrast, otherwise, the view will tire.
Most of the most hardcore players set the possibility of changing the contrast in real-time, so as to always be at the top with the graphics.
Remember that high contrast is always better because you can choose to lower it to your liking.
Refresh rate (refresh rate)
It is usually expressed with the abbreviation Hz (Hertz), and the higher this factor is the smoother the video images flow.
Noting the difference for untrained people after 60Hz is not easy, while for those who already know more, values between 120 Hz and 144 Hz are preferred, but there are also monitors with higher values.
There are two types of displays, those with a glossy or matte finish.
Those with a matte surface allow you not to see those annoying white beams due to light, while the glossy ones have brighter colors themselves but suffer more from the light effect.
So, if the room you play in is very bright I recommend a matte display, while if the monitor is not subject to a lot of light, a glossy display is the most suitable.
A curved screen provides a great field of view giving you a more immersive and better gaming experience, great for first-person games, even if they are priced slightly higher than a flat one.
The best gaming monitors have several very useful technologies and features.
For example, in some models, you can make a viewfinder appear in the center of the panel, or view the FPS in real-time.
Low Blue Light technology will reduce blue light frequencies at your command, allowing you to relax your eyes.
The blue frequencies are the most harmful to our body and are the main cause of migraines and sleep disturbances.
Even the best brands in the industry have created real suites within the gaming monitor, integrating various features. They will be very useful to you during your gaming sessions, giving you a lot of advantages.
What Is The Best Monitor For 150?
With a budget of $150, you can find some good options for a basic monitor with decent features. Here are a few options:
- ViewSonic VA2259-SMH: This is a 22-inch full HD (1920x1080) IPS monitor with a slim bezel design. It has a 5ms response time and a 60Hz refresh rate, making it suitable for basic tasks and casual gaming. It also has a built-in speaker.
- Acer SB220Q bi: This is another 21.5-inch full HD IPS monitor with a 75Hz refresh rate and a 4ms response time. It has a slim design and thin bezels, making it suitable for multi-monitor setups. It does not have built-in speakers, but it does have VESA mount compatibility.
- AOC E2270SWHN: This is a 21.5-inch full HD TN panel monitor with a 60Hz refresh rate and a 5ms response time. It has a slim design with narrow bezels and also has built-in speakers. It's a good option for basic tasks and casual gaming.
These are just a few examples of monitors that you can find within your budget. Keep in mind that at this price point, you may have to compromise on some features such as screen size, refresh rate, or response time.
Is 24 Or 27 Better For Gaming?
The choice between a 24-inch and 27-inch monitor for gaming ultimately depends on personal preference and gaming setup.
A 24-inch monitor is generally considered the standard for gaming as it provides a good balance between screen real estate and pixel density. It's also a popular choice for esports gamers who prefer a smaller screen size to focus on the action.
On the other hand, a 27-inch monitor provides a larger screen real estate and can enhance the immersive gaming experience. It can also be beneficial for games that require more detail, such as strategy games.
It's important to note that the ideal screen size also depends on the viewing distance. If you sit closer to your monitor, a smaller screen size may be more suitable, while a larger screen size may be more comfortable if you sit further away.
Ultimately, the choice between a 24-inch and 27-inch monitor for gaming comes down to personal preference, gaming setup, and viewing distance.
Is 27-inch Gaming Monitor Good?
Yes, a 27-inch gaming monitor is a good choice for gaming as it provides a larger screen real estate, which can enhance the immersive gaming experience. A 27-inch monitor also allows for better multitasking and can provide more space for other applications such as web browsing, video editing, or programming.
Additionally, most 27-inch gaming monitors offer a higher resolution, such as 1440p or 4K, which can improve image quality and provide more details in games. Some models also offer faster refresh rates and response times, which can reduce motion blur and provide smoother gameplay.
However, it's important to note that a 27-inch monitor may not be suitable for all gaming setups or preferences. If you sit close to your monitor or prefer a smaller screen size, a 27-inch monitor may feel too big or overwhelming. Similarly, if you have limited desk space or a small gaming setup, a 27-inch monitor may not be the best choice.
Overall, a 27-inch gaming monitor can be an excellent choice for gamers who want a larger screen size and improved image quality, but it's important to consider personal preferences and setup limitations before making a decision.
Is 60hz Good For Gaming?
While a 60Hz refresh rate was once considered standard for gaming, it may not be the best option for many modern games. A higher refresh rate, such as 120Hz or 144Hz, can provide a smoother and more responsive gaming experience. However, the choice of refresh rate ultimately depends on the type of games you play and your personal preferences.
If you primarily play slower-paced games like strategy or turn-based games, a 60Hz monitor may be sufficient. But for fast-paced games like first-person shooters or racing games, a higher refresh rate can make a noticeable difference in the smoothness and clarity of the gameplay.
Are 3k Monitors A Thing?
Yes, 3K monitors are a thing. The term "3K" typically refers to a resolution of 2880 x 1620 pixels, which is slightly higher than the standard 1440p resolution of 2560 x 1440 pixels. While 3K monitors are not as common as 4K or 1440p monitors, they can offer a good compromise between resolution and performance for those who want more pixels than 1440p but don't need the full 4K resolution. Some popular 3K monitors include the Dell UltraSharp U2713H and the HP Z27q.
Is A 75 Hz Monitor Good?
A 75 Hz monitor can be good for gaming, but it depends on your specific needs and preferences. In general, a higher refresh rate can offer a smoother and more responsive gaming experience, particularly in fast-paced games. A 75 Hz refresh rate is a step up from the standard 60 Hz refresh rate, so it can provide some noticeable improvements in motion clarity and reduced input lag.
However, if you are a professional gamer or you play competitive games, you may want to consider a higher refresh rates monitor, such as 144 Hz or even 240 Hz. Additionally, the other specifications of the monitor, such as resolution and response time, should also be taken into account when choosing a gaming monitor.
Do Pro Gamers Use 1080p Or 1440p?
Pro gamers typically use 1080p or 1440p monitors, depending on their preferences and the specific game they are playing. Some competitive gamers prefer the lower resolution of 1080p because it allows for higher frame rates and smoother gameplay. Others prefer the increased detail and sharpness of 1440p. Ultimately, the choice between 1080p and 1440p comes down to personal preference, the hardware being used, and the demands of the specific game being played.
What Size Monitor Is Best For Fps?
When it comes to FPS gaming, a smaller monitor size is generally better because it allows for faster eye movement and quicker reaction times. The most popular monitor sizes for FPS gaming are between 24 and 27 inches. However, this is also a matter of personal preference and the size of your gaming space. A 24-inch monitor may be sufficient for some players, while others may prefer a larger display. Ultimately, the size of the monitor should be chosen based on the individual's comfort and preferences.
Is 144 Hz Good For Gaming?
Yes, 144 Hz is considered good for gaming as it provides a higher refresh rate compared to the standard 60 Hz monitors. With a 144 Hz monitor, the screen can display up to 144 frames per second, resulting in smoother and more responsive gameplay. This is particularly beneficial for fast-paced games such as first-person shooters, where quick reflexes and precise movements are crucial. A 144 Hz monitor can also reduce motion blur and input lag, making it easier for gamers to keep track of the action and respond to it quickly.
What Hz Is Good For Gaming?
Higher refresh rates are generally better for gaming as they provide smoother and more responsive gameplay. A 144 Hz refresh rate is considered to be a good standard for gaming, but some gamers prefer even higher refresh rates such as 240 Hz. However, the ideal refresh rate depends on the individual's preferences, the type of games being played, and the hardware being used.
Does Monitor Size Affect Fps?
Monitor size does not directly affect FPS (frames per second). The resolution and refresh rate of a monitor can affect the FPS in games. For example, a higher resolution monitor may require a more powerful graphics card to run games at a higher FPS, while a higher refresh rate monitor may provide a smoother gaming experience with less screen tearing. However, the physical size of the monitor does not directly affect the performance of the game.
Is 2k The Same As 1440p?
Yes, 2K and 1440p are the same resolution. The term "2K" typically refers to a resolution of 2048 x 1080 pixels, which is slightly wider than 1080p (1920 x 1080 pixels). However, in the context of monitors and displays, "2K" is often used interchangeably with 1440p (2560 x 1440 pixels), which is also known as Quad HD (QHD).
Now that you know the most important features that a gaming monitor must-have, all you have to do is choose the one that best suits your gaming situation.
For a good quality/price ratio I recommend a FULL HD with a response time ranging from 1 - 2 ms, with a frequency of at least 120 Hz (if you are not a hardcore gamer, 60 is fine too ), so that you have a good graphic rendering without the need to spend a large amount.
