Why the high refresh rate on a gaming monitor is important

In recent years, the “refresh rate” has been touted as one of the most important features of a gaming screen. And the main reason is that it contributes to the smoothness of the image. However, there are many users who do not pay much attention to this feature.

This is because they usually do not know what a gaming display can offer at a high refresh rate.

If you are considering buying a new gaming monitor, and want to get the most out of your gaming PC or your new console, the following article will analyze what the “refresh rate” is and how it relates to other gaming tech features.

What is the refresh rate?

The refresh rate indicates the number of frames a screen can display in one second (ie how many times the image is refreshed) and is measured in Hz. The higher the refresh rate, the slower the rotation of the moving images on the screen.

As a general rule, the acceptable level of refreshment that results in a satisfactory image depends on the application. Cinemas operate at just 24Hz, while old TV standards supported refresh rates of up to 60Hz. A standard PC monitor provides a refresh rate of 60Hz, but the latest gaming monitors can reach up to 240Hz.

The higher refresh rate is a very important factor in gaming, as it allows the screen to sync with the player’s fast movements. For example, a modern gaming mouse can report its position (Polling Rate) up to 1000 times a second, at the same time that modern gaming PCs can run competitive games such as Counter-Strike: Global Offensive or Fortnite, in hundreds of frames per second.

Having a screen that can keep up with all of the above gives you a great advantage during gaming, especially in competitive games. In addition, once you reach such a refresh rate, other factors become more noticeable when it comes to the extremely smooth image and the best performance in the game. These factors are response time and input latency.

What is the response time

G2G response time (Gray to Gray, gray to gray) refers to how fast the pixels are updated on the screen, ie the time it takes for one pixel to change from one color to another.

Values ​​are expressed in milliseconds (milliseconds, ms) and range from 1ms to 16ms, with an average of 5ms for general-purpose monitors and 1 to 4ms for gaming monitors. The shorter the response time, the less image splitting and color differences we have.

What is Input lag

One issue that most standard PC monitors have – in relation to gaming monitors – is the high input lag. The input lag, also known as the input latency (measured in ms) is the time elapsed between the time the display receives the image signal until it is displayed. For movies and videos, those few milliseconds are not that noticeable.

However, when it comes to fast gaming this lag can introduce a very slight delay between pressing a key and when the character reacts to the screen. For example, when you press a key in a fighting game and your character does not respond immediately, it means a high input lag. A screen with a high refresh rate (above 75Hz) can dramatically shorten the time required to refresh the signal.

Screen type

The type of display contributes significantly to the above features. Therefore, keeping in mind exactly what each type of display offers, you will be able to choose the model that will combine the ideal for your refresh rate and response time.

ΤΝ (Twisted Nematic)

It is mainly used in LCD monitors and low-cost LEDs. The main advantage of TN monitors is very high refresh rates. There are models that exceed 120Hz and are ideal for tasks that require high refresh rates, such as gaming. A major disadvantage of this technology is its relatively poor color quality and limited viewing angles. However, there are TN screens that provide a good contrast ratio. A typical example is the gaming monitor Gigabyte Aorus KD25F 25 “240Hz.

VA (Vertical Alignment)

VA technology uses a non-homogeneous electric field and two transistors per pixel, effectively blocking light and creating unwanted shadows and contrasts. That’s why screens of this type provide deeper blacks and higher contrast ratios – often higher than those of other LCD technologies. Until recently, a major disadvantage of VAs was that when changing the viewing angle there was a marked decrease in color quality. But that has changed. Thanks to models like the MSI Optix MAG241C Curved 144Hz 24 “Monitor.

IPS (In-Plane Switching)

Unlike VA and PVA, IPS displays utilize a homogeneous electric field that provides the faster signal transfer. This results in faster response times. At the same time, the wide viewing angle delivers even more ‘vibrant’ and bright images without any disruption. The only disadvantage of these panels is the lower refresh rates than TN. However, even in this case, the latest IPS screens – such as LG’s 34UM69G-B 34 “Monitor – appear to have eliminated this effect.


The high refresh rate is combined with fast response time and low input delay so that images can be displayed on the screen much faster. So, you get faster reflexes, more accuracy, and stay ahead of the competition.

You can choose a model that combines all of the above without necessarily being the most expensive in its class. This means that everything depends on your needs. For example, a model like the LG 27MK400H-B 27 “Monitor can offer you a higher refresh rate than a” standard “screen and lower response times to enjoy smoother gameplay and a clearer picture. If you’re a more demanding/competitive gamer, then you should definitely focus on models with refresh rates of 120Hz or more.
