Why do Pro Gamers Use Small Do Monitors?

An enlarged image unavoidably creates more stress on the monitor displaying it. So, the computer might not have the power to produce the image without any lagging. For this reason, most gamers maintain a screen range of 18-22 inches for improved performance.

Is it Better to Play Games on a TV or Monitor?

Where screen responsiveness is crucial, mostly in competitive gaming, a monitor is the most ideal because it’s capable of faster reactions. However, if a large picture is a priority and distortion or minor lagging can be ignored, then TVs can serve the purpose.

Why Do Gaming Pros use 24” Monitors?

You need a perfect balance between several essential values in a gaming monitor, like aspect ratio, field of view, performance, resolution, or how far you can sit from the monitor. You can find good gaming monitors for under $400 that measure more than 24-inch. However, this would mean large pixels and more stress on the processor, and so on.

How Many Monitors Do You Need to Stream?

Some gamers need a dual computer setup, so a second monitor results from your mode of operating. Some professional streamers work with more than two screens. Two screens are meant for gaming and the others for streaming.

Gaming Monitor Buying Guide

Choosing the best budget gaming monitor can be challenging and daunting for many gamers, as there are many specifications and options to take into account.

To get the best out of your latest video games, you’ll not only need a gaming monitor that has a powerful CPU and graphics card, but you’ll need one that will help you take the lead over your opponents. In this guide, we’ll help you navigate the sea of gaming monitors.

Monitor Size and Panel Type

As in the case of many devices, the bigger it is, the more it’ll cost. However, for our wallets, bigger isn’t the best. When considering the monitor size, you have to consider its weight. A bigger monitor is usually bulkier and makes it difficult to use depending on your gaming setup. You should also consider the weight distribution of the monitor. If it comes with a heavy top, it’s at risk of tipping over at the slightest shake.

When choosing a gaming monitor, you should also consider the panel type. This refers to how the monitor is lit. Different panel types have various perks. Most gaming monitors are TN types, which is the most responsive type. The TN panel typing is ideal for gaming since it has fast response times.

Response Time

A monitor’s response time dictates how quickly the image will respond to your inputs. If the cursor moves 5 ms after moving the cursor, then your monitor has a 5ms response time. If you’re a gamer, you can easily differentiate between a fast monitor and a slow one based on the gaming feeling. The response times you’re looking for should lie between 1-5 milliseconds, with a lower number ranking high.

Design and Connectivity Options

When looking at two monitors with similar specifications, the only things that differentiate them are the designs and connectivity options. The monitor’s design refers to how it’s comfortable when using it. Is it height adjustable? Can it tilt or swivel? Is it compatible with wall mount or VESA mounting? These are things to look out for.

Additionally, no one wants a monitor that does not use a VGA port. The monitor should have an HDMI that supports high refresh rates.

Image Quality and Resolution

The image quality displayed on the screen depends on the resolution you’re operating at. The higher the monitor’s resolution, the clearer the images you will see. A full HD resolution can display a 1920×1080; this resolution can be referred to as 1080p.

If a monitor has a low pixel density, the image quality may be pixelated, meaning that there will be limited screen space plus a lack of details. If it’s too high, the monitor will have a lot of space and detail. However, you’ll have to scale the images for a small text to be readable. This isn’t a big problem as you can determine whether to sacrifice screen space for crispier and larger details or not.

Refresh Rate

The refresh rate is the rate at which your monitor displays images. It is measured by how many different images can be displayed in an interval of 1 second. The most common refresh rate is 60Hz. If you’re searching for a gaming monitor, go for one with the highest refresh rate, anything between 60Hz and 144Hz will serve you best.

Adjustable Stand and VESA Mounts

One specification that many gamers ignore when looking for a monitor is the stand quality. A good stand will allow you to tilt it backward and forward and help you shift the monitor up and down.


There are many confusing choices and more confusing marketing terms for gamers looking for the best gaming monitors.

If you’re looking for a perfect gaming monitor, this guide will help you get the right monitor that suits your needs and preferences without breaking the bank.
