Best gaming monitor under 400$ for 2021

The monitor is the only piece of hardware that lets you see what you’re doing, so it makes sense to invest in a high-quality display. However, finding the best gaming monitor under 400$ can be difficult because there are so many factors to consider-resolution, refresh rate, response time, and more. We’ll help you compare the top models on the market based on these features so you can find your perfect TV!

What to Expect in the 400$ Budget

Before we talk about the characteristics you should expect from a monitor, let’s first see what the best monitors under 400$ have to offer.


The first thing you’ll want to decide on is your resolution. The majority of gaming displays have some sort of widescreen format, either 16:9 or 16:10. However, some displays have a 4:3 format, so keep an eye out for that when you’re shopping.

The best gaming monitor under 400 dollars usually comes with 1920 x 1080 resolution, which is perfect for most gamers.

Screen Size:

The best gaming monitor under 400 usually comes with a screen size of 24″, 27″, or 31″.

Refresh Rate:

Once you’ve decided on your resolution/aspect ratio, you’ll need to consider the refresh rate. Refresh rates are usually displayed in Hertz (Hz), and the best monitors under 400 are usually between 60-144 Hz.

Response Time:

The response time represents the amount of time it takes for a pixel to change from black to white, or in other words, how long it takes the monitor to display an image. A good gaming monitor under 400 usually has a response time of 1 – 6 milliseconds.

Display Technology:

The two most popular display technologies are TN and IPS. The best gaming monitor under 400 usually comes with a TN panel, which is more affordable but not as good as the more expensive IPS panels.

G-Sync vs Freesync

There are two types of syncing technologies-G-Sync and Freesync. Both of these technologies are made to combat screen tearing, which occurs when your monitor can’t keep up with the frame rate sent to it by your computer. This is because displays run at a fixed frame rate (usually 60 Hz) while computers can render frames at varying speeds. The result is that when your computer sends a frame that requires different speeds to render, the monitor can’t keep up and ends up displaying multiple images on your screen at once.

G-Sync is made by Nvidia, so you’ll need an Nvidia graphics card for G-Sync to work. With a G-Sync display, you simply connect your graphics card and run games. Your monitor will be able to keep up with the output from your graphics card and you won’t get screen tearing.

If you’d rather not pay for a G-Sync display, then Freesync is your best option. You’ll need an AMD graphics card to use Freesync. With a Freesync display, you connect your graphics card and run games. The graphics card will then send a signal to the monitor telling it what refresh rate to use. This system isn’t as refined as G-Sync, but it still works pretty well and you can get great monitors under 400$.

IPS, TN, or VA panel?

IPS panels provide better viewing angles and color accuracy than other panels types-perfect for movies and games. The main downside of IPS panels is their response time, which can be up to 10ms compared with 1 or 2 ms on TN panels.

TN panels are the opposite of IPS panels in many ways. They have much faster response times (1-2 ms) but they don’t look nearly as good when it comes to color accuracy or viewing angles.

VA panels fall somewhere between IPS and TN panels in terms of their contrast ratio, color accuracy, response time, and viewing angles. Their main drawback is the black-light bleed commonly seen in VA monitors. This can cause blacks to look greyish and the washed-out effect can be annoying.

FreeSync or G-Sync monitor?

If you have an AMD graphics card, then it will be easier to find a good Freesync monitor for under 400$. If you have an Nvidia graphics card or if money is no object, then G-Sync is the way to go.

There are a few more things to think about:

  • Refresh Rate: Refresh rate refers to how many times per second a monitor can change the image on its screen. It’s measured in Hz, and 60 Hz is the most common for TN panels while IPS and VA panels usually come with 75-120 Hz as standard.
  • Resolution: Your monitor’s pixel density determines how clear and sharp everything looks. The higher your resolution, the more detailed your games will look and the easier they’ll be to see from a distance.
  • Panel Size: Bigger monitors mean more immersive experiences but they also require more desk space! It all comes down to personal preference, but 27-inch monitors are usually a good size for gaming as long as your monitor doesn’t butt up against your keyboard or mouse.

What is an HDR monitor?

HDR monitors are becoming more common, but many people aren’t sure what they are or why they’re important. HDR stands for High Dynamic Range, which means that the monitor has a wider range of colors that it can display. The end result is an image with better colors and greater detail in both bright and dark areas compared to non-HDR monitors.

HDR displays can be difficult to find under 400 dollars, but you should keep an eye out for the next generation of HDR consoles coming in 2020. If you’re planning on buying one then it might be worth spending a bit more money on an Xbox One X or Xbox One S console that would support your monitor.

What is a 4K monitor?

A 4K monitor is a display with a 3840×2160 pixel count, which means it has an 8.3 million pixel density. This allows your games to look sharper and more detailed while also providing better colors and contrast compared to 1080P displays. However, not all 4K monitors are created equal-some have lower pixel densities and can’t display as much detail.

For the best 4K gaming experience, we recommend finding a monitor with a pixel density of around 163 ppi (pixels per inch). You should also make sure that your graphics card has enough power to output at least 60 Hz in games (unless you plan on buying an Xbox One X or Xbox One S console).

Screen tearing vs. stuttering

The main difference between screen tearing and stuttering is that you’ll see tearing during games with V-sync turned on, while there will be more noticeable stuttering during games If you have G-Sync or Freesync enabled. Stuttering happens when your computer can’t produce enough frames per second to match your monitor’s refresh rate (which makes everything look choppy or stuttery) while screen tearing happens when the monitor and graphics card are out of sync with each other.

Screen tearing is generally worse than stuttering, but you can minimize both problems by turning on G-Sync/Freesync, lowering your game’s resolution, or upgrading your graphics card.

What you should keep in mind when selecting the best monitor for gaming.

Generally speaking, you’ll want to focus on a few key features when choosing a gaming monitor: Resolution Refresh Rate Panel Type Response Time Contrast Ratio Ports Color Accuracy Size Aspect Ratio

If one of these factors is really important to you, then it’s worth spending more money to get a monitor that excels in that category.

What aspect ratio should I choose?

Aspect ratio refers to the shape of your monitor’s screen. The most common aspect ratios are 16:9, 21:9, and 32:9. Monitors with a 16:9 or 21:9 ratio will look good for movies and widescreen TV shows while a 32:9 will be better for watching movies in a theater. However, for gaming you should probably choose 16:9 or 21:9, as monitors with a 32:9 ratio suffer from picture distortion.

What is the difference between an IPS and VA monitor?

IPS (In-Plane Switching) and VA (Vertical Alignment) displays are two of the most common modern display types, but there are some significant differences between them. IPS monitors generally have better colors, viewing angles, and contrast than VA displays, but they’re often more expensive. VA monitors offer better response time and refresh rates than IPS displays, but their poor viewing angles can be distracting in certain games or video/movie content.

If you prefer the best possible colors and viewing angles, then go for an IPS monitor. If you care more about the refresh rate, response time, or price of your monitor, then a VA panel might be a better option.

What is a good gaming but cheap monitor?

A good gaming monitor should feature the following: A low response time so you can react more quickly in games Refresh rate support (typically 60Hz) G-Sync/Freesync Variable sync technology (to minimize screen tearing) Good contrast and brightness levels for visibility

If you want to save some money, then you might be able to get away with 1080p resolution. However, in order to get the best possible gaming experience, we recommend looking for a monitor with at least 1440p resolution and a response time of 5 ms or less.

What is the difference between LCD and LED?

LCD monitors use Liquid Crystal Display panels to display images while LED screens use Light-Emitting Diodes as backlighting. LED monitors usually have a better contrast ratio, wider viewing angles, and better brightness than LCD screens. In addition, some LED models feature G-Sync/Freesync variable sync technology for even smoother gameplay.

What color is best?

Unfortunately, there isn’t a clear answer to this question because it depends on what you’ll be doing with your monitor. If you want the best possible contrast, brightness, and viewing angles, then an IPS display may be your best option. However, if you don’t mind sacrificing color accuracy then VA monitors are also great options that usually have better response times than IPS displays.

Which is better for gaming?

There isn’t a clear answer to this question because it depends on your budget and what you’re using the monitor for. If you want the best possible gaming experience, then we recommend choosing an IPS or VA monitor with low response times and variable sync technology (G-Sync or FreeSync). However, if you don’t mind sacrificing some of these features for faster performance, then you might prefer a monitor with a slower response time and better refresh rate (120Hz or higher).
