Refresh Rate Hz – Definition, Function and Importance in Monitors


Current monitors and TVs, such as Smart TVs that differ in HD and 4K, They have a variety of levels in their repertoire of resolutions. However, until reaching that point of advance a few decades had to pass in which having a television at home was not a novelty. Our perception of what is new or old has been maintained and, in conjunction with this, our eyesight has adapted to recent changes in technology. One of them is the refresh rate possessed by the various video playback devices.

Believe it or not, on these screens and televisions a phenomenon occurs in constant movement both on and off. The human eye detects it but processes it in a way that we don’t realize, and thus in this way we capture the movement.

In these screens, information captured in a peculiar way is transmitted, this is defined as retinal persistence. What this does is that an image remains embedded in our eyes for ten seconds, which allows us to detect movements and depth.

It can be defined as the number of images per second transmitted by a screen or the frequency with which it displays those images. Human sight processes ten to twelve images separated by seconds you perceive it individually. And it happens when a series of images is being reproduced with illumination or lights, the human being begins to perceive tiny interruptions and jumps of approximately ten milliseconds or longer.

How do Hz work inside a monitor?

Basically Hz on a monitor is update speed that it owns for each pixel on the screen per second. As explained above, the refresh rate on a monitor indicates the number of times the image is refreshed over the course of one second.

In other words, the Hz within a monitor work like the speed that video signals have, indicating the number of cycles carried out in one second. The higher Hz a monitor has, the more image quality it can offer as well as higher resolution.

How does the refresh rate influence a TV?

One of the most important things when buying a TV or a monitor is the capacity of the refresh rate. That is, the frames per second that it can transmit, since many devices and consoles require these frequencies, including movies or streaming services. This is because they are reproduced in a larger cup the sixty frames per second.

Smart TV devices like LG currently are designed to be able to process that amount images per second. However, there are still many cheaper televisions that do not reproduce that amount of images. This means that several platforms or services are not at one hundred percent capacity to enjoy this experience.

Within gaming or the world of video games, it has become almost mandatory to have a screen or monitor that can process these frequencies. This is because current applications are optimized to be able to reproduce and function that way. So that it is advisable to have this type of TV or current monitors at the time of running said games, because they efficiently optimize their use.

TVs in relation to consoles also matter. This is because when purchasing a console these come with video games that require such high frame processing and particles on the screen. As well as quite high images per second, being so that half the resolution of a game is fulfilled by the screen and the other half is fulfilled by the console.

What is the use of having a good refresh rate on a TV?

It is used to increase the performance and graphic experience when playing a movie, or in that case, using a video game console. Its function is that the game runs smoothly and smoothly. optimized way. Many of today’s movies require at least 60 to 80 frames per second which is an average frequency rate today.

The human eye is able to capture all this new technology, making the movies or video games that we play look more natural to our current perception. However, sometimes at high refresh rates is less distinguishable or noticeable to see the progress or delay of certain images as opposed to lower numbers of screen refreshments.

In conclusion, we can say that the refresh rate of both a TV screen and a smartphone is vital graphic importance. This is because you need it to play or view content and navigate on VOD or video platforms that require high definition without impairing the display of the image being played.

In this way we improve our experience with recent innovations in terms of graphics and performance, with current monitors being the new window to a world full of audio-visual experiences.

What types of refresh rate are there?

Although the refresh rate is specified for both monitors and televisions, that of the latter is different. This aspect is important when you want to select a TV model. Here we tell you what types of rates exist:

Native refresh rate

It is considered the actual speed at which the TV works, being able to be of 60 Hz and 120 Hz. At present TVs with more than 120 Hz of refresh rate are not manufactured.

Virtual refresh rate

It is the refresh rate images are played back once you know the frames per second it contains. Models with 60 Hz, 120 Hz and 240 Hz can be found today. It is also known as the frequency of interpolated motion.

Dynamic refresh rate

This kind of refresh rate we find it on high-end televisions They can be 960 Hz and 1200 Hz. It is the highest refresh rate that offers a superior user experience.

How can I know the refresh rate of my TV or PC monitor?

To know the refresh rate on a PC monitor, you just have to access the ‘Advanced display settings’. There you can get the information regarding the amount of Hz that your screen has. In the same way, depending on your equipment, you can know the refresh or update frequency through the manufacturer of your video card.

In general, all monitors and TVs have at least 60 Hz. Likewise, in the TV menu you can find information about the refresh rate it has, as well as being able to change it, depending on the model.

Knowing the update rate of your PC or TV will allow you to be aware of how much quality it can offer you. That way, you can consider this aspect to acquire a monitor that gives you higher sharpness and fluidity. On the other hand, a high native refresh rate will offer you clear and consistent content.
